| Abstract | Cabbage is a cash crop among the common vegetables in Nepal, which heavily suffers from insect pests. Pesticides are largely used, which often pollute the environment and affect the health of the people. Therefore, this study was conducted to select a suitable pest control method to avoid the negative effects of pesticides. Field survey conducted in both Kabhre and Jumla districts revealed that major pests in cabbage were cabbage butterfly, diamondback moth, tobacco caterpillar, aphids and flea beetle. Majority of the farmers of the mid-hills depend on chemical pesticides, where as those in high-hills prefer non-pesticidal methods for pest control. The farmers in mid-hills apply pesticides on a schedule, but most of the farmers in high-hills always examine the crop for pests before spraying pesticides. A field experiment revealed that Bacillus thuringiensis was more effective on caterpillars and larvae, nimbecidine was more effective against aphids and flea beetles, and both did not harm natural enemies. Malathion affected all insects pest, except tobacco caterpillar, and all natural enemies. The cabbage yield under Bacillus thuringiensis, nimbecidine, malathion and control were 39, 35, 32, and 25 mt/ha, respectively, but the differences among pest control methods were insignificant. |
