甘蓝主要病虫害绿色防控试验示范初报

Demonstration Report on Green Control Test of Main Pests and Diseases of Cabbage

为有效防治甘蓝病虫害,探讨植物促生诱抗剂"普绿通"对甘蓝病虫害的防治作用,研究防治甘蓝病虫害的绿色防控措施,特在息烽县石硐镇石硐村甘蓝种植基地开展甘蓝主要病虫害绿色防控试验示范。示范结果表明,利用"普绿通"浸种、浸根、苗期和大田期喷雾,对增强甘蓝植株长势,提高其对病害的免疫能力,减轻病毒病、霜霉病、黑斑病等病害的发生具有重要的作用。同时,通过应用黄板诱蚜、释放七星瓢虫捕食蚜虫、性诱剂诱杀小菜蛾雄虫、植物源农药防控菜青虫和蚜虫、高效安全农药精准使用技术等绿色防控技术措施,可以有效地减少化学农药的用量,降低项目示范区甘蓝农药残留,提高甘蓝品质。

In order to effectively control the disease and insect pests of cabbage,this paper discusses the prevention and control effect of the plant promoting and elicitor of ＂ Putonglv＂ on the disease and insect pests of cabbage,and studies the green prevention and control measures against the disease and insect pests of kale,which was carried out in the kale planting base of shidong town,shidong town,Xifeng county. Results show that the use of ＂ Putonglv ＂ seed,root and seedling stage and field spray,to strengthen the cabbage plants grow,improve its immunity to disease,virus disease,the occurrence of downy mildew and black rot disease plays an important role. At the same time,by applying the yellow plate aphid,release the lady beetle lure prey aphids,sex lures traps in DBM male,botanical pesticides to control caterpillar and aphids,efficient and safety pesticides green control technology measures,such as precision using technology can effectively reduce the amount of chemical pesticides,reduce project demonstration zone kale pesticide residue,improve the quality of the cabbage.
