At present, there are 5 kinds of mainstream registered brassinolide products on the market: 24-mixed epibrasinolide (about 60%-70% is 22, 23, 24-epibrasinolide, about 30%- 40% are 24-epibrasinolide), 24-epibrassinolide, 28-epihomobrasinolide, 28-homobrasinolide, 14-hydroxybrassinosterol.

At present, there is only one compound called 14-hydroxybrasinosterol, which is called natural brassinolide, which is extracted from the pollen of rapeseed flowers.

1. It is forbidden to mix with alkaline pesticides and chemical fertilizers

2. Do not mix with herbicides

Brassinolide can relieve herbicide damage. If weeds absorb brassinolide, the herbicide effect will be reduced. It is recommended to use it at an interval of more than 7 days.

3. Do not spray brassinolide on the plots with vigorous growth

4. Do not spray brassinolide on rainy days or when there is rainfall within 6 hours

5. Do not use brassinolide at high temperature

6. Do not use in high concentration

7. Brassinolide is not a foliar fertilizer

1. Brassinolide + pyraclostrobin

As a fungicide of methoxyacrylic acid, pyraclostrobin has the advantages of wide bactericidal spectrum, excellent effect, safety to crops and growth promotion, etc., and the compound scheme of brassinolide + pyraclostrobin has been obtained favored by a large number of growers.

2. Brassinolide + Tebuconazole

Tebuconazole is a systemic triazole pesticide fungicide, which has three functions of protection, treatment and eradication, and has a broad bactericidal spectrum and long-lasting effect. However, tebuconazole itself has an obvious growth inhibitory effect, and if the concentration and period are not well controlled during use, it is easy to cause slow plant growth.

The scheme of brassinolide + tebuconazole can reduce the growth inhibition caused by the use of tebuconazole, and at the same time accelerate the absorption and conduction of tebuconazole by crops, so as to achieve synergistic effects and reduce phytotoxicity.
 

3. Brassinolide + potassium dihydrogen phosphate

Potassium dihydrogen phosphate is a high-phosphorus and high-potassium foliar fertilizer, which can provide high-quality phosphorus and potassium supply to crops. It can improve the metabolic level of crops when used with brassinolide, and promote the absorption, conduction and Conversion efficiency.

Using brassinolide + potassium dihydrogen phosphate in different periods can promote leaf photosynthesis, cold and frost resistance, drought resistance, dry and hot wind resistance, lodging resistance, promote flower bud differentiation, increase fruit setting rate, improve fruit quality and increase yield, etc. A variety of functions.
