Adjusting Corn Belt Farming to Meet Corn-Borer Conditions

Description: "The European corn borer is recognized as a dangerous enemy of the corn crop.... Its eradication is considered economically impossible but it is believed that the injury may be kept at a point so low that little commercial damage will occur during normal seasons. This can be done by using control measures and practices that have proved to be effective.... On some farms some changes in the crops grown and in their sequence will aid materially in controlling the borer and may prove profitable even when borers are not present. The control program for the individual farm should be given consideration at once in order to avoid sudden disturbance of the organization and operation of the farm when control measures do become inevitable. The necessity of concerted effort by all producers in an infested district becomes evident when the life habits of the borer are considered." -- p. ii

Beekeeping in the Clover Region

Description: "Beekeeping methods suitable for the clover region are well developed but many beekeepers of this region are failing to obtain the full available honey crop because of deficiencies in their practice. A system of management is here given which will result in a full crop from these sources. The variation in the value of the clovers to the beekeeper is also discussed and the methods to be followed in bringing the clover region back to its former prominence in honey production are outlined." -- p. 2
