Destructive and non-destructive methods are used to detect diseases in plants. Additionally, understanding the responses of the immune system in plants will further benefit and limit the loss of crops. Typically successful intervention will lead to a low enough level of disease to be acceptable, depending upon the value of the crop. Plant ...
Plant disease forecasting is a management system used to predict the occurrence or change in severity of plant diseases. At the field scale, these systems are used by growers to make economic decisions about disease treatments for control. Often the systems ask the grower a series of questions about the susceptibility of the host crop, and ...
However, disease control is reasonably successful for most crops. Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by plant cultivation approaches such as crop rotation, pathogen-free seed, appropriate planting date and plant density, control of field moisture, and pesticide use.
As with all plant viruses, but especially with those in the genus Tobamovirus, avoidance is the best means of control. Growers must practice good sanitation procedures and only plant clean seeds. Growers must also use caution when handling plants, plants with abrasions or wounds give the virus an opportunity to enter the tissue of the plant.
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 ]
Harmful plant strategies – implementing existing methods and developing new technologies for the identification, exclusion, eradication, and management of invasive weeds and regulated plants. Biological control – developing technologies to allow natural enemies to effectively mitigate the impacts of invasive pests, arthropods, weeds, and ...
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [11] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [12]
In agriculture, disease management is the practice of minimizing disease in crops to increase quantity or quality of harvest yield. Organisms that cause infectious disease in crops include fungi , oomycetes , bacteria , viruses , viroids , virus-like organisms, phytoplasmas , protozoa , nematodes and parasitic plants .
