Product Details
2,3,5-Triiodobenzoic acid is a plant growth inhibitor that serves as an important intermediate in the preparation of pharmaceuticals, pesticides, dyes, and other products.
CAS No.: 88-82-4
Molecular Formula: C7H3I3O2
Relative Molecular Mass: 499.81
Toxicity: Low toxicity
Main Formulation: 2% Triiodobenzoic Acid Solution, 98%TC
Physicochemical Properties
The pure product is a white powder or a light brown amorphous powder; it is insoluble in water but soluble in ethanol, acetone, diethyl ether, and similar solvents. Its dimethylamine salt has a melting point of 226–228°C and is soluble in water. It is relatively stable and suitable for long-term storage.
Functional Characteristics
TIBA is a benzoic acid-based plant growth regulator. At low concentrations, it exhibits a weak auxin-like effect, promoting rooting, flowering, and the induction of flower bud formation. At high concentrations, it inhibits the polar transport of auxin within the plant (specifically, the downward transport from the apex), thereby suppressing apical growth, inducing plant dwarfing, and promoting the growth of lateral buds and tillers.
Application Techniques
Soybean
During the period from early flowering to full bloom, a single foliar spray application of a 100–200 mg/L solution can result in sturdier stems, prevent lodging, promote flowering and pod setting, increase yield, and improve quality. However, the efficacy varies among different varieties: the effect is significant in varieties with vigorous vegetative growth; for varieties with moderate vigor and tall stature, a lower concentration should be used; conversely, it is not recommended for varieties with poor vigor or for summer-sown soybeans.
Wheat
During the jointing stage, a foliar spray application of a 100 mg/L solution inhibits the vegetative growth of wheat, resulting in shorter plants and thereby helping to reduce lodging. Simultaneously, it promotes reproductive growth—increasing spike length, the number of grains per spike, and the thousand-grain weight—which contributes to higher yields and also facilitates an increase in protein content.
Peanut
During the early flowering stage, a single whole-plant spray application of a 150 mg/L solution can increase the number of pods per plant, the weight of 100 pods, and the kernel rate, ultimately leading to increased yields. For potatoes, foliar application of a 100 mg/L solution—sprayed 1 to 3 times at 10-day intervals between the bud formation stage and the flowering stage—can promote photosynthesis, enhance nutrient uptake by the roots, and increase tuber yield.
Apples
For the "Fuji," "Ralls," and "Jonathan" apple varieties, a single application of a 300–400 mg/L solution—sprayed over the entire tree or specifically around fruit-bearing branches 30 days prior to harvest—can induce the abscission of rosette leaves on the fruit spurs and leaves at the base of new shoots. Typically, leaves begin to yellow and drop approximately 10 days after spraying, followed by mass abscission at the 14-day and 21-day marks.
Precautions
The efficacy of this product depends on the timing of application and the specific crop variety.
When applying via foliar spray, it is recommended to add a surfactant to ensure stable and consistent results.
