microfungus
I just hit them with a couple shots of Avid but I need to buy some more
(just noticed some damage on the phals upstairs too). I think that's around $100 for 8 oz. I got a little bit (1/2oz.?) in a group order from another plant society I was in last year. Some of the miticides run $200-$300 a bottle. I think I have some Pentac that a friend gave me around here somewhere. I think the Pentac knocked down the population last year. I really need to get better about spraying several applications to make sure I get all of them. I can see spider mites on plants without a magnifying glass. I don't really see webs on the catasetums but the bugs look like the spider mites I've seen on some of our other houseplants. I guess if I did look at them with a magnifier then maybe I could look up some mite pics on the web and verify what they are. If Kenni has a recommendation for current miticides I'd like to hear it. -danny "Diana Kulaga" wrote in message ... Danny, Which miticide do you use? Last spring, I noticed flower and leaf damage on our Phals, and also fine spider webs. Couldn't see anything, even with a mag glass, and a "white paper test" was inconclusive. I assumed spider mites. (I know - assumptions. But what else can one do?) What I used was 2 Tb. dish soap + 2 Tb. cooking oil/gal water as a drench, twice. Seemed to work, but I'm seeing some patches again. Kenni mentioned a heavy duty miticide which kills the up and comers as well as the adults. Very pricey. Kenni, are you out there? Diana "danny" wrote in message .. . I get yellow chlorosis on quite a few of my thinner-leaved phals, without any other symptoms. Anyone know what may cause that? It doesn't seem to seriously harm the plant. I also get silvery areas with collapsing tissue on the bottoms and bases of leaves of all types of phals, which tends to stop progressing if I hit them with miticides, so I assume that is just mite damage (which mites hit the phals? I can't see them. They must be a lot smaller than the spider mites on the catasetums.) -danny |
