I know there are many threads on this but I am in a very critical situation. Large outdoor plants being attacked by PM.. some have a couple weeks to go some seem 3 or 4 weeks out.. I used MilStop (Potassium Bicarbonate) a few weeks ago and it seemed to help a bit but the PM has returned with vengeance.. Please any advice.. Is diluted milk a good option for PM in flower? For potassium bicarbonate solution is an atomizer sprayer or sump pump with hose and sprayer nozzle better? For the diluted milk method?
I dont have the option of just pulling the plants.. I need to fix this asap..
Most plants it is showing on the shady side of the plant..
I was considering washing the plants down with plain water to wash off the pm before applying a treatment but I'm not sure if this would make the infection worse..
Should I turn off irrigation timers or reduce frequency to try to slow the spread?
Please any advice or tips from people who have had success defeating or at least holding PM back in flower would be much appreciated. Thanks in advance.
Is there something else that can be used successfully in flower to stop PM?
