What is Propargite?

Description

The pesticide omite pricipally acts as an irritant. Contact dermatitis was reported in 40 of 47 agricultural workers using it.

Chemical properties

Insoluble in water.

The Uses of Propargite

Propargite is a pesticide used to control mite and is used on various crops from cotton to corn.

The Uses of Propargite

Acaricide for fruits, vegetables, row crops.

Definition

ChEBI: Propargite is a sulfite ester and a terminal acetylenic compound. It has a role as a sulfite ester acaricide.

General Description

Propargite is a dark colored liquid. Propargite is a wettable powder or water emulsifiable liquid. Propargite can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Propargite is a liquid Propargite can easily penetrate the soil and contaminate groundwater and nearby streams. Propargite is used as a pesticide. Practically insoluble in water (10.5 mg/L). Used as an acaricide.

Air & Water Reactions

Practically insoluble in water (10.5 mg/L). Slowly reacts with water to form sulfur dioxide and alcohols; reaction is more rapid under basic or acidic conditions.

Reactivity Profile

Propargite is a sulfite ester. As an ester, Propargite will hydrolyze to form sulfur dioxide and alcohols; reaction is more rapid under basic conditions. Propargite may react exothermically with acids to generate alcohols. Heat will be generated by interaction with basic or caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.

Health Hazard

INHALATION: Irritation of mucous membranes. EYES: Irritation, may be severe. SKIN: Irritation.

Flammability and Explosibility

Non flammable

Agricultural Uses

Miticide and acaricide: Pending for use in EU countries. A U.S. EPA restricted Use Pesticide (RUP). Used on a variety of bearing and non-bearing food crops and non-food sites. Grapes, walnuts, almonds, nectarines and mint are the most treated crops. Other crops include alfalfa, avocados, beans, boysenberries, carrots, cherries, citrus, corn, currants, dates, filberts, grapefruit, jojoba, grapes, hops, peanuts, sugar beets, cotton and ornamentals.
