Plant Health Care plc announces research cooperation to determine Harpin protein mode of action against nematodes.
Plant Health Care is pleased to announce it has entered into a research partnership with one of the leading scientists in the field of Nematology from the University of Arkansas. The partnership has been established to determine the biochemical reactions in Plant Health Care's Harpin protein, that causes its documented effectiveness against a wide variety of nematodes and, in particular, the Soybean Cyst species that has proven to be resistant to most conventional chemicals. Nematodes cause billions of dollars of damage to crops around the world annually and Harpin has been a proven deterrent to this pest. Harpin proteins are signal molecules that alert plants to the presence of pathogens, particularly bacteria. Their attachment to receptors on the plants' surfaces initiates a cascade of genetic responses that promote plant health, encourage disease resistance, and defend against nematodes.
Trials at the University of Arkansas, Cornell University, Auburn University, Mississippi State University, Illinois State University, Michigan State, Texas A&M, and others have shown up to 60% reductions of nematode eggs on plant roots when the seed or the early-developing plant itself has been activated by Harpin protein technology. Unlike conventional chemical nematicides, Harpins affect parasitic plant nematodes without affecting beneficial soil nematodes, which are the bulk of nematode species found in healthy soil.
