Date: 1991
Location: Almathea Vineyards – Atco, New Jersey

Acres: 1 acre
Applications: First – when shoots 1″ long, second – post bloom
Rate: 1 ounce Spray-N-Grow / gallon, 50 gallons per acre
Equipment: Hydraulic sprayer
Harvest date: 9/7, hand picked

Spray-N-Grow Treated
Yield: +600lbs/acre (3,500 lbs/acre)
Sugar: +1.5 (21.5)
Acids & Ph: no significant difference

Yield: 2,900 lbs/acre
Sugar: 20.0
Acids & Ph: no significant differences
COMMENTS: Treated plants generally more vigorous and had better overall color. Fruit set heavier with fuller bunches on treated plants. Earlier ripening. Fruit hung on better and longer which extended the hand picking season. Differences in yield would probably be greater in a poor growing year relative to temperature and rainfall.

Interested in the influences of Spray-N-Grow on leaf retention in the fall and possible carbohydrate increase to help resist winter damage to vinifera types. Applied a late application in July toward this end. Will continue trials next year.

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.
