Different agricultural practices, such as the use of crop rotation, cover crops, disease resistant varieties, and good seed bed preparation have been applied to control pests and diseases. However, such practices are not always sufficient protection from crop losses. Because of this, many certified organic growers turn to bio-pesticides to insure and/or enhance their abilities to grow and market high-quality produce. Such products have been developed to control numerous plant diseases and to provide useful tools for growers to decrease the incidence and/or severity of plant diseases.
