摘要
通过室内盆栽试验研究了20%氯虫苯甲酰胺SC等10种药剂对水稻三化螟的药效,并在此基础上,选取6种防效较好的药剂进行大田试验,研究田间防治效果、施药次数对三化螟控制作用以及评价这些药剂对稻田生态系统内其它生物的影响。试验结果表明,20%氯虫苯甲酰胺SC对三化螟防效最好,不会造成褐飞虱的猖獗发生和严重杀伤天敌;58%噻嗪.杀虫单WP对三化螟和稻褐飞虱都具有较好防效,但是对天敌有较大杀伤作用;8%三唑磷EC和14.5%吡虫.杀虫单ME对三化螟具有一定防效,但是造成褐飞虱的猖獗发生。所有6种药剂施药1次均不能有效防治三化螟,而施药2次20%氯虫苯甲酰胺SC等4种药剂对三化螟具有明显控制作用。
The laboratory control effect of ten pesticides to the yellow rice borer was studied.On above basis,six pesticides were chose to test in the fields.The field control effect,application rate of pesticides,the effect to other important rice pest and natural enemy also were studied.The field results showed that chlorantraniliprole 20% SC had best control effect to yellow rice borer than other tested drugs.And it didn＇t caused resurgence of brown plant hopper and don＇t impact the natural enemies largely.Buprofezin ＋ monosultap 58% WP also had good control effect to yellow rice borer.However,it killed natural enemies including spider and plant bugs seriously.Triazophos 8% EC and imidaclopri ＋ triadimefon 14.5% ME had a little control effect to yellow rice borer,but it caused resurgence of brown plant hopper.Moreover,all of those six types of pesticides must be applied twice to control the yellow rice borer successfully.
