利用超低容量喷雾器喷洒农药防治园林中苗木和幼树的病虫害,具有省工、省药、效果好和应用原液喷洒适于缺水山区及干旱地区使用等特点。我们曾用超低容量喷雾器(上海光明仪表厂产品) 喷80%敌敌畏乳油原液、40%乐果乳油原液、50%1059乳剂原液防治光肩星天牛成虫,喷药24小时后成虫均死亡,杀虫效果达98%以上。如果用上述农药的800倍稀释液在1.5米高的幼树上喷洒200毫升左右,对光肩星天牛成虫杀虫率仍能达
The use of ultra-low-volume sprayer spray pesticide prevention and control of garden seedlings and young trees pests and diseases, with labor, medicine, good effect and the application of liquid spray suitable for dry and mountainous areas and other features. We used 80% dimethoate EC, 40% dimethoate EC, 50% 1059 emulsion to control adults of Anoplophora glabripennis with ultra-low capacity sprayer (Shanghai Guangming Instrument Factory). After 24 hours spraying, the adults died and the insecticidal effect reached More than 98%. If you use the 800 times diluted pesticides in the 1.5-meter-high saplings sprayed about 200 ml, the insecticidal rate of the light Shijian Tian Bei adults can still reach
