Late blight (tomato and cherry tomato), the first treatment should be performed as soon as a weather event in the shelter supports a downy mildew infection (long leaf wetness and stems). Equation@ Pro is applied at 10-day interval. However, this should be reduced to 7 days in case of mild and humid climate, leading to very short incubation periods and at high risk of infection. In situations of extreme pressure, renew the protection with another fungicide after 5 days.
