Chemical Control

For early grassy weeds and sedges:

·         Spray bispyribac sodium @ 30 g/ha at 8-10 DAE (two-three leaf stage of weeds)

·         Spray Penoxsulam @ 25 g a.i./ha at 10-12 days after transplanting, OR

·         Spray Chlorimuron-ethyl+ metsulfuron-methyl @ 4 g a.i./ha at 7-10 days after transplanting, OR

·         Spray Bensulfuron Methyl + Pretilachlor @ 750 g a.i./ha at 10 DAT ( or two-three leaf stage of weeds), OR

·         Sometimes, the efficacy of herbicides is reduced because of the continuous rain or dry spell following their application. If there are new flashes of grassy weeds, spray fenoxaprop-p-ethyl (60 g/ha) at 25-28 DAE (3-4 leaf stage of weeds), or apply Cyhalofop butyl @ 100 g ai /ha(Late post-emergence)

For mixed population of grassy weeds, sedges, and broadleaved weeds:

·         Tank-mix application of fenoxaprop-p-ethyl + ethoxysulfuron (50+15 g/ha) at 15-20 days after transplanting (2-4 leaf stage of weeds)
