How growers make decisions impacts plant disease control
Whilst the spread of plant disease depends strongly on biological factors controlling transmission, epidemics clearly also have a human dimension. Disease control depends on decisions made by individual growers, who are in turn influenced by a broad range of factors. Despite this, human behaviour …

Role of Subcellular Differentiation in Plant Disease Resistance
… in the isoprenoid pathway. In solanaceous plants, one class of endproducts of the pathway are sesquiterpenoid phytoalexins, antibiotic compounds produced by plants in response to pathogens. We are interested in the role of the defense-inducible isoforms of HMGR in phytoalexin production and …

An investigation into the role of deubiquitinating enzymes in plant disease resistance
… increasingly apparent during the last decade. In plants, regulated degradation by the ubiquitin/26S proteasome has been implicated in diverse signalling events including embryogenesis, hormone signalling and disease resistance. Ubiquitin moieties are ligated to target proteins through the …

Protecting valuable resources using optimal control theory and feedback strategies for plant disease management
Mathematical models of tree diseases often have little to say about how to manage established epidemics. Models often show that it is too late for successful disease eradication, but few study what management could still be beneficial. This study focusses on finding effective control strategies for …

Characterization of arbuscular mycorrhial fungi on Glycine max and its influence on plant disease severity
… associations with over 80% of all terrestrial plant species and assist plants by increasing nutrient uptake, drought tolerance, and resilience against pathogens and pests. However, the level of benefit may be variable and be host-genotype dependent. Genotype variation to AMF colonization and …

A Unified Framework for Distributed and Resource-Aware Plant Disease Detection Using Federated and Adaptive Hybrid Deep Learning
<p>Plant disease detection in precision agriculture must operate under significant computational constraints, particularly in low-resource (LR) environments such as unmanned aerial vehicles (UAVs) and edge devices. While LR models enable efficient real-time inference, they often lack the …

A detail laboratory and library study of fruit diseases
… the writer with some of the more important fruit diseases. Material where available was brought into the laboratory and microscopic studies made of the host symptoms and causal organisms. Hesler and Whetzel's “Manual of Fruit Diseases," “The Plant Disease Reporter,” and “The Experiment Station …

Detection of the Oak Wilt Pathogen in Sapwood of Northern Oak Species Using PCR Technology
… by Ceratocystis fagacearum, is important when disease control action is planned. When laboratory diagnosis is needed, standard isolation protocols that are used rely on high quality samples and require up to 14 days for incubation. New methods, involving the use of polymerase chain reaction …

Studies on the Gecko P521 Cone-Type Pigment
… were used to identify components of the plant disease resistance pathway. The availability of the dnd mutants may facilitate further study of the control of HR cell death, gene-for-gene resistance, and broad spectrum disease resistance in plants.

Advancing Explainability in Multi-Label Classification for Tomato Disease Detection Using Machine Learning Interpretability Techniques
<p>Plant diseases pose a significant threat to global food security, affecting crop yield, quality, and overall agricultural productivity. Traditionally, diagnosing plant diseases has relied on timeconsuming visual inspections by experts, which can often lead to errors. With the rapid growth of …

Purification, Characterization, Elisa Optimization and Dosage Effects of Beet Western Yellows Virus
Best Western Yellows (BWY) was described as a plant disease of viral etiology in 1960. The adjective 'western' was selected to distinguish BWY from beet yellows (BY), a previously described yellowing disease of sugarbeet. BWY virus (BWYV) is believed to be of greater economic importance than BY …

Cross -Commodity Price Linkages: A Cointegration Analysis of Food Markets in Java
… increase in the price of rice, (i.e. a rice plant disease), can lead to an increase in demand for corn and cassava and hence rises in their prices. It also induces a market intervention from the governments. In conclusion, the results from this cointegration analysis implies that government …

Segmentation of the market for labeled ornamental plants by environmental preferences: A latent class analysis
… for a labeling program applied in ornamental plant sales, given key ongoing issues affecting ornamental plant producers: irrigation water use and plant disease. Our research investigated how to better understand the market for plants certified as disease free and/or produced using water …

The treatment of bacterial disease of plants by bacteriophage coated nanoparticles
… are a recurring issue for agricultural plants.Traditional control measures include copper treatment and use of pesticides and antibiotics. The use of bacteriophages that selectively kill the causative pathogen as an alternative treatment has been delayed by technical difficulties …

Studies on the Epidemiology of Stem Rust in South Dakota
… warranted unlimited study and discussion of this plant disease among scientific and practical grain growers. Most of the study has been on the life cycle of stem rust in order to suggest control measures. Some workers express considerable importance on the heterocism of the fungus, thus favoring …

Dissection of General and Specific Disease Resistance Pathways in Arabidopsis Thaliana
… object of this study was to genetically dissect plant disease resistance using Arabidopsis thaliana and the bacterial pathogen Pseudomonas syringae. Genetic and molecular approaches were used to identify components involved in this pathway. A screen was conducted to look for Arabidopsis mutants …
