G95-1250 Rust Of Dry Bean, James R. Steadman, H. F. Schwartz, Dale T. Lindgren Jan 1995

G95-1250 Rust Of Dry Bean, James R. Steadman, H. F. Schwartz, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

The symptoms, sources, spread and management of rust in dry edible beans is discussed in this NebGuide.

Rust is an important disease that affects dry beans in eastern Colorado, western Nebraska and adjacent regions. The disease is caused by the fungus Uromyces appendiculatus which has caused periodic epidemics in this region since the 1950s. Recent yield losses from the disease have exceeded 50 percent in some areas.

G95-1272 Blue Mustard Control, Gail A. Wicks, Drew J. Lyon, Robert N. Klein

University of Nebraska-Lincoln Extension: Historical Materials

Blue mustard is a serious weed in winter wheat and alfalfa in central and western Nebraska. This NebGuide discusses methods of control.

Blue mustard [Chorispora tenella (Pallas) D.C.] was introduced into the U.S. from Siberia in 1929 and was first reported in Lewiston, Idaho. It was identified in Keith County Nebraska in 1953.


Nf95-218 Conjunctive Use Policy Options, William Miller Jan 1995

Nf95-218 Conjunctive Use Policy Options, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

Background

The hydrologic cycle controls water available for use. Rainfall, evaporation, runoff, percolation, and transpiration combine to influence the water available at a specific location at a particular point in time. The speed at which water moves among stages in the hydrologic cycle and the amount of time it spends in storage at any stage affects water availability to users. The conjunctive use issue refers to the portion of the hydrologic cycle where groundwater and surface water interface and influence each other.

Users who couldn't depend on an irregular flow of water over time developed systems that modify the variable …


G95-1241 Annual Broadleaf Weed Control In Winter Wheat (Revised January 1999), Gail` A. Wicks, Robert N. Klein, Alex Martin, Drew J. Lyon Jan 1995

G95-1241 Annual Broadleaf Weed Control In Winter Wheat (Revised January 1999), Gail` A. Wicks, Robert N. Klein, Alex Martin, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This guide discusses preventive, cultural, and chemical weed control in winter wheat. The best weed control is obtained by using a combination of these methods. Winter and summer annual broadleaf weeds have an important economic impact on Nebraska winter wheat. They compete with winter wheat for water, light, space, and nutrients, reducing Nebraska winter wheat yields by an estimated 10 percent each year. The dollar loss, with wheat at $2.50 per bushel, is over $2.1 million per year. Weeds also slow harvest and increase combine repair costs. Producers may be docked at the elevator for excessive grain moisture and/or weed …


G95-1264 Storing Fresh Fruits And Vegetables, Susan D. Schoneweis, Durward Smith Jan 1995

G95-1264 Storing Fresh Fruits And Vegetables, Susan D. Schoneweis, Durward Smith

University of Nebraska-Lincoln Extension: Historical Materials

The following NebGuide outlines proper storage methods and conditions for fresh fruits and vegetables.

Harvesting fruits and vegetables from your garden at the proper stage of maturity is only the first step to fresh table quality. Proper harvesting and post-harvest handling methods, as well as proper storage of fruits and vegetables not immediately eaten, will help maintain the flavor, texture and nutritive value of the produce.

Proper storage means controlling both the temperature and relative humidity of the storage area. All fruits and vegetables do not have the same requirements. This NebGuide will help you select the best storage conditions …


Ec95-1560 Use Of Cultural Practices In Crop Insect Pest Management, Robert J. Wright Jan 1995

Ec95-1560 Use Of Cultural Practices In Crop Insect Pest Management, Robert J. Wright

University of Nebraska-Lincoln Extension: Historical Materials

This Extension Circular reviews what is known about the effects of rotations, tillage practices, and planting and harvest dates on crop insect management, focusing on major crops in Nebraska.

Before the development of synthetic organic insecticides (pre-DDT era), rotations, tillage practices, planting and harvest dates, and other nonchemical cultural controls were commonly recommended for insect management. Research focused on crop rotation and other cultural practices for insect management. With the development of DDT and later insecticides however, research on nonchemical controls decreased markedly.

With the emergence of the concept of sustainable agriculture in the 1980s, there has been increased emphasis …


G95-1270 Sclerotinia Stem Rot Of Soybeans, James R. Steadman, S. Rutledge, D. Merrell, David Wysong Jan 1995

G95-1270 Sclerotinia Stem Rot Of Soybeans, James R. Steadman, S. Rutledge, D. Merrell, David Wysong

University of Nebraska-Lincoln Extension: Historical Materials

Life cycle, symptoms, and control measures of sclerotinia stem rot of soybeans is discussed.

Sclerotinia stem rot of soybeans is caused by the fungus Sclerotinia sclerotiorum. This pathogen has an extremely wide host range and can affect more than 400 plant species, including oilseed, vegetable and forage legume crops. S. sclerotiorum has caused a disease known as white mold on dry edible beans in western Nebraska for 40 years, but it did not become a problem in soybeans until the 1990s. This fungal pathogen can be found on soybeans in Illinois, Iowa, Michigan, Ohio, Minnesota, Wisconsin, and North Dakota. …
