Why control weeds early?

Early season weed control is essential for successful maize crop establishment. Weed competition for light, moisture and nutrients can seriously rob the crop’s yield potential from early days.
When is the point of no return?

Weeds left in the crop for longer than 10 days after crop emergence will begin to reduce yields. More yield will be lost for each day that the weeds remain.
