Application
Indolylacetic acid (IAA) is a kind of indole broad-spectrum plant growth regulator with
somatotropin activity.
1.IAA affects cell division and cell elongation;
2.IAA is used to stimulate rooting of herbaceous and woody ornamentals and increase the
size of fruit;
3.IAA prevents blossom fall and fruit drop before fructification and fruit ripening, flower
& fruit thinning flower introduction, increase output.Toxicology
Acute percutaneous toxicity for mouse LD50 1000mg/KG;
Acute intraperitoneal toxicity LD50 150mg/Kg.
LC50 for carp (48hr),40ppm.
Non-toxic for bees at normal dosage.Package
1kg/bag, 25kg/drum
