红苕是我县的主要粮食作物之一,但过去窖贮保鲜问题一直没有得到解决,常年烂苕损失在30％以上,严重的超过80％。主要原因是红苕黑斑病危害所致。近年来,我县试验、示范推广了用托布津浸种,防治窖贮期红苕黑斑病的方法,取得了显著成效,病苕率和烂苕损失率分别降低到7％和5％以下。托市津是一种高效、低毒、低残留的杀菌剂,防治窖贮红苕黑斑病的成本低、方法简便、效果好、经济效益高。每处理1,000斤红苕只花0.6元钱,可挽回损失15元左右。这项技术的推广应用,解决了分户贮藏烂苕的严重 Red Clover is one of the main cereal crops in our county. However, the storage and preservation of cellar in the past has not been solved. The annual loss of rotten crabs is above 30% and seriously over 80%. The main reason is caused by red black spot disease hazards. In recent years, our county experimented and demonstrated and popularized the method of soaking Plumbagin with topiramate to prevent and cure the blackhead blight of cellar in pit storage, and achieved remarkable results. The rate of sickness and rot loss was reduced to below 7% and 5% respectively. Toshihiro City is a high efficiency, low toxicity, low residual fungicide, prevention and control of cellar storage blackheads low cost of black spot disease, the method is simple, effective and cost-effective. Each handling 1,000 pounds of red mulberry only 0.6 yuan, can save 15 yuan loss. The popularization and application of this technology has solved the serious problem of household storage rotten food
