Diseases like powdery mildew and black mold impact tomato crops by destroying leaf tissue and reducing energy that could otherwise be used in fruit development.

In addition, the loss of foliage leaves fruit more susceptible to sun damage. Fungicide applications can help control disease and can be applied preventatively or early on in the infection.

According to University of California Agriculture and Natural Resources, tomato crops can have black mold 4 to 5 days after a period of heavy rain and humidity. Tomatoes should be harvested once they have ripened because delay can increase the likelihood of black mold.

A fungicide treatment, Quadris Top®  fungicide, should be used to control disease and is especially important in this rainy year. Through a combination of azoxystrobin and difenoconazole, Quadris Top helps control key tomato diseases.
