Abstract:

A field experiment was conducted during the kharif 2021 at Instructional-cum-Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh to evaluate new molecules of on weed control in direct seeded rice. BAS 625 04 H is a member of Cyclohexenone group, post emergence herbicide used for annual grassy weeds in various field crops. Post-emergence (POE) application of BAS 625 04 H @ 75 g a.i. ha-1 with MSO adjuvant gave lower total weed density, weed dry weight and higher weed control efficiency at all the intervals which was at par with Cyhalofop butyl 10 % EC and BAS 625 04 H @ 55 g a.i. ha-1 with MSO adjuvant. Among the different doses of BAS 625 04 H higher grain yield and straw yield recorded under BAS 625 04 H @ 75 g a.i. ha-1 with MSO adjuvant and @ 55 g a.i. ha-1 with MSO adjuvant. Untreated control accounted for lower grain yield, higher weed density and dry weight due to heavy competition of weeds for nutrients, space and light.
