| Abstract: | Effects of fungicides carbendazol and tebuconazole on the control efficiency of maize stalk rot and maize yield were investigated by field experiment of chemigation under plastic film in the sandstorm semi-arid area of western Liaoning province.The results showed that the control efficacy of stem base rot was above 54%.The control efficacy of tebuconazole 25%WP at 140 g/667 m^2 of chemigation was up to 72.60%,and the average yield reached to 948.94 kg/667 m^2,with the yield increase rate of 59.92%significantly higher than that of inoculation without treatment.The control efficacies and the average yields of carbendazim 50%WP at 60 g/667 m^2 and 120 g/667 m^2 of chemigation were 54.79%and 67.99%,755.24 kg/667 m^2 and 810.43 kg/667 m^2,respectively.The ear length,ear diameter and 100-kernel weight of maize were significantly different among the different fungicides treatments.Chemigation with carbendazim can increase the income and benefit by￥218.68 per 667 m^2 each year.Chemigation with tebuconazole and carbendazim can effectively control maize stalk rot and significantly increase the maize yield and production efficiency. |
