Aims: The main aim of this study is to examine the growth rate of consumption of pesticides in India and Tamil Nadu. Place and Duration of Study: The study was carried out using the time series data on pesticide consumption collected from secondary sources from 1990 to 2020 for India and for Tamil Nadu, the data were collected from 2011 to 2021. Methodology: The compound annual growth rate is used to calculate the growth rate of consumption of pesticides. The data is segmented for every 10 years and decadal growth rate was also examined. Results: The overall compound annual growth rate of pesticide consumption is negative(-0.44 per cent) and the decadal average was found to be -5.27%, -0.73% and 1.81% for the decades 1990-2000, 2001-2010 and 2011-2020 respectively for India. The growth rate for different types of pesticides was found to be declining (-2.26 per cent) for insecticides, however it is increasing for fungicides (2.65 per cent) and herbicides (0.99 per cent). CAGR indicates that there is no change in growth of pesticide consumption in Tamil Nadu. Conclusion: The trend in the pesticide use has been decreasing over the period and it shows that the total quantity of pesticides used in the country has been continuously decreasing which is a healthy sign for the environment. It may due to increase in the area of organic farming, practices like IPM  and increase in the use of biopesticides.
