Managing weeds in maize

Avoid loss: go early

All weeds should be removed at the earliest opportunity, ideally before they reach 10 cm high and before the crop is at the 4 leaf stage. Prioritise fields with the highest weed population densities, difficult to control weeds and any slow growing crops first.

Based on numerous trials the latest stage of weed removal without yield damage should be no later than 4 leaf stage of the maize crop.
