Phytophthora crown and fruit rot of vegetable crops, caused by the oomycete Phytophthora capsici has the potential to cause significant yield losses in cucurbit, solanaceous, and legume crops worldwide. In Wisconsin, Phytophthora crown and fruit rot has been a sporadic disease in vegetable production for the past 20 years. In the previous 10 years, weather patterns were generally dry and the disease was limited to small parcels of susceptible crops throughout Wisconsin.
