Acadian improves cluster architecture and yield of Pinot noir grapes.

• Early season rachis stretch and rachis length measured at veraison was longer in Acadian treated vines by up to 15% over the Control.

• Grapes were visually more uniform in both size and color within bunches and across vines.

• Acadian treatment over all three years resulted in an increase in berries per bunch and in turn, bunch weight itself.

• Yields were notably higher – up to 14% - meaning greater revenue of over $1000 per acre ($1085 per acre, $2679 per hectare)

Acadian at 1.5 quarts per acre

(3.5 liters per hectare) at the

following growth stages:

• 4-6 inch shoot growth: foliar

• One week after last application: soil
