Abstract

A detailed purposive random survey was conducted to understand the farmers behavior on pesticide use and usage pattern in four major beetroot growing districts of Tamil Nadu, India. Beet leaf miner, cut worm, beet leafhopper, green peach aphid and flea beetle were found to infest beetroot crop among which beet leaf miner caused more damage (52.5%). The most commonly used insecticides for leaf miner and other sucking pest management were thiamethoxam 12.6 + lambda cyhalothrin 9.5ZC, profenofos 50EC, quinalphos 25EC, fenvalerate 20EC and cypermethrin 25EC. The source of information for farmers on pesticide recommendations are majorly pesticide retailers (51.25%). A double field experiment conducted in farmer’s field for evaluating the insecticides against leaf miner revealed that cyantraniliprole 10.26 OD @ 60ga.i.ha-1 and thiamethoxam + lambdacyhalothrin 9.5ZC@ 27.5ga.i.ha-1 were effective in reducing leaf miner damage. Knowledge level of farmers on pesticide use and usage pattern and
