When pesticides are used , pests can't die. What can I do? The reason why pesticides can't work is that, in addition to the pesticide's own factors, unscientific use can directly affect the efficacy. There are usually the following situations:

1, no pests first fight drugs

Generally, no pests are found to fight drugs. Most of the drugs we use now are contact or stomach poisons, which means that they will come into contact with the body of the pest or be swallowed into the body by the pests.

And we advocate the use of drugs in the early stages of pests, because it can maximize the role of pesticides and reduce the degree of plant damage.

Because the disease has a certain incubation period, when we find that the plants show signs of damage (such as leaf spots, leaf blight, etc.), the bacteria have invaded the plant for a period of time. Therefore, we advocate early prevention for the disease, but we should master all kinds of diseases. The occurrence period and regularity of the occurrence, targeted advances to spray prevention.

2, the reason is unknown

Nowadays, the pesticide market is full of goods, and it is really easy to choose the wrong medicine without certain professional knowledge. We all know that the pathogens of plant diseases are fungi, bacteria, viruses, etc. Their choice of drugs is completely different.

If you see the symptoms of the disease in the plant and do not figure out the type of the pathogen, such as the use of fungicide or bacterial drugs, the virus is completely useless, not only wasted money, but more importantly delayed treatment time, often caused Serious consequences that cannot be recovered. Therefore, it is necessary to treat the disease.

3, pests and diseases do not use the wrong medicine

Commonly used pesticides can be divided into insecticides , fungicides, rodenticides, herbicides, etc. The first two are the most widely used. Some production units are eager to treat after discovering that the plant has a symptom of injury. When the pesticide is bought, it is sprayed, and even spraying several times is not effective. The reason is that the disease is misused with pesticides. Such an example is not uncommon.

Therefore, when the plant has symptoms of victimization, it is first necessary to judge whether it is a disease or a worm, and what disease is the worm. If you can't diagnose it yourself, it is best to ask a professional for guidance.

4, time is not contraindicated

Not all pests and diseases are effective when they are sprayed. This is determined by the occurrence and development of pests and diseases. For example, common scale insects have a waxy protective layer for most of the life, so that the liquid medicine It is impossible to enter the worm to play a role, and it is almost impossible to spray at this time.

Therefore, we choose to apply the drug in the initial incubation period without the protective layer. This effective time is often very short. Therefore, in addition to choosing the right medicine, it is also necessary to choose the time for applying the medicine.

5, do not see the instructions to dispense drugs

It is often the case that in order to rush to cure plant diseases and insect pests or to be afraid of drugs, it is easy to increase the concentration of the drug during dispensing, so that plants are not only easy to produce drug resistance, but also highly susceptible to phytotoxicity. . Conversely, the random reduction of the dose also does not achieve the control effect.
