摘　　要：通过田间小区试验,研究了代森锰锌拌种以及5叶期、8叶期、9叶期茎叶喷雾等不同处理方式对玉米褐斑病空间分布的影响和控制效果。结果表明：代森锰锌在玉米5~9叶期喷雾处理能有效抑制玉米褐斑病由下部叶片向上部叶片的扩展,尤其是8叶期喷雾处理,可以将发病叶片控制在第6展开叶以内,防治效果达88.9%,增产率达31.5%,为防治玉米褐斑病的最佳用药时期。Effect of coating seeds with mancozeb and spraying at 5 leaf stage,8 leaf stage and 9 leaf stage on the and the control of corn brown spot（Physoderma maydis） were studied with completely randomized design.The results showed that it can effectively suppress the spreading of corn brown spot from bottom leaves to upper leaves by spraying mancozeb at 5 to 9 leaf stage,and the incidence blades were controlled by the first six leaves through spraying at 8 leaf stage,the control of which particularly achieved 88.9%,and the yield was increased by 31.5%,so the 8th leaf stage is the best medication period to fight corn brown spot.
