Now that we have heard from all the 'organics', lets hear the other side of the
story. There are certain insect pests that cannot be effectively controlled with organic methods. I know because I have been growing fruit for over 20 years and have tried all the organic sprays and controls. I still utilize a combination of organic methods, like trapping insects on sticky balls and dormant oil. I have yet to find an organic method to effectively control apple maggot, for starters. Like any other technique, spraying can be done correctly, or not. You should not spray insecticide (fungicide is ok) when your trees are in blossom. That indeed will kill any bees around. You should not locate your trees near your vegetable garden. You should spray on near windless days, so that it stays confined to your orchard area. You should wear protective gear, including breathing masks, and not spray when kids or pets are around. This all makes it sound a bit dangerous, but so is getting on the freeway with all the idiot drivers. If you want the majority of your fruit to be clean, you probably have to spray in your location, especially since you have already noticed what sounds like heavy insect damage. I would recommend a general orchard spray (Bonide makes one, for example). It contains a combination of insecticides and fungicides. These types of sprays are meant to cover most orchard problems, but if you have a more serious situation, you may have to go to a specific spray which targets it. Try the orchard spray first, and then see how it goes. You may have had a better reception if you had gone to rec.gardens.edible, where there seems to be more people growing fruit.

Actually, Betty, I have made enough mistakes to fill a book. I know what I
don't know, I know when I need advice, and I *do* ask questions. But, since 1970 or so, when I began gardening, all anyone needed to do was open a newspaper 20 times a year to notice that there are serious problems with pesticides, and that their presence on the store shelves is absolutely no indication that they are safe. Further, to ask about "how to kill ALL bugs" indicates a level of ignorance that's truly surprising in this day and age. "Betty Harris" wrote in message oups.com... As we all know, Doug has always been a expert gardner. He has never been a neophyte and has never made any mistakes and has never had any questions. Anyone who cannot meet these standards is not welcome in his world. Betty |

Those instructions include dosages, personal protective equipment requirements and minimum re-entry intervals. I will add another pest that cannot be controlled by organic methods nor by unrestricted pesticides such as the Bonide Fruit Tree Spray. That is the plum curculio which attacks not only plums, but also apples, pears, peaches and nectarines. Unrestricted pesticides used to contain a control for plum curculio but that was removed from the formulae two years ago. The unlicensed homeowner has no effective remedy for plum curculio, at least in my state of New Hampshire. That is one of the reasons I got an applicator's permit this year. Imidan is an effective control for plum curculio but it is a restricted product. JMHO John |

I know because I have been growing fruit for over 20 years and have tried all the organic sprays and controls. The best method of apple maggot control is the use visual traps for the adult flies before they lay their eggs, ADDING a natural host odor with the trap [Rull et al, Entomologia Experimentalis et Applicata, January 2005 -- note the date, it is very recent research that has shown the effectiveness of non-sparying techniques]. While it has become a cliche that no organic spray is half as effective as highly toxic organophosphate type pesticides, it is now well established that methods other than spraying can be completely effective. Because crop value is higher for organic crops, there is no net gain by using potent toxins [Reissig, Journal of Economic Entomology, Oct 2003]. Once a grower realizes spraying is not the best or primary method (organic or otherwise) comparisons of organic vs non-organic spraying becomes moot. But fact is, the 2001-2002 Cornell study headed by Terence Robinson of organic apple techniques (tested in New York & Ontario) discovered control of apple maggot with organically approved Surround was completely effective. So the popular cliche that only harmful organophosphate insecticides work is now conclusively known to be false. Comparative analysis in Quebec conducted over a ten year period found that completely