Abstract

Biological control of fungal plant pathogens can improve global food availability, one of the three pillars of food security, by reducing crop losses, particularly for low-income farmers. However, the interrelationships of many environmental variables can result in multiple interactions among the organisms and their environment, several of which might contribute to effective biological control. Here, we present an advanced survey of the nature and practice of biological control when it is used to control brown rot in stone fruit. Specifically, we describe the population dynamics of Penicillium frequentans and Epicoccum nigrum and their efficacy as biocontrol agents against brown rot disease under field conditions. The size of P. frequentans population after an application of a P. frequentans conidial formulation during the crop season is bigger than that of E. nigrum following the application of an E. nigrum conidial formulation. Moreover, applications of a P. frequentans conidial formulation during the crop season also caused a higher reduction in the number of Monilinia spp. conidia on the fruit surface than that found after applications of an E. nigrum formulation during the growing season.
