| 摘 要： | 柑桔黄龙病是世界性的毁灭性病害,柑桔木虱是其唯一自然传播媒介,控制柑桔木虱是柑桔黄龙病综合防治最重要的技术措施.柑桔木虱成虫的高效传病性、近距离扩散性和快速传病性,决定了用来防治柑桔木虱成虫的农药要求速效性好、防效高(药后24h的防效＞95%).由于受到试验地虫源和试验条件的限制,柑桔木虱的有效防治药剂筛选严重滞后.2007-2008年做了13种农药的田间小区药效试验和3种农药的大面积应用试验,结果表明:增效联苯菊酯EC 25 mg(a.i)/L、雕杀EC 110 mg(a.i)/L、铁骑EC 83 mg(a.i)/L对柑桔木虱成虫药后24 h的防效达100%;喹硫磷EC 250 mg(a.i)/L、杀扑磷EC200 mg(a.i)/L、稻丰散EC 333 mg(a.i)/L对柑桔木虱成虫药后24 h的防效＞95%;防效在94.9%～85%的有丁硫克百威EC 200 mg(a.i)/L、霸中霸EC 200 mg(a.i)/L;吡虫啉WP 100 mg(a.i)/L、阿维·丁硫EC 90 mg(a.i)/L、甲基嘧啶磷500mg(a.i)/L的防效分别为92.3%～74.4%、79.1%、73.1;防效低于40%的药剂有吡蚜酮WP 250mg(a.i)/L、印楝素EC 6 mg(a.i)/L.

| Abstract: | Abstract: Huanglongbing (HLB) is a destructive disease. It has spread to Brazil and America .In the orchard, its only vector is citrus psylla.Control of citrus psylla is the most important technical component of an integrated control program for huanglongbing. Adult psyllid control provided by pesticides must be >95% after 24h sprayed.13 pesticides was tested in field experiments. The results show that adult psyllid control provided by imidacloprid plus methomyl plus beta-cypermethrin 83 mg(a.i)/L and fenpropathrin plus triazophos plus quinalphos 110mg(a.i)/L and bifenthrin plus azone 25mg(a.i)/L was 100%, the control of quinalphos 250mg(a.i)/L and methidathion 200mg(a.i)/L was 99.0% to 96.8%, the control of phenthoate 500mg(a.i)/L was 100% to 91.4% ,while pirimiphos-methyl 500 mg(a.i)/L only gave 73.1%, toosedarin 6 mg(a.i)/L,pymetrozine 250 mg(a.i)/L each provided <40% control. |
