Tillage Methods In Grasshopper Control, Gerald B. Spawn
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. The impetus given soil conservation work and farm woodlot and shelterbelt plantings of trees in the past few years has brought about the realization that grasshoppers are far more than …

At the close of 1939 about twice the amount of wheat was in storage in Nebraska as compared to the close of 1938. Frequently a new crop of grain goes into storage before the preceding older grain leaves the farm, and, due to inadequate storage space, the crops are not kept separated, thus promoting an early infestation of the new grain from the older grain that has become infested. Under such conditions the damage by stored grain pests becomes a matter of unusual importance.

Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert
Nebraska Agricultural Experiment Station: Historical Circulars
The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.
