乐杀螨是沈阳化工研究院研制成的一种新型杀螨剂.经过几年的室内及田间试验证明:乐杀螨是一种高效、安全、选择性好的杀螨剂,可有效地防治苹果、茶叶、棉花、柑桔、菜豆及花卉上的多种害螨,且有很好的杀卵效果.还可用来防治白粉病.乐杀螨是二硝基苯类杀螨剂.纯品不溶于水,但溶于多数有机溶剂.在浓酸和稀碱中不稳定.紫外光能引起其缓慢分解.无腐蚀性.乐杀螨的制剂为40%乳油.生产上使用浓度为2000—2700倍液,防治苹果、桃等上的山楂叶螨速效为72.9—100%,持效期可达30天;残效为87.9—97%.防治效果与目前生产上常用的三环锡基本相同.据国外资料介绍:使用乐杀螨防治后,螨类不易产生抗性.这对解决一些常用杀虫杀螨剂,如乐果、三氯杀螨醇等使螨类产生抗性问题具有重要意义.
Lethal mite is a new type of acaricide developed by Shenyang Chemical Research Institute.After years of indoor and field trials have shown that: Acaricus is an efficient, safe and selective good acaricide that can effectively control Apple, tea, cotton, orange, beans and flowers on a variety of pest mites, and have a good ovicidal effect. Can also be used to control powdery mildew. Leer mite is dinitrophenyl acaricide. Insoluble in water, but soluble in most organic solvents. In concentrated and dilute alkali instability.Ultraviolet light can cause it to decompose slowly.Non corrosive.Serorice mites preparation is 40% EC.Production use of the concentration of 2000- 2700 times, prevention and control of apples, peaches and other hawthorn spider quick-acting effect of 72.9-100%, persistence up to 30 days; residual effect of 87.9-97% .Prevention and control of the current production of tricyclic tin is basically the same. According to foreign information: the use of music to kill mites prevention and control, mites difficult to produce resistance.This is to solve some common insecticidal acaricides, such as dimethoate, dicofol and other mites to produce resistance is of great significance.
