Abstract
Many microorganism are with good antagonistic potential, however fail to be developed for practical use, due to inconsistent performance associated with field applications and often adverse environmental conditions. The EU emphasizes the necessity to know crop safety and evaluate the production of secondary metabolites on fruit surface together with their risk on human. Mycotoxins from Penicillium species can be a serious contaminant problem in storage fruit. Pf 909 is used as a BCA against brown rot in stone fruit caused by Monilinia spp. Penicillium frequentans (Pf909) efficacy is very dependent on its survival and persistence on flower and fruit surfaces, which depend on the climate. This study tries to achieve part of the registration requirements necessary for authorization of BCA Pf909 in EC countries. Identifying areas of research that still need to be addressed to demonstrate that Pf909 is sufficiently stable on field conditions and crop safe for registration purposes. This work is divided into three major sections: effect of physical factors on Pf909 development; the antagonist spectrum of resistance to commercial products use for conventional animal and human fungi control; and descharge mycotoxic production by Pf909 on fruit surface. Pf909 survive actively over a wide range of environmental conditions. The probability of risks to human and animal health is considered to be remote in terms of mycotoxic production, and there is commercial active material capable to inhibit fungus growth
