杀菌剂对蘑菇疣孢霉病的防治效果比较

Comparison of Control Effect of Fungicides against Agaricus bisporus Wet Bull Caused by Mycogone perniciosa Magn

通过在菇房中11种杀菌剂对蘑菇疣孢霉病防治效果和对双孢蘑菇生长影响试验,结果表明,11种杀菌剂对蘑菇疣孢霉病防治效果和对双孢蘑菇生长影响有明显差异,其中特克多45%悬浮剂500倍液无论是覆土处理或转潮时喷雾覆土处理,均对疣孢霉病有较好的防治效果,防治效率分别达93.7%和89.1%,且对双孢蘑菇菌丝生长和子实体发育无不良影响。其它杀菌剂综合表现均不理想。

11 kinds of fungicides were selected to test their control effect against Agaricus bisporus wet bull caused by Mycogone perniciosa and the effect on the growth of Agaricus bisporus in the mushroom house were tested. The results indicated that 11 kinds of fungicides had obvious difference towards control effect against Agaricus bisporus wet bull caused by Mycogone perniciosa and effect on the growth of Agaricus bisporus. Among them, 45% EW with 500 times liquid of Thiabendazol was the best with the control effect of 93.7% by covering soil and 89.1% by dealing cover soil with spraying during fruiting period. Meanwhile, it had not adversary effect on mycelial growth and fruit body development of Agaricus bisporus. Comprehensive performance of the other fungicides were non-ideal.
