Abstract

An extensive survey was conducted in the major carrot growing blocks in The Nilgiris district of Tamil Nadu to assess the pesticide usage pattern in carrot agro-ecosystem. The results revealed that the farmers were used 19 different synthetic chemical insecticides on carrot for the management of different pests. Most frequently sprayed chemical groups were neonicotinoids, diamides, and organophosphates. Among the insecticides, imidacloprid (93%), chlorantraniliprole (86%), lambdacyhalothrin (80%), and cyantraniliprole (75%) were sprayed by most of the farmers. Results revealed that, 72. 22 percent of the carrot growers were marginal farmers, 66.67 per cent of the farmers using power sprayer for spraying insecticides, 75.56 and 85.56 per cent of the farmers spraying 7 to 10 number of insecticides in 3 to 4 days interval within the cropping period of 110 days. The knowledge of farmers on personal safety measures during spraying was very limited moreover, their spraying pattern also did not alternate with different pesticide groups, which may result in the development of resistance and a higher dose of the same insecticide. The frequency of spraying reveals massive damping of synthetic pesticides in the carrot ecosystem.

Conclusion

The results of the present study revealed the pesticide usage pattern in the carrot in The Nilgiris district. Insecticides like imidacloprid, Chlorantraniliprole, lambda cyhalothrin and cyantraniliprole were extensively used by the farmers to control carrot pests. Famer’s knowledge on personal protection while spraying, source of information on pesticide, disposal of pesticide container was very less. Hence intervention of the government organizations viz., Department of Horticulture, Krishi Vigyan Kendra and ICAR institutes is highly essential to educate the farmers on safe handling of pesticides, organic and natural farming systems to overcome food safety issues.
