摘要
2021年在广西蒙山县蒙山镇甘棠村金秋砂糖桔种植园柑桔木虱若虫发生初盛期,开展了常用杀虫剂螺虫乙酯、噻虫嗪和阿维菌素防治柑桔木虱的田间试验.结果表明,22.4％螺虫乙酯SC 4 000倍液、21％噻虫嗪SC 3 360倍液、1.8％阿维菌素EC 1 440～2 000倍液对柑桔木虱若虫防治效果在82％以上,均有较好的防治效果;其中,1.8％阿维菌素EC 1 440倍液和21％噻虫嗪SC 3 360倍液的防治效果相对更好,药后15 d时仍然分别可达96.07％和93.91％,两者防治效果差异不显著.3种药剂的持效期均可达15 d以上,可在柑桔木虱若虫发生初盛期交替使用.
Abstract
In 2021,a field experiment was conducted for the control of citrus psyllid nymphs with commonly used insecticides such as Spirotetramat,Thiamethoxam,and Avermectin in Jinqiu Shatangju orchard in Gantang Village,Mengshan Town,Mengshan County,Guangxi.The results showed that the control effect of 4,000-time diluted 22.4％Spirotetramat SC,360-time diluted 21％Thiamethoxam SC,and 1,440-2,000-time diluted 1.8％Avermectin EC on citrus psyllid nymphs was over 82％,with good control effects.Among them,the prevention and control effects of 1,440-time diluted 1.8％Avermectin EC and 360-time diluted 21％Thiame-thoxam SC were relatively better,with control efficiency reached to 96.07％and 93.91％,respectively,after 15 days of treatment,and no significant difference between two treatments.The effective duration of all three pes-ticides could reach more than 15 days.They can be alternately used in the initial and peak stage of the occur-rence of citrus psyllid nymphs.
