Thanks a lot mam I'm farmar we grow grapes calcium carbonate and copper sulfate is really works better that other fungicide.. it can't sprayed during pollinating season because Flower drop other than its effective.. downy mildew is difficult to handle because it spreads in all seasons but powerdy mildew only in raining seasons and fog seasons however it can be controlled by using contact fungicide but downy mildew requires systemic fungicide that is economic bit costly thanks mam learnt much
