Study on Major Pesticides and Fertilizers used in Nepal

Abstract

The data of Nepal Government shows that nine major pesticides groups with seven subgroups of Insecticides were imported from the year 1997 to 2003. The pesticide use amounts to 142 g/ha which is low compared to other counties. The highest pesticides quantity imported & quantity consumed from the 2056/57 (1999) to 2060/061(2003) were fungicides, bactericides, acaricides & seed treatment. group. For the year 2056/57 (1999) & 2057/58(2000), no import & consumption of biopesticides were done but from the year 2058/59(2001) to 2060/061(2003) no import & consumption of plant regulators was done. The various types of pesticides with 306 trade names and 71 technical names are registered / enlisted and used in Nepal which includes Insecticides, Fungicides, Herbicides, Rodenticides, Acaricides and Others. Moreover, twelve types of pesticides are band in Nepal for its import and use. Similarly, the demand of fertilizers were increased from 1997/98 to 2001/02 and then decreased dramatically with high amount from 2001/02 to 2002/03 and since then again it again increased up to 204/05. This trend is same for Urea and Diammonium Phoshphate whereas Murate of Potash is increasing from 1997/98 to 2004/04. Seven types of fertilizers are being used in Nepal viz. Urea, Diammonium Phosphate (DAP), Murate of Potash (MOP), Ammonium Sulphate (AS), Single Super Phosphate (SSP), Ammonium Phosphate Sulphate (APS) and NPK. These are imported by Public institution like Agricultural Input Corporation (AIC) , Private Institutions and also donated/granted by the Government of Japan called as 2KR (Two Kenny Round). The import of fertilizers shows irregular trend. The import of fertilizers was highest in 1998/99 which amounted to 219038 metric ton and since then it decreased although there showed fluctuations. The distribution of fertilizers was increase from 1997/98 and reached highest in the year 2002/03 and since then it started decreasing. Similarly, the fertilizer consumption was highest in the year 1994/95 which was 30.4kg/ha which declined since then and showed fluctuation. The fertilizer consumption is regularly decreasing in the recent years from the year 2002/03.
