“140”是一种新型的细菌杀虫剂,菌种是湖北省微生物研究所从棉花小造桥虫中分离出来的一株产晶芽孢杆菌,分类学上属于苏云金杆菌的无鞭毛新变种,定名为“武汉杆菌”。 几年来,我们先后在瑞金等九个县、市进行了多点大田药效试验和大面积防治使用,收到了显著的效果。实践证明,“140”杀虫菌对水稻稻苞虫、稻纵卷叶虫、稻螟蛉、稻眼蝶、莱青虫、小莱蛾、莱螟、豆青虫、烟青虫、玉米螟、高粱条螟、棉花卷叶虫、小造桥虫、茶毛虫、茶尺蠖、柑桔凤蝶、梨刺蛾、舟行毛虫、木撩尺蠖、松毛虫等数十种农、林、蔬莱、果树害虫毒力显著,防治效果均在百分之八十以上;对棉铃虫、红铃虫、金刚钻、水稻二化螟、甘蔗二点螟等也有较好的效果。 “140”杀虫剂具有一般化学农药所没有
“140” is a new type of bacterial insecticide. The strain is a new strain of Bacillus natto that was isolated from the cotton plant of Zoobenthos chinensis in Hubei Province and is a new non-flagellum species taxonomically belonging to Bacillus thuringiensis. Named “Wuhan bacillus.” In recent years, we have carried out more field trials and large-scale prevention and control trials in nine counties and cities such as Ruijin and received remarkable results. Practice has proved that the “140” insecticides on rice Budworm, rice leaf roller, rice borer, rice butterfly larvae, Lepidoptera, Lepidoptera, Pest insects, tobacco budworm, corn borer, sorghum borer , Dozens of species of agriculture, forestry, vegetables and fruit pests and insect pests such as cotton leaf roller, small bridge insect, tea caterpillar, tea scallop, citrus swallowtail butterfly, pear thorn moth, Significantly, the control effect was over 80%, and also had good effects on cotton bollworm, pink bollworm, diamond, rice stem borer, sugarcane borer. “140” insecticides have the general chemical pesticides do not have
