Comparison of Current Peanut Fungicides Against Athelia rolfsii Through a Laboratory Bioassay of Detached Plant Tissues
(American Phytopathological Society, 2022-08)Southern stem rot of peanut, caused by Athelia rolfsii, is an important fungal disease that impacts peanut production worldwide. Foliar-applied fungicides are used to manage the disease, and several fungicides have been ... -
Rootstock effects on bitter pit incidence in 'Honeycrisp' apples are associated with changes in fruit's cell wall chemical properties
(Frontiers, 2022-10)Bitter pit (BP) is a physiological disorder of apples that often appears during or after cold storage. Despite being defined as a calcium deficiency disorder, BP is a complex process that is not only affected by the total ... -
Fire blight resistance, irrigation and conducive wet weather improve Erwinia amylovora winter survival in cankers
(Frontiers, 2022-10)Erwinia amylovora causes fire blight, a disease responsible for enormous economic losses in the pome fruit-producing areas where it is present. Despite the abundant research on fire blight, information about E. amylovora ... -
Multi-locus genome-wide association studies reveal genomic regions and putative candidate genes associated with leaf spot diseases in African groundnut (Arachis hypogaea L.) germplasm
(Frontiers, 2023-01-05)Early leaf spot (ELS) and late leaf spot (LLS) diseases are the two most destructive groundnut diseases in Ghana resulting in <= 70% yield losses which is controlled largely by chemical method. To develop leaf spot resistant ... -
Condensed Tannins Attributes: Potential Solution to Fescue Toxicosis?
(MDPI, 2023-03-14)Tall fescue (Schedonorus arundinaceous (Schreb.) Dumort. nom. cons. Lolium arundinaceum (Schreb.) Darbysh.) toxicosis results from the consumption of alkaloids released by wild-type endophytes (Epichloe coenophiala) that ... -
Machine Learning Analysis of Hyperspectral Images of Damaged Wheat Kernels
(MDPI, 2023-03-28)Fusarium head blight (FHB) is a disease of small grains caused by the fungus Fusarium graminearum. In this study, we explored the use of hyperspectral imaging (HSI) to evaluate the damage caused by FHB in wheat ... -
Has the Regulatory Compliance Burden Reduced Competitiveness of the U.S. Tilapia Industry?
(MDPI, 2023-03-02)Emerging research on aquaculture governance has pointed to the conundrum of negative global environmental effects from economic incentives for aquaculture production to shift from more highly regulated to less regulated ... -
Impact of Futuristic Climate Variables on Weed Biology and Herbicidal Efficacy: A Review
(MDPI, 2023-02-15)Our changing climate will likely have serious implications on agriculture production through its effects on food and feed crop yield and quality, forage and livestock production, and pest dynamics, including troublesome ... -
A characterization of large-scale swine production and manure generation in Virginia counties and cities located within or outside of the Chesapeake Bay Watershed
(2022)Economies of communities in the Chesapeake Bay watershed depend on commercial and recreational fishing, but various pollutants threaten plants and animals native to the region. Agriculture is the largest source of nutrients ... -
Soybean Yield Response to Sulfur and Nitrogen Additions Across Diverse U.S. Environments
(Wiley, 2022-09)As soybean [Glycine max (L.) Merr.] yields reach record highs, more nutrients are required to maintain these production levels. This study was conducted to evaluate the effect of sulfur (S) and nitrogen (N) on soybean yield ... -
Workload Assessment of Tractor Operations with Ergonomic Transducers and Machine Learning Techniques
(MDPI, 2023-01-27)Dynamic muscular workload assessments of tractor operators are rarely studied or documented, which is critical to improving their performance efficiency and safety. A study was conducted to assess and model dynamic load ... -
