There are ways to sprinkle pesticides, what are the doorways?

There is a division of labor in the art industry, professional things are left to professional people to do, no matter what things are there are some doorways, laymen will only see the excitement, in fact, insiders really pay attention to the doorway. <>

There is also some work that needs to be done before spraying, and only when it is done well can it have a better spraying effect. For pests and diseases, we sometimes can't find them at the first time, and when we do, some of them have already been damaged by pests. So for the diseased branches and leaves that have been damaged by insect pests, we should indeed deal with them at the first time, such as cutting off those diseased branches and leaves and then filling them out, or incineration outside the planting area, and then spraying pesticides, the effect will be better.

There is also a certain way to apply pesticides, not pesticides can be applied at any time, and a suitable time point should be chosen. For example, when a person applies pesticides, if he chooses to use pesticides at noon, then the effect is often not good, because noon is easy to cause this pesticide damage, and it is not conducive to the residue of the drug on the crops, so that the crops can have a longer absorption time. The temperature is too high at noon, which can easily lead to volatilization and scorch the crop, so it is not advisable to choose it at noon, but should choose it in the morning or evening.

Pesticides must be selected correctly, then it is in vain. Pesticides are divided into many kinds, some are contact killing type, some are preventive pesticides, for crops have been diseased, then when spraying pesticides, we should use contact killing type to kill some germs in a timely manner, and can not be sprayed with preventive pesticides, after all, it can not solve the problem of disease. <>

For stubborn pests and diseases, mixed pesticide treatment can be selected. Mixed pesticides can be used in combination with fast-acting drugs and low-acting drugs, which are particularly effective in sanitizing some insects that have developed drug resistance, especially red spiders, which are easy to develop resistance.

There are a lot of different pesticides with different cooking methods, according to the situation of the plant, according to the growth of the plant, there are different spraying methods, we must pay attention to our own spraying methods, pay attention to our own techniques, so that the plants can grow better.

First of all, we should pay attention to the time, but also according to different situations, try to choose the initial stage when using the drug, pay attention to the methods and skills, and be sure to avoid rainy days or hot weather.

It is best to choose local spraying, but also pay attention to the amount of liquid medicine, but also pay attention to the order of spraying, and in the configuration will generally be diluted, but also focus on spraying different positions.
