                    Early blight is an important worldwide  disease of tomato that farmers must have  frequent spray chemicals to control  it. One way to reduce the use of  pesticides, costs of production and the risk of environmental pollution, spraying based on forecasting of TOMCAST system, which is based on the time of wet leaves and temperature during tomato growing season in each region, predict disease severity , and determine suitable  time of spraying. Application this system, in some countries considerably reduced pesticides usage on tomato. This system predict time of spraying when needed and has maximum effect. By using this forecasting method in Iran, can reduce  pesticides usage on this freshly  consume fruit, efficiency of using pesticides, and increase yield.
