The first late blight fungicide application is recommended once 18 DSVs accumulate from green row. Green row typically occurs around the first week in May in southern […]
Continue reading...5-23-14 Tomato Report – Click to Download Disease severity values (DSVs) for early blight, septoria leaf spot, and tomato anthracnose development are determined daily based on leaf wetness (due to rainfall, dew) and air temperature. On a daily basis DSV values can range from 0 to 4 where 0 = no chance for disease development […]
