Shortage of farm labour triggered by migration and social welfare schemes such as National Rural Employment Guarantee Act (NREGA) is resulting in increasing usage of herbicides in the country. Also the rising labour wage component in the total cost of cultivation is aiding such a trend. Companies including Monsanto India, Dhanuka Agritech, Excel Crop Care Ltd and state-run Hindustan Insecticides Ltd (HIL) have seen a rise in herbicide sales in the past couple of years.
