In Arizona weeds are nearly impossible to be rid of, and a lot of them actually can pierce through your shoes into your feet....this is the desert of course. A lot of us have to user services. Weed control Tucson is worse still I think, and there's a company called Essential Pest Control that we use for pretty much anything related to weeds and pests in general.
Anyone fancy doing a copy-edit on this article for duplicated links, formating mistakes etc? I'm getting a bit word-blind with it now... Thanks quercus robur 13:32 16 Jun 2003 (UTC)
eh, you did quite a good job !
I think some stuff need to be reorganised though. I see not why agriculture was dissociated from the above paragraphs which applied to farming just as they apply to gardening. I will try later to add some stuff about resistance management, and the different recommandations defined manage resistance happening. Recommandations are about herbicides choice, but involve using other techniques as well. ant
"In June, weeds are in their"... but June is winter in some regions. Ya bitch.
"can produce 1000 seed,": add "s". Or not.
"sometimes livestocks,"... no "s"? I question this because it may not be right.
Homemade weedkiller advice
Strictly speaking, and ludicrous though it may seem, it is illegal in the UK (and possibly throughout the EU?) to advise anyone to use, or to use yourself, any home-made pesticide (this includes weedkillers), however innocuous and everyday the ingredients might be (eg putting salt on slugs). It's also illegal to use any commercial pesticide/weedkiller product for a purpose for which it is not specifically licensed, or at a dosage not recommended on the pack or accompanying literature. See The Food and Environment Protection Act (1985) (FEPA), the Control of Pesticides Regulations (1986) (COPR) and the Plant Protection Products Regulations (1995) (see pdf file entitled PESTICIDES - Legislation) SiGarb | Talk 22:29, 21 February 2006 (UTC)
- Weed should have a section on weed control. It's known as summary style. Richard001 (talk) 00:03, 12 May 2010 (UTC)
Propose merge of "legislation" section with "noxious weed"
The term "noxious weed" is used in the New World, but not the UK or Europe, but a similar concept exists there. WP is a catalouge of concepts not of terms (for that see wiktionary). Therefore I propose a merger.--Kevlar (talk • contribs) 16:09, 31 December 2013 (UTC)

Is there a specific reason why the methods haven't been grouped into mechanical/physical, cultural, biological and chemical control? If there are no objections, I plan on restructuring the section. Elspamo4 (talk) 23:25, 9 December 2015 (UTC)
Herbicides The above described methods of weed control use no or very limited chemical inputs. They are preferred by organic gardeners or organic farmers.
However weed control can also be achieved by the use of herbicides. Selective herbicides kill certain targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often based on plant hormones. Herbicides are generally classified as follows:
Contact herbicides destroy only plant tissue that contacts the herbicide. Generally, these are the fastest-acting herbicides. They are ineffective on perennial plants that can re-grow from roots or tubers. Systemic herbicides are foliar-applied and move through the plant where they destroy a greater amount of tissue. Glyphosate is currently the most used systemic herbicide.. Gel formulations of systemic herbicides work by being introduced directly into individual weed plants and trees' vascular system. This targeting avoids the off target damage of sprays. Although mainly applied to cut-stems these gels herbicides can also be applied to leaves. Gels are available in New Zealand and used widely in forest restoration, conservation and environmental projects. A variety of active ingredients are used including glyphosate, picloram and metsulfuron. Soil-borne herbicides are applied to the soil and are taken up by the roots of the target plant. Pre-emergent herbicides are applied to the soil and prevent germination or early growth of weed seeds. In agriculture large scale and systematic procedures are usually required, often by machines, such as large liquid herbicide 'floater' sprayers, or aerial application. — Preceding unsigned comment added by 220.127.116.11 (talk) 22:09, 18 January 2017 (UTC)
