PLANT HORMONES BRASSINOLIDE

Use purpose:
It is extracted from cole pollens &plant tissue, and apply to plant by sparying. Regulate the growth of plant. Best additive to
folliar fertilizers, insecticides, fungicides, herbicides.

Versatile functions:
Nine Notable Functions of Natural BR as below:
1. Promoting growth, increasing yield, improving quality.
2. Increasing the percentage of fruit setting, promoting fruit 's enlarging.
3. Increasing burliness rate, increasing weigh of fruits per 1000 granules.
4. Improving the ability of cold resistance and drought resistance.
5. Improving the ability of disease resistance.
6. Regulating differentiation in issue culture.
7. Efficiently relieve harmful effect of pesticide, fungicides, herbicides.
8. Increasing activity and energy of seeds and germination percentage.
9. Effectively prolong the duration time of natural preservation and transportation of fruits, vegetables and flowers when applied
5-10 days before harvest.

Toxicological data:
