Good seed coverage is essential because current small-grain seed treatments do not have a vapor action. Follow manufacturers’ application recommendations to assure proper treatment. No single seed treatment or combination of materials controls all diseases. Know which diseases you are trying to control before you select seed treatment materials.
The “ Fungicide Effectiveness as Seed Treatments for Cereal Diseases” table shows currently registered fungicides and general control information for commonly used small-grain seed treatments. Some seed treatments have planting-depth restrictions, and many have grazing restrictions. New products and product mixtures are coming on the market regularly. Be sure to check current labels for the latest use information.
