Gliocladium virens (GL-21) was evaluated as a granular in-furrow fungicide. Trials were conducted at eight mid-south locations. Two planting dates, early and late, were established at each location. Terraclor^® 10G was applied at the rate of 10 lb/A. GL-21 was applied at two rates (3 and 5lb/A), either alone or in combination with Terraclor granules at 5lb/A.

GL-21 alone did not provide consistent improvements in stand counts. The addition of Terraclor 10G (5 lb/A) to GL-21 (3lb/A) resulted in stand counts that were comparable to Terraclor alone. There was an indication that GL-21 was more effective under high moisture conditions. Treatments made at the early planting date tended to improve stand counts more than those made at later planting dates.
