Concentrate spray trials in 1962 using low volume application rates substantiated the previous year's encouraging results with this new pest and disease control technique. In field trials for control of several major pests in deciduous fruit and nut crops, concentrate spraying with chemicals applied at 60 gallons per acre offered control equal to that obtained with conventional “dilute” spray rigs applying the same chemical concentration in a total of 400 gollons of spray per acre.
