My 3 big rabbiteyes have a pretty bad case of Powdery Mildew. Most of the mildew is on the bottom of the leaves and the plants are still producing berries. Im a couple weeks away from them being done fruiting. My plan is wait untill harvest is over and I do the summer prunning on these plants before spraying with some kind of fungicide. Does this sound like a good route to go??? I havent had to spray any of my plants with anything to this point but Im afraid if I dont the plants wont form fruit buds like they should if the leaves fall to early. Any thoughts and suggestions would be appreciated!
