Septoria leaf spot and early blight are common foliar diseases of tomatoes in home gardens. Fungal diseases overwinter on plant debris in the soil. Fungal spores are splashed onto plant foliage by raindrops or splashing water and invade the plant tissue when leaf surfaces are wet. Rainy weather in spring and early summer favors development of foliar diseases on tomatoes.

Insecticide product labels state that there are two windows for preventive treatments when applied to the soil or externally to the trunk of the tree: Spring and Fall. Iowa State University Extension and Outreach publication PM2084 currently includes both windows, in keeping with the product labels. Trunk injections can be done in a wider window (May through September 1) when the tree has a full crown and there is good soil moisture.
