对双孢蘑菇侵染性病害防治中的5种化学药剂进行了筛选。结果表明,药剂喷施培养料和喷施覆土均有一定的防病作用,但施用时期不同、浓度不同效果差异较大。喷施培养料以50%多菌灵.硫可湿性粉剂1∶(1 000~1 500)倍液、75%百菌清可湿性粉剂1∶2 400倍液、30%百.福可湿性粉剂1∶2 000倍液,菌丝生长健壮、防病效果好、出菇早、出菇整齐、产量高,产量较喷施清水的对照提高2.4%~12.2%;喷施覆土以30%百.福可湿性粉剂1∶(1 600~2 400)倍液、70%福.甲硫.硫可湿性粉剂1∶(1 500~2 000)倍液,菌丝生长健壮、防病效果好、出菇早、出菇整齐、产量高,产量较对照提高31.6%~48.7%。
Five kinds of chemical agents in the prevention and treatment of Agaricus bisporus were selected. The results showed that there was a certain anti-disease effect on the spraying agent and sprayed soil, but the effect was different when the application period was different. Spraying culture materials with 50% carbendazim sulfur sulfur powder 1: (1 000 ~ 1 500) times, 75% chlorothalonil WP 1: 2 400 times, 30% 1: 2000 times of liquid, mycelium growth robust, good disease prevention, fruiting early, fruiting and tidy, high yield, the output of spraying water than the control increased by 2.4% to 12.2%; Fok WP 1: (1 600 ~ 2 400) times, 70% Fu sulfur methyl sulfur WP 1: (1 500 ~ 2 000) times the liquid, mycelium grow robust, good disease prevention and control, Mushroom early, fruiting and tidy, high yield, yield increased 31.6% ~ 48.7% compared with the control.
