上海农药研究所研制和经销的机油乳剂,是一种高效、低毒、安全、使用方便、价格低廉,防治果、林介壳虫和螨类的理想药剂。 一、杀虫机理和防治对象 机油乳剂在害虫及其卵的表面能形成一层油膜,阻塞气孔,造成窒息致死。同时,由于机油中有一部份被磺化的不饱和烃类化合物,在光和空气中被氧化成酸类,而产生杀虫活性。所以机油乳剂的杀虫机理,既有物理性的窒息作用,又有化学性的毒杀作用。
Shanghai Institute of pesticides developed and distribution of the oil emulsion, is a high efficiency, low toxicity, safety, easy to use, low cost, control fruit, forest scale insects and mites ideal agent. First, the insecticidal mechanism and control object Oil emulsion in the pests and their eggs to form a layer of film on the surface, blocking stomata, causing suffocation to death. At the same time, insecticidal activity is generated as a part of sulfonated unsaturated hydrocarbon compounds in the oil are oxidized to acids in light and air. Therefore, the insecticidal mechanism of the oil emulsion, both physical asphyxia effect, there are chemical poisoning effect.
