- Abstract
The study aims to determine dose requirements of herbicides for controlling A. tenuifolius on farmer's field in chickpea during 2005-06 and 2006-07. Five herbicides: pendimethalin, s-metolachlor, fenoxaprop-p-ethyl, MCPA and isoproturon with four doses were studied in the trials. MCPA produced phytotoxic effect on weed and crop and completely inhibited crop and weed growth. Isoproturon was less effective on A. tenuifolius with less phytoxicity on crop. Best seed yield was recorded in pre-emergence herbicides (1164 and 1150 kg ha-1) at high dose as compared to fenoxaproppethyl (1088 kg ha-1) . Next year (2006-2007) again the same herbicides were tested while MCPA due to its phytotoxicity on crop was replaced by clodinafop propargyl (post-emergence). Almost similar results were recorded with the only difference of herbicides clodinafop propargyl. The best seed yield of 1109 kg ha-1 was recorded each for pendimethalin and s-metolachlor which was however, statistically similar with fenoxaprop-p-ethyl (1107 kg ha-1). Lower (½X) and 1X doses of post-emergence herbicides produced good results as compared to 1.5X, while pre-emergence herbicide was effective at 1.5X dose.
