This work aimed to broaden the spectrum biocontrol activity of Meyerozyma guilliermondii LMA-Cp01. Inhibition of postharvest pathogens, viz., Alternaria alternata, Penicillium italicum, P. digitatum, P. expansum, Botrytis cinerea, and Rhizopus stolonifer was tested on persimmon, oranges, apples, and pears. The effect of spraying or dipping application of the actinomycete for the phytopathogens biocontrol was evaluated. LMA-Cp01 reduced 30 and 50% (R. stolonifer), 53 and 67% (B. cinerea), and 55 and 67% (P. expansum) the disease incidence and severity on apples, respectively. Regarding pears, reductions of 44 and 71% (R. stolonifer) and 65 and 85% (P. expansum) of incidence and severity were respectively achieved. P. italicum and P. digitatum incidence on oranges was reduced by 70 and 72%, respectively, and the severity was also reduced by 85%. The LMA-Cp01 efficacy on apples and oranges was higher by spraying application. LMA-Cp01 is a promising broad-spectrum biocontrol agent against diseases on different hosts. [ABSTRACT FROM AUTHOR] |
