Yissum and Dow ink ethylene deal

Israeli technology transfer company Yissum Research Development (Jerusalem) agreed a deal earlier this year with Dow Chemical subsidiary AgroFresh to develop a new plant growth regulator. The agreement anticipates the possible marketing of Yissum’s water-soluble ethylene-based product. Existing gaseous or wettable powder solutions have very limited use in open spaces, such as fields or greenhouses, Yissum says. Unlike gaseous ethylene antagonists, such as 1-methylcyclopropene (1-MCP), the new product can be sprayed in the field, plantation, or greenhouse, or applied to cut flowers, and is effective as a pre- and post-harvest treatment. AgroFresh president José Pina says the deal allows the companies to validate the potential of the compound and “if warranted”, market it. The product has been developed between the Israeli Bi-national Agricultural Research Development Fund and the US North Carolina State University, and tested on wheat, and has shown efficacy on cotton, tobacco, tomatoes and cut flowers.
