Abstract
The invention belongs to the technical field of biological agriculture, and particularly relates to an aspergillus flavus YJNfs21.11 fungicide and application thereof in prevention and treatment of trialeurodes vaporariorum. The active ingredient of the fungicide is aspergillus flavus YJNfs21.11 spores or spore-free matrix powder obtained by removing the spores after solid fermentation. The invention further provides spore wettable powder and spore-free matrix wettable powder which are prepared from the active components compounded with auxiliaries. Field test results show that the fungicide has efficient and lasting prevention and control effects on adult trialeurodes vaporariorum and eggs, the highest correction prevention effect reaches 99.79%, the technical problem that the prevention effect of an existing biological agent is limited is effectively solved, and a new technical scheme is provided for green prevention and control of trialeurodes vaporariorum.
