Chlormequat chloride is a white to yellowish
crystalline solid with a fish-like odor.
Plant growth regulator on ornamental plants.
Chlorocholine Chloride is a plant growth regulator that is primarily used on ornamental plants.
A phytocidal bipyridilium quaternary ammonium
salt.
White crystals with a fishlike odor. Used as a plant growth regulator. Said to be effective for cereal grains, tomatoes, and peppers.
Very hygroscopic. Water soluble. Aqueous solutions are acidic.
Chlormequat chloride is incompatible with strong oxidizing agents. Chlormequat chloride is corrosive to unprotected metals.
Inhalation of spray and prolonged or repeated contact with skin should be avoided.
Flash point data for Chlormequat chloride are not available; however, Chlormequat chloride is probably combustible.
Plant growth regulator: Said to be effective for cereal grains, tomatoes, and peppers; cotton, grapes, mango, tobacco, vegetables. In California, major uses are in greenhouse plants and flowers and in nurseries, including geraniums, azaleas, hibiscus.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit. Medical observation isrecommended for 24-48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonaryedema, a doctor or authorized paramedic may consideradministering a corticosteroid spray.
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with chlormequat chloride you should be trained on its proper handlingand storage. Keep away from strong oxidizers. Store in acool, dry place and protect from heat and moisture. Sourcesof ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in amanner that could create a potential fire or explosionhazard.

Chlormequat chloride decomposes on
heating or in fire forming nitrogen oxides, carbon monoxide, and hydrogen chloride fumes. This chemical decomposes on heating with strong aqueous alkali solutions
forming trimethylamine and other gaseous products.
Contact with strong oxidizers may cause fire and explosions. Attacks many metals in presence of water.
Incinerate in a unit with effluent gas scrubbing.
