Successful black grass control

The best time to really get on top of black grass is in the Oilseed rape crop rotation. Followed by good soil & seedbed management of the next crop.
CO2 reduction by min till following an osr crop where control has been poor, is fatal.
Good soil CO2 release creates good germination of all seeds allowing us to get control. Reducing C02 reduces germination of black grass seeds and crop.
Soil management is key.
