Nf02-518 Management Of Phytophthora Diseases Of Soybeans, Loren J. Giesler, Jane A. Christensen, Christopher M. Zwiener

University of Nebraska-Lincoln Extension: Historical Materials

Phythophthora diseases of soybean, caused by Phytophthora sojae, are present wherever soybeans are grown in Nebraska. The pathogen survives primarily as "resting" spores in the soil or in association with infested crop debris. Symptoms associated with Phytophthora sojae, infections include seed rots, pre- and post-emergence dampin goff of seedlings and stem rot of plants at various growth stages.

Knowledge of the races present in the state and how varieties with different resistance genes have performed in a grower's field is critical to variety selection for maximum profitability.

Nf02-506 Plant Disease Central Web Site, Jim Stack

University of Nebraska-Lincoln Extension: Historical Materials

Disease is a natural part of every crop production system. This is true for all crop species and for each type of production system; irrigated or rain-fed, conventional or conservation tillage, and continuous or rotational cropping. In any given year, the question is which diseases will occur in Nebraska's field crops and at what incidence and severity.

To help producers, consultants, and other agricultural professionals diagnose and manage field crop diseases in Nebraska, the Plant Disease Central (PDC) web site was developed. The home page includes instructions on navigating the site under the "About This Site" link.

Nf02-543 Ascochyta Blight Of Chickpeas, Robert M. Harveson

University of Nebraska-Lincoln Extension: Historical Materials

The chickpea (Cicer arietinum) ranks among the world's three most important pulse (legume) crops. It is an important source of protein in many parts of central Asia, Africa and the Mediterranean and among the food legumes, is the most effective in reducing blood ocholesterol levels. The crop is antive to western Asia and the Middle East, and is usually grown as a rainfed cool-weather crop or as a dry climate crop in semi-arid regions.

Although chickpeas are reported to be susceptible to over 50 pathogens, few diseases are currently recognized as significant economic constraints to production. Ascochyta blight …

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.

Nf02-519 Fungicide Spray Schedule For Home Garden Tree Fruits, Jennifer L. Chaky, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Growing tree fruits in the home garden can be a very enjoyable experience, and with proper management, can provide many years of enjoyment. Success in growing tree frutis depends on following an approach known as integrated pest management, or IPM. In this management program, variety selection, cultural practices and chemical means are used to prevent or reduce losses due to diseases or insects.

This NebFact covers cultural practices, variety selection, the control of disease problems, and how to correctly use chemical controls for a safer environment.
