Controlling black grass

The Lower Saxony Chamber of Agriculture created a trial to find out whether a harrow can improve the efficiency of herbicides against black grass.

The result shows that the TREFFLER harrow can do it. Not only was the efficiency of the herbicide increased from 89% to 99%, but the yield and thus market performance also increased when the TREFFLER harrow was used. The improved herbicide performance also reduces the multiplication potential of resistant black grass populations.
