摘要
在洛杉矶温斯伯勒附近的东北研究站梅肯岭分站，将Dipel ES在选定剂量下的效果与Larvin的推荐剂量和未经处理的大豆环虫防治对照进行了比较。试验采用随机区组设计，共4个重复。在6月18日种植的R5生育期，种植5行(中心1.02米)× 9.0米的大豆。施用时使用拖拉机悬挂式抽油杆，该抽油杆配有压缩空气输送系统，每行间隔2个TX-8空心锥形喷嘴，以2.8 kg/cm2的速度输送93.6升/公顷的空气。9月1日施用杀虫剂，在第2和第7天使用标准直径38.2 cm的扫网进行2次扫网，共20次。9月2日降雨量3.0 cm, 9月3日有微量降雨。
The efficacy of Dipel ES at selected rates was compared to a recommended rate of Larvin and an untreated control for soybean looper control at the Macon Ridge Branch of the Northeast Research Station near Winnsboro, LA. The test consisted of a randomized block design with 4 replications. Plots were 5 rows (1.02 m centers) by 9.0 m of soybeans in the R5 growth stage planted 18 Jun. Treatments were applied with a tractor mounted boom equipped with a compressed air delivery system calibrated to deliver 93.6 liters/ha at 2.8 kg/cm2 through 2 TX-8 hollow cone nozzles equally spaced per row. Insecticides were applied on 1 Sep and treatments were evaluated at 2 and 7 DAT using 2 samples of 20 sweeps with a standard 38.2 cm diam sweep net. The plots received 3.0 cm rainfall on 2 Sep and a trace amount of rainfall on 3 Sep.
