Just wrote this in a PM to another grower. Since I spent some time on it thought I'd repeat it here. Question was, "Uncle Ben, have you ever had PM problems and if so, how did you control them?"

Never on cannabis but I do spray, rarely, PM control products on squash or cukes. I also have a broad spectrum spray program for grapes which includes PM control. Based on the 2014 Spray guide for Texas grape growers here are the most effective, food safe, products recommended for PM:
Pristine - a topical and systemic 'silver bullet', but very expensive. My fave. I mix it with Rally, see below.
Myclobutanil - that is the active ingredient found under many names. Cheap and another one of those "silver bullets". Rally 40WSP is a commercial product I use. Price may be high but a little goes a lonnnnnnnng way as it contains 40% of the AI, active ingredient. Hardware stores will have mcylo. It will also control black rot, leaf blight and many other diseases. If you do any other type of gardening or have turf problems, this one is the one to have on hand. The over the counter products are a rip off, like this one at only .78% of the AI. http://www.ebay.com/itm/SCHULTZ-FUNGICIDE-PLUS-CONCENTRATE-Disease-Plus-Insect-Control-16-fl-oz-Bottle-/190947134508?pt=LH_DefaultDomain_0&hash=item2c75560c2c
This is THE cheapest way to go at 20% AI (active ingredient) - http://www.ebay.com/itm/Eagle-20EW-Fungicide-1-Pint-/231008032597?pt=LH_DefaultDomain_0&hash=item35c926d755 Post harvest interval is 14 days. Only 1.5 ml/gal.....include a surfactant. (That calculation is based on a recommended rate of 5 oz/100 gals.)
Quinoxyfen
Sulfur, although I don't think your buds will smell/taste so good.
