作者于1990年应用复方代森锌乳粉,在兰州进行了番茄早疫病[Alternaria solani (Ell.et Mart)]、番茄叶霉病(Cladosporium fulvum Cooke)防治试验。结果表明.应用65%复方代森锌乳粉300～500倍,从发现早疫病发病开始喷药,间隔12天喷1次,共喷3次。防治番茄早疫病的效果为85.12～91.88%;防治叶霉病的效果为88.55～97.21%。每亩番茄比对照增产469.35～1095.16公斤,增产效果达10.62～24.78%。大棚小型示范,应用复方代森锌乳粉400倍,喷布2～3次,防治两种叶斑病也均得到良好的防病增产效果,对番茄又很安全。
In 1990, the author applied the compound desense zinc powder to conduct the prevention and control test of Alternaria solani (Ell.et Mart) and Cladosporium fulvum cooke in Lanzhou. The results show that the application of 65% compound dexmedeen milk powder 300 ~ 500 times, from the onset of early blight found spraying, spray 12 times an interval, a total of 3 times. The control effect of tomato early blight was 85.12 ~ 91.88%. The control effect of leaf mold was 88.55 ~ 97.21%. The yield per mu of tomato increased 469.35 ~ 1095.16 kg compared with the control, and the yield increase reached 10.62 ~ 24.78%. Small demonstration of greenhouses, the application of compound desense milk powder 400 times, spray 2 to 3 times, prevention and treatment of two leaf spot disease also have a good anti-disease and yield, tomato is very safe.
