Function Description The agricultural application value of Paclobutrazol is its control effect on crop growth. It has the effects of retarding plant growth, inhibiting stem elongation, shortening internode, promoting plant tillering, promoting flower bud differentiation, increasing plant resistance and improving yield. This product is suitable for rice, wheat, peanuts, fruit trees, tobacco, rape, soybeans, flowers, lawns for (plant), the use of significant results.

 

Shorten stalks of crops, then lodging-resistance

 

Inhibits the stem growth and breaks the apical dominance(inhibit the generation of Gibberellic acid)

 

Inhibits the intermode elongation, resists to lodging

 

Improves the abilities of stress tolerance

 

Promotes the lateral bud growth

 

Enhances or inhibits the photosynthesis, depends on the concentration

 

Improves the respiration intensity of root, slows down the respiration of above ground parts of crops.
Usage Recommendation Application method and dosage:

 

Cultivating strong rice seedlings: the best drug use period is 5-7 days after sowing.The appropriate dosage is 15%WP powder with 15kg of water per hectare (that is, 200g of Paclobutrazol per acre, 100kg of water), dried rice field water, evenly sprayed seedlings, that is, the concentration of 15%Paclobutrazol 500 times liquid (300ppm), plant elongation after the drug slowed down, to achieve the effect of controlling the length and promoting tiller, preventing the failure of seedlings, strong seedlings.

 

Prevent rice lodging: at the jointing stage of rice (30 days before heading), 1.8kg of 15% WP powder was applied to every hectare and 900 kg (300ppm) of water was added to evenly spray rice stems and leaves. Rice plant height could be reduced by nearly 1/3, which had an obvious effect on preventing rice lodging.

 

Rapeseed cultivating strong seedlings in rapeseed seedling three leaf stage, each hectare with 15% WP powder 600-1200 grams, 900 kg (100-200ppm) of water spray rapeseed seedling stem and leaf treatment, promote chlorophyll synthesis, improve the rate of photosynthesis, rapeseed dwarf leafy, reduce sclerotium disease, stress resistance, increase pod production

 

To prevent the soybean from growing rapidly during the first flowering period, each hectare was treated with 15%WP powder 600-1200g, 900 kg of water was added (that is, 100-200ppm), and the stems and leaves of the soybean seedlings were treated with liquid spray to control the length, increase pod and increase production

 

Control Growth of Wheat was used to mix wheat seeds for controlling the length of wheat.15% WP powder 20 grams mixed with 50 kg wheat seeds (i.e.At present, the general production of machine seeding, in the case of sowing depth is difficult to grasp, will affect the emergence rate, should not be used.

 

In the first heart stage of 2 leaves of wheat, 600 grams of 15%WP powder was applied to each hectare, 450 kg of water was added (i.e.)
Storage Keep in Dry and cool place. Store under acidic conditions,Hermetically sealed in storage
Packing Details 25kgs/drum,1kg/bag or according to customers demand.
Special Notice Strict control of the dosage. The Paclobutrazol is a wonderful plant growth retarder, the amount should be carefully set.

 

The effect of control length and keep tillers will be declined with the increase of seeding rate. The seeding rate of hybrid late rice should not exceed 30kg/acre.

 

After application, flood irrigation and excessive application of nitrogen fertilizer should be avoid.

 

Nitrogen fertilizers or gibberellic acid could be applied in the case of excessive inhibitation of seeding which was casued by high concentration.

 

Paclobutrizol have different effects on different kinds of rice and barley. When being applied, the dosage should be flexible increase and decrease appropriately.

 

After harvest, the plots must be plowed, to prevent inhibitation to the after crops.

Paclobutrazol a plant growth regulator, multi-effect azole can delay plant growth, restrain stem elongation, shorten internode, promote tiller, increase stress resistance and increase yield. It is suitable for rice, wheat, peanut, fruit tree, tobacco, rape, soybean, flower and lawn.
Function:
The agricultural application value of Paclobutrazol lies in its controlling effect on crop growth. It can delay plant growth, restrain stem elongation, shorten internode, promote tiller, flower bud differentiation, increase plant stress resistance and increase yield.
Application:
Shorten stalks of crops, then improve lodging-resistance
Application Target: Orange / Apple tree / Grape / Peach tree / Cherry tree / Lychee/Chestnut / Water melon Tomato / Eggplant / Potatoes / Radish / Peanuts / Soybeans / flowers/Wheat / Paddy /
Application:
It's used on fruit trees to inhibit vegetative growth and to improve fruit set; on pot-grown ornamentals and flower crops (e.g. chrysanthemums, begonias, freesias, poinsettias and bulbs) to inhibit growth.
It's used on rice to increase tillering, reduce lodging, and increase yield; on turf to retard growth; and on grass seed crops to reduce height and prevent lodging.
It's used to be applied as a foliar spray, as a soil drench, or by trunk injection. Has some fungicidal activity against mildew and rusts.
It's absorbed into the xylem through the leaves, stems,or roots, and translocated to growing sub-apical meristems. Produces more compact plants and enhances flowering and fruiting.
Precautions:
Paclobutrazol has a long residual time in the soil. After harvesting, the applied field must be ploughed to prevent inhibition on the post-production.
Under normal circumstances, the use of paclobutrazol is not easy to produce phytotoxicity. If the dosage is too high and the seedlings are inhibited excessively, nitrogen or gibberellin can be added to save.
Different varieties of rice are different in their endogenous gibberellin and indole acetic acid levels, and the growth potential is different. The varieties with stronger growth need to use more drugs, while the weaker varieties are less used. In addition, when the temperature is high, more application is applied, and vice versa.
