Efficacy Of Different Insecticides Against Gram Pod Borer On Chickpea (Cicer arietinum L.)

The insecticides Proclaim, Radiant and Jatara were applied thrice at the interval of 15 and 20 days of second and third spray, respectively. The results showed that all three insecticides performed well in reducing pest population. However, Proclaim gave best results against gram pod borer. The overall mean population of Helicoverpa armigera 0.36, 0.44 and 0.49 per plant was recorded in the plots treated with Proclaim, Radiant and Jatara, respectively as compared to control plot (1.23 larvae per plant) during the first spray. During second spray the overall mean population of H. armigera 0.33, 0.51 and 0.56 per plant was recorded in the plots treated with Proclaim, Radiant and Jatara, respectively as compared to control plot (2.21 larvae per plant). Whereas, during third spray the overall mean population of H. armigera 0.29, 0.44 and 0.48 per plant was recorded in the plots treated with Proclaim, Radiant and Jatara, respectively as compared to control plot (2.68 larvae per plant). All insecticides performed well up to 72 hours interval. ANOVA results showed significant difference between treatments and LSD test showed that efficacy of different insecticides remained non-significant at 24, 48 and 72 hours.
