Cultivated plants are constantly exposed to pathogens, and the subsequent development of symptomatic disease causes vast economic losses throughout the agricultural industry. A great need exists for the development and use of improved antimicrobial products to control plant pathogens.
Our goal is simple: to replace toxic fungicides and antibiotics with eco-friendly alternatives that help build an environmentally sustainable world. Nature provides environmentally-friendly antimicrobials that are safe yet very effective.
PhylloTech’s core technology is based on our discovery that some plants secrete defensive proteins termed phylloplanins. This novel family of secreted plant proteins inhibit a broad range of agricultural pathogens. Our scientists have published reports on phylloplanin effectiveness and the results of their endeavors are clear: phylloplanins are extremely effective, broad-spectrum pathogen controls. We believe these antimicrobial proteins are the next generation of environmentally-friendly biofungicides and genetic crop traits to enhance disease resistance.
Quorum sensing is a biochemical process that allows bacterial populations to coordinate gene expression and plays a significant role in the onset of pathogenesis and biofilm development. PhylloTech is currently developing environmentally-friendly methods to interrupt this process and limit the impact of bacterial pathogens on crop diseases.
