摘 要:
采用室内离体平皿法测定了12种杀菌剂对黄瓜枯萎病的抑菌作用以及福星、世高和福美双不同组分配比的联合毒力。结果表明：40％福星EC、10％世高DG和50％福美双DC对黄瓜枯萎病菌具有优异的抑菌作用，其EC50分别为0．0998μg／mL,02669μg／mL和0．3795μg／mL，3个混配制剂对黄瓜枯萎病的共毒系数分别为699．9、241．9和173．1。福星·世高配比（福星：世高为1：49）对黄瓜枯萎病菌的增效程度高于福美双·福星配比（福美双：福星为47：3）和福美双·世高配比（福美双：世高为42：8）。[著者文摘]

Abstract:
Toxicity of 12 kinds of fungicides, and mixtures of 10% fluquinconazole-difenoconazole and 50% thiram-fluquinconazole and 50% thiram -difenoconazole against Fusarium wilt of cucumber were determined in laboratory by means of pertidish testing. The results showed that fluquinconazole and difenoconazole and thiram provided a good control for Fusarium wilt of cucumber with EC50 of 0. 0998 μg/mL,0. 2669 μg/mL,0. 3795 μg/mL. The syntoxicity coefficient of fluquinconazole and difenoconazole （1 ： 49,w/w）and thiram and fluquinconazole（47 ： 3） and thiram and difenoconazole（42 ： 8） were 699.9 and 241.9 and 173.1 . The activity of fluquinconazole and difenoconazole wase higer than that thiram-fluquinconazole and thiram-difenoconazole to Fusarium wilt of cucumber.[著者文摘]