unsprayed apple orchards had infestation rates ranging from 0 to 4.1% [Vincent & Mailloux, Annales de la Societe Entomolique de France, 1988; Vincent & Roy, Acta Entomologica et Phytopathologica Hungarica, 1992]. Unless losses exceed 5% it is counterproductive & unnecessary to even consider chemical spraying. Any gains from using toxins are more than offset by the extra costs of chemicals plus the lowered value of non-organic crops. If apples were not permitted to rot on the ground, the orchard would not have any apple maggot pupae overwintering in the soil, & the only threat of infestation is from adult flies coming from outside the orchard. Often removal of elderly apple trees & hawthorns from surrounding properties is the only control required. In all cases, by the time eggs are laid, the maggots are impervious to toxins; so stopping the adult flies at the periphery becomes the goal. Even growers who do use pesticides often use them exclusively OFF the periphery of the orchards & NOT on the trees themselves [Thimble & Solmae in Crop Protection, 1997] since a clean orchard has no emerging flies inside the periphery. Others who use insecticides do so only in the scent-baited sticky-traps again to keep poisons off the crop. The milestone research of the late Ron Prokopy (who died last year) with even just unscented traps triggered a revolution in organic apple growing that left the chemical-dependent growers in the pesticidal dust. Chemical dependency bred chemical dependency, & here in Washington as the chemical-dependent growers went bankrupt one after another, organic growers flourish. The more recent (even just within the last four years) scent-baiting of the Prokopy traps has has made trap strategies so extremely effective that organic apple growers have either fewer or no more losses than lazier less knowledgeable growers who spray & thus produce a less valuable harvest. Effectiveness of Prokopy sticky traps PLUS host scent is today the preferred method of apple maggot control, preserving the added value of organic crops. The big reason some orchards would still spray today is because they are producing pig-feed apples & it is too labor intensive both to maintain bait-scented traps & to clean up fallen apples, when in any case the crop will remain poorly valued. In Washington state the primary threat to fully organic apple orchards are infestations bleeding over from trees grown in the back yards of homeowners who do not know to control apple maggot with scented stickytraps, & who let fallen apples remain on the ground so that the next year's infestation developes. Sponsored programs to involve morons, I mean backyard amateurs, in the use of scented traps, even providing the traps for free, & educating the amateurs on the necessity of immediately cleaning apples off the ground before the worms crawl into the ground to pupate, is far more effective than trundling out increasing numbers of increasingly toxic chemicals & pretending there is no way around them -- though certainly the chemical industry's propoganda encourages that misguided belief. Only the chemical companies themselves continue promulgate the so-called "integrated" system of traps plus toxic spraying. -paghat the ratgirl I still utilize a combination of organic methods, like trapping insects on sticky balls and dormant oil.

I'm aware of the dangers inherent in driving my car or riding my motorcycle, too. That doesn't stop me from doing so. Nor of having an almost perfect driving record for 55 years (a couple of speeding tickets). Your attitude strikes me as fanatical. There are times when pesticides are called for. And different compounds used have greatly varying toxicities. For example, Sevin, which is quite toxic, is the only thing I've found that will knock out elm beetle grubs before they deleaf my elm trees. I wear coveralls and a respirator when I use it, usually once a year. Malathion, OTOH, is relatively inoucous and I use it to kill thrips and aphids on my rose bushes and Japanese honeysuckle with short sleeves, no gloves, and no respirator. I realize this won't convince you, but I wanted to make others aware that not all of us are environmental fanatics or, on the other side, reckless rednecks who spray evrything in sight with the deadliest stuff we can find. So that's all I'm going to say on the subject. What convinces me is stories such as you tell of always needing so always using all sorts of toxins for all sorts of garden problems. i never use them, never need them. My elms are healthy, the roses are