摘要

Resistance testing is very important for implementation of control strategies. When testing for resistance of weed populations to herbicides, the development of rapid and reliable bioassays is essential if growers are to be advised of their herbicideoptions in a timely manner. The identification of resistance to ACCase-inhibiting herbicides typically involves applying herbicide to plants grown under controlled conditions although it can involve verification in the field. These methods are expensivein terms of both cost and labor, and it can also take some time before results are known. Alternative seedling assays that involve the determination of either shoot length or root length as growth parameters to discriminate between resistant and susceptible biotypes have been developed for other resistant grass biotypes but not for johnsongrass. The objectives of this study are to determine optimum concentrations for the identification of resistance to clethodim and fluazifop.
