Evaluation of bio pesticidal formulations of plant origin against Cyllodes indicus (Coleoptera: Nitidulidae) in Pleurotus sajor caju (In vivo)
Author(s): Neeta Devi Sharma and Anju S Khanna
Abstract: Three biopesticidal formulations of plant origin viz., Max Raze, Max Cannon and Neemazal when tried against C. indicus showed high efficacy for first fortnight after application as evident from statistically similar mushroom production during this period in the bags receiving insects and formulations and insect free bags in Pleurotus sajor caju. However, due to the speculated low persistence of these formulations, the insect population started building up after about twenty days of application, thus reducing the yields in third and fourth week of cropping. However, significantly improved average yields were recorded in biopesticides receiving treatments as compared to the bags in which only adults of C. indicus were released. Among the tested formulations, Max Raze yielded best results followed by Max Cannon. The least effective was Neemazal, though, yield improvement by this formulation was also significant. Visually, no infestation of sporocarps was observed during first and second week, but with the reducing efficiency of biopesticides, more and more sporocarps got infested. Highest sporocarp infestation among the treated bags was observed in Neemazal treated bags.
