Mealy Bug Treatment Question?
Orthene usually works for mealies, but these days you must read the labels.
The active ingredient is acephate [also sold as Isotox and under other brand names]. You need one that lists acephate as 75% in strength [in the concentrate]. It has been coming out in more dilute concentrations, lately, and these are not only ineffective, they are likely to create resistant strains. Good growing, -- Kenni Judd Juno Beach Orchids http://www.jborchids.com "sandra" wrote in message oups.com... Hello, I've recently noticed that after I water a few mealy bugs come to the surface of my orchids... What should I do to get rid of them. I've heard of X-clude and Orthene, but I would really appreciate some personal input Thanks, Sandra |

I, too, wondered if it might be what we call "fungus gnats," or even one of
the odd-looking ants, but either way the Orthene should work. If they are seriously nested in the medium, it would be a good idea to soak them in a dishpan of water [water level slightly higher than the pots] before spraying. Kenni "Larry" wrote in message . .. Sounds more like gnats? Larry "Steve" wrote in message ... Wait a minute Kenni. Your advice is good if Sandra has mealies but I question if she really does. If Sandra only sees mealies when they come to the surface after watering, what do you think? Sandra, do you have mealy bugs on the leaves of your plants too? If not, are you really sure of what they are? Steve Kenni Judd wrote: Orthene usually works for mealies, but these days you must read the labels.

Ewww, fungust gnats.....
What causes them, what should I do water less? The potting medium doesn't look broken down, and a lot of my phals are spiking should I repot? These little animals are sort of tiny, my sister showed me a photo of some mealy bugs yesterday, so they can't be it, and none of them are on the leaves either. As I said, there's just a few in the potting medium, and they come above and rest on the aerial roots each time I water & feed. I was wondering as well, I have a phal bellina, a few days ago I was looking at the roots and a few of them appear to be turning a brownish color. It can't be the potting medium because I took the plant out and checked it, there's nothing breaking down. Is it okay if I water with dilluted physan 20 once a month to sort of ward off any potential for rot in the medium of my phal bellina, I read somewhere that phal.bellina is a lot more susceptible to root rot....so should this help a little... -Sandra Kenni Judd wrote: I, too, wondered if it might be what we call "fungus gnats," or even one of the odd-looking ants, but either way the Orthene should work.

Ewww, fungust gnats..... What causes them, what should I do water less? Momma fungus gnats... *grin* Fungus gnats are reasonably harmless, but are a sign of decomposition in your potting mix. A little decomposition is probably a good thing (a lot is obviously not). Fungus gnats look a lot like fruit flies. I have a fungus gnat flying around my office right now. Driving me nuts... If you want something harmless, get some Gnatrol, which is a variety of Bacillus israeliensis (I think). They give the little gnat larvae serious tummy aches. They used to make a reasonable hobby size of that, now you might have to buy a gallon. Failing finding a suitable supply of gnatrol, you could just use sticky traps. A yellow piece of cardstock covered with some rubber cement works, or you can buy traps already pre-stickied. I see them at the hydroponics store. The gnats like bright colors, and get stuck. Doesn't get them all, but keeps them down to a minimum. You can get yellow traps or blue traps. I think they are supposed to attract different bugs. Not a bad idea to have some around to monitor pest populations. The potting medium doesn't look broken down, and a lot of my phals are spiking should I repot? These little animals are sort of tiny, my sister showed me a photo of some mealy bugs yesterday, so they can't be it, and none of them are on the leaves either. See if you can find a picture of springtails on the internet. That is my guess. They are effectively harmless, but kind of gross. Like fungus gnats, they also thrive in decomposing potting mix. -- Rob's Rules: http://littlefrogfarm.com 1) There is always room for one more orchid 2) There is always room for two more orchids 2a) See rule 1 3) When one has insufficient credit to obtain more orchids, obtain more credit |

The knats are harmless just irritating!About the phal bellina I have found
this to be a tricky phal to get growing well,even to get growing at all!Give it warmth & humidity if this fails ditch it and don't by that type again. -- Thanks Keith,England,UK.

As I think you've seen by the variety of responses so far, we can't tell
exactly what you have, but all the likely suspects tend to like decomposing potting mix. So even if it doesn't look broken down to you, something may well be going on. Have you tried the "sniff test"? Decomposing media has a distinct "musty" smell compared to nice fresh stuff. There are lots of different approaches, as you've probably also seen. If the plants were mine: 1. If the phals are in short spike, not yet showing much in the way of buds and certainly not color, I would go ahead and repot -- discarding all old pots and mix. 2. If the buds are fat, I'd spray for the bugs and then enjoy the flowers, repotting after they finish blooming. I do not generally recommend preventive spraying of either fungicide or pesticide. If you do decide to use the Physan, please use at label strength -- using it too dilute can create resistant fungi just as spraying the watered-down acephate products creates resistant insects.

Well, I sniffed it and nothing..
It really doesn't smell like anything. -Sandra Kenni Judd wrote: As I think you've seen by the variety of responses so far, we can't tell exactly what you have, but all the likely suspects tend to like decomposing potting mix.
