eagle 20 is the only real cure for PM.

spray once or twice in veg and you will never see pm again.

It's not organic, but it's immobile (so it wont get in your buds if you only use in veg). It is used in the fruit industry. If I use in veg, I never see the PM in flower.

I fought that crap for 6 months and tried every organic method I could find (neem,serenade,baking soda...) and had environmental controls down, once that crap is in your room... there is no other great way to get it out. A sulfer burner will help, and it's good to use to change the surface environment, but the PM is IN the plant tissue.

you can find small (1 oz) containers on ebay. the $60 container has enough for 2 lifetimes. It takes something like 1/4 teaspoon per gallon, IIRC.

best of luck
copobo Reviewed by copobo on . Powdery Mildew - Washington peeps Any of you Washingtonians having difficulty with powdery mildew lately? I hear a lot of folks are. Only appears in my flower room so far and I'm hitting it with a baking soda solution to try and at least retard it. Also have about 1/2 the room nearly ready to chop so I'm going to accelerate by a few days as much as I hate to. Any other suggestions? Anyone using a sulphur burner? Peace, Farmer Rich Rating: 5
