|What product can I put on my table grape plants to prevent mildew from ruining the grapes? They are growing in full son on a pergola and the grapes hang down. Red Flame seedless, & Black seedless grapes are the types. This is the 2nd year I've lost the crop. I water two times per week.|
|How disappointing for you! Several fungicides, including Abound, Captan, Copper compounds, (fixed coppers and Bordeaux mixture), Mancozeb, Ridomil/MZ, Ridomil/Copper, Sovran, and Ziram are effective against mildew
Repeat sprays may be needed and sprays should start in mid-summer to protect the vines and the fruit. Always follow the label directions for best results.
