Abstract

A field experiment was conducted at Gokuleshwor, Baitadi, Nepal for the management of insect pests of cabbage using synthetic and biological pesticides; Azadirachtin, Cypermethrin, Bacillus thuringiensis var kurstaki, cow urine, Jholmol and Beauveria bassiana to control major insect of cabbage. These treatments were replicated three times in a Randomized Complete Block Design (RCBD) and the effect of different treatments on the population of major damaging insect's (cabbage butterfly, cabbage semi-looper, and cabbage aphids), number of infested plants, number of damaged leaves and number holes in leaves/plant were recorded. The highest larval populations of cabbage butterfly, cabbage aphids and cabbage semi-looper were recorded in control and lowest number was recorded in Cypermethrin. Beauveria bassiana pesticides Racer showed a lower effect than Cow urine and Jholmol in control of semi-looper population. The number of infested plants, damaged leaves and number of holes in leaves/plants were recorded lowest in Cypermethrin. Cabbage head weight and B/C ratio were found lowest in control and highest in Cypermethrin. The insecticides Azadirachtin, Mahashakti (Bacillus thuringiensis var kurstaki, Racer (Beauveria bassiana) and Jholmol would be the best alternative for the eco-friendly management of insect pests of cabbage.
