木霉(Trichoderma spp)是污染食用菌的重要害菌,特别对袋栽香菇威胁较大.目前各地菇农普遍用多菌灵作添加剂以抑制木霉的生长,由于长期单一使用和滥用药剂,久而久之便产生了木霉的抗药性和公害两大矛盾.因此,寻找新的、低残留的杀菌剂已成了当务之急.为此,笔者用新农药保美生对木霉作了抑菌效果和防治试验,并测定了它对香菇等8种食用菌生长发育的影响,取得较满意的效果,现简报如下:
Trichoderma spp is an important harmful bacterium to contaminate edible fungi, especially threatening to bag mushrooms.Nowadays, all kinds of mushrooms are commonly used as additive to inhibit the growth of Trichoderma, because of long-term single use and abuse of medicaments, Over time will have two major contradictions of Trichoderma resistance and pollution Therefore, the search for new, low residual fungicides has become a top priority.To this end, the author of the new pesticide Pauli on Trichoderma antibacterial effect and Control test, and determined its mushrooms and other 8 kinds of mushroom growth and development, and achieved more satisfactory results, are briefed as follows:
