RESPONSE OF CHICKPEA (Cicer arietinum) AND Euphorbia dracunculoides TO PRE AND POST-EMERGENCE HERBICIDES

A pot trial was conducted at the agronomic research farm,university of agriculture, faisalabad, pakistan in 2007-08 to evaluate nine pre and post emergence herbicides.subsequently, a field experiment was conducted during winter 2008-09 to study the effect of herbicides selected from pot trialon weeds and growth and yield of chickpea at farmer’s field indistrict bhakar, punjab, pakistan. stomp-455cs at 1875,2000ml ha-1, dualgold-960 ec at 1500 ml ha-1, buctril super-60 ec at 1125 ml ha-1, aim-40 df at 75 g ha-1, starane-m 60ec at 1125 ml ha-1, 1250 ml ha-1, sencor-70 wdg at 375 and top grow-90 wdg at 700 g ha-1 were applied as pre-emergence spray while aim-40 df at 75 g ha-1 was also applied as pre emergences and mix broadcast application. basagran-48 sl at1500 ml ha-1 was applied as a post-emergence spray. the results revealed that all the herbicides (except aim-40 df)applied as sand mixed broadcast application caused 100% cropmortality in pot trial. generally control of euphorbiadracunculoides was 30 to 92%. in field trial all herbicides except dualgold-960 ec gave 82 to 100% control of asphodelustenuifolius and control of carthamus oxycantha ranging from 75to 100% with all herbicides except dualgold-960 ec, starane-m60ec at 1125 ml ha-1 both as pre-emergence spray and aim-40 df at 75 g ha-1 as sand mix broadcast application. whereas,control of euphorbia dracunculoides with these herbicides except dualgold-960 ec was 72 to 100%. basagran-48 sl at1500 ml ha-1 caused 100% crop mortality followed by 79, 46 and 43% in sencor-70 wdg at 375 g ha-1, starane-m60 ec at1125ml ha-1 and 1250 ml ha-1, respectively. pre-emergence application of stomp-455 cs, aim-40 df and top grow-90 wdg each as pre-emergence spray recorded more than 40% increase in grain yield of chickpea over check.
