Barley

"Barley production in Missouri usually increases following a drought. Livestock producers need feed if corn supplies are low or need pasture if grass is not recovered."--First page.James A.

Corn cutworm control

"This guide recommends management practices and insecticides for reduction of injury caused by the various cutworms attacking corn in Missouri. It also discusses the life cycles of the more common species which feed at and below ground and those species which are primarily above ground foliage feeders."--First page.Gene Munson, Armon J. Keaster, and Judy A. Grundler (Department of Entomology, College of Agriculture)Revised 2/86/4.5

Control of wireworms and other corn soil insects 1984

"This guide recommends management practices and insecticides for reduction of the following corn soil insect pest problems: wireworms, white grubs and annual grubs, billbugs, sod webworms, seed damaging insects, bird and rodent damage to seed and seedlings and insect pest control in no-tillage sod plantings."--First page.Gene Munson, Armon J. Keaster, and Judy A. Grundler (Department of Entomology College of Agriculture)Revised 2/84/5

Corn rootworm control 1984

"The three species of corn rootworms attacking corn in Missouri are commonly known as northern, southern and western corn rootworms. The northern and southern species are state-wide in their distribution. The western species is known to occur over the northern two-thirds of the state Gasper to Perry Counties and northward). Western corn rootworm larval and adult numbers were on on the increase in 1983 and comprised over 90 percent of the total rootworm population in the research plots in northwest Missouri. The potential for economic damage from northern and western species is also confined to the northwestern counties, extending from Buchanan County northeastward to Harrison County."--First page.Gene Munson, Armon J.

Soil insect control in reduced tillage cropping systems

"Missouri row crop producers have rapidly accepted and adopted reduced, conservation or no-till practices. They planted 45 percent or 5,000,000 acres of the 1983 crop of soybeans, corn, small grains and grain sorghum in soil receiving some degree of reduced tillage. Although reduced tillage practices offer several advantages, one disadvantage is difficult insect control. Major insect problems occur more frequently and are often more damaging with reduced than with conventionally tilled crops."--First page.Gene Munson, Armon J. Keaster and Judy A. Grundler (Department of Entomology, College of Agriculture)Revised 2/84/6

The Varied Character of the Des Moines River Valley in Central Iowa

The drainage system on the Des Moines River is quite varied between Humboldt and Des Moines. The variation in drainage characters is highlighted on a map prepared from aerial photographs and topographic sheets. The northern part of this area is associated with the Mankato drift sheet and is characterized by poorly developed, non-integrated drainage. The central part of the drainage system in Boone County flows across the Cary ground moraine. In this area the tributaries are short, intermittent, and deep, and appear as gullies and washes. Just south of Des Moines, the drainage makes another sharp change, and in this area is associated with the Kansan drift. It is well integrated and featured by a relatively small number of far-reaching primary tributaries. It seems to be more than coincidental that the change in character of the drainage is so closely associated with the relative ages of the drift sheets comprising the drift plain

Grain storage management : guide for keeping your grain in top condition (1989)

"New 1/89/2M."Storage fungi can cause serious losses in stored grain. They are the cause, not the result, of spoilage. Bin burning, mustiness and heating are often associated with storage molds. In wheat, germ damage or "sick" wheat can occur. Storage fungi invade the genns primarily and preferentially, so both commercial grain and grain held for seed are vulnerable to storage molds.Introduction -- Common storage problems -- Storage molds and their control -- Storage insects and their control -- Aerating and checking grain during storage -- Managing grain in flat stroarage systems -- Observation and actions in management of dry stored grai
