Types of Roundup

Roundup is a brand name herbicide used to kill grass, weeds and other vegetative growth. It contains the active ingredient glyphosate. It is sprayed on the foliage of actively growing plants and works its way down to the roots to kill them. Three types of Roundup are available, each available in concentrated forms.

Weed and Grass Killer

Roundup's "Weed and Grass Killer" kills any vegetation that it touches and is available in three concentrates (as of 2010). The ready-to-use bottle is just like it sounds---ready to use. It is already mixed with water and comes with its own sprayer attached to the container. Refills are available for purchase also. The "Concentrate Plus" and "Super Concentrate" must be mixed with water in an herbicide sprayer, according to the manufacturer's directions; they yield up to 10 gallons of spray and 23 gallons of spray respectively.

Extended Control Plus Weed Preventer

The "Roundup Extended Control Weed and Grass Killer Plus Weed Preventer" will kill existing grass and weeds and prevent new growth for four months after application. It is available in a ready-to-use bottle and as a concentrate that, when diluted, provides up to 5 gallons of spray.

Poison Ivy Tough Brush Killer

Roundup's "Poison Ivy Plus Tough Brush Killer" herbicide kills poison ivy, poison oak, kudzu, wild blackberry and other woody brushes. It also comes in a ready-to-use bottle and as a concentrate, which mixes to produce up to 5 gallons of spray. Even after you kill poison ivy or oak, keep in mind that your skin and lungs can still become irritated if breathed in or touched.