healthy, the honeysuckles are healthy, never been assaulted by thrips, have gotten rid of aphids with nothing more than a couple drops of dishwashing soap in a gallon of water, sometimes just with the water. Why is that my garden does fabulously & never requires ME to get a respirator, moon suit, & five kinds of toxins to spray about? God loves me but hates you? I'm lucky, you're not? Or are we both experiencing the results of our own actions? It's quite clear that chemical dependency breeds chemical dependency by throwing gardens completely out of balance. The longer one gardens organically, the better that semblance of natural balance that could never be sustained in a soup of recurring toxic assaults. Chemical-dependent gardens are perpetually stressed from being perpetually out of wack. Toxins have killed so many beneficial insects & soil microorganisms & so weakened the plantlife that all such a gardener can do is try to patch over the damage with the same array of toxins that caused the damage. Thrips tend to be a greater problem where beneficial insects have been removed from the environment -- predator insects are always slower to return than are pests, so pests return rapidly & further toxification is undertaken before even the slightest semblance of balance can be restored. And anyone who thinks they need malathion for aphids just isn't thinking about these things rationally; it's like if an itchy toe could be fixed by scratching it for a couple seconds, & you decide to bang on it with a sledgehammer as the best line of defense. I have to assume the other chemical decisions were as unsoundly based, because the rational you've dismissed as radical. You posit a worst-case scenario of thrips stripping elms, yet you can't kill elm thrips without also killing a whole array of beneficial insects thus making the environment MORE inviting to thrips for the next cycle. The LASTING method of thrip control is with predatory mites, soil mites, lady beetles, & nematodes -- but everytime you toxify the environment instead, you destroy a dozen beneficial components of the environment sledgehammering the one harmful pest, thus causing the problems to escalate year by year rather than diminish. It's amazing to me that people in love with their toxic methods call those of us who don't use toxins "radical," yet you keep getting pests in your garden while I do not. If there were legitimately a problem in my garden that only synthetic toxins had any chance of taking care of, I would consider that option, but I've gardened since the 1960s & over time even the "exceptions" I once thought were necessary were not exceptions at all. An organically balanced garden is a healthy garden. A chemical-dependent garden is not. It sometimes takes more patience with organic methods -- in three years it is possible by biological means to get rid of Japanese beetles once & for all, but people who prefer toxins will be using them forever annually patching over a problem that will never cease. To me you sound like the radical, not because you require toxins so much as you require blinders. You believe you can't get rid of aphids without synthetic pesticides, so why is that I can do so very easily. You have harmful pests that you believe cannot be controlled without harsh pesticides, but I have so few harmful pests that their damage, if any, is never visible. You have to spray your shrubs & trees because they are attacked by pests & disease, but mine are neither diseased nor infested though I do not spray even with organically approved pesticides let alone the nastiest stuff you rely on. Why would your garden be so doomed without annual applications of sundry toxins, but mine thrives without them? I don't believe I'm just lucky & you're cursed by God; their are rational reasons for my not having the problems that afflict your garden, & those reasons are methological. You've made an emotional or political decision (rather than a reasoned or scientific one) to dismiss effective methods as "radical" if they do not require toxins. And so yhou put on your moonsuit & respirator to take care of problems that keep recurring because of your actions. That's very much like banging your head into a wall & when you discover your head is injured, bang it a second, third, & fourth time, never realizing the problems are returning because of, not in spite of, your actions. -paghat the ratgirl -- Get your Paghat the Ratgirl T-Shirt he http://www.paghat.com/giftshop.html "In every country and in every age, the priest has been hostile to liberty.

