Be careful when using brassinolide!

Brassinolide is known as the sixth category of plant nutrition regulators, which can promote crop growth, increase crop yield, and improve crop stress resistance, and can significantly increase crop vegetative growth and fruit development.

Although brassinolide has many benefits, the following aspects should also be paid attention to when using it

1. Mismatch

Brassinolide has good stability under normal circumstances and is generally not easy to decompose, but when it encounters alkaline substances, it is prone to chemical reactions and lose its activity. Common alkaline pesticides include Bordeaux mixture, lime sulfur mixture, etc., use these agents Try not to add brassinolide to avoid phytotoxicity.

2. Brassinolide ≠ fertilizer or pesticide

Brassinolide is just a plant growth regulator, it can change the process of crop metabolism, but it cannot provide nutrients for crops, nor does it have bactericidal and insecticidal effects. used together with pesticides.

3. Do not use when the crops are prosperous

Brassinolide itself promotes plant growth. Therefore, for plots with excessive growth potential and a tendency to grow vigorously, it is best to spray a growth control agent, or control water and temperature. When spraying chemical pesticides, do not Brassin lactones are added to prevent plant growth.

4. Do not use at low temperature

Under low temperature, the growth and metabolism of crops is slow, or even stops growing, and foliar spraying of brassin can not fully play a regulatory role. When the temperature is lower than 10℃, the activity of brassin will be seriously affected. When the temperature is 18-25℃, the activity of brassinolide is the highest, and the effect of regulating growth is also the best. Therefore, it is best for us to use it before the low temperature comes, generally 5 days in advance.

5. Do not use at high temperature

Foliar spraying of brassin should not be done at noon, that is, when the temperature is the highest. At this time, the leaves evaporate quickly. To prevent rapid evaporation of water at high temperature, the concentration of brassin solution will increase, which will inhibit crops to varying degrees.

6. Do not use it in rainy days

When spraying Brassinolide on crops, pay attention to the weather conditions. Do not spray on rainy days. Spraying on rainy days is equivalent to diluting the concentration of the solution again, so that the expected effect cannot be achieved.

Brassinolide is a very good plant growth regulator, but with the wrong time and method, the effect is not satisfactory. If the crop damage is too severe, the brassinolide will not be able to bring it back to life. The best time to use brassinolide can be selected in the seedling stage, before flowering, young fruit stage, swelling and color transformation stage.

 

When applying brassinolide, it is necessary to apply sufficient fertilizer and maintain a certain soil moisture, and supplement trace elements if necessary. Only relying on brassinolide will not achieve the expected effect.
