How many of the 10 common ways to use pesticides do you know?

In the field of agricultural production, pesticides play an increasingly important role in the prevention and control of pests and diseases and the improvement of crop yields. However, due to the differences in pesticides, physical properties, etc., there are various differences in the configuration and use of pesticides. There are ten common ways to use pesticides, and we will explain the following.

First, pesticides can be applied directly to crop shoots or pests. Common application methods mainly include: spraying, powder spraying, fumigation, etc.

The spray method mainly refers to diluting the pesticide water to a certain extent, and spraying it with a spraying device. At present, the use of low-volume spray is promoted, with droplets of about 100 microns; The mist machine spray is an ultra-low volume spray, with droplets in 5 75 microns, and the number of droplets is 15 times that of ordinary spray. The spray method is suitable for wettable powders, water agents, emulsions and other pesticides.

Powder spraying method is the use of powder pesticides, suitable for places where there is a lack of water sources, and is generally sprayed with a duster. The advantage is that it has high efficacy and does not require water.

Fumigation is a method used to volatilize pesticides and control pests and diseases. It has the advantages of high efficacy, fast action and no need for water.

Secondly, the pesticides used in fruits, seeds, seedlings and other propagation materials are treated with spray fumigation and dressing and brushing. It is necessary to use the appropriate treatment concentration, time and method according to the object of control.

Finally, for the application of pesticides to the soil or root areas under the crop, as long as there is spraying, watering, burrowing and injection, etc. In short, the common use of pesticides needs to be determined according to the part of the pesticide action.

The above is the common use of pesticides introduced by me according to the classification of pesticide application parts, which we can use in future agricultural production.

First of all, it is necessary to use it in rotation with other pesticides, and then you should also pay attention to the composition of pesticides, the concentration of pesticides, the combination of water and water, and the time of use, and you should also avoid high temperatures when using.

It can be sprayed directly on crops, or directly dusted, or directly flushed in water, or smoked, or directly watered, or injected, etc., these methods are more effective.

Personally, I know 5 ways to use, generally spraying, or directly powdering, or by watering, or by putting in fertilizer, or by smoking, and so on.

Soil treatment, seed dressing, spraying, powder spraying, soil burial, furrow application, injection, seed coating, etc.

They are fumigation method, wiping method, root irrigation method, pouring method, topdressing method, powder spraying method, sprayer method, poison bait method, seedling impregnation method, and seed dressing method.

These methods of use are spraying, spraying, sprinkling, splashing, root irrigation, seed dressing, seedling impregnation, poison bait, smearing, and fumigation.

I know two or three of them, you can spray pesticides on the foliage, you can spray pesticides directly with watering, or you can spray pesticides directly on the stems of plants and the roots of plants.

I don't know, although I often use pesticides, but I don't have a detailed understanding of the conventional use methods, I just protect myself when I use pesticides, and then I will choose a suitable temperature weather to use before using pesticides, but I haven't learned so many pesticide methods.

Spray method, poison bait method, powder spraying method, seed dressing method, sprinkling method, seedling impregnation method, pouring method, root irrigation method, smearing method, fumigation method.

I know that these methods are, spraying, dusting, sprinkling, root irrigation, seed dressing, etc., and these methods are very useful.

The use of pesticides is as follows:

1. Powder spraying method.

Powder spraying is the use of mechanical wind to blow low concentration or diluted pesticide powder for fine soil to the surface of crops and control objects, it is a relatively simple method in the use of pesticides. However, it is required to spray evenly and thoughtfully, so that the body surface of crops and diseases and insects and weeds is covered with a very thin layer of powder. If you touch the leaf with your finger, you can see that some medicinal powder is on your finger.

2. Spray method.

The greater the density of droplet coverage, and because the spreadability and adhesion of emulsifiable concentrate, milk powder, suspension agent and wettable agent are better than those of powder, they are not easy to be lost by rain, the residual effect period is longer, and the chance of contact with pests and diseases increases, and the better the control effect will be.

3. Poisonous bait method.

Poison bait is mainly used to control underground pests that damage the seedlings of crops and operate on the ground. Such as small ground tigers, house mice, house flies and other sanitary pests. It is made by mixing bait and pesticides that pests and rodents like to eat, and lure them to eat to achieve the purpose of poisoning.

4. Seed treatment.

There are four methods of seed treatment: seed dressing, debt erosion, seed soaking and suffocation.

5. Soil treatment method.

Pesticides are sprinkled on the soil surface or green manure crops, then ploughed into the soil, or the pesticides are applied to the roots of the plants in ditches or irrigated to kill or suppress pests and diseases in the soil.

6. Fumigation.

The toxic gas is produced by the agent, which is used to eliminate wheat moths, bean elephants, grain thieves, red bollworms, etc. in the grain and cotton stored in the warehouse under closed conditions.

7. Fumigation.

The application method of using tobacco pesticides to control pests. This method is suitable for pest and disease control, and rodent control can sometimes be used for rodent control, but it cannot be used for weed control. Fumigation is mainly used in small enclosed environments, such as warehouses, houses, greenhouses, plastic greenhouses, and large forests and orchards.
