Blossom Protect™ and Botector® are highly effective biotechnological plant protection products. They are highly efficient microorganism (Aureobasidium pullulans) in competition with Botrytis cinerea colonizing a microscratch on the plant surface. Botector® contains highly efficient microorganisms which block e.g. the grey mold pathogen, Botrytis cinerea, from colonizing infection sites on the berry surface. The biotechnological product works through natural competition for space and nutrients between pathogens and antagonists. As Botector® acts competitively and does not attack the metabolism of pathogens there is no risk of resistance even with frequent applications.
