Abstract:
Clusterbean (Cyamopsis tetragonoloba L.) is an important crop of Rajasthan. Insect pests are the major constraints in the production and productivity of clusterbean. On this basis, an experiment was laid out with the view to find out the possibility of minimum incidence of insect pests during Kharif 2015 and 2017. Eight different treatment combinations along with untreated control were laid out in randomized block design with three replications. Minimum pooled PDI(10.48), minimum aphid incidence (0.7) and minimum jassid incidence (0.87) was achieved with the treatment T7 (Seed soaking for 30 minutes with streptocycline @ 500 ppm + seed dressing with carbendazim @ 2 g/kg) + (Seed treatment with fipronil 5% SC @ 4 ml/kg seed) + (Foliar spray with streptocycline @ 250 ppm + copper hydroxide @ 0.2% at 15 days interval) + (Foliar spray with Thiomethoxam 25 WG @ 0.3 g/liter followed by Acetamipride 20 sp @ 0.2 g/liter at 15 days interval).
