Weed management in garlic (Allium sativum L.)

Abstract

Three herbicides (Pendimethalin @ 0.75 and 1.0 kg/ha, Oxyfluorfen @ 0.125 and 0.150 kg/ha and Quizalofop ethyl @ 0.025 and 0.50 kg/ha) alone and in combinations were compared with weedy check (untreated) and weed free check during rabi season 2015-16 for controlling weeds in garlic crop. The herbicide treatment T10 - Oxyfluorfen 0.150 kg/ha + Quizalofop ethyl 0.050 kg/ha found significantly superior and recorded minimum weed density at stages of crop growth, dry weight and yield (155.60 q/ha). Similarly the same herbicide treatment registered the maximum Weed control efficiency (84.17%), Herbicide efficiency index (5.41%), Weed management index (0.91%), Gross monetary returns and net monetary returns as well as highest B:C ratio (2.70). The minimum weed index (5.12%) and agronomic management index (1.11%) were noticed in same herbicide treatment. This clearly indicates that the application of Oxyfluorfen 0.150 kg/ha + Quizalofop ethyl 0.050 kg/ha as post emergence found effective in controlling weeds and increasing bulb yield of garlic crop.
