代森锰锌对高产夏玉米登海661褐斑病空间分布及产量影响
EFFECT OF MANCOZEB ON THE SPATIAL DISTRIBUTION OF CORN BROWN SPOT AND THE YIELD TO HIGH YIELD SUMMER MAIZE
摘要
Abstract
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.关键词
