Getting the best out of grass herbicides pre sowing of wheat locations
Aims

To evaluate how incorporation method impacts on the emergence of annual ryegrass from the furrow wall for various pre sowing grass herbicide mixtures in wheat.

Key messages

The double incorporation of trifluralin method is designed to minimise the number of ryegrass that emerge from the edge of the furrow wall. However, there was no effect of incorporation with rolling harrows, or the snake chian on ryegrass density in the furrow of this trial.
