Vinin®
Most gibberellic acid in Indian vineyards goes into borewell water at pH 7.5-8.5 and hydrolyses before it reaches the berry. Vinin acidifies the tank to pH 3.5-4, where GA₃ is stable, roughly a 50% saving on GA₃, with longer rachis and looser, export-grade bunches.
Vinin is never an extra spray. It goes into every GA₃ tank, at every dip. Approved by NRC for Grapes, Manjari, Pune; developed by Dr. Ashok Raina; in use in Indian vineyards for 25 years.
