There are two types of electron microscope, the Scanning Electron Microscope [SEM] and the Transmission Electron Microscope [TEM]. Scanning Electron Microscope shows the external and whole image of a specimen such as a dust mite, or a nit. The Transmission Electron Microscope is literally the opposite.
Combat Extremeâ¢ Southern Zone - is a 3-way mixture of turf type fescue and Hybrid Bluegrass which is heat and drought tolerant enough to be used in USDA Zones 8 - 10 (partial shade recommend for USDA Zone 9 and 10). This mixture is approximately 90% turf type fescue grass seed and 10% hybrid bluegrass seed by weight. By seed count, this makes almost a 50/50 blend of fescue and hybrid drought tolerant bluegrass.
Tall fescues. Tall fescue is a perennial bunch-type grass that grows rapidly during spring and fall. Because of its bunch-type growth, spring pre emergence herbicides generally are needed to keep a lawn relatively free of weeds.Not recommended to mix with bluegrass as the bunching characteristics will create unsightly patches.escue grasses. The fescue is a bunch type grass, as opposed to the rhizomatic growth of bluegrass. Newer cultivars have the same rich green color as bluegrass.
