Abstract


Chickpea (Cicer arietinum L.) is an important edible legume of Pakistan. Chickpea blight is a major yield reducing factor in Pakistan. Screening of chickpea advance lines was conducted under control conditions. Out of hundred advance lines, two advance lines were highly resistant, 2 resistant, 6 moderately resistant, 16 susceptible and 74 were found highly susceptible. Four fungicides Dew, Shelter, State and Nativo and three bio-pesticides Vampire, Biosal and Azadirechtin were tested against Ascochyta at different concentrations (500, 250 and 150 ppm) in lab. To evaluate the fungicides and bio-pesticides food poison technique was utilized. Results of the study revealed that Dew at all concentrations (150, 250 and 500 ppm) showed significant reduction in fungal colony diameter. Nativo presented significant reduction of colony at (500 ppm) concentrations while other fungicides Shelter and State did not affect at any concentration. The results of the field condition suggested, that Dew (150ml/acre), Nativo (65gm/acre) and Bio-pesticides product Azadirechtin (500ml/acre) found effective against disease while fungicide Shelter (600gm/acre), State (500gm/acre) and Bio-pesticide product Vampire (1000ml/acre) and Biosal (1000ml/acre) did not control the disease. This study could be helpful to control chickpea blight.
