Tillage Methods In Grasshopper Control, Gerald B. Spawn Nov 1940

Tillage Methods In Grasshopper Control, Gerald B. Spawn

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

During the past 88 years of agricultural history in South Dakota, 38 have been years in which grasshoppers were present in above normal numbers. During 17 of these 38 years grasshoppers have been a serious pest of agricultural crops in South Dakota and neighboring states. Many millions of dollars worth of cereal, forage and truck crops during each of these 17 years were destroyed by hungry hordes of the insects.
