You should check for pyrrolnitrin and few pyrrolnitrin analogs produced by some strains of Burkholderia cepacia or for additional types of siderophore (such as pyocyanin) and phenazine-type antibiotic produced by Pseudomonas aeruginosa and by P. chlororaphis, respectively.

thank you so much, Sir... I will try to check it.. :)

 Yes ,siderophores  such as pyocyanin and  the antibiotic phenazine produced by a strain of bacterial biocontrol agent Pseudomonas fluorescens can be used against the  pathogen Colletotrichum gloeosporioides in the field . It should be used as prophylacticrather than curative during the initial stages of infection.
