Plant disease epidemiology is the study of disease in plant populations. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants. [1] Plant disease epidemiologists strive for an understanding of the cause and ...
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [ 1] Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance ...
Plant disease. Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [ 1] Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus -like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. [ 2]
Pyramids. v. t. e. The scale-invariant feature transform ( SIFT) is a computer vision algorithm to detect, describe, and match local features in images, invented by David Lowe in 1999. [ 1] Applications include object recognition, robotic mapping and navigation, image stitching, 3D modeling, gesture recognition, video tracking, individual ...
Relative to a susceptible plant, disease resistance is the reduction of pathogen growth on or in the plant (and hence a reduction of disease), while the term disease tolerance describes plants that exhibit little disease damage despite substantial pathogen levels. Disease outcome is determined by the three-way interaction of the pathogen, the ...
Pseudomonas syringae. P. s. pv. persicae (Prunier, Luisetti &. Gardan) Young, Dye & Wilkie[ 1] Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella. As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [ 2] all of which are available to researchers from international ...
Pyramids. v. t. e. The histogram of oriented gradients (HOG) is a feature descriptor used in computer vision and image processing for the purpose of object detection. The technique counts occurrences of gradient orientation in localized portions of an image. This method is similar to that of edge orientation histograms, scale-invariant feature ...
Plantix[ 1][ 2] is a mobile crop advisory app for farmers, extension workers and gardeners. Plantix was developed by PEAT [ 3] GmbH, a Berlin-based AI startup. The app claims to diagnose pest damages, plant diseases and nutrient deficiencies affecting crops and offers corresponding treatment measures. Users can participate in the online ...
