矢尖蚧发生普遍,为害严重,是柑桔果树上最难防治的重要害虫之一。近年研究虽有一定进展,准确掌握在第一代幼蚧盛期喷用机油乳剂＋有机磷混合液或国产扑虱灵以及国外产的速扑杀等有较好防治效果,但对成蚧几乎无效,至今尚缺乏对矢尖蚧成虫、若虫兼治的理想药剂。因此,一旦错过若虫盛期,防治很难奏效;四川省新津县成教化工厂生产的顽虫毙粉剂,不仅对矢尖蚧若虫具有100%的防治效果,而且对雌成虫的防效可高达85%以上,是国内近年来继扑虱灵、国外速扑杀之后杀蚧药剂研制上的重大突破,它的问世将使矢尖蚧及其它蚧虫的药剂防治提高到一个新水平。
Cornucopiae widespread, serious damage, is one of the most difficult pest control citrus fruit tree. In recent years, although some progress has been made in the research, it is believed that there is a good prevention and cure effect in the first generation of mealybugs sprayed with oil emulsion + organic phosphorus mixture or domestic melatonin, Invalid, so far there is a lack of the arrow stem scale adults, nymphs and the ideal agent. Therefore, once miss the peak of nymphs, prevention and treatment is very ineffective; Chengjin Chemical Plant in Xinjin County, Sichuan Province, the production of refractory powder, not only on the scale nymph nymphs have a 100% control effect, but also against adult females up to 85 % Or more, is a major breakthrough in the research and development of the scale agent in the country following poplar and foreign quick culling in recent years, its advent will bring the chemical control of the arrowhead scale and other scale insects to a new level.
