Indole-3-butyric acid, as an efficient plant rooting agent, is widely used in agricultural seedling raising and has both low toxicity and environmental compatibility. Its potassium salt derivatives further optimize water solubility and safety. When in use, strictly follow the concentration specifications and avoid contact with strong oxidants or high-temperature environments.
Plant growth regulation
Promote root growth: For woody/herbaceous plant cuttings (root soaking concentration: 10-20 mg/L for herbaceous plants, 50 mg/L for woody plants).
Increase survival rate: Soak or mix seeds (100 mg/L for woody plants and 10-20 mg/L for herbaceous plants).
Applicable species: apple, grape, rose, rhododendron, poplar, etc.
Other applications
Pharmaceutical intermediates, pesticide emulsifiers.
It can promote the proliferation of tissue culture seedlings at high concentrations.
Acute toxicity
Oral LD₅₀ in rats: 1000 mg/kg (oral LD₅₀ in white mice is 100 mg/kg).
TLm of carp (48h) : 180 mg/L, non-toxic to bees.
Mutagenicity
Mouse experiments showed no significant chromosomal aberrations or micronucleus effects.
Operation protection
Avoid contact with skin and eyes (protective clothing, gloves and goggles must be worn).
Store in a cool and well-ventilated place (≤30℃), away from fire sources and oxidants.
