Disease Control

All fungicides available for disease controls are effective only as contact treatments. Therefore, it is crucial that they be applied prior to, or at the first sign of a fungal disease.

Starting a scheduled application of fungicides on plants susceptible to mildews etc. will go a long way in preventing diseases from even starting.  Most fungicides should be applied starting June 15 in our area, and applied again every 7-10 days throughout June and July.  If your plant is already covered in mildew, these products will only serve to prevent the disease from becoming much worse.
