Meloidogyne Acronea
''Meloidogyne acronea'', the African cotton root-knot nematode or African cotton root nematode, is a plant pathogenic nematode affecting pigeonpeas. It is also an invasive species An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species ad .... The roots and surrounding soils of cereals, grasses, and Gossypium spp. provide habitat for this organism. M. acronea was confirmed as a potentially problematic pest of cotton, Gossypium hirsutum cv.

Coetzee
Coetzee () is an Afrikaans surname. It is the tenth most common family name in the Republic of South Africa. Origin Unlike many other popular South-African family names, which can often be unambiguously traced back to English, Dutch, or Huguenot French, the origin of the name Coetzee is unclear. It is known that it dates back to the person Dirk Coetzee who came to Cape Colony from Kampen in Netherlands in the 17th century. Dutch linguist Jan-Wouter Zwart states the guess, in an informal essay, that it derived from the common Dutch name Koetsier, guided by the pronunciation. Notable people with the surname "Coetzee" * Allister Coetzee (born 1963), South African rugby coach * Angeline Coetzee, doctor who individuated Covid-19 Omicron variant * Basil Coetzee (1944–1998), South African musician * Clem Coetzee ( – 2006), Zimbabwean conservationist * Danie Coetzee (born 1977), South African rugby union footballer * Dirk Coetzee (1945–2013), co-founder and commander of the cov ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Pulse Crop Diseases
In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck ( carotid artery), wrist (radial artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior tibial artery), and on foot (dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers. This has a reason: the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart (usually the ring finger) is used to nullify the ...
