A field experiment was conducted during rabi 2008 on sandy loam soils of S. V. Agricultural College, Tirupati to study the effect of integrated weed management with low volume herbicides on growth and yield of sweet corn. The experiment consisted of 10 treatments. Growth parameters, yield attributes and green cob and green fodder yield were highest with hand weeding twice at 20 and 40 DAS (T9), which were on par with sulfosulfuron+imazethapyr as pre-emergence with hand weeding at 40 DAS (T6). Net returns and benefit: cost ratio were highest with sulfosulfuron @ 15 g a. i./ha+imazethapyr @ 25 g a. i./ha as pre-emergence with hand weeding at 40 DAS (T6), which were, however, on par with hand weeding twice at 20 and 40 DAS (T9).
