ABSTRACT
Insecticidal evaluation of aqueous extracts of indigenous plant extracts in
comparison with synthetic insecticide against Thrips (Scirotothrips dorsalis) on tomato was
conducted under natural field condition during spring 2019. Experiment consisted of 8
treatments (neem extract, tobacco extract, garlic extract, datura extract, lantana extract,
eucalyptus extract, flonicamid (synthetic insecticide) and control followed RCB Design with 3
replications. Treatments were applied thrice after 15 days interval. Results revealed that
the three times application of the tested treatments showed varying toxicity against S.
dorsalis 24, 48, 72 hours and 7 days after spray applications while ladybird beetle and
green lacewing were also significantly affected when recorded 7 days after spray
application. However, Flonicamid 50%WG proved to be the most effective till 7th and had
lowest pest population followed datura and neem extract. neem extract in all the three
spray application . Garlic and eucalyptus also produced significant results compared to
control. Neem, tobacco, datura and flonicamid were found comparatively more hazardous to
ladybird beetle and green lacewing population compared to eucalyptus, garlic and lantana to
in all three spray application. Tomato yield was highest with flonicamid (12533 kg/ha)
followed by datura and neem (11810 kg/ha and 11300 kg/ha) respectively, while lowest
(8133 kg/ha) in control. It is concluded from the current research that flonicamid performed
better against S. dorsalis but comparatively more hazardous to natural enemies however
lantana, garlic and eucalyptus extract showed better result against S. dorsalis and
comparatively safe towards natural enemies thus recommended to be incorporated in IPM
program.
