Copper Sulfate fungicide, I use Bonide brand. They even use it on organic vegetables. https://www.google.com/search?client=opera&hs=YEe&ei=duINXca-GeqO0gL8uZCwDg&q=Bonide+copper+sulfate&oq=Bonide+copper+sulfate&gs_l=psy-ab.12..0.43804.46422..57979...0.0..0.173.623.5j2......0....1..gws-wiz.......0i71j35i304i39j0i13j0i7i30j0i8i7i30.5iaECi6kpOo
Copper sulfate can cause severe eye irritation. Eating large amounts of copper sulfate can lead to nausea, vomiting, and damage to body tissues, blood cells, the liver, and kidneys. With extreme exposures, shock and death can occur. ... Diarrhea and vomit may have a green to blue color.
Hi Jeanne, I use Bonide brand fungicide also.
spray a mixture 70% cows milk(any kind as long as it is not lactose free) and 30% water on them, all over-under all leaves-ontop-all stems/stalks in early morning or late eve. just not in full sun.
Many thanks, I will try it right away.
