Investigate -UK BROME species

Project Detail

Investigate -UK BROME species

The programme of work in this project is structured to provide information on the potential for herbicide resistance evolution in UK brome weeds and identify methods to help slow or prevent resistance evolution of these grasses in UK arable farming. The experimental work will include a UK wide survey of farmers and agronomists to determine the extent of the five main brome species in the UK, identifying areas where these cause major weed problems and where infestations are spreading, this will include interaction with AHDB monitor farms currently struggling with control of bromes (Objective 1). Glasshouse experiments will determine the range in herbicide susceptibility in brome species, and whether bromes are naturally more tolerant to key herbicides and, in conjunction with field surveys, if populations are responding to herbicide selection pressure and becoming less susceptible (Objectives 1 & 2). Potentially resistant populations will be tested and selection experiments will investigate if these brome populations can be easily pushed towards resistance through poor practice in the use of herbicides, to identify herbicide modes of action most at risk of resistance evolution (Objective 2). The best herbicide application timing will be determined to identify strategies to help maintain and improve herbicide control whilst also minimising the risk of resistance evolution (Objective 3). A detailed and extensive knowledge transfer strategy will be developed to disseminate results of the project and communicate an integrated weed management system to help prevent the evolution of herbicide resistance in brome species (Objective 4). The project will be managed by ADAS with collaborative involvement from Rothamsted Research, BASF, Bayer, Dow AgroSciences, and Monsanto. All members of the consortium will be involved with knowledge transfer and, in partnership with WRAG, consistent messages will be agreed and widely communicated, especially to agronomists and farmers.
