This field trial was performed on 15-acres of vineyard.
The three treatment blocks had three applications of 30 gallons/acre (mixed 1 oz of Spray-N-Grow/gallon of water). The first application was at bud break, the second shortly after petal fall, and the third 30 days later.
 DOUBLE CURTAIN – 726 Vines Per Acre
Control Block: 24 lbs/vine, 8.71 tons/acre, 19.2 sugar solids
2 Applications: 27.66 lbs/vine, 10.04 tons/acre, 18.9 sugar solids
3 Applications: 47.33 lbs/vine, 17.18 tons/acre, 19.5 sugar solids
The 3 application plot gave a 97% yield increase (8.47 tons per acre). At $180.00/ton, that is an increased income of $1524.60 per acre. Sugar increase = 0.3 Brix.
 STANDARD TRELLIS – 650 Vines Per Acre
Control Block: 31 lbs/vine, 9.37 tons/acre, 17.6 sugar solids
3 Applications: 43 lbs/vine, 13.10 tons/acre, 20.2 sugar solids
The 3 application plot gave a 39% yield increase (3.73 tons/acre). At $180.00/ton, that is an increased income of $671.40/acre. Sugar increase = 2.6 Brix.

We guarantee that your Spray-N-Grow treated crops will produce more than your control plot of the same size and type. Conduct your own trial. Treat both plots the same (fertilizer, water, pesticides, etc.) with the only variable being Spray-N-Grow. Follow all mixing and application directions. At harvest you’ll see the difference! If you are not satisfied, we’ll send a prompt refund.

No questions asked.
