Abstract:
The Field experiment was conducted during Kharif season 2015 at Research Cum Instructional farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur C.G. to evaluate the quinchlorac herbicide against weeds in transplanted rice. Ten weed control treatments were laid out in randomized block design with three replications. The result revealed that the major weed species in experimental site were Cyperus iria L, Cyanotis axillaris L, Alternanthera triandra L, Echinochloa colona L, Ischaemum rugosum Salisbury, and Caesulia axillaris Roxb. The highest gross return, net return and benefit cost ratio was obtained under treatment quinchlorac 250 g/l SC @ 250 g ha^-1 + bispyribac sodium (10% SC) @ 20 g ha^-1 (T₅) followed by quinchlorac 250 g/l SC @ 250 g ha^-1 + ethoxysulfuron (15% WP) @ 15 g ha-1 (T₄) and lowest gross return was noted under control (T₁₀).
