Abstract | Commercialization of agriculture along with climatic variations has led to increased pest problems and outbreaks. Vegetable growers prefer to use easily available pesticides for managing field pests that has further increased pest resistance, secondary pest outbreaks, the cost of production, and environmental degradation and health hazards. Against the backdrop of pesticide impacts, a field survey was conducted by consulting 60 commercial vegetable producers in pocket areas of Makawanpur and Parsa district, Nepal. The study was conducted to analyze the field pest problems in vegetables and the use of pesticides for their management. Among the ten problems the producers mentioned, pest-diseases, reliability of seed quality, irrigation and watering, drought and climatic changes were major four problems. To manage the pests and diseases, farmers were using higher number of sprays and heavier doses of pesticide in major vegetables. The pesticides are being inefficient as 91.66% of the respondents mentioned pest and disease problem is increasing over the years. The highest number of pesticides sprays was found in brinjal (23.6±5.44 sprays), followed by sweet pepper (17.34±3.95), tomato (13.63±6.75), ladies finger (10.28±2.37), cucumber (9.68±6.90), cowpea (8.61±4.54) and bitter gourd (8±4.65). Similar pattern was observed in the quantity of active ingredients (a.i.) sprayed in different vegetables. Brinjal received the highest amount of a.i. (15.93±3.67 kilogram per hectare) followed by sweet pepper (11.71±2.67), tomato (9.20±4.56), lady's finger (6.94±1.86), cucumber (6.54±4.66), cowpea (5.82±3.06) and bitter gourd (5.40±3.14) during a single crop growing season. Eco-friendly methods need to have devised for more climate resilient plant protection measures. |
