Description

Grasshoppers have done considerable damage to South Dakota field crops during the past few years. Last year, reports from various parts of the state show severe injury to alfalfa, corn, small grains, gardens, and other crops. The injury usually centers around alfalfa fields, but the grasshoppers attack and destroy almost any green crop available. It have been demonstrated in South Dakota that control measures can be adopted that will serve to keep these insects in check. Natural factors are, of course, important in the control of any insect, and their many enemies greatly reduce the numbers of grasshoppers each year. However, our experience has proven that we cannot rely on these natural enemies to protect us from injury, it being necessary to add our own efforts to those of nature if we are to prevent loss.
