Is the sale of Chlorpyrifos banned in the US? It is no longer available in California. It was sold under the name Dursban.
I know it's used in mortein cockroach baits. cyclosarin 09:34, 20 December 2006 (UTC)
It is currently used in cockroach baits "HotShot Max-Attrax Roach Bait" - see any product description for details. Clearly not completely banned. — Preceding unsigned comment added by 66.176.44.67 ( talk) 17:41, 17 November 2011 (UTC)
This is still available for sale as an agricultural insecticide. Source: I sell agricultural chemicals for a large ag-chemical retailer. <ref>http://www.cdms.net/LDat/ld73D000.pdf</ref>03:26, 9 August 2012 (UTC)

The synthesis states that "O,O-diethyl phosphorochloridothioate" is used, but an ethyl group has two carbons and the substance shown clearly only has one carbon per group so if anything, the substance is "O,O-dimethyl phosphorochloridothioate" [1] As I cannot vouch for the correctness of the described synthesis, I have, however, not changed the article Saittam ( talk) 07:01, 1 November 2021 (UTC)

Dear Author(s),
I am interested in adding an External Link for this product that directs users to its product information page on the Crop Protection Database (CPD). The CPD is a fact-based, neutral listing of technical information for crop protection products. The CPD listing for this product expands upon the information listed on Wikipedia and would be a valuable addition to the page. This includes experimental code numbers, formulations, action group, outside U.S. registration information, safety guidelines, handling/storage information, emergency guidelines, and a comprehensive list of suppliers, brand names, premix partners, and discontinued products.
Please strongly consider approving my request. For more information, visit: http://www.farmchemicalsinternational.com/cropprotection/cpd/

It is considered a possible endocrine disruptor. (See: "Dursban Warnings", "Dursban Injuries") — Preceding unsigned comment added by Petey Parrot ( talk • contribs) 21:05, 16 June 2011 (UTC)
I can confirm that I recently bought a package of 0.5% Chlorpyrifos in the form of Hot Shot MaxAttrax Roach Bait at a local Walmart here in Oklahoma City, OK. The issue of the ban rumor is addressed directly here:

Chlorpyrifos-methyl redirects to here - however this is a different compound from Chlorpyrifos (sometimes referred to as Chlorpyrifos-ethyl) See [ [1]]. I can't tell if the redirect is mistakenly pointing here because someone thought that it was just another synonym for this compound, or if this is a and attempt to have a single entry for two very similar (and related) pesticides. -- The chemistds ( talk) 09:07, 19 May 2014 (UTC)
The sections on exposure blend human and rat data in a way that is confusing. One suggestion is to separate the animal data and human results. The Wikipedia standards for such reports differ, but we need to be clear that there are two sets of experiments.
Criteria for selecting literature is potentially problematic. Chlorpyrifos has been the subject of 16,197 reports (as of 5 August, 2014). So selection of individual research papers risks being capricious or random (this is what came up when I Googled). For topics where the literature is so massive, one approach is to follow WP:SECONDARY. Since 2004, about 100 reviews have appeared, some of these highly cited and many of these focusing on health issues. Relying on those would possibly enhance the objectivity of the article. -- Smokefoot ( talk) 13:32, 6 August 2014 (UTC) Of the 105 reviews published since 2004, these three are both highly cited, in English, and focus on human-health. They might be relied on to supplant some of the primary references in the article:

I am moving these out of the "external links" section as they're not truly external links, and because there are so many articles about this pesticide I think general papers (rather than reviews, overviews etc) should only be listed if they are cited in the article.
The "Adulthood" subheading under the "Toxicity and Safety" section seems to say two different things in the second line about increased lung cancer risk. The first sentence says that an increase in lung cancer risk was observed in pesticide applicators, but the second sentence says a lower risk rate was observed. Which is it? The second source indicates that a higher rate for pesticide applicators was observed; the first source is now a dead link. — Preceding unsigned comment added by 66.172.112.145 ( talk) 22:46, 29 March 2017 (UTC)
This article is currently unbalanced in its content. For such a widely used insecticide that is approved by regulatory agencies worldwide, there must be a positive benefit-to-risk ratio. Currently, this article really says little about its benefits (small sections on use and application) while the majority of the article is about toxicity, health effects, environmental concerns, etc. A more neutral, balanced approach to discussing this topic is needed. -- Ed ( Edgar181) 13:29, 31 March 2017 (UTC)
I agree. It also has a non-relavant political undertone such as inserting a comment such as: "The Dow Chemical Company, a major producer of chlorpyrifos for use on food for human consumption, contributed $1 million to the Donald J. Trump inaugural committee on December 26, 2016".
It acts on the nervous system of insects by inhibiting acetylcholinesterase. Toxicity results in more than 10,000 deaths a year.
I would have guessed billions and billions, or no-one would buy it.
That clipped second sentence simply can't stand on its own in this context, and it really ought to be more specific regardless.
Someday The Onion is going to run the headline: "Five Deaths from Old Age Now Confirmed from a Single Year / Four Coroners Fined for Lack of Imagination".
Unlike probabilities, death rolls never seem to sum to unity, un unfortunate undercurrent that makes these blunt declarations resemble nothing so much as tabloid click-bait. — MaxEnt 14:41, 10 July 2017 (UTC)
Came here today to find background information on a topic widely appearing in news about 2017 EPA decisions. Disappointed: The article misuses primary sources, drawing firm conclusions in the lede and in the main body based solely on primary sources, in some cases, as few as one (see e.g., see lede reference to an inference taken from the a J. Forensic Leg. Med. article, ref. 6 as of this date, and repeated primary source-arguments in the biological/medical main sections). For instance, in the toxicity mechanisms section, whole paragaphs and subsections stand on single primary source, including, in one case, a source that carries the expression "Preliminary Observations" in its title. This article clearly should be tagged for violation of WP sourcing standards, whatever editors might feel about the regulatory status of the agent in their jurisdictions. Le Prof 98.228.192.239 ( talk) 14:08, 23 October 2017 (UTC)
The section under "Human Exposure" uses a secondary source when the primary source is readily available. "However as of 2016, EPA scientists had not been able to find any level of exposure to the pesticide that was safe." However, this sentence is misleading since it implies that they found that any exposure was unsafe and that is not the case. Due to poor and conflicting data they were unable to reach a conclusion.
Further the partial quote "...this assessment indicates that dietary risks from food alone are of concern..." is not a conclusion of the assessment but is part of an explanation of the methodology. Likewise the quote "chlorpyrifos may not provide a sufficiently health protective human health risk assessment given the potential for neurodevelopmental outcomes." is not a conclusion of the assessment as implied, but is stating the concern that lead to the undertaking of the assessment in the first place.
The article also does not make it clear that the acceptable daily dose includes a 100X safety factor.
