A study was carried out in the district (two taluks) of Erode of Tamil Nadu; India to ascertain the variety of pesticides was used in the Paddy (Oryza sativa L.) ecosystem. One representing the IPM adopter and other representing non-IPM adopter were randomly selected from each taluk. The awareness about the IPM farm practices was very less in non-IPM farmers compared to IPM paddy growers. Important precautions like using masks and gloves were followed either by very few farmers. Use of carbofuran was 1.598 kg/ha in IPM and 3.131kg ha-1 in Non-IPM paddy growing sample farms. The highly hazardous chemical like phorate was used only in Non-IPM paddy at the rate of 2.5 kg ha-1. The net return per ha was ₹.9815.62 in IPM and ₹.6617.15 in non-IPM paddy farms. Average cost of pesticides in IPM paddy was only ₹.212.42 and it was ₹.769.48 ha-1 in Non-IPM paddy. Eco-friendly bio control agents like Bacillus thuringiensis and Azardirctin were applied only in IPM paddy growing sample farms. The number of pesticides used and the application rate were less in IPM paddy compared to Non-IPM paddy. The Environmental Impact Quotient (EIQ) value of usage of chemicals in IPM paddy was less at 28.40 compared to Non-IPM paddy at 40.26. Most common health problems due to the use of pesticides reported by the sample respondents, were tiredness (58.33 %) followed by head ache (45.00 %). Allergic dermatitis and body pain were reported by 31.67 and 21.67 % of the sample farmers, respectively. Constraints in IPM adoption in paddy cultivation was high wage labour, non-availability of labour, lack of IPM inputs such as; Azospirlillum, Tricoderma sp., In Non -IPM paddy sample growers expressed lack of confidence in IPM measures.
