Plant diseases can also be partially controlled by use of pesticides and by cultivation practices such as crop rotation, tillage, planting density, disease-free seeds and cleaning of equipment, but plant varieties with inherent (genetically determined) disease resistance are generally preferred.

27 records of plants. Origin Africa. This species' phanerogam has the highest cobalt content. Its distribution could be governed by cobalt rather than copper. [36] [1]: 891 [33] Cu: Helianthus annuus: Sunflower: Phytoextraction with rhizofiltration [1]: 898 [33] Cu: 1000: Larrea tridentata: Creosote Bush: 67 records of plants. Origin U.S. [1 ...
Plant viruses are a cause of around half of the plant diseases emerging worldwide, and an estimated 10–15% of losses in crop yields. [162] Papaya, potatoes, and squash have been engineered to resist viral pathogens such as cucumber mosaic virus which, despite its name, infects a wide variety of plants.
Plant viruses are generally transmitted by a vector, but mechanical and seed transmission also occur. Vectors are often insects such as aphids ; others are fungi , nematodes , and protozoa . In many cases, the insect and virus are specific for virus transmission such as the beet leafhopper that transmits the curly top virus causing disease in ...
Biopesticides usually have no known function in photosynthesis, growth or other basic aspects of plant physiology. Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use.

To date, work on induction of plant systemic resistance has shown that inducing plant system resistance work has important implications for basic and applied research. Induced resistance applications in melons, tobacco, bean, potato, and rice have achieved significant success. Over the past decade, the study of induced system resistance has ...
Sickle Cell genetic resistance to Malaria [1] Disease resistance is the ability to prevent or reduce the presence of diseases in otherwise susceptible hosts. It can arise from genetic or environmental factors, such as incomplete penetrance. [2] Disease tolerance is different as it is the ability of a host to limit the impact of disease on host ...
