摘要
介绍了一种对瓜蚜具有很好的控制作用的根用吡虫啉控释片剂。2009年中宁大青山地区瓜蚜严重发生,7月6日瓜蔓上瓜蚜虫口数量为485.2头/株,对西瓜造成较明显危害,而根用控释农药片剂施药区的虫口数量仅为5.12头/株。供试根用控释农药片剂对瓜蚜具有很好的控制作用,每株1粒的施药量,在播种时随种子施药,对瓜蚜具有70d以上的控制作用,控制效果在95%以上,且经检测对压砂瓜安全。
A controlling technology of control-releasing imidacloprid tablet for root using against Aphis gossypii Glover was introduced. Aphis gossypii Glover occurred seriously in 2009 at daqing mountain of zhongning county. Amount of Aphis gossypii Glover in each tendril was 485.2, which caused obvious damage. While number of Aphis gossypii Glover was 5.12 in controlled area by control-releasing pesticide tablet. Control-releasing pesticide tablet for root using had good control effect against Aphis gossvpii Glover. The dosage of Control-releasing imidacloprid tablet was one granule in an individual plant of watermelon and imposing it with seed down.
