Microbial pesticides have developed rapidly in China in recent years. Because it has the characteristics of environmental protection and health, low investment and high return, it is supported by many people. Under normal circumstances, the advantages of microbial pesticides outweigh the disadvantages, and more and more people use them. However, there are often a lot of misunderstandings when using microbial pesticides. So what is the specific misunderstanding? Let's take a look at the common misunderstandings of microbial pesticides with Xiaobian.

1. The temperature is too low

When we apply microbial pesticides, we should pay attention to the surrounding temperature and environmental factors. Many people use it not on warm sunny days, but in some low temperatures in spring and winter. As a result, the effect of microbial pesticides is not very ideal, because the temperature requirements of microbial activities are relatively high. And according to the investigation of professional data, the temperature of microbial pesticide is controlled at about 28 degrees after spraying, and its effect is much higher than that of 10-15.

2. Too dry

Application in the dry environment of application degree is also a common misunderstanding in the application of microbial pesticides. Many people will find that the effect of spraying microbial pesticides is not very good between 10:00 and 16:00 on a sunny day. This is mainly caused by low humidity, because many microbial pesticides need to be in a high humidity environment to exert their efficacy. For example, common Beauveria bassiana needs to be able to germinate spores under suitable humidity to control pests. Therefore, the application of microbial pesticides should be carried out when the humidity is high.

3. Do not avoid the light

In the application of microbial pesticides, there is no light intensity, in the strong light environment will also affect the efficacy of microbial pesticides. Because the microbes in microbial pesticides are most afraid of ultraviolet rays. Ultraviolet rays can have a fatal effect on health, and ultraviolet rays can also cause the deformation of parasporal crystals of microorganisms, thus reducing the efficacy. Therefore, we should pay attention to avoid the period of strong light to ensure the efficacy of microbial pesticides.

4. Rain after application

If microbes are exposed to heavy rain on their hands, it will basically have no effect. The spores of microorganisms have a very poor ability to withstand heavy rain. Rain Water will flush the bacterial liquid. However, if within 5 hours after spraying, if there is light rain, then it can also improve the control effect. Because light rain basically has no flushing power, it can also promote spores to germinate as soon as possible. Therefore, when using it, we should pay attention to understand the good weather forecast to ensure that there will be no heavy rain after spraying.

The above is a brief introduction to the common misunderstandings in the use of microbial pesticides. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
