Abstract
The Tom-Cast disease forecasting model, based on leaf wetness and temperature, predicted that in a dry season fungicide sprays were unnecessary for control of early blight, Septoria leaf spot and anthracnose fruit rot, in processing tomato crops.
Up to 9 applications of fungicide are made per season to Australian processing tomato crops, with most growers applying 3 to 4 sprays.
The model was evaluated in crops at three locations over a two-year period by comparison with the growers normal spray application practices.
The adoption of the Tom-Cast model by processing tomato growers could save the Australian processing tomato industry an estimated $150,000 to $200,000 a year in fungicide costs.
