Total Sources: 51

Verified Claims: 37

Scientific Sources: 22

Also known as: Omite

Summary

Propargite is a pesticide used to control mites on various crops and ornamentals [15], [23], [24]. It works by inhibiting mitochondrial ATP synthase in mites [23].

What it is

Propargite is a sulfite ester acaricide, meaning it is a type of pesticide specifically designed to kill mites [2], [23]. It is sold in both liquid and wettable powder formulations [15].

Common uses

  • Control of mites on field, fruit, and vegetable crops [15]

  • Use on ornamentals [15]

  • Applications via aerial application, chemigation, airblast sprayer, and high-pressure handwand [15]

Public Perception

Anxiety level

High

Cultural claims

  • Concerns exist regarding the safety of pesticide residues in food and their potential health risks [12].

  • There is a growing interest in natural and organic alternatives to conventional pesticides [12], [31].

Source sentiment

News sources express concern over potential health risks and regulatory decisions regarding propargite and other pesticides [19], [20], [22]. Some advocate for stricter regulations and increased transparency [19], [20], [25]. Anecdotal sources reflect concerns about pesticide exposure and preferences for organic options [39], [40], [41], [42], [43], [44], [45], [46], [47].

History

Timeline

1969

Propargite was first registered as a pesticide in the U.S [15].

1986

EPA issued a Registration Standard for Propargite [15].

1996

An agreement between the EPA and the registrant led to voluntary cancellation of certain uses due to unacceptable dietary risk [15].

1999

Tolerances for 10 uses of propargite were revoked [15].

2005

EPA issued a notice of availability for the modification and closure of the Reregistration Eligibility Decision for propargite [17].

Science

Key findings

  • Propargite has low acute toxicity via oral and dermal routes but is severely irritating to the skin and eyes [15].

  • It is classified as a probable human carcinogen based on the appearance of intestinal tumors in test animals [15].

  • Dietary exposure to propargite is generally low, with exposure from current tolerances representing a small percentage of the acute and chronic population adjusted dose [15].

  • MRLs (Maximum Residue Levels) set by Codex Alimentarius Commission were found to not be adequately supported by data, preventing consumer risk assessment [2].

Studies

Pesticide residues in food: 2023: toxicological evaluations / Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues

This publication is the toxicological monograph from the 2023 Joint Meeting on Pesticide Residues (JMPR) [1].

Review of the existing MRLs for propargite

CXLs (Codex Alimentarius Commission) were found not to be adequately supported by data and a consumer risk assessment could not be carried out [2].

Residential Proximity to Pesticide Application as a Risk Factor for Childhood Central Nervous System Tumors

Residential proximity to pesticide application may be a risk factor for childhood central nervous system tumors [7].

Pesticides may be linked to Parkinson's disease [14].

Evaluation of Propargyl Alcohol Toxicity and Carcinogenicity in F344/N Rats and B6C3F1/N Mice Following Whole-body Inhalation Exposure

Long term inhalation exposure to propargyl alcohol led to nonneoplastic changes in the nose, and increased incidences of respiratory/transitional epithelial adenomas in both mice and rats [48].

Safety status

Propargite is classified as a probable human carcinogen based on animal studies [15]. Long term inhalation exposure to propargyl alcohol, used in the synthesis of propargite, led to increased incidences of respiratory/transitional epithelial adenomas in both mice and rats [48]. It can cause skin and eye irritation and is highly toxic to amphibians, fish, and zooplankton [15], [23].

Nuance

While dietary exposure to propargite is generally low, concerns remain regarding its potential carcinogenicity and other health effects, particularly with long-term exposure [15]. Some studies suggest potential links to cancer and neurological disorders, but more research is needed [7], [8], [14].

Alternatives

Organic Produce

Choosing certified organic produce reduces exposure to synthetic pesticides [33], [37].

Where to find: Grocery stores, farmers' markets [37]

Snap Peas

As a safer alternative to green beans, which may have high-risk pesticide residues [35].

Where to find: Grocery stores, farmers' markets [37]

Sweet Potatoes

As a safer alternative to potatoes, which may have high-risk pesticide residues [35].

Where to find: Grocery stores, farmers' markets [37]

Avoidance tips

  • Wash produce thoroughly under cold running water for 15-20 seconds [37].

  • Scrub firm fruits and vegetables with a soft brush [37].

  • Peel fruits and vegetables to remove residues, but be mindful of losing nutrients in the skin [37].
