噻嗪酮飞机防治稻飞虱的应用技术

Technique Controlled Rice Planthoppers byAircraft with Buprofezine

利用噻嗪酮在水稻茎叶内吸机理，在１９９１～１９９３年进行飞机防治稻飞虱试验并推广应用２１４架次，６４２００亩，飞机防治具有快速、安全、持效的优点。飞机防治适期宜在本区７月下旬至８月上旬稻飞虱低龄若期，达到压前控后目的，噻嗪酮用量应根据稻飞虱发生量及控虫期而定，中等年份用有效成分３Ｏ克，重发年份用４Ｏ克。飞机防治时，噻嗪酮可和有机磷杀虫剂、三环唑、肥料等混用兼治纵卷叶螟、稻瘟病等其他种类病虫。

Because of high effect and systemic properties,buprofenzine was used to control rice planthopper withaerosprayer along the north castal area of Jiangsu province in1991～1993.The advantages of aerosprayer were rapid,safeand better persistence. The optimum period to apply the insec-ticide was from late of July to early of August when the_pestwas low instarnymph.The dosage of application was based onthe population of planthopper and hatching time of nymphfrom 450～600 g a.1./h.Buprofenzine can be combined withorganophosphorous insecticides , tricyclazole and fungicides tocontrol rice leaf roller and blast.Buprofenzine can be used withfertilizer.
