摘要

Groundnut (Arachis hypogaea L.) is most important oilseed crop of India grown during rainy season. The slow initial growth of groundnut and favourable weather conditions during rainy season allow the weeds to grow faster. Season long weed competitionreduces the yield as high as 24 to 70% (Wani et al. 2010). The first three-four weeks of crop growth period are critical for weed control in groundnut (Mulik et al. 2010). During rainy season, effective and economical weed control is not possible throughmanual and mechanical weeding due to unfavourable soil condition and also the unavailability of costly laborers. Herbicides have been accepted as cost-effective tool to manage weeds menace in groundnut. There are number of pre-emergence herbicides suchas oxyfluorfen, fluchloralin, pendimethalin etc. which are being used for weed control in groundnut. However, they often fail to control weeds emerging during early vegetative phase of the crop. Imazethapyr applied as pre-plant incorporated, pre-emergence, early post-emergence or late post-emergence controlled many weeds in groundnut (Wilcut et al. 1995). Imazethapyr is the first herbicide registered in peanut to provide both post-emergence and residual control of many problem weeds (Grichar and Sestak2000). Therefore, the present study was undertaken to evaluate the bio-efficacy of imazethapyr 10 per cent SL, as early post-emergence against important weeds of groundnut under agro-climatic condition of Varanasi in Eastern Uttar Pradesh.
