Dear friends. Some months ago I posted a situation asking about the best insecticide for killing Mealy. Majority agreed in Orthene. Currently, I have Orthene in my hands. It has a concentration of 97.4 % (powder). Use directions explains that for orchids it must be diluted 8 Oz by 100 gallons of water. I have calculated the necessary powder quantity for one gallon, an it resulted in 0.227 gr x gallon.
My first question: Is apropiate to use it in my orchids with such concentration??
Second question: Is fine calculation I did?
Thank you very much for your help!!!!!