Some may praise paghat but she is is off the mark this time and has demeaned me with false accusations. Bad paghat! John If I partially confused your error about plum curculio with Sherwin's error about apple maggots, my apologies. When you made the untrue statement about plum curculio, you called it "another" pest that required synthetic chemicals to control. I assumed by "another" you were insisting apple maggots as mentioned earlier in the thread required toxic sprays, & "another" one that required it was plum curculio. If you had a third pest in mind I missed it somehow. I'll post the relevant information on plum curculio further below, it'll make a good match for the citation-riddled data on organic control of apple maggots I already provided. But your denying the cowshit post is more fun just now: If you never made the "farmy smell" post there must be two John Bachmans. Ever since you or your evil twin posted about the glories of the farmy smell of cow manure, Granny Artemis & I have incorporated the phrase "ahhh, that lovely farmy smell!" as our recurring synonym for "cowshit" every time we drive by a dairy. I just this minute did a google-groups search on the phrase "farmy smell" to find out if I'd been miscrediting that lovely discription of cowshit to the wrong fellow. I only got one hit, & it certainly appears to be you saying how much you enjoy the "farmy smell" of cow manu http://groups-beta.google.com/group/rec.gardens.edible/msg/813bab6a3eab3f95?dmode=source&hl=en Having long ago lived next door to a dairy for a year, these sorts of references stick in my memory. I may even write a cowshit article for paghat.com someday, I've got many garden notes about cowshit just waiting to organize. In fact I lived between a dairy & the now defunct Longacres race track, & between the odors of horse shit & the cowshit, the horseshit was sweeter, but to each his own. Why you wouldn't want to be admired for liking the smell of cowshit best puzzles me. Even Garrison Keeler would agree with you, in his spoof of a Copeland diddy, ending on the sentimental lyric: "Proud and sure, cow manure, I know where I am," for which I wish I possessed the entire lyrics. I think I remember pretty correctly your recurring advocacies of the right chemical properly used, though that certainly was not an exact quote as "farmy smell" was. Maybe you just don't know how your advocacy sounds sometimes. Very much in keeping with your post in this thread asserting that following label instructions renders all pesticides totally safe -- that's just untrue. The reality is that "used as directed," pesticides & herbicides have done great harm to watersheds & lakes & locally to Hood Canal, it took no off-label use to do great harm. Used strictly as directed, these chemicals have accumulative effects which label instructions don't take into consideration, combining effects when other chemicals are added into the garden mix according to THEIR directions, all of which degrades or combines into still other chemicals, many carcinogenic, none of those assessed before those misleading instructions are concocted. Indeed the labeling is vastly more for legal rather than safety concerns. It did not surprise me that you expressed a profound & misguided faith in labels which instruct that toxins be dumped in your immediate environment. It doesn't mean I disrespect you the way i would disrespect a Monsanto flack pretending to be a disinterested party as he obeys the company dictate to muddle every argument, but on another level its sometimes more annoying when reasonable people make unreasonable assertions. Really I was responding to your untrue statement that "another pest" (I assumed you meant in addition to the apple maggot that had just been discussed in the thread) that cannot be controlled organically was plum curculio. You were dead wrong but i weary sometimes of correcting that sort of misinformation & so posted about your love of cowshit instead, thinking myself amusing rather than bad for it. Both those orchard pests are now pretty easily controlled organically. That plum curulio was once believed to have no effective organic control was disproven a good five years ago, when the final barriers hampering organic orchards in the Northeast fell away (Pacific Nrthwest organic orcharders didn't want the sudden competition & were sorry the Northeasterners wised up). Surround is approved as an organic pesticide. The effective ingredient of Surround is natural clay kaolin (hard to call it "active" ingredient since it is inert). Field trials overseen by Drs. Michael Glenn & Gary Puterka of the USDA found that orchards that had been experiencing 20 to 30 percent damage from plum curculio dropped to .5 to 1% damage with application of Surround. (It could well be that with broader organic principles in place, even Surround would not be necessary, but commercial orchards are by their nature not mixed-species environments so it's hard to achieve the prophelactic balance that is easier in a more complex community of gardened plants). Now the chemical industry would prefer it if what you said were true, & would want it noted that Surround does not kill anything at all, but only suppresses sundry pests up to & including plum curculio. From a growers point of view there really is no difference, except the well-protected organic crop has a higher value than a crop from the chemical-dependent. If I get a wee bit peevish about flat assertions that have no truth & which misrepresent organic principles as weak or tepid & encouraging pests, it's cuz it's annoying to see presumedly reasonable individuals insisting on such falsehoods then advovating the use of harmful toxins as completely safe safety when used responsibility & mistakenly insisting there is no choice about it. Invariably, as in the two examples presented in this thread by yourself & Sherwin, there is always a choice. The decision to further toxify the environment cannot possibly be arrived at responsibly when the first piece of "reasoning" is that pests can't be organically controlled so there is no choice. Frequently the organic choice is objectively the more effective choice, & yet advocates of toxicity don't want the documentation of such facts, won't read the science, & will rarely correct their story. -paghat the ratgirl -- Get your Paghat the Ratgirl T-Shirt he http://www.paghat.com/giftshop.html "In every country and in every age, the priest has been hostile to liberty.

