烯酰吗啉等药剂分别与嘧菌酯混配对葡萄霜霉病的联合毒力测定
Allied Toxicity Determination of Azoxystrobin and Polyhexamethylene Biguanidine Hydrochloride Combined with Dimethomorph on Plasmopara viticola
摘要
Abstract
This study was to clarify the co -effects of dimethomorph and polyhexamethylene biguanidine hydrochloride (PHMB)with azoxystrobin on P.viticola.The toxicities of the 3 single fungicides,the mixtures of PHMB and azoxystrobin at 6 different ratios,and the mixtures of dimethomorph and azoxystrobin at 5 differ-ent ratios on P.viticola were tested by in vitro leaf disc assay.The results showed that the EC50 of azoxystrob-in,PHMB and dimethomorph were 2.010,64.961 and 2.722 mg·L -1 ,respectively.The 6 different matc-hing ratios of PHMB and azoxystrobin including 15∶1,12∶1,9∶1,6∶1,3∶1 and 1∶1,had synergistic effect on P.viticola,and the ratio of (6 ~9)∶1 had the larger SR value and the strongest synergistic effect.Similar-ily,the 5 different matching ratios of dimethomorph and azoxystrobin including 4∶6,5∶5,6∶4,7∶3 and 8∶2 also had the synergistic effect on P.viticola,and the ratio of 6∶4 had the SR value as 1.82 and the strongest synergistic effect.关键词
