On Friday, April 20, 2018, three rows each of eight chemical suckering treatments (below) were applied to the bottom half of grapevines to produce visual results for a demo where growers could draw their own conclusions. The Lodi Winegrape Commission is not promoting one product over another nor providing a recommendation – this demo is for educational purposes only. A special thanks to Joe Valente for organizing the trial and hosting this pop up vineyard demo!
