"The first widely used herbicide was 2,4-dichlorophenoxyacetic acid, often abbreviated 2,4-D. It was developed by a British team during World War II and first saw widespread production and use in the late 1940s. ..."
No. First herbicides used were probably salts (rock salt, sea salt, potassium salts) more than 2000 years ago (just think about the biblical mentioning of rendering fields sterile by salting the soil, or the same that Romans did around Cartago after its defeat). First technical chemicals, used as herbicides were copper and iron sulfates, sulfuric acid and most importantly, chlorates (sodium, potassium, magnesium chlorates). These were used from the mid 19th century onwards. In early 20th century, petroleum- and tar-derived herbicides, such as creosote oil, the inorganic potassium cyanate (still used in some regions mainly as a defoliant) and first synthetic organic compounds (notably 2,4-dinitrophenol and 2,4-dinitrocresole) went in use. 2,4-D and related compounds were first synthetic selective herbicides.-- 84.163.98.9 17:06, 16 October 2007 (UTC)
This article has been tagged since 2015 with the reason: This article does not discuss the benefits of herbicides and focuses on risks. Herbicides have been universally used in agriculture because of their enormous benefits to society but you wouldn't know that by reading this article
. I am inclined to agree with this since the article still does not discuss any of the benefits of herbicides in terms of increased yield, food security, decreased costs etc. To fix this, we first need to find some suitable sources though.
This is one possibility, but it is US-centric and the authors are pesticide industry advocates, which some may object to. Ideally we'd find a source which is itself more balanced and covers a worldwide viewpoint.

Much of this article is about herbicide resistance. The intended topic of this article is herbicides, not resistance to them. Herbicide resistance is a large topic, so it deserves its own article.-- Smokefoot ( talk) 19:22, 30 December 2023 (UTC)
I have started to rewrite the terminology section here: User:Smartse/hcide. The current version is muddled, omits contact/systemic and large chunks of it are a copyright violation of the Vats source. My intention is to define contact/systemic, pre-em/post-em, selective/unselective and residual and include some examples of each. Just dropping a note here since I noticed Smokefoot has already made some of the same changes I was planning! SmartSE ( talk) 19:50, 2 January 2024 (UTC)
