我省红苕栽种面积居全国第一,产量約占粮食总产的20％以上,红苕黑斑病是红苕丰产和安全贮藏的大敌,不少地区危害相当严重,損失很大。近几年来,我们与群众性科学实验相结合,采用磷化钙、二硫化碳等熏蒸窖藏紅苕,做了大量的工作,取得一定成效。但上述药物属高毒熏蒸剂,对人毒性大,使用时需具有防毒设备,同时防效也不够理想。为了寻找高效低毒的新药物,我们对近几年来国内研制的20余种杀菌剂
Red Clover planting area in our province ranks first in the country, the output accounts for about 20% of the total grain output, red crab black spot disease is the enemy of high yield and safe storage, in many areas the damage is very serious, a great loss. In recent years, we combined with the mass scientific experiments and used calcium phosphide and carbon disulfide to fumigate and store red yeast rice. We have done a great deal of work and achieved some success. However, the above-mentioned drugs are highly toxic fumigants, toxic to humans and need to be used with anti-virus equipment, while the control effect is not satisfactory. In order to find new drugs with high efficiency and low toxicity, we have studied more than 20 kinds of bactericides developed in China in recent years
