No pests fight drugs first

In general, no pests were found. This is because most of the insecticides currently used are contact poisons or stomach poisons, which means that they need to come into contact with the body of a pest or be swallowed by insects to enter the body. We advocate the use of drugs in the early stage of pests because it can maximize the role of pesticides and reduce the damage of plants.

Because the disease has a certain incubation period, when the plant is found to show symptoms of damage (such as leaf spots, leaf blight, etc.), the bacteria often invade the plant body for a period of time. Therefore, disease prevention is advocated in advance, but all kinds of diseases should be mastered. The timing and regularity of the occurrence of targeted injections of preventive measures.

Unexplained indiscriminate selection of drugs

Nowadays, there is a wide range of commodities in the pesticide market. It is easy to choose the wrong medicine without a certain amount of expertise. We all know that the pathogens of plant diseases are fungi, bacteria, viruses, etc. The drugs chosen for different pathogens are completely different.

If you can see that the plant has developed symptoms of disease and you are not clear about the type of pathogen, such as the use of fungicidal or bacterial medicines for viral diseases, there is no effect at all. It is not only a waste of money, but more importantly a delay in treatment time. Therefore, it is necessary to cure the disease.

Pests use the wrong medicine

Commonly used pesticides can be divided into insecticides, fungicides, rodenticides, herbicides, etc. The former two are the most widely used. Some growers are eager to treat the disease after they are found to have symptoms of the disease. Buying pesticides can even spray them many times, but the results are often not ideal. The reason is that insecticides are misused in the diseases, insecticides are misused with fungicides, and such examples are not uncommon.

Therefore, when a plant suffers from symptoms of damage, we must first judge whether it is a disease or an insect, and what kind of disease it is. If you can't diagnose yourself, it's best to ask the professional for medication.

Time is not right

Not all pests 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 their life. Enter the worm body to play a role, at this time the spray is almost difficult to work.

Therefore, multiple choices are applied during the period of no nymph in the protective layer, and this effective time is often very short. Therefore, in addition to selecting the right medicine, the time for applying the medicine should also be selected.

Do not read instructions to order medicine

Often encounter such a situation, in order to hurry to cure plant diseases and insect pests or fear of drugs is not good, at the time of dispensing arbitrarily increase the concentration of liquid medicine, so that plants are not only easy to produce drug resistance, but also easily produce phytotoxicity, is a very wrong practice . In contrast, reducing the amount of drug at random can not achieve the control effect.
