Management of postharvest disease of mango anthracnose incited by Colletotrichum gleosporioides

Abstract

Among the seven fungal (Gliocladium virens, Trichoderma hamatum, T. harzianum, T. koningii, T. longibrachiatum, T. pseudokoningii and T. viride) and two bacterial (Bacillus subtilis and Pseudomonas fluorescens) antagonists screened against C. gloeosporioides under in vitro conditions, T. harzianum exhibited maximum inhibition followed by Pseudomonas fluorescens at 5 days after incubation. These fungal and bacterial antagonists were selected for application to fruits infected with pathogens. Fruits inoculated with C. gloeosporioides were dipped in spore/cell suspensions of fungal/bacterial antagonists and kept for different durations. The fungal antagonists T. harzianum and P. fluorescens were effective in checking the spread of pathogens on fruits compared with the pathogen-inoculated control.
