Herbicide Use in Game Cover Crops
Just like when growing a commercial crop such as wheat or oilseed rape there are many variable factors that influence the levels of success you will experience in establishing your game cover crop or wild bird seed mixture. These can include grazing by birds or rabbits, the weather and ground/soil conditions. However there are things you can do to achieve a good crop and one of these is reducing the weed population, to ensure the best possible chance of establishment and so now is the time to start planning your strategy.
Several different crop species are often established in the same place year on year to provide food and shelter for game birds or to promote wildlife and biodiversity. This itself complicates and limits the choice of herbicides available to the grower for weed control.
Corteva Agriscience are proud to introduce our portfolio of products that have approval in game cover crops. These are products that all arable farmers will be very familiar with and are widely used in many crop scenarios which are totally transferable into game cover situations. The products which have Extensions of Authorisation for Minor Use (EAMU) approval are:
These products can be used in a wide range of game cover crop species and will control the weeds that are most harmful to establishment.
To see which products can be used with which cover crops and the weeds which they will control, please refer to the table below or download the GameCover Topic Sheet:
