Nf02-504 Atrazine And Non-Atrazine Herbicide Comparisons In No-Till Corn, Fred Roeth, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

Atrazine herbicide has been in an EPA special review since 1994 because of soil surface runoff concerns. Beginning in 1997, we evaluated atrazine and non-atrazine herbicide treatments in conventional tillage corn and no-till corn on university research farms at Clay Center (irrigated) and Lincoln, Nebraska (non-irrigated). The objective was to compare some common atrazine and non-atrazine herbicides in soil-applied and post emergence treatment combinations. Fourteen herbicide treatments were selected to represent commonly used herbicide classes and application timings. This NebFact reports the no-till results.

Nf02-520 Fungicide Spray Schedule For Home Garden Small Fruits, John E. Watkins, Jernnifer L. Chaky

University of Nebraska-Lincoln Extension: Historical Materials

Home grown strawberries, raspberries and grapes are a rewarding experience for the gardener as well as the consumer of the fresh fruits and jellies. If properly managed, these crops can be a source of enjoyment for years. To be successful, however, the home gardener must develop a sound integrated pest management (IPM) approach to controlling diseases and insect pests. A good IPM program makes use of cultural, varietal and chemical means of preventing or reducing disease losses.

This NebFact discusses which fungicides to use for which disease of small garden fruits and provides recommendations for a fungicide treatment schedule.

G98-1777 Windbreak Renovation, James R. Brandle, Jon Wilson, Craig Stange, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks are an integral part of many farms and ranches and provide critical protection for farmsteads, livestock and crops. Unfortunately, many windbreaks planted in the 1930s and 1940s are losing their effectiveness due to age, poor health or neglect. In some cases, the windbreak no longer has the necessary density to provide winter protection. In other cases, overcrowding may have reduced the health and vigor of the windbreak, or the windbreak may have been invaded by aggressive sod-forming grasses such as smooth brome, reducing tree growth. Whatever the reason, many older windbreaks need renovation.

Nf97-328 A Guide To Grasshopper Control In Cropland (Revised May 2004), Gary L. Hein, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Grasshoppers have been a major concern to farmers and ranchers since Nebraska was first settled. The potential for devastation, while still serious, is not as great as it was 100 years ago because many of the prime grasshopper breeding areas along the eastern slopes of the Rocky Mountains are now under tillage. Statewide, grasshopper populations fluctuate in cycles with large numbers occurring for two to four years, followed by moderate numbers for several years.

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska’s adverse weather conditions affect winter wheat during much of its growth. The newer varieties of wheat have increased winter hardiness, and better management practices have reduced winter injury of winter wheat, yet low temperature injury during winter and spring can be destructive. Wheat has little resistance to low temperatures after it begins growing in the spring; therefore, injury from freezes at this time can occur in any part of the state. This publication describes temperature conditions that cause winter injury, symptoms of injury at different spring growth stages, and management practices to use when wheat is injured.

G94-1196 Vegetables And Herbs As Ornamentals (Revised November 1996), Susan D. Schoneweis
