You absolutely do NOT want to use Eagle 20 in flower...ever!!!

There really is no way to eliminate it in flower...The best you can hope to do is limp by til harvest with sprays, then wash your bud in a hydrogen peroxide solution if the pm gets into flowers, which it most likely will.
Then next grow, get some Regalia and use it...It costs less than $2 a week to use on a tent-full of girls, and will not only protect them, but make them thrive. It will help now, but will not eliminate at this stage....nothing will...nothing that won't ruin your bud that is.
Regalia® Bioungicide delivers improved crop yield and harvest quality by stimulating a plant’s ability to fight diseases. Effectively control Powdery mildew.
