Description

Mepiquat chloride (N, N-dimethylpiperidinium chloride), well known as PIX, is a potential systemic plant growth regulator. It is applied in cereals including wheat, oats, barley, rye, triticale and is extensively used in the cotton production. It is intended to increase yield by inhibiting gibberellic acid synthesis. The use of mepiquat chloride results in a shorter and more compact plant, lower leaf area index due to smaller leaf size and earlier maturity.

Uses

Plant growth regulator.

Definition

ChEBI: A quaternary ammonium salt consisting of equimolar amounts of mepiquat cations and chloride anions. A plant growth regulator, it is used in agriculture to reduce vegetative growth including sprout suppression in garlic, leeks and onions.

Hazard

Moderately toxic by ingestion. Low toxicity by inhalation and skin contact.

Incompatibilities

Decomposes in temperatures above 320��. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Noncombustible containers should be compacted and buried under more than 16 in/40 cm. of soil. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
