Hazard InformationBack Directory
[Hazard]

Skin irritant.
[Potential Exposure]

A carboxylic acid plant growth regulator used for thinning fruit sets in apples, pears, olives, and some citrus. Induces root formation on cuttings and transplants. Inhibits fruit drops. Not currently registered in EU countries (may be pending).
[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. Do not induce vomiting when formulations containing petroleum solvents are ingested.

UN1759 Corrosive solids, n.o.s., Hazard Class: 8; Labels: 8-Corrosive material, Technical Name Required.
[Incompatibilities]

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, chlorates nitrates, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Compounds of the carboxyl 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 compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).
[Waste Disposal]

Incineration. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
Questions And AnswerBack Directory
[Description]

1-naphthaleneacetic acid (NAA, also named as α-naphthaleneacetic acid) belongs to a class of organic compounds of naphthalenes, which contain a naphthalene moiety of two fused benzene rings. NAA is a synthetic auxin plant hormone. It is used as a plant growth regulator to control preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives, and citrus fruits. It is used as a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture and as herbicide. Applied as a dust or spray it delays dissolution of the abscission layer, retarding the fruit drop. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. When used after four weeks, NAA stimulates shoot growth, while full-time use limits growth. When used in a 4-week pulse, adventitious root growth is greatly increased.
