PYRETHRINS Chemical Properties,Uses,Production

Description

Pyrethrins/Pyrethrum are natural insecticides produced by certain Chrysanthemum species of plants. In contrast, Permethrin (‘per-meth-rin’) is a synthetic, man-made insecticide, whose chemical structure is based on natural pyrethrum. Pyrethrum was first recognised as having insecticidal properties around 1800 in Asia and was used to kill ticks and various insects such as fleas and mosquitoes. Six individual chemicals have active insecticidal properties in the pyrethrum extract, and these compounds are called pyrethrins. Pyrethrum are viscous, tan-coloured brown resins, liquids, or solids which inactivate readily in air. Pyrethrum are soluble in organic solvents such as alcohol, kerosene, nitromethane, petroleum ether, carbon tetrachloride, and ethylene dichloride. A quick acting liquid insecticide especially suited for control of insect pests of vegetables, ornamentals, and exotic crops. The piperonyl butoxide ingredient is used to enhance the activity of the permethrin (synergist).
Pyrethrum has been used effectively to control insects for decades and is nonpersistent, decomposing rapidly in the environment. This rapid degradation of pyrethrum has resulted in little known cases of insect resistance, making it an excellent choice for the control of agricultural pests, control of insects on pets and/or livestock. Pyrethrum powder is toxic to ants, roaches, silverfish, bed bugs, fleas, wasps, spiders, crickets, mosquitoes, and just about every other category of unwanted house or garden pest. Because it decomposes rapidly in the environment, pyrethrum has been approved for a wide range of indoor and outdoor uses, including homes, restaurants, broad-scale spraying operations, and organic farms.
Pyrethrins break down quickly in the environment, especially when exposed to natural sunlight. Pyrethroids are manufactured chemicals that are very similar in structure to the pyrethrins, but are often more toxic to insects, as well as to mammals, and last longer in the environment than pyrethrins. Pyrethrins and pyrethroids are often combined commercially with other chemicals called synergists, which enhance the insecticidal activity of the pyrethrins and pyrethroids. The synergists prevent some enzymes from breaking down the pyrethrins and pyrethroids, thus increasing their toxicity. Technical-grade (concentrated) pyrethrins and pyrethroids are usually mixed with carriers or solvents to produce a commercial-grade formulated product.

Chemical Properties

Viscous liquid. Oxidizes readily in air. Insoluble in water; soluble in other common sol- vents. Incompatible with alkalies.

Chemical Properties

Pyrethrum is a variable mixture of compounds which are found in cinerin, jasmolin, and pyrethrin. Pyrethrum is a brown, viscous oil or solid.

Uses

Household insecticide (flies, mosquitoes, gar- den insects, etc.).

Definition

Pyrethrolone ester of chrysanthemummonocarboxylic acid. Most potent insecticidal ingredient of pyrethrum flowers.

Air & Water Reactions

Oxidize relatively rapidly in air. Water emulsifiable.

Reactivity Profile

PYRETHRINS decompose rapidly in base; may generate heat with caustic solutions. May also react with acids to liberate heat. Generate flammable hydrogen with alkali metals and hydrides.

Hazard

Toxic by ingestion and inhalation.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Potential Exposure

Pyrethrins are used as an ingredient of various contact insecticides. Those engaged in the isolation, formulation, or application of these materials.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ- ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi- cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN2902 Pesticides, liquid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo- sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Compounds of the car- boxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic com- pounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sul- fate and oxides of sulfur).
