To evaluate Diuron as a broadleaf weed killer pre sowing of lupins and to evaluate some mixing partners to improve the control of grass weeds.
Diuron appears to be safe when applied pre-sowing of lupins at label rates, as there was no difference in yield between the Simazine alone and Diuron alone treatments.
