Terpz, what is your application rate with the Azatrol? I take it you have come to have success with this method? You would definitely be at a greater risk bringing in outside soil to your garden. Your post gives me hope! I found Qt of Azatrol on amazon for $78. 32oz mixes to how many gal? I already use DE I swear by that stuff, magic IMO. I'm still in veg so plan on dusting them again with DE. Thanks for your post.
