Correct methods for using brassin and precautions
Brassin is a plant growth regulator. Many farmers often spray some plant growth regulators when growing crops, which is fairly common, but once used incorrectly, it will cause great losses. Below, the editor explains the precautions for using brassin. Let's take a look together.
1. When brassin must not be sprayed
As a commonly used plant growth regulator, brassin is not suitable for use in three periods. First, when mixed with pesticides or fertilizers, note that it must not be mixed with alkaline substances. Second, do not apply it on rainy days. Summer weather is changeable, so when spraying brassin, be sure to observe the weather conditions. It must not be sprayed on rainy days, because spraying on rainy days will dilute the solution concentration again, thus failing to achieve the expected effect. Third, do not use it in high temperatures. When spraying brassin on leaves, do not choose noon when the temperature is highest, because at this time the leaves evaporate quickly; first, it is not easily absorbed by the crops, and second, it also prevents evaporation from increasing the solution concentration.
2. When it can be used
Brassin is generally sprayed and used during three stages of crops. First, at the flowering stage, spray it one week before the crops' melons and fruits bloom to promote the number of flowers, improve pollination and fruit setting rate, and lay the foundation for high yield. Sometimes plants grow slowly when setting fruit after flowering. In this case, brassin can be sprayed appropriately to promote the growth of young fruit and speed up the absorption of nutrients. Spraying brassin during the fruit expansion stage is an important measure to increase yield, but note that from fruit setting to the end of expansion, including the coloring and ripening stage, sufficient nutrients must first be ensured. Nitrogen, phosphorus, potassium, and trace elements are indispensable; otherwise, only spraying brassin will not achieve the expected effect.
3. Precautions for use
It cannot be applied in time when it rains. If it rains within 6 hours after spraying, it must be sprayed again. The best time to spray the agent is before 10 a.m. and after 4 p.m. When spraying pesticides, wear protective clothing according to the operating instructions. When spraying, wear a mask and gloves properly, and do not eat during this period, otherwise it will harm your health. After use, packaging bags and tools must be properly disposed of.
