Abstract

In brinjal ecosystem, jassid cause enormous damage to brinjal. Hence, investigation on Harnessing natural arsenal for effective management of jassid on brinjal was carried out during 2022-23 and 2023-24 at S. D. Agriculture University, Sardarkrushinagar, Gujarat, India. The most effective treatment was Azadirachtin 1500 ppm (0.0006%), reducing jassid population to 1.44 jassids/leaf, followed by Lecanicillium lecanii 1.15 WP (1×108 cfu/g) at 0.0046 per cent, which recorded 1.82 jassids/leaf. Other treatments, such as NSKE at 5 per cent (2.14 jassids/leaf) and NSKE + Cow urine (2.36 jassids/leaf), also showed good results. Dashparni ark (2.55 jassids/leaf) and Neemastra (2.85 jassids/leaf) were moderately effective, while Brahmastra and Panchparni ark were less effective, both recording 3.20 jassids/leaf. The study highlights the potential of Azadirachtin and Lecanicillium lecanii as sustainable, effective treatments for jassid management in brinjal.
