ProTone Plant Growth Regulator Makes Short List For Chicago Innovation Awards

Valent BioSciences Corporation’s ProTone, a plant growth regulator that enhances the color of table grapes, is a finalist in the Chicago Innovation Awards program. The program is designed to recognize innovative new products and bring attention to the locally developed product and service innovations that are making a global impact. ProTone also is a candidate for the People’s Choice Award, with online voting continuing through October 14 at the program website: Awards will be presented Nov. 1.


ProTone is a low-risk, environmentally friendly product that enhances the red coloration of red grapes by stimulating the natural pathway in plants that leads to anthocyanin (color) biosynthesis. ProTone also is the first commercial product based on Valent BioSciences Corporation’s newest active ingredient, abscisic acid (S-ABA), which naturally occurs in plants. S-ABA regulates numerous processes in plants, including responses to stress conditions, dormancy, maturation, abscission, and growth.
