田间试验证明:选择地质高燥沙壤土,轮作2~3年以上,采用宽行种植方式是防治南瓜疫病的基础。药剂防治,早期剪除中心病株,封锁发病中心是控制病害蔓延的有效措施。经温室筛选的药剂在田间防效依次为:缓释剂>甲霜灵毒土>复配药剂毒土>克露毒土。缓释剂是一种新型剂型,雨季到来前施入土壤不被雨水冲刷,缓慢释放,效果稳定,时间持久。是防治南瓜疫病、辣椒疫病理想药剂。
Field experiments show that: Selection of high-quality dry sandy loam, rotation for 2 to 3 years, the use of wide-row planting is the basis for the prevention and control of pumpkin disease. Pharmacy prevention and early removal of the center diseased plants, blocking the incidence center is an effective measure to control the spread of disease. The greenhouse effect of the selected pesticides in the field control efficacy were: sustained release agent> metalaxyl poison soil> compound agent poison soil> K exposed poison soil. Release agent is a new type of dosage form, applied to the soil before the rainy season is not washed by the rain, slow release, the effect is stable, long-lasting. Is the prevention and treatment of pumpkin blight, pepper disease ideal agent.
