Abstract
The haphazard and unsystematic pesticide use has marred the existing conventional agriculture system of Nepal and Nepalese agriculture is also impinged from its impact to a great extent. Pesticide use being less tedious, more economic, and easy to use in one hand and high import of the pesticides through pervious border on the other has made farmers to embrace pesticide dependent farming practices more often. The study is focused on assessing the pesticide use status of the country, import and formulation, pesticide residue on agricultural produces from few years back to present, and the dire economy supposed to be forecasted in Nepalese agriculture in near future as a result of these scenarios. The chemical pesticides were imported in the country during 1950s for the first time. The national average of pesticide use is 396gm a.i/ha. The terai region of the country is hotspot of excessive pesticide use (995 gm a.i/ha). Among the pesticides used in agricultural produces, vegetables dominate the most (90%). The highest percentage share of the pesticide on total pesticide use is fungicide (49%). Reviewing the trend of 20 years scenario of pesticide import from 1997/98 to 2017/18, the result seems transcending surprisingly. The increment of pesticide residue in agricultural produce such as fruits and vegetables is challenging the human and animal health as well as encumbering the goal to food security and sustainability. This scenario directs the need of healthy agricultural practices to abate the impacts of excessive pesticide use so as to ensure food and nutritional security and agricultural sustainability.
Highlights
Pesticides are substances or mixture of substance deliberately used for preventing, eradicating, repelling or minimizing the damage of any pest (Eldridge, 2008)
Pesticide application is practiced in agricultural crops by majority of the commercial farmers of the third world nations including Nepal and they grant pesticide as panacea to the infirmities created by insects, diseases and weeds in agriculture crops, vegetables
Easy to use and handle, minimum awareness level and more economic are probably the major reasons for choosing pesticides over bio-control farming in Nepal Among the various pesticides, fungicide is the major one used in the context of our country followed by insecticide
Summary
Pesticides are substances or mixture of substance deliberately used for preventing, eradicating, repelling or minimizing the damage of any pest (Eldridge, 2008). Pesticide application is practiced in agricultural crops by majority of the commercial farmers of the third world nations including Nepal and they grant pesticide as panacea to the infirmities created by insects, diseases and weeds in agriculture crops, vegetables. It has challenged the existence of non-target organisms in the nature (Atreya, et al, 2011). The speculation of “if little is good, a more will be better” regarding pesticide has created havoc in human and other life forms hurdling the goal to sustainable agriculture
