How to use microbial pesticides correctly?

The efficacy of microbial pesticides is related to the number and activity of microorganisms. When used, weather conditions can directly affect the microbial activity in microbial pesticides, which can affect the effect. Therefore, special attention must be paid to meteorological conditions such as temperature, humidity, sunshine and rainfall.

In case of light rain, it is conducive to the reproduction of active tissues in microbial pesticides and does not affect the efficacy. However, heavy rains will wash away the drugs sprayed on crops, reducing the effectiveness of the drugs and affecting the effectiveness of control.

Microbial pesticides are most afraid of strong sunlight. Ultraviolet radiation from sunlight has a lethal killing effect on microbial pesticides. When direct sunlight is exposed to sunlight for 30 to 60 minutes, the microbial mortality rate can reach more than 50%, and ultraviolet radiation can also deform the companion cell crystal and reduce the impact on the companion cell crystal.

Do not mix with biocides. As living microorganisms, if they are mixed with fungicides, they will be killed by fungicides, lose their insecticidal and bactericidal effects, and lose their effectiveness. Viral microbial pesticides are highly specific.

In general, they are only effective against one pest and have no effect on other pests. For example, diamondback moth particle virus can only be used to control diamondback moth. Investigate the occurrence of pests in the field before use, reasonably arrange the control period according to the occurrence of pests, and use drugs in time.

Dilute the microbial preparation with a small amount of water, put the seeds in it, stir well, and place in a cool place to dry. Soak the seeds, dilute the microbial preparation with a small amount of water, and put the seeds in it for about 6-12 hours before sowing. Seed dressing and soaking can be used for fruit tree rootstock seedlings.

Soak the roots, water the roots, soak the roots, dilute the fungal agent with a small amount of water, and dip the roots of the seedlings washed away from the root nutrition into the dilution solution so that they are completely stained with the bacterial solution. Root irrigation, where the seedlings are immersed in the roots for cultivation, and then the remaining bacterial solution is used for root irrigation culture.

It is strictly forbidden to use with herbicides, insecticides, fungicides, and other insecticides, which can reduce the activity of bacteria or even kill beneficial bacteria directly. Microbial fertilizer can be used as both base fertilizer and top dressing in fruit tree planting, and the effect is also very good.

Correct use of microbial pesticides: the principle to be grasped, there are microbial pesticides, the efficacy of microbial pesticides, related to the number and activity of microorganisms, the use of weather conditions will directly affect the microbial activity in microbial pesticides, thereby affecting the effect, therefore, in the use of temperature, humidity, sunshine and rain and other meteorological conditions.

Properly dilute the microbial pesticide in the ratio stated on the instructions and then spray. Pay attention to avoid the temperature being too high or too low, refer to the manual for specific temperatures; It should not be used in a dry environment; Avoid bright light.

Pesticides should not be used in live water that is easily turbid. Due to the large number of impurities in the living water, especially the water in the ditch with large sand content is more likely to block the sprinkler head, and it will also destroy the suspension of the liquid medicine and produce precipitation.

The amount of pesticides should not be increased or decreased at will. It is necessary to strictly follow the instructions or the recommended dosage of agricultural technicians, too little medicine has no effect, too much use of drugs may produce pesticide damage and increase pesticide residues in agricultural products, which will increase the cost of use.

Introduction: With the continuous updating of science and technology, the society is also constantly progressing, and there is a certain amount of involvement in various fields, and science and technology are also very important for the development of these fields, such as the use of science and technology in agriculture can effectively increase yields, and can also ensure some problems in quality, so as to increase some income of farmers, which is very important for agricultural development. Therefore, in the process of agricultural development, we must make correct use of science and technology.

One of the most important items is the use of microbial pesticides.

1. Regarding microorganisms in daily life, the advantages of microorganisms include the characteristics of low toxicity and low toxicity. For some users, it is not particularly easy to produce poison, and it is also very beneficial to the growth of crops, and the degree of pollution to the land is also small, so that it will not destroy the ecological balance. In the case of crops, there is no corresponding resistance.

