In addition, the multitude of strains of the fungus existing in the united state avoids simple transmission of infections from one stress to another in our woodlands and orchards. An even far better option, would certainly be to have hypovirulence infections enter the spores generated after mating, when numerous brand-new pressure types may be generated by hereditary recombination.
