Acute oral LD50 for 1000-5900 mg/kg, on the skin and mucous membranes have a stimulating effect.a-Naphthylacetic Acid is Broad-spectrum plant growth regulator. Absorbed via root, stem and leaf. It can promote cell division and expansion, induce formation of adventitious root and improve fruit set, change male/female ratio of flowers.


1. NAA is a broad-spectrum-based plant growth regulator, it can promote cell division and expansion.
2. NAA is suitble for cereal crops, increase tillering, improve the percentage of panicle rate and grain weight.
3. Reduce cotton ball falling, increase fruits weight, and improve the quality.
4. Promote fruit trees flowering, prevent the fruit falling off, and promote early-maturing and increase production.
5. Prevent fruits and vegetables from falling flowers, change female and male flowers ratio.
6. Promote cutting branches rooting.
