Thanks, Freckles Yes, enough soapy water could be dangerous, but that's not what we are talking about. Why don't you look up the MSDS on the products that you suggest and see what their environmental impact is? When the oil runs out, top soil will be the only thing between us and starvation. Try to save a bit of it.

"Freckles" wrote: I use Bayer's Rose & Flower Care http://pmep.cce.cornell.edu/profiles...yphosate/disul foton-ext.html ACUTE TOXICITY Disulfoton is very highly toxic to all mammals by all routes of exposure. It is labeled with a DANGER signal word. Whether absorbed through the skin, ingested, or inhaled, early symptoms in humans may include blurred vision, fatigue, headache, dizziness, sweating, tearing, and salivation. Symptoms occurring at high doses include defecation, urination, fluid accumulation in the lungs, convulsions, or coma. Death can occur if high enough doses lead to stoppage of respiratory muscles and/or constriction of the windpipes. Ingestion of high doses can lead to rapid onset of effects on the stomach while symptoms resulting from skin exposure may be delayed for up to 12 hours. Complete recovery from acute poisoning takes at least one week, but complete restoration of the blood to normal enzyme (cholinestrase) levels may take up to three months (9). The oral LD50 ranges from 6.2 to 12.5 mg/kg in male rats and from 1.9 to 2.5 mg/kg in female rats (12, 10). Weanling male rats have an oral LD50 of 5.4 mg/kg (10, 5). The dermal LD50 is 3.6 mg/kg for female rats and 15.9 mg/kg for male rats (4, 10). The inhalation LC50 for one hour is 180 ppb for male rats, and 90 ug/L for female rats (3). CHRONIC TOXICITY Disulfoton is rapidly absorbed through the skin. This chemical inhibits cholinesterase, and, as a result, may affect the eyes, respiratory system, and central nervous system (9). Continual daily absorption may cause flu-like symptoms, loss of appetite, weakness, and uneasiness. While repeated exposure to disulfoton may inhibit the cholinesterase enzyme and thus interfere with the nervous system, 30-day human exposures have not resulted in significant enzyme inhibition (10). Workers chronically exposed to organo-phosphates, of which disulfoton is a member, have developed irritability, delayed reaction times, anxiety, slowness of thinking, and memory defects (9). Chronic exposure of workers may also lead to cataracts. Rats have survived daily doses of 0.5 mg/kg/day for 90 days. Some studies have shown that rats can acquire a tolerance for the chemical, so they are able to adjust to the lower cholinesterase levels resulting from chronic lower level exposures (8). Reproductive Effects In a long-term reproduction study, 98.5% pure disulfoton was fed at doses ranging from 0.05 to 0.5 mg/kg/day to both male and female albino rats. At the high dose, the number of animals per litter was reduced by 21% in the first and third generations and a 10 to 25% lower pregnancy rate was noted. Some third-generation litters whose parents were exposed to this dose, developed fatty deposits and swelling in their livers. Exposed adults and litters had a 60% to 70% inhibition of red blood cell cholinesterase (10). This suggests that long-term exposures to high doses of disulfoton may cause reproductive effects in humans. Teratogenic Effects In one study, pregnant rats were given disulfoton (98.2% pure) at doses ranging from 0.1 to 1.0 mg/kg/day through a stomach tube during the sensitive period of gestation. Cholinesterase activity was decreased. In the fetuses, no developmental defects were seen except at high doses, where incomplete bone development was noted (4, 10). In another study, rabbits were given disulfoton (97.3% pure) during the sensitive period. At the higher doses (1.5 and 2.0 mg/kg/day), the mothers experienced tremors, incoordination, and death, while fetal growth was not affected (10). These studies indicate that disulfoton is very unlikely to cause birth defects in humans. ECOLOGICAL EFFECTS Disulfoton-containing products are highly toxic to cold and warm fish, crab, shrimp, birds, and other wildlife (7, 8). The acute dietary LC50 for disulfoton in mallard ducks is 692 mg/kg, and 544 mg/kg in quail. The EPA has stated that use of disulfoton on certain crops may pose a risk to some aquatic and terrestrial endangered species (17). ------ You people don't have a clue as to what your doing and your mindlessness affects everyone. -- - Billy "For the first time in the history of the world, every human being is now subjected to contact with dangerous chemicals, from the moment of conception until death." - Rachel Carson http://www.youtube.com/watch?v=WI29wVQN8Go http://www.haaretz.com/hasen/spages/1072040.html |

