Brassinolide is internationally recognized as the sixth largest plant hormone. It has the functions of promoting growth, improving stress resistance, increasing yield and product quality, synergistic enhancement and eliminating pesticide damage. It is widely used in dozens of major crops such as oil and grain crops, fruit trees, and vegetables.
3 misunderstandings about brassinolide
1. Mistakenly believed to be foliar fertilizer
In fact, brassinolide is not a foliar fertilizer. Brassinolide itself has no nutrition. It indirectly regulates crop growth by regulating the plant endogenous hormone system and has good compatibility with foliar fertilizer.
2. Mistakenly believed to be dispensable
Many people mistakenly believe that brassinolide is optional. In fact, brassinolide has comprehensive functions. It can be used throughout the crop process from seed treatment to harvest. It has strong effects on stress resistance, quality improvement, yield increase, and comprehensive synergy enhancement. Moreover, brassinolide has no drug resistance.
3. Mistakenly believed to be a niche product
A senior industry insider said that the current domestic market capacity of brassinolide is about 1.2-1.5 billion yuan, and it is expected to reach 2 billion yuan in 5 years. With the market's understanding of brassinolide and the in-depth development of its functions, it will become a billion-level product in the future!
Five major functions of brassinolide
1. Root promotion in the seedling stage
Used as seed treatment or spraying in the seedbed stage, it has a significant growth-promoting effect on the root system of seedlings, with deep roots and lush leaves, and strong seedlings.
2. Growth promotion in the vegetative period
It has the dual effects of promoting cell division and cell elongation, and can also increase the content of chlorophyll in leaves, enhance photosynthesis, and increase the accumulation of photosynthetic assimilation products. Therefore, it has a significant effect on promoting plant vegetative growth and can increase crop yields.
3. Fruiting promotion in the reproductive period
Brassinolide can increase the germination rate of pollen, promote the elongation of pollen tubes, and is beneficial to plant fertilization, thereby increasing the fruiting rate and fruiting rate. During the maturity period of crops, the number and weight of grains increase, and for fruits and vegetables, the fruit is uniform, which improves the quality of crops.
4. Enhance stress resistance
After entering the plant body, brassinolide not only strengthens photosynthesis and promotes growth and development, but also stimulates the activity of certain protective enzymes in the plant body, which can greatly reduce the harmful substances produced by the plant body under adversity, especially in terms of drought resistance and low temperature resistance.
5. Alleviate pesticide damage
When herbicides, fungicides and insecticides are used incorrectly or when the concentration ratio is inappropriate, pesticide damage is likely to occur. Timely use of brassinolide + high-quality foliar fertilizer can regulate nutrient delivery, supplement nutrition, reduce damage, and accelerate the recovery of crop growth.
Five major combinations of brassinolide
1. Brassinolide + pyraclostrobin
Pyraclostrobin, as a methoxyacrylic acid fungicide, has the advantages of a wide fungicide spectrum, excellent effect, safety for crops and growth promotion. The combination of brassinolide + pyraclostrobin has won the favor of a large number of growers. Its advantages are: synergistic effect, strong rapid effect; enhanced disease resistance, reduced drug resistance; promoted growth and reduced pesticide damage.
2. Brassinolide + tebuconazole
Tebuconazole is a systemic triazole pesticide fungicide with three functions of protection, treatment and eradication. It has a wide fungicide spectrum and a long lasting effect. However, tebuconazole itself has a very obvious growth inhibition effect. If the concentration and period are not well controlled during use, it is easy to cause slow plant growth. The brassinolide + tebuconazole solution 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, which has the effect of synergistic effect and reduced pesticide damage.
3. Brassinolide + glyphosate
Glyphosate is a conductive herbicide. This type of herbicide can be absorbed by the roots, stems, leaves, bud sheaths and other parts of the plant, and can be transmitted in the body of the plant. The reason why glyphosate can kill weeds is that the liquid is absorbed from the leaf surface and then transmitted to the roots, causing the weeds to die slowly. If the weeds encounter a low temperature environment, the metabolism of the weeds is slow, and the absorption and transmission of glyphosate are slow, and the weed control effect will be greatly reduced. The use of brassinolide with glyphosate can improve the metabolic level of weeds and improve the weed control effect.
4. Brassinolide + potassium dihydrogen phosphate
Potassium dihydrogen phosphate is a high-phosphorus and high-potassium foliar fertilizer, which can provide crops with high-quality phosphorus and potassium elements. Used with brassinolide, it can improve the metabolic level of crops and promote the absorption, conduction and conversion efficiency of potassium dihydrogen phosphate. Using brassinolide + potassium dihydrogen phosphate at different times can promote leaf photosynthesis, cold and frost resistance, drought resistance, dry hot wind resistance, lodging resistance, promote flower bud differentiation, increase fruit setting rate, improve fruit quality and increase yield.
5. Brassinolide + 920
920 is the common name for the plant regulator gibberellic acid. It has the functions of promoting seedling growth, fruit enlargement, and elongating fruit ears on crops. However, improper use can easily lead to adverse consequences such as crop elongation, excessive nutrient growth, and fruit deformity. The combination of brassinolide + 920 can reduce the risk of phytotoxicity caused by using 920 alone. Brassinolide can balance the endogenous hormones of crops, enhance crop photosynthesis, promote balanced crop growth, and normal fruit expansion.
Brassinolide is highly safe and effective. It can be used in various crops at various stages. After years of promotion and application, many excellent compounding solutions have been produced.
Limitations:
1. Brassinolide is a chemical substance with a biomimetic sterol structure. It has a certain suitable concentration for use. If the concentration is too high, it will not only cause waste, but also may inhibit crops to varying degrees.
2. The effect is obvious under adversity, so the effect is not good when the crop grows well.
3. Some manufacturers unilaterally exaggerate the efficacy and activity of their own products, resulting in a great difference between the actual effect and the publicity effect after farmers use it. This has invisibly seriously hindered the further development of the brassinolide market.
4. The effect of brassinolide cannot be exaggerated. If the crop is too severely damaged, it cannot achieve the effect of reviving the dead. In addition, it must be used in combination with other pesticides and cannot completely replace it.
5. Brassinolide itself has no nutrients, so the nutrient supply must be guaranteed, and "water, fertilizer, and conditioning" must be integrated so that brassinolide can play a better role in the plant.
In short, brassinolide has certain limitations. It cannot be used casually because it has many advantages. We should have an objective attitude towards any product and use it in a scientific and reasonable way so that it can play its due role.
