I have more patty pan squash developing (mold) than those that grow normally. I have a drip watering system throughout my garden that runs 3 times a week for about 20 minutes. How do I prevent this on my still growing plants?
For all fungal diseases I would reduce watering...particularly near the fruits. Also apply copper or a fungicide such as daconil (chlorothalonil) on a 7 day applicationn schedule. Could try placing fruits on a board to keep them high off the moist soil.
