The complete form of TIBA is triiodobenzoic acid. It belongs to the benzoic acid class, with the hydrogens replaced by iodine atoms at positions 2, 3, and 5. The molecular weight of triiodobenzoic acid is 499.81g/mol, and the molecular formula of the same is "begin-aligned."
C_7H_3L_3O_2
\end{aligned}. It is used to control the plant's growth. It is an inhibitor of polar auxin transports. It acts like an antiauxin, suppressing the embryogenic cells and embryo formation. Thus, inhibition of triiodobenzoic acid-induced abnormal embryonic development results in no shoots and roots in plants.

TIBA is an acid used as an agricultural product.
It is used as a regulator to control and accelerate the growth of plants.
TIBA is combined with water to accelerate plant growth.
Mainly Triiodobenzoic acid type of growth regulators are used in oily plants like; Sunflower, which is well adapted to low rainfall and stress conditions of cold, dry lands.
It is much more drought-tolerant than other oil seeds and most cultivated crops.
When the bPIN, SbLAX, and SbPGP gene families were studied in Arabidopsis, rice, and sorghum, it was found that TIBA does not influence abiotic stress on gene expression. So that it is found safe for these plants and can be used like a regulator for plants.
TIBA is dangerous for human and animal use.
In the market, various types of compositions were used as plant regulators; two of them are mentioned below:
Daminozide.
Ethephon.
Oily plants need more water and a long time to grow to produce faster as compared to natural plants, which need hormones for high growth. To increase the growth hormone in the plant, TIBA is used.
For various plants, we can use TIBA as a growth regulator, such as potato, sunflower, soybean, etc.
Triiodobenzoic acid is also used as a growth regulator in woody ornamentals.
During the budding stage, we can use TIBA in a 100 mg/kg solution and foliar spray to increase the yield of potato tubers.
