摘  要：
黄瓜黑星病近年来已成为吉林省黄瓜生产上的严重病害。1984～1986年在吉林省的9个主要城市的调查中发现此病已普遍发生。发病严重的温室、大棚或露地黄瓜损失达70％以上。病情在3～4级的病瓜,其重量可降低50％以上。1987～1988年又在海南岛发现此病为害。经过3年的药剂试验表明多菌灵防效最好,1985、1986、1987年的平均防效分别为87.38％、83.09％、89.64％;其次是甲基托布津,1985、1986年的平均防效分别为82.69％和72.2％。1986年各地小区试验中多菌灵和甲基托布津分别平均增产53.1％和35.27％。多菌灵加其他防治霜霉病的药剂混用并不影响其防治黑星病的效果,且均有增产效果。
