蔬菜的细菌性病害种类多、为害重。如黄瓜角斑病,在低温多雨的季节可以造成毁灭或半毁灭性为害。过去唯一有效的药剂是优质链霉素,品质不佳效果不好,因此与医药供应“争嘴”。而西德、日本等国从保护人的抗性出发,禁止在农产品上使用链霉素,但也没有找到杀细菌的有效农药。我们通过三年试验示范证明,齐齐哈尔化工研究所合成的 DT 杀菌剂是防治黄瓜细菌性角斑病的一种好药剂,平均防治效果达86.16%,增产28.6%,比医用链霉素的防止效果还提高15.25%。
Bacterial diseases of vegetables and more types of harm. Such as cucumber angular leaf spot, in the cold and rainy season can cause destruction or semi-destructive damage. In the past the only effective agent is a high-quality streptomycin, the poor quality of the result is not good, so with the pharmaceutical supply “contention.” However, countries such as West Germany and Japan banned the use of streptomycin on agricultural products from protecting human resistance, but no effective pesticide to kill bacteria was found. We passed the demonstration of three years of demonstration that the DT fungicide synthesized by Qiqihar Institute of Chemical Technology is a good agent for preventing and controlling cucumber bacterial angular leaf spot, with an average control effect of 86.16% and an increase of 28.6%, which is better than that of streptomycin Also increased by 15.25%.
