Stromatinia cepivora is a fungus in the division Ascomycota.It is the teleomorph of Sclerotium cepivorum, the cause of white rot in onions, garlic, and leeks. [2] The infective sclerotia remain viable in the soil for many years and are stimulated to germinate by the presence of a susceptible crop.
Garlic will keep longer if the tops remain attached. [19] Garlic is often kept in oil to produce flavored oil; however, the practice requires measures to be taken to prevent the garlic from spoiling which may include rancidity and growth of Clostridium botulinum. [66] Acidification with a mild solution of vinegar minimizes bacterial growth. [66]
Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
Phytoncides are a biologically active substance of plant origin that kills or inhibits growth and development of bacteria, microscopic fungi, and protozoa. Phytoncides play an important role in plant immunity and in the relationships between organisms within an ecosystem. [2] The ability to produce phytoncides is a quality common among plants.
Bacteria live in soil water, including the film of moisture surrounding soil particles, and some are able to swim by means of flagella. The majority of the beneficial soil-dwelling bacteria need oxygen (and are thus termed aerobic bacteria), whilst those that do not require air are referred to as anaerobic , and tend to cause putrefaction of ...
D. dipsaci is a microscopic worm about 1.5 mm long. It penetrates plants from either the soil or infested planting material and occasionally from seeds. They live between the cells of onion or garlic leaves and between the scales of the bulbs where they feed on cell sap and multiply.
Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
Releasing clay and silt particles reduces the capacity for soil to absorb water and increases cross surface flow, accelerating soil erosion. In addition soil litter reduces wind erosion by preventing soil from losing moisture and providing cover preventing soil transportation. Organic matter accumulation also helps protect soils from wildfire ...
