‘Vates’ col lards were seeded in 4 row plots 20 ft long on Jul 2. Plants were spaced 6-8 inches apart in the row and 36 inches between rows. Each row was buffered by a guard row. The treatments were arranged in a randomized complete block design with 4 replications, the soil was a Norfolk “A” loamy sand. All spray treatments were mixed in 1/2 liter of water and applied with a trombone type garden sprayer calibrated to deliver 30 gal/A. Treatments wee applied on Jul 28; Aug 4, 11, and 18; and Sep 2 and 9. Foliage injury ratings ranged from 1-5 and were indexed as follows: 1) 0-3% damage = odd holes on leaves; 2) 4-10% damage = few leaves with holes; 3) 11-25% damage = moderate number of leaves with holes; 4) 26-50% damage = most leaves with holes; and 5) 51-100% damage = crown damage and/or all leaves with holes.
