Low-cutting devices for harvesting corn
1929
Irons, Frank | Parvis, W. J. (Willard Jay)
Removal of all cornstalks from the field for later shredding, ensiling, or burning is one of the most effective means of controlling the European corn borer. For satisfactory control by this method, it is necessary that the stalks be cut off at ground level, thereby leaving no stubble. By this means most of the borers can be removed from the field in the stalks.
