Productivity and physiology of kale inoculated with entomopathogenic fungi of Amazon region to control caterpilla

The use of biological control agents such as entomopathogenic fungi is an alternative for the kale(Brassica oleracea L.) defoliating caterpillars. objective was to investigate efficacy entomopathogenicfungi Amazon region in caterpillars kale and their impacts on physiologicaland agronomic responses crop. Field greenhouse experiments were conducted randomized blockdesign completely design, respectively. treatments consisted application isolatesof fungi: Beauveria bassiana, Isaria sp., Metarhizium anisopliae Trichoderma asperellum.The treatment chemical insecticide based deltamethrin.Variablesreferring development, yield physiology plants evaluated. results revealed thatplants treated with B. M. T. asperellum showed levels severity, number ofleaves commercial that did not differ from standard treatment; however, they a lowerpopulation density caterpillar complex. anisopliaeand better photosynthetic performance. In greenhouse, fungus asperellumprovided greater plant height robustness index relation insecticide.The can be contributed integrated management leafdefoliating kale. These microorganisms have similar efficiency insecticides, beingecologically economically viable mitigate negative caused by systematic ofchemicals.
