Frontline Demonstrations: An approach for management of chilli thrips (Scirtothrips dorsalis Hood)
Keywords:
Frontline demonstrations, insecticide, Scirtothrips dorsalis, chilliAbstract
Front line demonstrations were conducted to popularize the recommended practice for the management of chilli
thrips in Panchmahals district of central Gujarat. Results indicated that application of insecticide in recommended practices,
i.e., ethion 40 % + cypermethrin 5 % @ 0.045 % was found most effective in managing chilli thrips (1.07/leaf) as compared
to farmers practices (3.09/leaf). The yield of chilli in recommended practice was 128.13 q/ha as compared to farmer's
practices (80.30 q/ha). The percentage increased in the yield over farmer's practices was computed to be 59.56. Results of
study on economic analysis of the yield performance revealed that the recommended practices recorded appreciable higher
gross returns (10,2500/ha) and net return C 61,725/ha) with higher benefit cost ratio (2.51) as compared to farmer's practices
(1.62). The technology gap (21.87 q/ha), extension gap (47.83 q/ha) and the technology index values (14.58 %) were
recorded. Frontline demonstrations brought out that the recommended practice was feasible and economically viable over
farmers practice and was a better option to adopt for managing chilli thrips.
