In vitro activity of purpureocillium lilacinum isolates against phytopathogenic fungi of sorghum

Abstract

Metabolites produced by antagonist on the growthof phytopathogens fungus. The three P. lilacinumisolates had variable inhibitory activity accordingto the type of assay and phytopathogen evaluated.However, the inhibition was more evident with P.lilacinum Ls isolate and mainly with the effectof the non-volatile compounds. This studysuggests that P. lilacinum could be considered apromising antagonist in the control of Alternaria.These results motivate us to go deeper in theproduction, isolation and identification of thecompounds produced by this specie. The studiedP. lilacinum Ls isolate could be another tool in thedifferent biological control strategies applied tothe conservation of sorghum grains.
