Effect of paclobutrazol on flowers

For flowers that need to control plant height and prevent overgrowth, the use of plant growth regulator paclobutrazol can delay their growth. Generally for soil irrigation, can also be foliar spraying. The annual flower bed plant was sprayed with 30000 times wettable powder 1-2 weeks after seed budding, and the effect was obvious. Paclobutrazol can also be used to prolong the flowering period of some flowers. What is the application of paclobutrazol in flowers?

Paclobutrazol should be used in flowers:

Watering ① chrysanthemum with medicine can dwarf the plant. Flowerpots with a diameter of 10 cm, each pot with 15% wettable powder 2.5 mg, if the effect is not significant, apply again after 2 weeks. If the plant is as high as 1520cm, 715mg can be applied in each pot. Spraying 15% paclobutrazol wettable powder 3000 times in chrysanthemum bud stage can prolong the viewing period. After treatment, the flower diameter may be slightly reduced, but it has no adverse effect on flower color.

The indoor cultivation of daffodils by ② narcissus in winter can lead to overgrowth of plants and slender stems and leaves due to high temperature and weak light. The bulbous root field of Narcissus can be soaked with 3000 times of 15% wettable powder and sprayed with 3 times of solution, once a week for a total of 2 times, and the plant height can also be controlled.

In the early stage of ③ rose flower development (small green bud stage), spraying 15% wettable powder 2000 times liquid can prolong the flowering stage.

After ④ poinsettia cuttings were planted, 15% wettable powder was irrigated with 7500 times liquid 5mg per pot; for plants 2-3 weeks after coring, 10mg per pot was irrigated with 10mg per pot; or when the plant grew to 5 nodes, spraying leaves with 15 times wettable powder solution could make the plant dwarf, have many branches, and the leaf color was dark green.

The two-year-old potted plants of ⑤ eight Immortals were sprayed with 5000 times of 15% wettable powder, once every 10 to 15 days, for a total of 3 times, which can prevent overgrowth, compact plant shape and improve ornamental value.

⑥ Chrysanthemum morifolium was sprayed with 1500 times of 15% wettable powder once every 10 to 14 days for a total of 3 times, which can prevent overgrowth, compact plant shape, dark green leaf color and improve ornamental value.

The basal leaves of ⑦ petunia were sprayed with 3000 times of 15% wettable powder to prevent pot plants from overgrowing and compact. In order to prevent the florescence from being delayed, do not touch the flowers with liquid medicine when applying the pesticide.

⑧ Hosta, a potted plant with more than two years old and strong growth, was sprayed with 15% wettable powder 15003000x liquid, once every 10 days, for a total of 1x twice, which can make the plant compact, the leaf color dark green, and reduce the focal edge of the leaf.

The cultivated plants of ⑨ Magnolia, which are more than three years old and have strong growth, are sprayed with 15% wettable powder 150 × 300 times liquid, once every 7 to 10 days, for a total of 1 to 2 times, which can make the plant compact and improve the ornamental value.

Spraying 4g / L suspension agent 30g / L 60 times liquid of ⑩ yellow poplar can regulate the growth and dwarf of yellow poplar.
