The overall Roundup line of products represented about half of Monsanto's yearly revenue in 2009. [3] The product is marketed to consumers by Scotts Miracle-Gro Company. [4] In the late-2010s other non-glyphosate containing herbicides were also sold under the Roundup brand. [5] [6]
Bioherbicides are herbicides consisting of phytotoxins, pathogens, and other microbes used as biological weed control. [1] Bioherbicides may be compounds and secondary metabolites derived from microbes such as fungi, bacteria or protozoa; or phytotoxic plant residues, extracts or single compounds derived from other plant species.
Surfactants, solvents, and preservatives are inert ingredients, or adjuvants, that are commonly added to glyphosate-based herbicide formulations. [12] Some products contain all the necessary adjuvants, including surfactant; some contain no adjuvant system, while other products contain only a limited amount of adjuvant.
In 2012, Charles Benbrook reported that the Weed Science Society of America listed 22 herbicide-resistant species in the U.S., with over 5.7 × 10 ^ 6 ha (14 × 10 ^ 6 acres) infested by GR weeds and that Dow AgroSciences had carried out a survey and reported a figure of around 40 × 10 ^ 6 ha (100 × 10 ^ 6 acres).

Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
