What should I pay attention to when mixing foliar fertilizers with pesticides?

Foliar fertilizer is one of the most common off-root fertilization methods, so many farmers will spray foliar fertilizer to allow plants to thrive. However, some farmers will mix foliar fertilizers with pesticides, which is also possible. However, the nature of pesticides and foliar fertilizers is not the same, and if the mixture is not reasonable, it will affect the effect of the drug.

What should we pay attention to when mixing foliar fertilizer with pesticides?

1. Pay attention to the stable traits after the foliar fertilizer is mixed with pesticides.

We need to know that after foliar fertilizer and pesticide are mixed together, there may be some adverse reactions, which will cause both to lose their medicinal properties, and even form pesticide damage. For example, many foliar fertilizers contain boric acid or ferrous sulfate, both of which are acidic. But many pesticides contain copper hydroxide, which is alkaline.

Therefore, if these two substances are mixed together, there will be some adverse reactions, which will affect the use effect. Therefore, farmers must pay attention to the acidity and alkalinity of foliar fertilizer and pesticides, if there is precipitation when the two are mixed, it means that these two substances cannot be mixed together. In fact, some experiments need to be done to see if these mixtures are undesirable chemical reactions, and to see if the precipitate changes color.

If the mixture has an adverse reaction, then do not spray it on crops. Even if there are no adverse reactions at the time, it is advisable to wait for a while to conduct experiments to see how well the crops are received before using them on a large scale.

2. Strictly control the order of foliar fertilizer and pesticide addition.

When mixing foliar fertilizer with pesticides, farmers should first dilute one drug with water, and then dilute the other drug. This is the right way, and you must not mix the two drugs together and then dilute them with water, which is not correct and may produce some harmful substances. When foliar fertilizer and pesticides are mixed, the foliar fertilizer should be diluted first, and then the foliar fertilizer diluent should be diluted with pesticides, so that the two agents can be fully mixed together to exert the best effect.

3. Drugs should be prepared and used at the same time.

In fact, some drugs do not cause adverse reactions when they are first mixed. For example, some farmers mix foliar fertilizer with pesticides, and there will be no sediment, and it seems that it can still be used, but if you leave this mixture for a while, there will be some reactions, resulting in changes in medicinal properties, which may cause some damage to crops. So if you mix foliar fertilizer with pesticides, you must use it in time and don't put it on hold.

The first note is that the properties of the pesticide are stable after the two are mixed. In fact, we all know that sometimes there will be chemical reactions between pesticides and fertilizers, if foliar fertilizers are mixed with pesticides, there is a chemical reaction or physical reaction, then it will definitely affect the normal use, and it may cause harm to crops. When we use mixing, it is best to communicate clearly with the sales staff, if it cannot be mixed, then resolutely do not mix, after all, when we grow crops, it is to make the crops grow better, not just to save trouble.

The second note, then it is ready to use. If foliar fertilizer and pesticides are to be mixed, then they should be used immediately after preparation, and should not be left for too long, because it will cause some reactions after a long time. After we use the two, then it is to save trouble, in order to have a better effect, not to put it there after matching.

Because it has been put for a long time, it is inevitable that some drug effects will be lost due to changes in the environment, or harm. <>

The third note is that you should pay attention to the proportion and order of addition. When we use this fertilizer and pesticide mixture, we should pay attention to the reference between the two in this ratio, probably how much to control a good amount, after all, the amount is easy to cause waste, the amount is less can not achieve the effect of killing, and the amount is not easy to produce pesticide damage after the amount is not good. <>

In addition, we should pay attention to the problem of this order, the problem of order should be grasped, if the order is not right, then it may lead to some reactions, affecting the effect of pesticides. Just like when we make a cake, what is added first, what is added next, what is added last, and the order is controlled, so that it will not cause the volatilization of the medicinal effect, or even lose a certain effect. For the mixing of pesticides, be sure to consult professionals, and don't be smart.

It should be noted that the mixing of foliar fertilizer and pesticides may produce chemical reactions, and if there are flocculation, precipitation, discoloration, bubbles and other phenomena after mixing, it is not suitable for mixed use.

First, it is necessary to ensure that the appearance of foliar fertilizer and pesticides is stable after mixing.

This is due to the fact that foliar fertilizers are likely to have organic chemical or physical reactions with pesticides, which can jeopardize the timeliness of pesticides or cause fertilizer damage. If the liquid has suboptimal main performance, it is not suitable for mixed application. Even if the physical properties of the liquid medicine are excellent after mixing, it is necessary to carry out small-scale experiments to see if it is very easy to cause fertilizer damage before large-scale application.

