Interactive Tools and Models: Tomato Powdery Mildew Spray Forecast

This spray forecast model for tomato powdery mildew (TomatoPM) was tested for two years in 10 fresh market and processing tomato fields in the northern San Joaquin Valley and southern Sacramento Valley of California.

If using TomatoPM in new areas, you are encouraged to test it for one or more seasons under local conditions. Monitor fields closely for disease while testing the model.
