| Hazard Information | Back Directory | [Hazard]
Moderately toxic by ingestion. Low toxicity by inhalation and skin contact. | [Potential Exposure]
A quarternary ammonium salt herbicide and plant growth regulator registered solely for use on
cotton, to control growth and yield | [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) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Give large
quantities of water and induce vomiting. Do not make an
unconscious person vomit | [Shipping]

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. | [Uses]

| Questions And Answer | Back Directory | [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.
