La bermuda es una planta perenne de estación cálida ampliamente utilizada para su uso como césped en el sudeste de los Estados Unidos.
[Although improved common (Cynodon dactylon (L.) Pers.) and hybrid bermudagrasses (Cynodon dactylon x C. transvaalensis Burtt-Davy) have desirable qualities as turfgrasses for heat, drought and wear tolerance, bermudagrass is a problematic weed when grown in mixed stands with other turf species. Selective control of bermudagrass is difficult but often warranted in order to maintain acceptable quality of the desired turfgrass species. This publication describes bermudagrass control methods for Southern lawns.]

Aflatoxin is a naturally occurring toxin produced by the fungus Aspergillus flavus. The fungus can be recognized by a gray-green or yellow-green mold growing on corn kernels in the field or in storage. Plant stress due to drought, heat or insect damage during fungus growth usually increases aflatoxin levels. Aflatoxin contamination will reduce feeding value and hinder sales. Because it is extremely poisonous to warm-blooded animals even at relatively low levels, grain handling facilities often check for the presence of the toxin before purchasing corn.

La lespedeza común (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) es una leguminosa anual de verano sin organización en sus ramificaciones, que es una maleza problemática en céspedes de jardines residenciales así como en otras áreas de césped.
[Common lespedeza (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) is a freely branched, summer annual legume that is a problematic weed in lawns and other turf areas. This publication describes ways to identify and control Lespedeza in turfgrass, including cultural control methods, preemergence herbicides and postemergence herbicides.]

Annual bluegrass (Poa annua L.) is a problematic winter annual weed in residential turf. Compared to most turfgrasses, annual bluegrass has a lighter green color, coarser leaf texture and produces unsightly seedheads. Contrary to its name, both annual (live for one season) and perennial (live for many seasons) biotypes of annual bluegrass may be found in turf. This publication describes methods of control for annual bluegrass in residential turfgrass lawns.

Total Maximum Daily Loads in Georgia
A total maximum daily load (TMDL) is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards. This publication contains comprehensive information about total maximum daily loads in Georgia, including their importance and how to establish an implementation plan.

Georgia’s Water Quality Standards
The Environmental Protection Division (GAEPD) of the Georgia Department of Natural Resources (GADNR) is responsible for setting and enforcing water quality standards. The goals of establishing these standards are to “provide enhancement of water quality and prevention of pollution; to protect the public health or welfare in accordance with the public interest for drinking water supplies, conservation of fish, wildlife, and other beneficial aquatic life, and agricultural, industrial, recreational, and other reasonable and necessary uses and to maintain and improve the biological integrity of the waters of the State.” This publication contains comprehensive information about Georgia’s water quality standards and what the public should know about bodies of water that do not meet these standards.

Watershed Assessment in Georgia
Watershed assessment is the measurement and use of chemical, physical and biological properties to determine the current health of streams. It also can include the use of predictive modeling of watershed conditions and suggests management practices that will maintain and improve the health of a watershed. This publication provides information on the components of a watershed assessment and how to implement these plans.
