摘要
采用2种不同体积的载水剂，评价了氯菊酯航投防ECB的性能。试验地点是一块135.9公顷的商业玉米田，位于明尼苏达州斯特恩斯县Sauk中心以北，于5月5日种植，产量为71,662株/公顷。稻田面积为15.2 m × 304.8 m(行距0.91 m)，稻田面积为15.2 m × 304.8 m，施用氯菊酯0.17 kg(AI)/ha，分别以18.7 l /ha和28.01 l /ha的水处理。处理被安排在一个随机完全区，4个重复。使用配备MultiTeeJet(46芯)的Piper Brave在15米范围内施用杀虫剂。7月13日晚上6-9点，在微风(4.8-14.5 km/h)和中等温度(17.8-21.1℃)条件下，使用7个旋转器喷嘴。9月22日，通过在每个地块5个地点解剖10株植物并记录每个植物的隧道数量来评估绩效，11月8日通过收获地块来评估绩效。用于分析数据的统计程序包括方差分析和LSD。
Control of First Generation European Corn Borer, 1992
Performance of aerially applied permethrin against ECB was evaluated using 2 different volumes of water carrier. The site was a 135.9 ha commercial corn field located north of Sauk Centre, Stearns county, MN, planted on 5 May, at a population of 71,662 plants/ha. The plots, which measured 15.2 m by 304.8 m (0.91 m row spacing), were established on 12 Jul. Treatments included permethrin @ 0.17 kg(AI)/ha aerially applied with 18.7 liter/ha water and 28.01 liter/ha water and an untreated check. Treatments were arranged in a randomized complete block with 4 replications. Insecticides were applied in a 15 m swath by a Piper Brave equipped with MultiTeeJet (46 core with no. 7 spinner) nozzles on 13 Jul from 6-9 pm under light winds (4.8-14.5 km/h) and moderate temperatures (17.8-21.1 C). Performance was evaluated on 22 Sep by dissecting 10 plants at 5 locations per plot and recording the number of tunnels per plant, and on 8 Nov by harvesting the plots. Statistical procedures used to analyze the data include ANOVA and LSD.
