Overview
The present invention relates to a broad spectrum biocide comprising mixture of metabolites from different microfungi colonizing the aerial parts of a large number of tropical plants. The biocide effectively inhibits the growth of several fungal and bacterial pathogens as well as reduces disease incidence on a number of crops. The biocide induced defence responses is transmitted to all parts of the plants as well as in later emerging leaves, thereby protecting the crops for a substantial part of their growing season.
