油菜菌核病在我国分布广,危害重,特别在长江流域及西南地区尤为突出。一般年份发病率为10—30%,严重者达80%以上。当前,各地防治油菜菌核病的药剂有些虽然使用广、价格低,但药效不稳定;有些药效好,但价格昂贵,农民很难承担。针对这种情况,我们有了开发以多菌灵与菌核净为主的复配制剂的设想,并对其抑制子囊孢子萌发,菌丝生长进行了毒力测定。现报告如下: Sclerotinia sclerotiorum widely distributed in our country, endangering heavy, especially in the Yangtze River and southwest China is particularly prominent. The average annual incidence of 10-30%, severe cases of more than 80%. At present, some pesticides that control rape sclerotinia are widely used and low in price, but their pharmacodynamic effects are not stable. Some are effective but expensive, and peasants are hard to afford. In view of this situation, we have developed a concept of carbendazim and sclerotiorin-based complex formulations, and its inhibition of ascospore germination, mycelial growth was measured. The report is as follows:
