Abstract

1-(3,4-dichlorophenyl)-3-methyl-2-pyrrolidinone, technically called BV-201, is one of the recent experimental herbicides available for trial in India. Certain crop plants like Triticum aestivum, Gossypium spp., Arachis hypogaea, Pisum sativum and Solanum tuberosum have already been reported mcderately to highly tolerant to its preemergence application at 1-10 kg. a.i./ha dose (Indofil, nd) The present communication provides information on the response of eleven more field crop plants cultivated in India to this compound. Also certain findings on nature of selectivity of BV-201 to Triticum aestivum have been reported. These two aspects are dealt with here separately.
