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.
