Efficacy of Bio-rational insecticides against Perilla leaf moth on sweet basil (Ocimum basilicum)

The present study was carried out during kharif 2016–18 at Agronomy Farm, Rajasthan College of Agriculture, MPUAT, Udaipur. Perilla leaf moth, Pyrausta panopealis Walker (Lepidoptera: Pyralidae) is an important and major insect pest sweet basil, therefore, ecofriendly bio-rational insecticides were evaluated against perilla moth in the experiment. experiment laid uniformly sized plots measuring 12 m2 (4 m × 3 m) Randomized Block Design containing six treatments four replications. treatment schedule comprised two sprayings, first 15 days after transplanting second 45 transplanting. different treatments, viz. Azadirachta indica oil (3%) followed by Bacillus thuringiensis (1.5 kg/ha); NSKE (5%) Spinosad 45SC (150 ml/ha); Azadirachtin 1500 ppm (1%) Lambda Cyhalothrin 4.9 CS (1 L/ha); Pongamia pinnata Cypermethrin 10 EC (0.005%); Nicotine Sulfate 40 S (0.02%) Deltamethrin 2.8 (0.015%) Untreated control. Among most effective 3, 5 7 spray. After spray SC ml/ha) superior days; whereas, kg/ha) least both subsequent years.
