In order to study the effect of Anrongle on herbicidal efficacy in peanut field,the peanut Yuhua22 was taken as material,the foliar spray of Anrongle and herbicide mixture was adopted in fields,and herbicidal efficacy,peanut injury and physiological parameters of injuried leaves were investigated and determined. Results showed that the weed control effect was enhanced by Anrongle in the short term. In the later term,the weed control effects of haloxyfop-P-methyl + fluoroglycofen-ethyl( 64. 8 + 45) g/ha and imazapic 72,108 g/ha were enhanced,while those were obviously reduced for quizalofop-P-ethyl + fomesafen to control weeds by Anrongle. A 2—4 level injury and an obvious enhancement in activities of peroxidase( POD),ascorbic acid peroxidase( APX),and catalase( CAT) under lower dose,and in content of soluble sugar under higher dose were presented when treated with quizalofop-P-ethyl + fomesafen. When it was applied with Anrongle,the injury decreased by 1—2 level at lower dose,and no obvious alleviation was investigated at higher dose,the activities of POD,APX and the content of soluble sugar were still significantly enhanced,the CAT activity was dropped to CK level at lower dose and significantly enhanced athigher dose. When treated with haloxyfop-P-methyl + fluoroglycofen-ethyl and imazapic,slight injury was presented in a short-term and 14 days after treating,respectively,the former injury disappeared in 7 days,both the APX activity at higher dose showed a significant enhancement. When Anrongle was added,POD,CAT and APX activities in the former at lower dose were significantly enhanced,APX activity at higher dose was dropped to CK level,in the latter APX activity at higher dose still kept significant enhancement,while other indexes were affected less. Therefore,the change of CAT,APX,POD activities and soluble sugar content might be the physiological reaction for Anrongle adjusting peanut growth under herbicidal stress.
