Grasshoppers are an occasional pest in Iowa farms and gardens. The number of grasshoppers varies greatly from year to year and from place to place. This appears to be one of the years when at least some growers and gardeners are going to see more than the usual number.
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.
A recent inquiry from an Extension and Outreach colleague about timing of preventive treatments for the emerald ash borer (EAB) was insightful. This note is written to help direct types of treatments to the seasons they are most appropriate.
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.
