Wheat

The farmers of middle Gujarat agro climatic zone growing wheat are recommended to apply premix broad spectrum herbicide clodinafop propargyl (15%) + metsulfuron methyl (1%) WP 64 g/ha or sulfosulfuron (75%) + metsulfuron methyl (5%) WG 32 g/ha (mix in 500 litres of water) as post emergence application (25-30 DAS) or carry out hand weeding at 20 and 40 days after sowing for effective management of complex weed flora and higher net return. No adverse effect of herbicides on succeeding crops was observed.