Second, the mixing order of foliar fertilizer and pesticides should be noted.

Generally, a certain amount of water is used to prepare a single dose of liquid medicine, and then use this liquid dilution to dilute another single dose; However, it is not possible to mix the two single doses first, and then dilute the solution with water to prevent the occurrence of ***, which will lead to the destruction of related components and the malignant transformation of physical properties. When foliar fertilizer is mixed, the order of foliar fertilizer and pesticide mixing is generally: foliar fertilizer, wettable powder, granule, liquid, and emulsifiable concentrate are added successively, and each one is sufficiently mixed and stirred, and then the next one is added.

3. Pay attention to the application of water flow when mixing.

Water is very harmful to the liquid medicine, and the pH and ion concentration of the water will harm the actual effect. It is better to use neutral water with low ion concentration, such as clean rainwater and river water.

Fourth, pay attention to the need to use it now.

Although the liquid medicine is not *** when it is first dispensed, it is very easy to cause a sluggish reaction after a long time, so that the drug power is missing or easy to cause fertilizer. If there are pesticide types, although they are relatively stable under the weak alkalinity standard, it is also necessary to pay attention to the current preparation and use, and it is easy to fail if it is placed for a long time.

The application of foliar fertilizer mixed with pesticides is taboo:

1. Alkaline pesticides should not be mixed with organic fertilizers such as ammonium nitrogen fertilizer and phosphate fertilizer, otherwise it will damage ammonia evaporation and reduce fertility.

2. Pesticides containing arsenic should not be mixed with inorganic salts and acetate organic fertilizers, otherwise they will cause soluble arsenic and produce fertilizer damage.

3. Alkaline fertilizers such as sodium hydroxide, lime powder, grass ash, etc. should not be mixed with pesticides such as insecticides, otherwise it will reduce the potency.

5. Chemical pesticides should not be mixed with microbial pesticides.

1. It is necessary to ensure that the appearance of foliar fertilizer and pesticides is stable after mixing.

2. Pay attention to the mixing order of foliar fertilizer and pesticides.

3. Pay attention to the application of water flow when mixing.

4. Pay attention to the need for ready-to-use and ready-to-use.

It is important to ensure that the shape of the foliar fertilizer and the pesticide is stable after mixing, because the foliar fertilizer may react chemically or physically with the pesticide, affecting the effectiveness of the pesticide or causing pesticide damage. If the liquid medicine has adverse performance, it is not suitable for mixed use. Even if the physical properties of the liquid medicine are good after mixing, a small-scale test should be carried out to see if it is easy to cause fertilizer damage, and then use it in a large area.

The order of mixing foliar fertilizer and pesticides should be noted, generally with a sufficient amount of water, a single dose of liquid medicine is prepared first.

It should be noted that when using fertilizer, you must use it according to the requirements, do not mix it casually, and if you use the liquid medicine, you should use it with it, and you can't use the liquid medicine for too long, secondly, you should also pay attention to the ratio of water and fertilizer when using fertilizer to prevent too much water and affect the role of fertilizer.

First of all, it is necessary to choose the right ratio and the right concentration, in the process of mixing, you can also add some water appropriately, you must choose the right time when spraying, and you should also pay attention to the rational use of medicine.

The mixing order of foliar fertilizer and pesticides should be noted: Generally, a single dose of liquid medicine is prepared with a sufficient amount of water, and then another single agent is diluted with this solution; It is not possible to mix two single doses and then dilute them with water.

It should be noted that some fertilizers and pesticides should not be mixed together, otherwise they will burn the crop.

Many vegetable farmers believe that foliar fertilizer works as long as it is sprayed on vegetables, but it is found that the effect is not good after frequent spraying, and sometimes even pesticide damage occurs. So how do you use it properly?

First, grasp the best fertilization period. Many vegetable farmers use foliar fertilizer to supplement nutrients to vegetables, but should master the best fertilization period, such as boron, calcium and other trace elements, it is recommended to spray at the vegetable seedling stage, which can promote the flower bud differentiation of plants, growth point development, etc. In addition, according to the physiological habits of crop leaves, the fertilization time should be selected after 6-9 a.m. or 4 p.m. on cloudy or sunny days, avoiding high temperature and strong light exposure at noon, so as to avoid liquid fertilizer evaporation too fast and affect the effect of fertilizer absorption.