But there are also some disadvantages, such as microbial pesticides, in general, only have a certain effect on one pest.

Second, standardize the use of microbial pesticides, first of all, we must avoid the use of microbial pesticides in the case of low temperatures, otherwise, it will not achieve a certain prevention and control effect. The requirements for air humidity are also relatively large, and it is best to choose to use it in some cases of cloudy days or high humidity, which can also make the control effect of pesticides better. If heavy rain washes away, it will also reduce the effectiveness of microbial pesticides, so be sure to pay attention to the weather forecast when using them.

In the process of use, it is necessary to avoid high temperature or strong light exposure, which is easy to reduce the efficacy of the drug.

3. PrecautionsRegarding the use of microbial pesticides, some staff must pay attention to personal protection in the process of use. Because this may have some adverse effects on our body unintentionally, in the long run, it will make the body suffer some fatal blows, so it is very necessary to do a good job of relevant protection, which requires the preparation of some professional protective tools and so on. In the process of casting, you should also pay attention to the rational use, otherwise it will reduce the effectiveness of the drug, and thus the benefit will be reduced.

According to the proportion of use, a disadvantage and late to follow the professional proportion, the effect of the pesticide prepared in this way will be particularly good, so that the microbial pesticide can play a greater effect.

When using the silver should also be controlled temperature, generally in some moderate temperature can go to the umbrella, not less than 10, in the high temperature or in the Zhengling noon natural gas can not be used to use, must be cloudy or at 5:00 p.m. to use, in order to improve the use effect.

First of all, it is necessary to understand the basic ingredients of this pesticide, and also need to choose suitable crops according to pesticides, and must pay attention to the ratio when using pesticides.

First of all, we should choose some good quality microbial pesticides, but also should pay attention to the way of storage, when using should also dig reeds to avoid rainy days noisy, should choose sunny days to use, so that it will not affect the effect, when using should also wear a good lifting and dispersing protective clothing, avoid contact**.

When making a friend use, we should pay attention to the temperature per mu, and we should pay attention to the humidity of the soil, the concentration of pesticides, and also match with water, and we must grasp the proportion.

People to food for the day, I believe this sentence we have heard, even now is the high-tech information age, but the development of agriculture country also attaches great importance to, after all, agriculture is to solve the basic problem of food and clothing for our human beings, so agricultural pesticides are also constantly researched and developed, the latest is microbial pesticides, people will also be confused about the use of microbial pesticides to help us? This is a great improvementAfter all, it can go deeper into the soil, and this is alive, and it can achieve a better regulating effect, which is very recommendable, let's analyze it specifically.

First of all, we must know that those pesticides in the past have chemical components, in fact, these chemicals are used to restrain pests, but they are poisonous drugs, and there are more or less pesticides for the plants and soil they plant, so even if they buy pesticides from the market, at this time, they must first take a look at whether they are suitable for their own soil use, conduct some experiments, and not directly use them on a large scale, but now microbial pesticides are different, this is not a chemical substance, but relies on microorganisms, This is a living being, which we can understand as a creature that nature itself has.

Even if they enter the soil, there will be no problem, and the adaptability will be very good, in the agricultural development of adaptability is also a very key factor, any pesticide entry, if the adaptability is not good, it will lead to great harm to these soils, even if the plant grows well, but for the soil will also be a big problem.

So we can not underestimate these, science and technology are constantly developing forward, but to achieve a qualitative breakthrough, a new design is needed, for pesticides, microbial pesticides is a new design innovation, must have a greater effect, so I myself is more recommended to use, but be sure to look at the description, do not think that it is a microbial pesticide to use casually.

It is particularly helpful, so that it will not lead to the production of pesticide allergies, and at the same time will not harm **, and then it can also increase the yield of food, and then it can also stabilize the price level, and it can also ensure the composition and value of the concentration.

It can make many plants not attacked by insects, make the number of plants **, make the quality of plants better, change the quality of the soil, and make the price of many things stable.

