Denny was just taking a break when I read your post.Been at it for several hours giving my tomatoes a copper bath for blight protection.This is about as organic as I get with 150+ plants to do but really works and is quite beneficial when the hot humid days arrive.
Will this work after planting (spray) or is it too late to combat blight after it happens?
thanks
It's better countermeasures to do it before planting before onset of the blight and will only be effective if you can spray on the under side of the foliage as well.Tank spraying will work if you can do it at planting but like I said get the underside well drenched.The tub in the pic holds 18 gal.I use one and a half canisters of the copper and add three tablespoons of dish soap for tack.
