what is Paclobutrazol 95 TC ?
Paclobutrazol 95 TC is an inhibitory triazole plant growth regulator, which is an inhibitor of endogenous gibberellin synthesis. It can significantly weaken the apical growth advantage, promote the growth of lateral buds (tillers), thicken the stem, and make the plant dwarf and compact. It can increase the content of chlorophyll, protein, and Ribonucleic acid, reduce the content of Gibberellic acid in plants, and also reduce the content of Indole-3-acetic acid and increase the release of Ethylene. It mainly works through root absorption. The amount absorbed by the leaves is small enough to cause morphological changes, but it can increase yield. The control effect of paclobutrazol on crop growth has high application value. Herbs and woody flowers treated with paclobutrazol have a compact plant shape and greater ornamental value. Paclobutrazol has a longer shelf life in soil. Pay attention to plowing the medicinal plot after harvest to reduce the inhibitory effect on the following crops

what are the use of Paclobutrazol 95 TC?
It is a new, efficient, and low toxicity plant growth regulator with broad-spectrum bactericidal effects
It has the function of hindering plant growth and shortening the pitch. If used in rice, it can increase the activity of indole-3-acetic acid oxidase in rice, reduce the level of endogenous IAA in rice seedlings, significantly control the growth rate at the top of rice seedlings, promote leaf division, make the leaves dark green, develop the root system, reduce lodging, and increase panicle yield. The general growth control rate is 30%, and the leaf promotion rate is 50% to 100%. The yield increase rate reached 35%.
Used for peach, pear, citrus, apple and other fruit trees, it can "control the shoots and keep them trapped", making the tree shape shorter.
Chrysanthemums, geraniums, poinsettia, and some ornamental shrubs treated with paclobutrazol have their plant shapes adjusted to enhance their ornamental value.
Cultivating greenhouse vegetables such as tomatoes and rapeseed has a significant effect on strengthening seedlings.If you need it, pls click e-mail sales1@faithfulbio.com
what is the Mechanism of action of Paclobutrazol 95 TC?
Paclobutrazol 95 TC can be absorbed by plants through roots, stems, and leaves. The multi effect azole absorbed by the roots is transported upwards through the xylem towards the top of the plant. After absorption, the leaves move slowly, and paclobutrazol inhibits the growth of plants or branches. This effect is mainly achieved by inhibiting the synthesis of Gibberellic acid. In the process of inhibiting the synthesis of Gibberellic acid, it mainly inhibits the intermediate three processes from Avalon sodium salt → kaurene → kaempferol → KAURENAL → kaurene acid → Gibberellic acid, without inhibiting the synthesis of kaurene or affecting the subsequent processes of kaempferol. By inhibiting the synthesis of gibberellin, cell division and elongation are reduced. It not only greatly reduces the amount of GA synthesized in plants, but also reduces the content of IAA and increases the content of endogenous ethylene ABA and cytokinin. Paclobutrazol can effectively regulate and control plant growth and development at the hormone level by altering the hormone balance in plants.

How long is the degradation metabolic period of paclobutrazol 95 TC?
Paclobutrazol 95 TC enters the body from the roots and has minimal effect when sprayed onto the plant. It mainly enters the soil surface and is absorbed by the roots, and travels through the conduit rather than the sieve tube. Distributed within the body, leaves account for the highest 50.3%, followed by roots at 44.3%, and rarely remain in the stem. The half-life of paclobutrazol in plants varies depending on the conditions, generally ranging from 3 to 12 months. The degradation rate of paclobutrazol in plants varies depending on the different parts of the plant.
According to the experiment, after 9 days of treatment, 71.5% of peach trees remained in the roots, 41.5% to 68.1% in the stems, and only 7.8% to 12.2% in the leaves. The main component remaining in apples is PP333 (approximately 50%), with the vast majority located in the skin. The half-life in soil is 3 months. Paclobutrazol can be quickly excreted from the body of mammals. In sheep, about 90% of the dose is excreted, with only a small amount present in milk and other tissues. The main components of the remaining substances are PP333 and diols. In hens, approximately 88% of the dose is eliminated from the body within 14 days of feeding. Glycols (mainly in bound form) are the main residual components in egg yolks and liver.
