| 为筛选出适宜江西双季稻田常见病虫害的新型高效药剂, 选用9种农药进行田间药效试验。结果表明:9种药剂在中高浓度下对防治对象均可达到较好的效果。其中10%溴氰虫酰胺OD 45 g/hm2(有效成分用量，下同)对早稻田二化螟防效最佳, 药后28 d防效达93.22%;30%唑虫酰胺SC 67.5 g/hm2对稻纵卷叶螟防效最好, 药后28 d防效达87.50%;10%四氯虫酰胺SC防治螟虫使用成本最低, 为108元/hm2。10%氟啶虫酰胺WG 90 g/hm2对白背飞虱的防效最好, 药后26 d防效为90.17%;22%氟啶虫胺腈SC 90 g/hm2对褐飞虱防效最佳, 药后26 d防效为97.54%, 且应用成本最低(204元/hm2)。25%吡唑醚菌酯EC 90 g/hm2对水稻纹枯病、稻瘟病的防效最高, 分别为98.13%、96.49%;20%烯肟·戊唑醇SC使用成本最低, 为81元/hm2。以上结果可为双季稻田相关病虫害防控药剂的选择提供依据, 同时为供试药剂在双季稻田的推广应用提供参考。 |

| In order to select new high efficiency pesticides, which are suitable for common diseases and insect pests control in double cropping rice fields in Jiangxi, nine kinds of pesticides were selected for field experiment. The test results showed that all the nine pesticides showed good control effects at medium and high concentrations. Among them, cyantraniliprole 10% OD (45 g/hm2 active ingredient dosage, the same below) had the best efficacy on Chilo suppressalis in early rice field, with the efficacy of 93.22% 28 days after spraying. Tolfenpyrad 30%SC 67.5 g/hm2 had the best field efficacy on rice leaf roller, with the efficacy of 87.50% 28 days after spraying. Chlorantraniliprole 10% SC had the lowest cost of 108 yuan/hm2. Flonicamid 10%WG 90 g/hm2 had the best field efficacy on white backed planthopper, with the efficacy of 90.17% 26 days after spraying. Sulfoxaflor 22% SC 90 g/hm2 had the best control effect on brown planthopper, with the efficacy of 97.54% 26 days after spraying, and it had the lowest cost of 204 yuan/hm2. Pyraclostrobin 25% EC 90 g/hm2 showed the highest control effect on rice sheath blight and rice blast with the efficacy of 98.13% and 96.49%, respectively. Enestroburin·tebuconazole 20% SC had the lowest cost of 81 yuan/hm2. The above results can provide a certain reference for the prevention and control of related diseases and insect pests in double cropping rice fields, as well as a reference for the promotion and application of tested pesticides in double cropping rice fields. |
