A review on management of weeds in maize (Zea mays L.)

Weeds constituent one of the major economic important problem for maize growers and it can reduce yield up to 86 per cent. The magnitude of losses largely depends upon the composition of weed flora, period of crop-weed competition and its intensity. The highest weed control efficiency with lowest weed density and weed dry weight was noted in pre-emergence application of atrazine @ 1.0 kg a.i. ha-1 followed by (fb) one hand weeding (HW) at 30 DAS.
