Description

Ridomil 2E® fungicide received a federal label in 1991 for control of seedling diseases of alfalfa caused by Pythium and Phytophthora fungi. Pythium fungi are widespread in Kentucky soils but can be controlled with Apron® seed treatment. Phytophthora is less common in Kentucky soils. Where present, Phytophthora can usually be controlled with a combination of resistant varieties and Apron seed treatment. Occasionally, yield increases may be observed using Ridomil in fields highly infested with Phytophthora. However, broadcast applications of Ridomil at seeding are not recommended for most alfalfa fields in Kentucky.
