摘要

这些试验是在MT Billings附近的灌溉春小麦和大麦田里进行的。地块宽10英尺,长30英尺,按照RCB设计安排,有5个处理,3块小麦,4个处理,3块大麦。杀虫剂于6月3日使用二氧化碳动力背包喷雾器进行喷洒,该喷雾器配有10英尺长的手持喷雾器和Teejet 8001扁平风扇喷嘴。经过校准,喷雾器在20 psi的压力下可输送10.5加仑/英亩。通过对每个处理和未处理重复的50个随机选择的旗叶上的CLB幼虫计数来测定杀虫剂的药效。数据采用方差分析,处理方法采用LSD检验。

Cereal Leaf Beetle Control in Wheat and Barley, 1992:
These tests were conducted in irrigated spring wheat and barley in fields located near Billings, MT. Plots were 10 ft wide by 30 ft long and were arranged according to a RCB design having 5 treatments with 3 blocks for wheat and 4 treatments with 3 blocks for barley. Insecticides were applied on 3 Jun with a CO2-powered backpack sprayer equipped with a 10-ft hand held spray boom and Teejet 8001 flat fan nozzles. The sprayer was calibrated to deliver 10.5 gal/acre at 20 psi. Insecticide efficacy was determined by counting the number of CLB larvae on each of 50 randomly selected flag leaves from each treated and untreated replicate. Data were subjected to ANOVA, and treatment means were separated by LSD test.
