Herbicide-resistant black-grass has been confirmed in over 30 counties in England, with the eastern and south-eastern counties being particularly badly affected. Monitoring the prevalence of black-grass was introduced into the Defra Winter Wheat Pest and Disease Surveys in 2012 following reports of significant problems in controlling black-grass weeds in wheat crops. Research shows that a number of cultural methods can reduce black-grass incidence including use of ploughing, rotation and delayed drilling. The Agriculture and Horticulture Development Board’s (AHDB) Cereals and Oilseeds Division has brought together a range of advice on its website to help farmers tackle the problem of black-grass.
