Antagonistic effect of BCA candidates against mango dieback disease under greenhouse conditions. Effect of preventive biocontrol treatment of (A) Streptomyces samsunensis UAE1 (BCA1; isolate #12); (B) S. cavourensis UAE1 (BCA2; isolate #29); and (C) Micromonospora tulbaghiae UAE1 (BCA3; isolate #44). The number of (D) defoliated leaves; and (E) conidia after recovery of the pathogen from affected mango stem tissues (cv. Badami) at 6 and 9 wpi with L. theobromae, respectively. In (D,E) values with different letters are significantly different from each other at P < 0.05. C, non-inoculated control seedlings, Lt, seedlings inoculated with L. theobromae only; Ss, Sc or Mt, seedlings inoculated with only S. samsunensis UAE1, S. cavourensis UAE1 or M. tulbaghiae UAE1, respectively; Ss+Lt, Sc+Lt or Mt+Lt, seedlings inoculated with the individual BCA, S. samsunensis UAE1, S. cavourensis UAE1 or M. tulbaghiae UAE1, respectively, 1 week prior to L. theobromae inoculation; wpi, weeks post inoculation.
