Abstract

A survey was carried out in vegetable pocket areas of Dhankuta, Baglung, Dhading (midhills) and Bara (terai) Districts with an objective to find out the magnitude of pesticide use in different vegetable crops. A total of 25-35 vegetable farmers were interrogated from each district using semi-structured questionnaires. Efforts were made to gather information on types of vegetable grown, prevalence of insect pests and diseases, extent of damage caused by pests and commonly used pest management methods and materials, and pesticide application frequencies. Data showed that the cabbage, cauliflower, rayo, pea, radish. carrot, eggplants, onion, different kinds of gourds, cucumber etc are the major vegetable crops grown in all surveyed districts. Insect pests were identified as the major cause for
quantitative and qualitative loss in vegetable crops in all the districts. Most damaging insects in the mid-hills in different seasons were aphid, white grub, diamond back moth, cabbage butterfly, red ant, cutworms, flea beetles, fruit fly, whereas eggplant shoot and fruit borer, red pumpkin beetle, fruit fly, cabbage butterfly were found responsible for major damages in terai plains. All the interrogated farmers applied chemical pesticides for the management of these pests. The major chemical pesticides that were used for the management of pests like aphids, diamond back moth and cabbage butterfly were metacid, anumite, cypermethrin etc.
and pesticides often used to manage soil insects (red ant, cut worm, white grub) were chloropyriphos, phorate and malathion dusts. The pesticide frequency of pesticide
application was higher in summer vegetable crops i.e. 10-22 times in a crop season as compared to winter vegetable crops (2-16 times/crop season) in all the four districts.
