Rhizoctonia Control with ORO-RZA study was conducted in southeastern Idaho that demonstrated the effect of ORO-RZ on the control of Rhizoctonia in potatoes. Two
widely-used soil-applied fungicides, Quadris (9 oz./a) and Priaxor (6.75 oz./a) were applied in-furrow. In addition, an application of Priaxor
(6.75 oz./a) + ORO-RZ (1 qt./a) was also made in-furrow at planting.
