Bioefficacy and phytotoxicity of new herbicide formulations against weeks in soybean (Glycine max)

A:PS

The bioefficacy of Pursuit Plus [imazethapyr + pendimethalin] (2.5, 3.0, and 6.0 litres/ha) against the weeds (mainly Cyperus rotundus, Cynodon dactylon, Panicum ischami [Digitaria ischaemum], Digitaria sanguinalis, Parthenium hysterophorus, Acalypha indica, Achyranthes aspera, Acanthospermum hispidum, Corchorus acutangulus, and Euphorbia geniculata) of soyabean (Glycine max) was evaluated in Rahuri, Maharashtra, India, during the rainy seasons of 1999 and 2000. The pre-plant incorporation of Pursuit Plus at 2.5 litres/ha was most effective in the suppression of weed growth and in the improvement of soyabean grain yield. Hand weeding at 15 and 30 days after sowing, Pursuit Plus at 2.5 and 3 litres/ha, and alachlor at 2 kg/ha were equally effective in the enhancement soyabean grain yield and in the reduction of weed density and dry matter. The application of Pursuit Plus 32% EC at higher rates reduced seed germination and crop yield. Herbicide toxicity on the succeeding winter potato (Solanum tuberosum) was not significant.
