Efficiency of Nimbecidine and certain entomopathogenic fungi formulations against bean aphids,Aphis craccivorain broad bean field

This study investigates the effect of certain entomopathogenic fungi formulations (Beauveria bassiana, Verticillium lecanii, Metarhizium anisopliae and Paecilomyces fumosoroseus) compared with a botanical insecticide, Nimbecidine against Aphis craccivora in broad bean field. Bio-Catch (Verticillium lecanii) was the most effective insecticide to achieve 73.3% reduction followed by Nimbecidine (67.7%), Bio-Magic (61.6%), Priority (50.3%) and the least effective was Bio- Power (Beauveria bassiana) which caused 45.5% reduction in individual aphid populations after two sprayings at 15 days interval between the first and the second sprayings. Bio-Catch and Nimbecidine had promise compounds in controlling Aphis craccivora in faba bean fields.
