The effect of spraying with the fungicide Curzate M 72.5 WP on the incidence of symptoms caused by infection with the Tomato spotted wilt virus in tomato cultivars: Potentat and Beta, was studied. Only at the cultivar Potentat a temporary reduction in number of TSWV infected plants was observed. This transient effect disappeared in the 7th week of experimentation, and was most probably caused by the repellent action of the applied fungicide.
