Seedling damping-off by Phomopsis/Diaporthe

In the past 2 years, soybean top dieback, also called tip blight by growers, has emerged as a disease concern to some growers. The disease was initially reported in Ohio 20 years ago and was first noticed in Iowa in 1997. Foliar symptoms of this disease occur during the reproductive stage of soybean plants in August, but the fungi associated with the disease can cause damage during the seedling stage. In the 1998 growing season, we received reports and questions from producers on the occurrence of black lesions on cotyledons. In this article we provide information on seedling disease caused by the same fungi that caused these lesions

Soybean top dieback shows up

In the 1997 and 1998 growing seasons, some soybean fields had plants with bright yellow leaves and plants that were dying from the top down, a condition called top dieback (growers may call this condition tip blight). Top dieback was pronounced in 1997 and 1998 from late July to mid-August when most soybean plants were in the reproductive phase. Top dieback showed up again this year

Herbicide-tolerant crops and plant diseases

Crop management is a dynamic activity that changes as technologies are developed. During winter extension activities, there were some discussions on soybean diseases observed on Roundup-Ready soybeans. This article takes a proactive approach to address some concerns that were commonly raised about herbicide-tolerant crops, herbicides, and the occurrence of plant diseases.</p

Status, Trends, and Management of Soybean Studies Death Syndrome and White Mold

In the past five to six years disease picture has changed significantly in Iowa soybean production. The 1998 growing season was characterized by the occurrence of several soybean diseases. Two of these diseases, sudden death syndrome and white mold, are discussed in this article, with respect to their current status, trends, and management options.</p

Characteristics of Organically Grown Compared to Conventionally Grown Potato and the Processed Products: A Review

Interest in organic foods is increasing at a moment when humanity is facing a range of health challenges including the concern that some conventionally produced foods may pose possible adverse effects on human and livestock health. With the increasing human population, intensive production is increasingly trending towards high-input systems that aim to close yield gaps, increase crop yields, and develop new crop varieties with higher yield potential and tolerance to biotic and abiotic stresses, all within the context of incorporating specific traits to satisfy consumer demand. Potato (Solanum tuberosum L.) is one of the most consumed foods under different cultural diets; however, its production faces some challenges related to soilborne diseases, marketable yield and quality, sugars and dry matter content of the produced tubers, tuber content in terms of nitrate, minerals, vitamins, bioactive compounds, and antioxidants, and consumer appreciation regarding the sensory characteristics of tubers and processed products. Different studies have been investigating some of these challenges, with sometimes straightforward and sometimes conflicting results. This variability in research results indicates the general non-transferability of the results from one location to another under the same management practices in addition to differences in plant material. This review compares some characteristics of raw or boiled potato and processed products from potato tubers grown organically and conventionally. Ideally, such information may be of benefit in decision making by consumers in their dietary choices, by potato growers in their selection of crop management practices, and by scientists looking at potential areas for future research on potatoes
