Hello, I'm here to say I've given wrong information in the past. I've said before that I used my Orthene 75 SP for spider mites... Well, in a recent attack of these guys on my banana tree I've tried to kill them with repeated attacks of my sprayer. (I've use this before and it worked.) But guess what. They couldn't have gone away because of my spray. Here is why... Since I've done multiple applications and they are still there I decided to read the mixture book.. No where in there does it say "spider mites" so. There you go. Orthene 75 SP. is not for spider mites. Although excellent for Thripes, Scale, and other bugs.