I have noticed several things in paghat's replies on this topic.
For one, she talks about her experiences with Elm Trees and Roses. Does she grow apples or plums? She quotes a lot about this study and that, but what direct experience does she have herself. For every reference she quotes about organic methods, I can find an equal number of those advocating spraying with chemicals. Paghat also fails to make a distinction between commercial orchards and home orchards. A commercial orchard cannot closely monitor the effects of hundreds of trees, and therefore takes a 'blanket' approach to control. The more sophisticated of these orchards will put out traps to determine what type of insect is attacking, and when best to treat for it. A home orchardist can be more selective and can do a better job of monitoring pest damage. Although I concentrated on insects, fungus problems are also something which can ruin your crop, and even kill your fruit trees. I have not found any organic fungicides that work effectively, and I have tried quite a few, like Rhotenone. Lastly, Paghat thinks she can win this argument with documentation. I have examined some of this material and have found no substantial evidence that organic methods can control the problems already mentioned. The growers in my Fruit Club who use organic methods are limited to two choices. Accepting a goodly amount of ruined fruit and/or limiting themselves to certain disease resistant varieties, which only takes care of fungus, but not insect problems. I work too hard maintaining my trees to see the fruits of my labor thrown away by insect infestation. Not to mention the trees that are lost by insects like borers. I consider the state of the art, that organic methods can be used to cut down on problems, but have not quite reached the point where they alone can do the complete job. Unfortunately, the new varieties of apples that are disease resistant, although improving, have not equaled the taste and flavor of other apples. If Paghat can grow fruit without spraying, she is certainly a most fortunate person.

I know because I have been growing fruit for over 20 years and have tried all the organic sprays and controls. The best method of apple maggot control is the use visual traps for the adult flies before they lay their eggs, ADDING a natural host odor with the trap [Rull et al, Entomologia Experimentalis et Applicata, January 2005 -- note the date, it is very recent research that has shown the effectiveness of non-sparying techniques]. While it has become a cliche that no organic spray is half as effective as highly toxic organophosphate type pesticides, it is now well established that methods other than spraying can be completely effective. Because crop value is higher for organic crops, there is no net gain by using potent toxins [Reissig, Journal of Economic Entomology, Oct 2003]. Once a grower realizes spraying is not the best or primary method (organic or otherwise) comparisons of organic vs non-organic spraying becomes moot. But fact is, the 2001-2002 Cornell study headed by Terence Robinson of organic apple techniques (tested in New York & Ontario) discovered control of apple maggot with organically approved Surround was completely effective. So the popular cliche that only harmful organophosphate insecticides work is now conclusively known to be false. Comparative analysis in Quebec conducted over a ten year period found that completely unsprayed apple orchards had infestation rates ranging from 0 to 4.1% [Vincent & Mailloux, Annales de la Societe Entomolique de France, 1988; Vincent & Roy, Acta Entomologica et Phytopathologica Hungarica, 1992]. Unless losses exceed 5% it is counterproductive & unnecessary to even consider chemical spraying. Any gains from using toxins are more than offset by the extra costs of chemicals plus the lowered value of non-organic crops. If apples were not permitted to rot on the ground, the orchard would not have any apple maggot pupae overwintering in the soil, & the only threat of infestation is from adult flies coming from outside the orchard. Often removal of elderly apple trees & hawthorns from surrounding properties is the only control required. In all cases, by the time eggs are laid, the maggots are impervious to toxins; so stopping the adult flies at the periphery becomes the goal. Even growers who do use pesticides often use them exclusively OFF the periphery of the orchards & NOT on the trees themselves [Thimble & Solmae in Crop Protection, 1997] since a clean orchard has no emerging flies inside the periphery. Others