In wheat field, common weeds are Chenopodium album L. And Cyperus rotundus L. Wheat crop should be kept absolutely free from weeds at least up to 45 days of sowing. For this purpose, one hand weeding is done after 3 to 4 weeks of sowing. However, now a days, this operation becomes difficult (costly) due to hike in labour charges and unavailability of sufficient labour in time. The only way to control weeds effectively is to use selective herbicide like Pendimethalin @ 0.5 to 1.0 kg/ha in 600 l of water as pre-emergence. If spray is delayed, emergence of seeds adversely affected. If it is not possible to apply weedicide at the time of sowing, 2-4-D sodium salt @ 960 g/ha in north Gujarat or 750 g/ha in Middle Gujarat in 600 l of water should also be sprayed at about 30 to 35 DAS. Care should be taken that 2-4-D should be sprayed in between the time of two irrigations in between rows only.
