Benefits and methods of secondary dilution of pesticides

Pesticide is a kind of weeding and disinfection articles that need to be used in planting and production. When using pesticides, the secondary dilution of pesticides is also very familiar to many farmers. Basically, most pesticides have to be diluted twice, and secondary dilution of pesticides is now strongly encouraged. So what are the benefits of secondary dilution of pesticides? How should it be carried out? Let's take a look at the benefits and methods of secondary dilution of pesticides with Xiaobian.

First, dilution benefits

1. Ensure uniform dispersion of pesticides.

In the use of pesticides, if some wettable powder or powder particles are put directly into the water tank without dilution. Then this kind of pesticide will form agglomerates and sink directly to the bottom, and it is not very convenient to stir after sinking. Therefore, if there is no secondary dilution, the pesticide will not be fully dispersed due to uneven mixing. As a result, the concentration of the solution is uneven, and the uniform spray can not be guaranteed. Therefore, the second dilution of pesticides can effectively disperse them and ensure uniform spraying.

2. Ensure accurate drug use

Over the years, our agriculture has developed very fast. It also greatly reduces the use of pesticides. In general, the amount of pesticides used in an acre of land is only about ten grams, sometimes even lower. Therefore, the amount in each sprayer will be less, and if the second dilution is carried out at this time, the accurate use of the drug can be more guaranteed. For example, our commonly used XXX herbicide generally uses about 8g per mu. After mixing with water, each barrel is basically only two grams, if it is a preparation, it is not guaranteed to accurately weigh, and can not be evenly diluted.

3. Reduce the risk of poisoning

No matter what kind of pesticide it is, it has strong toxicity. If the second dilution is appropriate, the possibility of exposure to the original drug can be reduced as much as possible. Especially for some very toxic pesticides, if it is a dilution, then the chance of exposure to the original drug can be as many as four times or more. And if the second dilution, then basically only once. Therefore, the risk of pesticide poisoning can be greatly reduced, and the pesticides exposed in the later stage are also prepared mother liquor, and the poisoning probability is also very small.

2. Dilution method

First of all, we have to choose a graduated medical salt water bottle or some small containers. Then put the pesticide into the container and inject the appropriate proportion of water to prepare the mother liquor. Then if there is a strong suspending agent, then the medicine adhered to the package should be cleaned in time. Then stir the agent to dissolve it in water. Then the second dilution is carried out according to the spraying method, and if it is a knapsack spray, it can be diluted by pouring it directly into the medicine bucket. First, add the right amount of water to the medicine bucket, then shake it well, and then add the right amount of water to mix it well. If it needs to be used in a large area, a large container should be used for the first dilution, and then the second dilution should be carried out in the medicine bucket.

The above is a brief introduction to the benefits and methods of secondary dilution of pesticides. In the preparation of mother liquor, we should pay attention to strictly control the amount of water and liquid medicine, ensure the quality of dilution, and avoid the decline of prevention and control effect. That's all for today's introduction. Thank you for your reading and support.
