It may seem odd to think that fungicides in a dry year could impact yields since they are designed primarily to control fungal diseases, however many higher end fungicides have a level of crop stress mitigation as well. Under stress, plants will produce the larger amounts of hormone ethylene which is the same hormone that leads to fruit ripening in plants. Fungicides that contain additional plant health components such as Veltyma, Revytek, and Miravis Neo can help reduce this stress hormone and therefore assist the plant when dealing with in season stress.
