摘要： Grey mold disease caused by Botrytis cinerea Pers. ex Fr. is a severe threat to tomato (Lycopersicon esculentum) yield in field and greenhouse in many countries worldwide. In this study, 12 fungicides agents were selected to determine their inhibiting effects on mycelium growth of Botrytis cinerea Pers ex.Fr. and 4 of them with better effects were used to further test the disease control in field. Our results showed that 70% thiophonate-methyl (WP), 50% methyl sulfur bacteria-spirit shine (WP), 50% iprodione (WP) and 99% wichol (TC) exhibited stronger inhibition of the mycelial growth at EC50 value<100 mg/L. In addition, 50% cycloamines (WG) and 40% iminoctadine (WP) provided partial inhibition at EC50>10000 mg/L. But 80% carbendazim (WP) and 80% Phenyl ether Jiahuan azole (WG) provided minimal inhibition at EC50>10000 mg/L. Furthermore, the field test showed that 70% thiophonate-methyl (WP), 50% methyl sulfur fungal spirit shine (WP), 50% iprodione (WP) and 99% wichol (TC) provided stronger control effects than those of the boscalid, and these agents could be used in grey mound disease control in practical tomato production.
