Abstract

Herbicide-resistant populations of Alopecurus myosuroides Huds (black-grass) have become widespread throughout the UK since the early 1980s. Clear evidence suggests that more than one resistance mechanism exists, and glutathione S-transferases (GSTs) have been implicated in resistance due to enhanced metabolism. This study reports the determination of GST activity in fourUK black-grass populations from field sites situated in the East Midlands. Data demonstrate that, as untreated plants in the field mature, there is an accompanying natural elevation of GST activity with natural environmentalchanges from winter to spring. We speculate that this endogenous change inenzyme activity with plant development in the field contributes to reducedefficacy of some graminicides applied in the spring. These observations are discussed in relation to predicting herbicide efficacy to achieve maximumcontrol of this important grass weed. (C) 2001 Society of Chemical Industry.
