How to identify the authenticity of pesticides and how to use pesticides rationally?

According to the efficacy, our common pesticides can be divided into insecticides, fungicides, herbicides, regulators, virus disease relief, herbicides, rodenticide, bird repellents and so on.

So how can we tell whether this pesticide product is regular or not?

First of all, we need to look at the three certificates of pesticides.

Pesticide registration certificate number

Production approval license number

Enterprise standard certificate number

The products produced by manufacturers without three certificates are irregular, so when we buy pesticides, we must look carefully, especially when buying herbicides, because if the herbicides can not be done well, problems will easily occur.

It is not easy to have these three certificates. There are many manufacturers who do not have certificates or production certificates for this product. They casually fill in the certificates of other manufacturers. In this way, how can they be distinguished? you can query and input their manufacturer's name or pesticide registration certificate number in the China Pesticide Information Network and data center.

Undocumented manufacturers, are not qualified to produce, they can also make products, however, many products are not standard.

As a result of work, I have been to the factories of more than 200 pesticide manufacturers in the past two years, there are very formal, there are only one or two production lines, a mixer, a sealing machine manufacturers, their products can actually work, but, it is easy to have problems, because their content control is not standard, in order to pursue, the effect, will often add some hidden ingredients.

For example, biological agent Helicoverpa armigera virus particles, this product, is a standard biological preparation, the use of this is absolutely pollution-free, green, but this product can only kill cotton bollworm, while the insecticidal effect is slow, some manufacturers add some hidden ingredients, the antivirus effect is fast, and can control many kinds of insects at the same time.

I know a factory owner who specializes in the production of biological agents. He said that although this biological preparation is green and pollution-free, it is very difficult to sell in China, and most of it is exported to Europe and the United States and other countries.

Therefore, when we choose pesticide products, we should still pay attention to the normality of the products. After using the same product for two years, the effect is suddenly not good. Is the manufacturer faking it?

The same product, after two years of use, the sudden effect is not good, especially insecticidal products, this phenomenon is very common.

In fact, this is really wronged the manufacturers, in fact, the manufacturers did not fake, but the insects have produced resistance to this drug. To put it colloquially, the bug has evolved to the point that this drug has no effect on it.

Many people will feel that in just two years, bugs have evolved so fast. it's too scary.

In fact, bugs don't evolve fast at all.

For example, whitefly, an adult, can produce 10 generations a year, and a generation can lay 100,500 eggs.

From the egg stage to the adult stage, it only takes 20 days.

Interested friends can calculate how many offspring an adult can produce in a year!

This is whitefly.

Therefore, when we use pesticides, we must pay attention to, exchange, use, that is, choose 2Murray three kinds of drugs to treat this bug, use them alternately, do not use one drug all the time. For those who understand pesticides, when using pesticides alternately, it is best to choose drugs with different modes of action and use them alternately. Pesticides are subdivided according to species

Score according to efficacy

Pesticides, fungicides, herbicides, herbicides, regulators, virus disease ring agents, rodenticide, bird repellent

According to the dosage form

Granule, water, suspension, EC, powder, smoke, ultra-low volume spray, soluble powder, microcapsule, etc.

Pesticides, there are pesticides, acaricides, snails, and so on.

Fungicides, there are fungicides, germicides, etc.

If you divide it in the way of action.

Insecticidal: there are contact insecticides, internal inhalers, stomach poisons, fumigants, attractants, repellents, antifeedants, sterile agents, specific insect growth regulators, etc.

Fungicides: there are inorganic fungicides, fungicides, antibiotic fungicides, etc.

When we choose pesticides, we can choose products with different modes of action to use alternately according to this.
