摘要
为筛选出对荞麦田西伯利亚龟象害虫具有良好防效的药剂,对7种不同药剂进行药剂种类、浓度、用药时间、药剂配合等方面的筛选,根据防效,总结防治措施。结果表明:可直接采用70%噻虫嗪种子处理可分散剂拌种进行防治,发生严重时播种后4~5 d至幼苗出土前发现西伯利亚龟象甲为害时,可使用8%丁硫·啶虫脒乳油按450~600 mL·hm^-2兑水450~675 kg·hm^-2均匀喷洒地面;或播种前用60%吡虫啉种子处理分散粉剂1600倍液拌种,出苗后再使用丁硫·啶虫脒乳油450~600 mL·hm^-2兑水450~675 kg·hm^-2均匀喷洒幼苗及地面,防效可达90%以上。
In order to screen out the insecticides with good control effect on Rhinoncus sibiricus Faust in buckwheat field,seven different pesticides were screened from the aspects of insecticide type,concentration,medication time and pesticide combination,and the control measures were summarized according to the control effect.The results showed that 70%thiamethoxam seed treatment dispersant could be directly used to control the disease.When serious damage occurred 4-5 days after sowing to the time when Rhinoncus sibiricus Faust was damaged,8%acetamiprid EC could be sprayed evenly on the ground with 450-600 mL·hm^-2 water and 450-675 kg·hm^-2,or treated with 60%imidacloprid seed before sowing.The results showed that the control effect could reach more than 90%when the seeds were treated with 600 times of liquid,and then the seedlings and ground were evenly sprayed with the mixture of 450-600 mL·hm^-2 of buprofezin EC and 450-675 kg·hm^-2 of water.
