今年包头市黄瓜细菌性角斑病流行,发病面积千余亩,未防治的已造成危害,个别地块发病株率达100%,致使黄瓜品质和产量明显下降。为鉴定由包头农科所筛选出的 DT(又名丁二酸铜、琥珀酸铜)杀菌剂防治黄瓜角斑病效果,七月上旬在1150亩(占包头市黄瓜播种面积的57.5%)黄瓜地里喷打 DT杀菌剂并结合综合防治措施,对压低田间病情,控制病情扩展,具有较明显作用。经试验用30%DT 胶
This year, Baotou cucumber bacterial angular leaf spot epidemic, the incidence of more than a thousand acres, has not been prevented the damage caused by the individual block incidence rate of 100%, resulting in cucumber quality and yield decreased significantly. In order to identify the DT (also known as copper succinate, copper succinate) fungicides screened by Baotou Agricultural Science to prevent cucumber leaf spot cucumber disease, in early July in 1150 mu (accounting for 57.5% of cucumber acreage in Baotou) cucumber DT spray fungicides in the ground and combined with comprehensive prevention and control measures to reduce the field condition, control the expansion of the disease, with a more obvious role. After testing with 30% DT plastic
