Several herbicides are available for weed control in wheat crop. However, one manual weeding and limited herbicide use has been proved more effective than either of the two approaches.
Recommended herbicides include:
Bentazone (2-31) 30 DAS
Clodinafor (0.03 – 0.05) 30 DAS
Chlorsulfuron (0.03 – 0.04) 30 DAS
Fenoxaprop-ethyl (0.075 – 0.01) 30 DAS
Flamprop (1.0 – 2.0) 30 DAS
Isoproturon (0.75 – 1.0) 30 DAS
Metsulfuron-methyl (0.004 – 0.005) 30 DAS
Metoxuxon (1.5 – 2.0) 30 DAS
Pendimethalin (1.0-1.5) 3 DAS
Sulfosulfuron (0.02 – 0.03) 30 DAS
Topic (400 g) 35 DAS
Metasulfuron (0.004) + Isoproturon (0.075) 15 – 20 DAS
Metaxuron (1.5-2.0) 30 DAS
Isoproturon (0.075) + 2, 4 – D (0.40)
Poa annua, an annual grass is becoming problematic in wheat. It has been reported susceptible be sulfonylurea herbicides at 0.28-0.70 kg ha-1 at early active growing stage.
Broad leaved weeds can be managed with 2, 4-D (0.4 kg) 30 DAS. Mixed population of narrow and broad leaved weeds can be controlled with a mixture of Isopoturon and 2, 4-D at recommended doses 35 DAS. For control of weeds in wheat under zero tillage in northwestern and northeastern parts of the country, Sulfosulfuron at 25 g ha-1 or tank mix of Isoproturon and 2, 4-D (750 + 500 g ha-1) should be sprayed after first irrigation. Alternatively, Metibuzin at 210 g ha-1 is equally effective in northeastern areas, when sprayed after first irrigation.
The following herbicides can be used for weed control in intercropping systems:
