On August 1, Gary Guge, extension education director; Jeff Bradshaw, graduate student in entomology; and I visited a soybean field north of Little Sioux in Harrison County to view soybean leafminer injury. I must admit that I was skeptical of the amount and magnitude of injury that both Gary and the farmer had described to me over the telephone. When we entered the more than 60-acre field the plants were uniformly small (18-24 inches), mostly from a lack of sufficient moisture, and the entire field had an off-color, light green cast to it from the leaf injury caused by adult soybean leafminers.
