Last year we would find brown spots on our scuppernong grapes and then in a day or so they would fall off. The only pest we would see was a wasp and there were several of them hitting the grapes. What are my options to prevent it this year? I hate to use chemicals!

is your grape in a greenhouse? if so then keep the humidity a little higher. I think the wasps have nothing to do with the fruit drop.