It helps a lot. First of all, it can improve the growth and development of crops, increase the growth rate, increase the yield, and also improve the harvest of farmers, and obtain very good economic benefits.

Today's microbial pesticides are not chemicals, but rely on microorganisms, which are living beings, and we can understand them as living organisms that nature itself has.

Even if they enter the soil, there will be no problem, and the adaptability will be very good, in the agricultural development of adaptability is also a very key factor, any pesticide entry, if the adaptability is not good, it will lead to great harm to these soils, even if the plant grows well, but for the soil will also be a big problem.

So we can't underestimate these, science and technology are constantly developing forward, but if you want to achieve a qualitative breakthrough, you need a new design, for pesticides, microbial pesticides are a new design innovation, must have a greater effect, so I myself is more recommended to use.

In the past, chemical pesticides played a positive role in the prevention and control of pests and diseases for farmers in agricultural production, but chemical pesticides were gradually "ignored" without people's pursuit of green and healthy food. Chemical pesticides have the disadvantages of high residues, high toxicity, easy to contaminate food, endanger human health, and destroy ecological balance. In the early years, people often had food poisoning and spraying poisoning, and they were taken to the hospital for emergency treatment, and some farmers even lost their lives.

What should I pay attention to when using pesticides by microorganisms?

Appropriate and timely medication. Different pesticide varieties have different control effects on different control and Dan Songxiang. Before administering medicine, we must conduct a careful investigation of pests, diseases and weeds.

Before applying pesticides, field efficacy tests are done to test the efficacy of suitable pesticides and crops. During the test, pay attention to avoid unfavorable climatic conditions such as high temperature periods, high humidity times, low temperature periods and rainy days. Greenhouse spraying is used.

You can use the method of heating in the greenhouse, such as spraying in good weather and sunny days, if the climate is humid, you can use a sprayer in advance to spray the liquid evenly on the back of the leaves.

The amount of liquid medicine can not be too much, and the amount of liquid medicine is generally multiple of the amount of liquid medicine contained in each kilogram of greenhouse. According to the weather conditions, the amount of spraying is related to the length of medication time, temperature, rain, humidity, some places have a dry climate, and the dilution of the liquid medicine is slow, so the spraying time may be later or even postponed for more than 2 hours, or the number of spraying times is reduced, or the medication time is shortened or even no longer used, which may lead to the residual liquid amount of medicine can not reach 50% of the original dosage.

A high-pressure sprayer is used to apply the drug. The specifications and configuration of the sprayer are determined according to the type, agent and control objectives of diseases, insects and weeds, and the high-pressure sprayer can be used generally, or the low-pressure sprayer can also be used, or according to the degree of occurrence of diseases, insects and weeds. When spraying, it is necessary to pay attention to the nozzle can not leak the spray, or not to leak the liquid medicine, and not to directly contact the liquid medicine with your hands.

Ying Xiang briefly replied that the temperature should not be too high when using, otherwise the microorganisms will be inactivated, and be careful not to mix it with other pesticides, and use it under certain humidity conditions.

First, the use of the principle of grasp.

The efficacy of microbial pesticides is related to the number and activity of microorganisms, and the weather conditions will directly affect the microbial activity in microbial pesticides, thereby affecting the effect, so special attention must be paid to meteorological conditions such as temperature, humidity, sunlight, and rain when using bright and bright.

2. Temperature. The activity of microbial pesticides is directly related to temperature, and the suitable temperature for application should be 20-30. Some vegetable farmers do not pay attention to environmental factors when using microbial pesticides, but choose to use them in cold weather conditions with low temperatures, or even in cold weather conditions in winter and early spring, so the expected control effect is not achieved.

Precautions: If the temperature is lower than the appropriate temperature, the biological pesticides sprayed will have a slow reproduction rate in the body of the pests, which is difficult to play a role, resulting in poor efficacy of the product. The control effect of microbial pesticides under 20-30 conditions is 1-2 times higher than that at 10-15 conditions.

Therefore, when applying pesticides, it is necessary to choose a suitable temperature for use.
