通过田间试验研究卫福200FF和杀虫剂UBI6707(30%)液剂混用在春小麦上的应用效果。结果表明:卫福200FF和杀虫剂UBI6707(30%)混用处理100kg种子以卫福200FF300ml+UBI6707(30%)液剂133ml为好,防治黑穗病效果达76.78%,地下害虫防效达94.86%。同时该药剂在此剂量下,不仅对植株生长无不良影响,而且还可提高出苗率,并且对小麦根际、穗粒数、千粒重均有刺激生长作用,其中出苗率比空白对照提高2.5个百分点,穗粒数增加4.8粒,千粒重增加2.6g,增产19.7%。
Field experiments were conducted to study the application effect of WeiFu 200FF and insecticide UBI6707 (30%) on spring wheat. The results showed that the combination of Wei-fu 200FF and insecticide UBI6707 (30%) treated with 100kg of Weihong 200FF300ml + UBI6707 (30%) was better, the effect of preventing and treating smut was 76.78%, and the underground pest control efficiency was 94.86 %. At the same time, the agent not only had no adverse effect on plant growth, but also increased the germination rate, and stimulated the growth of wheat rhizosphere, grains per spike, and 1000-grain weight. The rate of emergence was 2.5 percentage points higher than that of the blank control , Grain number increased by 4.8 kernels, grain weight increased 2.6g, an increase of 19.7%.