I've heard systemic pesticides can be very dangerous. I've tried several different sprays and am not satisfied with the results. Can anyone recommend a brand of systemic pesticide that is not so dangerous to humans and pets? Thanks, Freckles I use Bayer's Rose & Flower Care, which combines fertilizer and systemic insecticide in a dry granular form. Although I feed my roses every month from March through October, I use this product only every-other month to get excellent results. In the alternating months, I feed my roses with ammonium sulfate. You might instead consider using Bayer's 12 Month Tree & Shrub Insect Control, which is a systemic applied as a soil drench. I used this very successfully to control leaf miners on citrus. It is considered non-toxic to vertebrates (humans, other mammals, birds, reptiles, fish, etc) and is thus safe on edibles. It controls such rose pests as aphid and white fly. I haven't tried this on my own roses. You might call your local agricultural extension to ask about using it. I will be calling my county's agricultural extension when I replace my peach tree to determine if it will control flat-headed bark borers since Lindane is no longer available. NOTE: 12 Month Tree & Shrub Insect Control can be quite expensive; it cost over $20 to give one treatment each to a dwarf lemon and a dwarf orange. -- David E. Ross Climate: California Mediterranean Sunset Zone: 21 -- interior Santa Monica Mountains with some ocean influence (USDA 10a, very close to Sunset Zone 19) Gardening diary at http://www.rossde.com/garden/diary Thanks for the information. I just order some Bayer insect control plus fertilizer plant spikes which seem to be just what I want. I've been watching the organic vs. chemical debate for years. I have tried to go organic, but with very limited success. The plant stakes I've ordered seem safe enough and they are not too expensive. Much of the organic materials I've used were a lot more expensive than chemicals and in many cases I needed to use much more of them to get the same results I could have gotten with a few chemicals. If my grand dad had tried to go organic on our farm, we would have starved. Freckles Too many people confuse "organic" with "natural". For my comments on this, see my http://www.rossde.com/garden/garden_organic.html. My own gardening practices involve a mix of organic methods and non-organic methods. I produce my own compost (actually, a leaf mold), which I add to my potting mix to inject the mix with the kinds of soil bacteria that are needed to convert nutrients into forms that plant roots can absorb. I use bone meal and blood meal in my potting mix for house plants. I generally wait for ladybugs to deal with aphids. (I don't have to buy and disperse them; they come naturally.) To combat brown snails (Helix aspersa, also known as Cantareus aspersus), I can't use poisonous snail bait because my tortoise would then eat the still toxic dead snails. Instead, I use carnivorous decollate snails (Rumina decollata), which eat the eggs and young of the brown snails. I also wrap copper wire around flower pots containing plants that are especially attractive to brown snails. On the other hand, I feed my roses, citrus, and other plants with chemical fertilizers. After pruning them, I spray my peach, roses, and grapes with a mix of dormant oil and copper sulfate. Newly planted flowering shrubs have super-phosphate dug into the soil below their root balls. Yes, I do use systemic insecticides on my roses and citrus and Roundup on thistles sprouting on my hill. As for my leaf mold, I accelerate its decomposition by adding urea (50-0-0) to the pile. Am I an environmental rogue? I don't think so. Birds and squirrels seem to enjoy my garden. Raccoons steal my grapes. Many, many bees constantly visit my flowers. And Cleopatra -- an endangered California desert tortoise (Gopherus agassizii) -- has happily grazed in my back yard since 1977. (Before you consider reporting me for having a contraband tortoise, Cleopatra is already registered with the California Department of Fish and Game; she is legal.) -- - Billy "For the first time in the history of the world, every human being is now subjected to contact with dangerous chemicals, from the moment of conception until death." - Rachel Carson http://www.youtube.com/watch?v=WI29wVQN8Go http://www.haaretz.com/hasen/spages/1072040.html |

Bayer.....patoooie and effem. Baby and bee killing bastids. I worked for those effers for four years in the late seventies and early eighties, (and am still ashamed to admit to being a Magic Christian during that period) and they dealt death. Worse now. I've been watching the organic vs. chemical debate for years. I have tried to go organic, but with very limited success. Then your processes and understanding were/are flawed. The plant stakes I've ordered seem safe enough and they are not too expensive. Much of the organic materials I've used were a lot more expensive than chemicals and in many cases I needed to use much more of them to get the same results I could have gotten with a few chemicals. Less more, less more....."Better Things for Better Living...Through Chemistry." DuPont (and dow and monsatano and on and on) You don't just substitute organic "stuff" for deadly stuff to achieve health and balance. Your understanding of soil health and organic is lacking. If my grand dad had tried to go organic on our farm, we would have starved. FKN bullshit. You don't understand organic and/or soil health. How old are you? When was your grand-dad "farming"? Educate yourself. Make a commitment to planetary health and view your prcesses in that light. I'm fkn sick of excuses like, I grow stuff that shouldn't be grown here, so I gotta use poison, or it's too much work and expense to grow safe and healthy food. Gawd, the list goes on and on and on......ad nauseum. What the hell is wrong with all you chemical-head ignoramuses? Charlie Another ignorant fanatic heard from! If it were not for those dangerous chemicals, as you like to call them, there would be even more millions of people starving. than there are now. Most, if not all, of the medicines used to combat illnesses and ailments are dangerous, but we still take them. I guess you refrain from taking such medicines because of their harm to the environment. Ha Maybe you think organic farmers can supply enough food to feed the world. How ignorant! Besides, this is a gardening newsgroup, not an organic only group. If you don't like what you read here, go elsewhere and stick your head in the sand there. In other words get lost asshole! |
