Application features:
Paclobutrazol is a triazole plant growth regulator, is a gibberellin inhibitor, which can delay plant growth, inhibit stem elongation, shorten internodes, promote plant tillering, increase plant stress resistance and increase yield.Can reduce plant cell division and elongation, easy to be absorbed by the root, stem, leaf, through the wood part of the plant conducting, and transfer to close to the apex of the meristem;The fruit will not be left in the fruit due to its terminal conductivity. Paclobutrazol have a good effect in delay plant growth, restrain stem growth, short stem, promote plant tiller, increase resist-plant ability, increase yield. Paclobutrazol mainly used in rice, wheat, peanut, fruits, tobacco, oil crops, soybea, flower, grass,etc.
 
Introduction:
Paclobutrazol is a triazole plant growth regulator and an endogenous gibberellin synthesis inhibitor, which can significantly reduce apical growth advantage, reduce plant cell division and elongation, and is easily absorbed by roots, stems and leaves. It is conducted through the lignin of plants and transferred to the meristem near the apex.The fruit will not be left in the fruit due to its terminal conductivity. Applicable to food crops, vegetables, fruit trees.Promote lateral bud (tillering) breeding, stem thickening, plant dwarfing and compact; It can increase the content of chlorophyll, protein and nucleic acid.The content of gibberellin can be reduced, the content of indoleacetic acid and the amount of ethylene can be increased. The Paclobutrazol ACTS mainly through root absorption.The amount of self-leaf absorption is not enough to cause morphological changes, but can increase yield.The application of Paclobutrazol can shorten plant stem, decrease lodging and increase yield. Can be widely used in rice, soybean, rape, fruit trees, flowers and other plants.
 
Method of use:
It is suitable for grain, especially rice paddy to cultivate strong seedling and prevent lodging. It can also be used for soybean, cotton and flowers, as well as for fruit trees such as peach, pear, citrus and apple to "control and protect fruit" and make the tree shape dwarf. The plants of chrysanthemum, geranium, poinsettia and some ornamental shrubs treated with multi-effect zole were obviously adjusted and had more ornamental value.It also has obvious effect on the cultivation of greenhouse vegetables, such as tomato and rape seedling.It is mainly used with constant spray, with dosage of 105-525g per hectare.
It can inhibit gibberellin synthesis, cell division and elongation. It can control growth, dwarf plant type, improve ventilation and light transmittance, promote flowering and fruit growth.Polyazole can increase the oxidase activity of indoleacetic acid in rice and decrease the level of endogenous indoleacetic acid.The apical advantage of rice seedling was reduced and tillering was promoted.And can cultivate short and strong seedling, prevent transplant after the falling seedling, prevent lodging.Using on wheat can shorten the length of base internode, reduce plant height and enhance the anti - inversion ability.It can restrain the high growth of soybean plant and promote the branch.
 
Action method and mechanism:
It can be absorbed by plants through roots, stems and leaves.The nonabsorbable polyazole runs from the xylem to the top of the plant, mainly upwards.After leaf absorption, the leaves move slowly, and the polyazole grows all the time.This effect is mainly achieved by inhibiting the synthesis of gibberellin.By inhibiting the synthesis of gibberellin and reducing cell division and elongation, not only the amount of GA in the plant is reduced, but also the content of IAA and the content of endogenous ethylene IBA and cytokinin is increased.By changing the balance of hormones in plants, polyazole can effectively regulate and control the growth and development of plants.
 
Physiological effects are as follows
1: change the level of endogenous hormones in crops and delay the growth.
2: increase chlorophyll.The nucleic acid.Protein content, which prevents or delays the increase of light and pigment content such as aging.
3. Improve the stress resistance of plants, the use of multi-effect zole for crops, and improve the resistance to drought, cold, cold and disease.
4. Polyazole is also a kind of medicine, which can prevent diseases and insects, and has a good germicidal effect.
