Abstract

Germination tests of thousands of samples of the seed corn on Iowa farms indicate that a large percentage of it is unfit to plant, due to the various corn ear molds which were so common last fall, and principally to the dry rot of corn. It Is Important that seed corn be carefully examined and selected this spring, and ·then tested. Some of the diseased ears can be detected by examination alone, but not all. It is essential also to use the germination test to be wholly sure of good seed. Moldy corn was common In fields thruout the state last fall. In the central and eastern counties, from 2 to 15 percent of the ears were left in the field because of the mold, while many partially diseased ears found their way Into the seed corn. The corn grower has already taken his loss incurred in the corn harvest, but the loss due to poor seed is still to follow.
