In vivo inhibitory effect of the BCA candidates against Lasiodiplodia theobromae using the “mango fruit bioassay”. An illustration showing an inoculated-mango fruit with the colonized BCA and/or L. theobromae agar plugs in combinations onto each mango fruit (A). Mango fruit bioassays using BCA1 (isolate #12; Streptomyces samsunensis UAE1) (B); BCA2 (isolate #29; S. cavourensis UAE1) (C); or BCA3 (isolate #44; Micromonospora tulbaghiae UAE1) (D) as potential BCAs. (i) C, a sterile non-inoculated PDA agar plug (control); (ii) BCA, the antagonist alone with a sterile agar plug above it; (iii) Lt, L. theobromae inoculum alone with a sterile agar plug below it; and (iv) BCA+Lt, pairing L. theobromae and the antagonist together, with the BCA on the mango surface and L. theobromae-inoculated plug on top of the BCA.
