| 摘 要： | 2000年在安徽省庐江县试验研究常用杀螟药剂45%杀虫双SP喷雾和药土撒施对二化螟的防治和保苗效果。结果表明,每公顷有效成分为472.5、607.5和742.5g喷雾的虫口减退率分别为89.5%、95.0%和95.9%,药土撒施分别为87.6%、92.3%和93.1%。保苗效果变化趋势与虫口减退率基本一致。可见,每公顷施用607.5g是比较适宜的。药土撒施虽防效下降2～3个百分点,但施用简便,对天敌影响小,故认为比较经济适用。

Performances of Spray and Dusting of Disultap for Control of the Rice Stem Borer, Chilo suppressalis in China |
| |
| Abstract: | In2000,field experiment was conducted on performance of45%disultap SP for control of the rice stem borer,Chilo suppressalis(Walker)in Lujiang County,Anhui Province where the pest was severe.The result showed that the larval mortality were89.5%,95.0%and95.9%in treatments sprayed with472.5g,607.5g and742.5g(a.i./hm 2 ),respectively,and87.6%,92.3%and93.1%in treatments dusted with the same dosages,respectively.The changes in num-bers of damaged plants were roughly the same as the larval mortality.The dusting application method was easy and less harmful to natural enemies,so it was effective and cost saving.Consid-ering material cost,the authors suggest to use the dosage of607.5g for the present. |
