Abstract
The production of cabbage is highly influenced by the attack of insect pests and the infestation of insects is higher in the summer season. Among the insect pests, Lepidopterous insects play a vital role in the decreased production of cabbage. The response of major Lepidopterous insects to some commonly used botanicals was investigated under the present study on summer cabbage. Seven treatments, viz. T1 (Mahogany seed kernel extract @ 3.0 ml/L of water); T2 (Tobacco leaf extract @ 3.0 ml/L of water); T3 (Garlic extract @ 3.0 ml/L of water); T4 (Neem leaf extract @ 3.0 ml/L of water); T5 (Neem seed kernel extract @ 3.0 ml/L of water); T6 (Neem oil @ 3.0 ml/L of water) and T7 (untreated control) were used and applied at seven days interval. Among the management practices, the lowest mean infestation of cabbage leaf by semi-looper (4.79 leaves/5 plants), cabbage caterpillar (6.25 leaves/5 plants) and diamondback moth larvae (4.39 leaves/5 plants) was found in T6 that reduced highest leaf infestation over control (59.40%, 61.73%, and 68.03% respectively); whereas the highest mean infestation by semi-looper (11.80 leaves/5 plants), cabbage caterpillar (16.33 leaves/5 plants) and diamondback moth larvae (13.73 leaves/5 plants) was recorded in T7. The highest diameter and height of cabbage head was found in T6 (21.58 cm and 10.23 cm respectively); whereas the lowest was found in T7 (14.87 cm and 7.10 cm respectively). The highest single head weight (1.46 kg) was found in T6 that provided the highest total yield (36.50 t ha-1). On the contrary, the lowest single head weight and total yield were recorded in T7 (0.94 kg and 23.08 t ha-1 respectively). So, Lepidopterous insects of summer cabbage could be managed by using botanicals judiciously that would be safe for the health concerns of farmers as well as the consumers.
Key Words: Biorational approach, Ecofriendly management, Food safety, Offseason cabbage and Organic vegetable
