Note: Field evaluation ofIsaria fumosorosea in controlling the diamondback moth (Plutella xylostella) in Chinese kale

Twelve entomopathogenic fungi were screened for controlling diamondback moth ( Plutella xylostella L.) eggs and larvae in the laboratory. None had any significant ovicidal effect. Isaria fumosorosea CKPF-095 showed the best efficacy in controlling the 2 nd instar larvae. It was formulated into a wet...

Description
Summary:Twelve entomopathogenic fungi were screened for controlling diamondback moth ( Plutella xylostella L.) eggs and larvae in the laboratory. None had any significant ovicidal effect. Isaria fumosorosea CKPF-095 showed the best efficacy in controlling the 2 nd instar larvae. It was formulated into a wettable powder at a concentration of 1 × 10 9 conidia g −1 and used in two field tests. Both tests revealed that I. fumosorosea CKPF-095 at 1.25 × 10 13 ha −1 showed as good efficacy as Dipel at 1 × 10 11 IU ha −1 .
