Efficacy Evaluation of Seed Dressing with Tetrazolamide on Spodoptera frugiperda in Maize Field
摘要
Abstract
In order to clarify the control effect of tetrazolamide seed dressing on Spodoptera frugiperda in maize field,in this study,indoor and field evaluations were carried out by dressing the maize seeds with different dosages of 20%of tetrazolamide SC(0.5,1.0,5.0,1.5,and 2.5 g/kg)and the control with different dosages of 20%of chlorantraniliprole SC(1.5,2.5,and 5.0 g/kg).The results of indoor efficacy determination showed that different dosages of the two agents were safe for both maize emergence and growth.After 10 days of emergence,the seed dressing treatments with 5 dosages of 20%of tetrazolamide SC showed better control effects on Spodoptera frugiperda,reaching more than 98.28%.The control effect of 20%of chlorantraniliprole SC seed dressing treatments with dosages of 2.5 and 5.0 g/kg was better,reaching 84.48%and 93.10%,respectively,while the control effect of 1.5 g/kg treatment was poor.After 20 days of emergence,the control effect of 20%of tetrazolamide SC treatments with 2.5 and 5.0 g/kg was better,with the control effect of 76.27%and 84.75%,respectively.The control effect of other treatments and the 20%of chlorantraniliprole SC was poor.The results of the field efficacy test showed that the control effect of maize seedlings treated with 20%of tetrazolamide at dosages of 2.5 and 5.0 g/kg at 25 days after emergence was more than 80%.The control effects of 20%of chlorantraniliprole SC at 15 and 25 days after different treatments were poor.Therefore,the use of 20%of tetrazolamide at dosages of 2.5 and 5.0 g/kg for maize seed dressing treatment had a good control effect on S.frugiperda in both rapid and sustained effects,which could reduce the damage caused by S.frugiperda.关键词
