Tomato leaf spots in 1942 and '43 caused low yields and poor quality of fruit in many eastern South Dakota gardens. Successful control of these diseases must be based on preventing early infection of the plants and the spread of the organisms which cause them. This circular describes briefly the two leaf spot diseases of tomatoes common in South Dakota. Control measures for each are listed on page 7.