who use insecticides do so only in the scent-baited sticky-traps again to keep poisons off the crop. The milestone research of the late Ron Prokopy (who died last year) with even just unscented traps triggered a revolution in organic apple growing that left the chemical-dependent growers in the pesticidal dust. Chemical dependency bred chemical dependency, & here in Washington as the chemical-dependent growers went bankrupt one after another, organic growers flourish. The more recent (even just within the last four years) scent-baiting of the Prokopy traps has has made trap strategies so extremely effective that organic apple growers have either fewer or no more losses than lazier less knowledgeable growers who spray & thus produce a less valuable harvest. Effectiveness of Prokopy sticky traps PLUS host scent is today the preferred method of apple maggot control, preserving the added value of organic crops. The big reason some orchards would still spray today is because they are producing pig-feed apples & it is too labor intensive both to maintain bait-scented traps & to clean up fallen apples, when in any case the crop will remain poorly valued. In Washington state the primary threat to fully organic apple orchards are infestations bleeding over from trees grown in the back yards of homeowners who do not know to control apple maggot with scented stickytraps, & who let fallen apples remain on the ground so that the next year's infestation developes. Sponsored programs to involve morons, I mean backyard amateurs, in the use of scented traps, even providing the traps for free, & educating the amateurs on the necessity of immediately cleaning apples off the ground before the worms crawl into the ground to pupate, is far more effective than trundling out increasing numbers of increasingly toxic chemicals & pretending there is no way around them -- though certainly the chemical industry's propoganda encourages that misguided belief. Only the chemical companies themselves continue promulgate the so-called "integrated" system of traps plus toxic spraying. -paghat the ratgirl I still utilize a combination of organic methods, like trapping insects on sticky balls and dormant oil. I have yet to find an organic method to effectively control apple maggot, for starters. Like any other technique, spraying can be done correctly, or not. You should not spray insecticide (fungicide is ok) when your trees are in blossom. That indeed will kill any bees around. You should not locate your trees near your vegetable garden. You should spray on near windless days, so that it stays confined to your orchard area. You should wear protective gear, including breathing masks, and not spray when kids or pets are around. This all makes it sound a bit dangerous, but so is getting on the freeway with all the idiot drivers. If you want the majority of your fruit to be clean, you probably have to spray in your location, especially since you have already noticed what sounds like heavy insect damage. I would recommend a general orchard spray (Bonide makes one, for example). It contains a combination of insecticides and fungicides. These types of sprays are meant to cover most orchard problems, but if you have a more serious situation, you may have to go to a specific spray which targets it. Try the orchard spray first, and then see how it goes. You may have had a better reception if you had gone to rec.gardens.edible, where there seems to be more people growing fruit.

I have religiously cleaned all fruit from my backyard. I tried all these traps,
and still the insects have come. There are no other fruit trees in my neighborhood to account for this infestation. The traps help somewhat, but don't do a complete job. I don't know why paghat keeps talking about commercial orchards. We are home gardeners, who grow things in our backyards, on a much smaller scale. Insect damage is more distributed in a large commercial orchard, so if a small percentage of the trees get hit, there are many others to take up the slack. That is not the case of a home orchard, where you have only a handful of trees, usually one tree per variety. If one of those trees gets hit, you have lost that variety of fruit for the season. You should also mention that these traps are very expensive, especially the pheromones. I have not noticed any significant retardation of insect attacks using them, so I will not rely solely on their effectiveness. paghat wrote: In article , sherwindu wrote: Now that we have heard from all the 'organics', lets hear the other side of the story.
