Halosulfuron-methyl is a sulfonylurea post-emergence herbicide used to control some annual and perennial broad-leaved weeds and sedges (such as nutsedge/nutgrass) in a range of crops (particularly rice), established landscape woody ornamentals and turfgrass. [citation needed] It is marketed under several tradenames including Sedgehammer [2] and ...
Pendimethalin protects crops like wheat, corn, soybeans, potatoes, cabbage, peas, carrots, and asparagus. It is used to control annual grasses and certain broadleaf weeds which interfere with growth, development, yield and quality of agricultural and horticultural crops by competing on nutrients, water and light.
The differences in broadleaf weeds' structure and growth habits make them easy to distinguish from narrow-leaved weedy grasses. [5] Most broadleaf weeds have leaves with net-like veins and nodes that contain one or more leaves, and they may have showy flowers, [6] while grassy weeds appear as a single leaf from a germinated seed.

Dithiopyr is a preemergent herbicide for crabgrass control in turf and ornamental grasses. It is effective on 45 grassy and broadleaf weeds. [1] Dithiopyr inhibits root growth of susceptible weeds as well as turf grass and thus should be used only on established turf with a well-developed root system.
Mecoprop (also known as methylchlorophenoxypropionic acid and MCPP) is a common general use herbicide found in many household weed killers and "weed-and-feed" type lawn fertilizers. [3] It is primarily used to control broadleaf weeds . [ 4 ]
Imazaquin inhibits the acetohydroxy acid synthase (AHAS) enzyme accountable for synthesis of the amino acids valine, leucine, and isoleucine. When applied, imazaquin halts weed growth which eventually kills the weed or causes the weed to die due to its incapability to compete with surrounding vegetation.
The Cyperaceae (/ ˌ s aɪ p ə ˈ r eɪ s i. iː,-ˌ aɪ /) are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large; botanists have described some 5,500 known species in about 90 genera [3] [4] – the largest being the "true sedges" (genus Carex), [5] [6] with over 2,000 species.
Other names are blueweed, Lady Campbell weed, Riverina bluebell, and purple viper's bugloss. Three other Echium species have been introduced and are of concern; viper's bugloss (Echium vulgare) is the most common of them. Viper's bugloss is biennial, with a single unbranched flowering stem and smaller, more blue flowers, but is otherwise similar.
