摘要
蘑菇害螨严重地影响着蘑菇安全生产,尤其是蓝氏布伦螨Brennandania lambi(krczal)。鉴于常用农药敌敌畏防螨效果日趋下降,从而选用新农药73％克螨特乳油(以下简称克螨特)及其复配农药,不仅防螨效果较好,而且对人类安全无毒。克螨特对蓝氏布伦螨致死中量剂量L_(D50)为197.2—342.9 ppm。复合配方效果更佳。覆土后待菌丝生长进入粗土后施用较安全。
It is reported that Brennandania lambi resists increasingly insecticide DDV day by day. 73% oil emulsion of Uniroyal chemical and its mixtures compounded with diverse microbial pesticides are more effective in controlling this mite, and are nontoxic to human body. The median lethal dose is 197.2—342.9ppm. The result of application of any mixture is better than that of single miticide. It is more safety to spray the new miticide after hyphae grow into the casing of mushroombed.
