为有效防治松材线虫病,采用阿维菌素和甲维盐为主药,吐温等为表面活性剂,复配混合药剂;同时,模制长喙50 m L容积药瓶,组合成适合向松树注输药物的专用注射针剂,在松材线虫病发生林地开展树干注入药剂抗松材线虫病试验。林间抗松材线虫病试验,采用2种方法进行,即树干注入药剂后作人工接种病原松材线虫和自然感染病原松材线虫;同时,用日本专用松材线虫病预防注射剂作对比试验。结果表明,日本药物(A类药)对人工接种病原松材线虫具有75%的预防效果;自配的阿维菌素(C21类药)和甲维盐(C22类药)对人工接种获得50%和100%的预防效果,使自然感染松材线虫病的松树死亡率平降至2.70%;而对照试验的人工接种病线虫的松树死亡率为100%,自然感染松树死亡率为22.36%。结果表明:试验开发的松树注射剂阿维菌素C21和甲维盐C22,能有效预防松树个体的松材线虫病发生与危害。
In order to effectively control pine wilt disease, avermectin and carbaryl salt as the main drug, Tween and other surfactant, compound with mixed agents; the same time, the long beak 50 m L volumetric flask molded, combined into a suitable Injection of pine needle injection of drugs for injection, in the pine wood nematode occurrence forest trunk injection of agents against pine wood nematode disease test. Forest anti-pine nematode disease test, using two methods, namely the trunk after injection of artificial insecticide inoculated pathogen pine wood nematode and natural infection of pine wood nematode; the same time, Japan for the control of pine nematode injection for comparison test. The results showed that the Japanese drug (Class A) had a 75% preventive effect on the artificial inoculation of pathogen pine wood nematode; the 50% of the avermectin (C21) and the carbaryl (C22) % And 100%, respectively. The mortality of pine trees naturally infected with pine wilt disease was reduced to 2.70%. The pine mortality of the artificial inoculation nematode was 100% and that of natural infected pine was 22.36%. The results showed that the pine injection of Abamectin C21 and Ciba salt C22 could effectively prevent pine wilt disease and its occurrence.
