•A plant disease cannot develop if a susceptible host, pathogen, and favorable environment do not occur simultaneously •The major plant pathogens responsible for disease development in plants are fungi, bacteria, viruses, and nematodes •The disease cycle describes the … occurred in 2007, Georgia (USA), it is estimated that approximately 539 USD was the loss incurred due to plant diseases as well as controlling them. In the 1. Myanmar is an agricultural country and then crop production is one of the major sources of earning. Infectious (biotic) » Caused by a living parasitic organism Environmental factors are important in the development of plant diseases and determine whether the diseases become epidemic. Classification of Plant diseases: 1) Endemic diseases: - Endemic means prevalent in and confined to a particular locality. These diseases are more or less constantly present in a particular area. segmentation and classification plant diseases can be divided into four phases: 2.1 Phase 1 - K-means Clustering Technique. to output a predicted disease type or a type of healthy plant species. leaf spot. Two types of diseases. Due to the factors like diseases, pest attacks and sudden change in the weather condition, the productivity of the crop decreases. Plant Disease Classificaiton Before the problem of crop disease detection can be solved, the problem of identifying different species of plants need to be addressed. Find PowerPoint Presentations and Slides using the power of XPowerPoint.com, find free presentations research about Plant Diseases Classification PPT View and Download PowerPoint Presentations on Plant Diseases Classification PPT. What is a disease? Local lesion: A … Due to the factors like diseases, pest attacks and sudden change in the The main categories of microbes that cause plant diseases which are fungi, bacteria, viruses and nematodes. Any abnormal condition that damages a plant and reduces its productivity or usefulness to man. So, more than half of our population depends on agriculture for livelihood. An infection affecting a limited part of a plant e.g. The bacterial spot, late blight, septoria leaf spot and yellow curved leaf diseases affect the crop quality of tomatoes. There is need for developing technique such as automatic plant disease detection and classification using leaf image processing techniques. Systemic infection: infection that spread point of infection to different parts of the plants e.g. Myanmar is an agricultural country and then crop production is one of the major sources of earning. Fortunately, there has been much work already completed in this problem domain. characteristics of plant disease detection machine-learning methods that must be achieved, they are: speed and accuracy [1]. Abstract: The early detection of diseases is important in agriculture for an efficient crop yield. The branch of agriculture or Botanical Science that deals with the cause, etiology, resulting losses and management of plant diseases is called plant … Non-infectious (abiotic) » Not caused by a living parasitic organism; usually an environmental factor 2. 2) Epidemic diseases: - These diseases occur incidentally and occasionally in a particular locality. Automatic methods for classification of plant diseases also help taking action after detecting the symptoms of leaf diseases. This will prove useful technique for farmers and will alert them at the right time wilts, virus infection, loose smut Lesion A localized necrotic or chlorotic areas of diseased tissue/ organ. Fungi account for around 85 percent of plant diseases followed by viruses, bacteria and nematodes. So, more than half of our population depends on agriculture for livelihood. Related Work 2.1. Or, Plant disease is a pathological malfunctioning process of the plant body due to continuous irritation which results in some suffering.