<>2. Appropriately extend the time for foliar fertilizer to moisten leaves. Foliar wetting time is generally controlled at half an hour to one hour, in order to meet this requirement, foliar fertilizer can be sprayed with an appropriate amount of adhesion additives, such as some special wetting agents or adhesives, can also be neutral detergents. It reduces the surface tension of water and increases the adhesion of the solution to the leaf surface.

When spraying fertilizer, spray both sides of the leaves tightly. Since the young leaves absorb foliar fertilizer better than the old leaves, it is necessary to pay attention to keep the young leaves sprayed thoroughly when spraying fertilizer.

3. Reasonable mixing. Vegetable farmers often mix with pesticides when using foliar fertilizers, and once they are not mixed properly, they are prone to pesticide damage. Remind vegetable farmers to grasp the characteristics of foliar fertilizer and use it reasonably.

For example, chitin foliar fertilizers are easy to react with avermectin, so try not to mix them with pesticides when using; Potassium dihydrogen phosphate should not be mixed with agents containing metal ions as much as possible; Leaf fertilizer containing metal ions should not be mixed with copper-containing fungicides. Foliar fertilizer should be mixed with other agents should be diluted twice, if precipitation, discoloration, etc., should not be used to avoid pesticide damage.

Pesticide harm has always been an unavoidable topic for fruit farmers! Acids and bases cannot be mixed! Some crops are sensitive to one ingredient! Today, let's talk about the mixing order of pesticide foliar fertilizer! Can't remember the following mantra!

Foliar fertilizer pesticide mix in order! Secondary dilution to keep in mind! After putting fertilizer first, it can be divided, and the suspended emulsifiable concentrate is followed by it! Water emulsion agent at the end, stay away from the drug damage to fight monsters!

In order to supplement nutrition, please dilute a picture of organic water-soluble fertilizer and pesticide mixture first!

Because foliar fertilizers may react chemically or physically with pesticides, affecting the effectiveness of pesticides or causing pesticide damage. Water has a great influence on the liquid medicine, and the pH and ion concentration of the water will affect the effect.

You can use them together, and if you use these two together, you need to pay attention to the ratio of the two things, not too much, and also pay attention to not eating immediately after use.

It's best not to mix them together. When mixing, be sure to use proportions, and also pay attention to the order in which they are used.

What is the reason why smart bosses tend to keep their distance from their subordinates?

<> foliar fertilizer and pesticides can be mixed together, but it should be noted that pesticides with different pH and properties cannot be mixed together. When foliar fertilizer and pesticide are mixed, it is necessary to ensure that the shape of the two is stable after mixing, and there will be no adverse reactions of spring fiber growth.

<> foliar fertilizer can generally be mixed with fungicides, but it is necessary to ensure that the various properties of foliar fertilizer and fungicides are stable when using. Foliar fertilizer has many types, complex ingredients, generally contains 5-6 kinds of elements and amino acids, humic acid, hormones and other substances, when mixed with fungicides, it is necessary to strictly follow the instructions, if there is a bad phenomenon, it is not suitable for mixed use.

Foliar fertilizer is sprayed on the leaves, and if mixed, the leaves will be sprayed with herbicides. Although sometimes monocotyledon is different, it will greatly affect the growth and development of leaves.

1. Foliar fertilizer use skills.

1. When the root system of crops is senescent and the absorption capacity is weakened, apply foliar fertilizer to the soil chef.

In the late growth stage of annual crops, root activity declines and fertilizer absorption capacity decreases. If you want to apply fertilizer to crops, the root application method cannot meet the needs of crops, so it is suitable to choose soil chef foliar spray fertilizer.

2. When crops are deficient, it is necessary to apply foliar fertilizer to the soil chef.

In the process of crop growth, when it has shown some nutrient deficiencies, if soil fertilization is used, it takes a certain amount of time for nutrients to be absorbed by crops, and cannot alleviate the symptoms of nutrient deficiency of crops in time.

At this time, if foliar fertilization is used, the advantages of fast absorption of foliar fertilizer can be fully utilized, so that nutrients can quickly enter the plant body through the leaves, and the problem of nutrient deficiency can be solved. For example, when vegetables lack certain trace elements and the plant is dwarfed, and the leaves are yellowish and the nucleus is green, if the foliar spray is used to supplement these trace elements, these deficiency symptoms can be alleviated in time, and the effect is better than that of soil topdressing, and the utilization rate is high.

3. When the growth of crops is affected by adverse environmental conditions, it is necessary to apply foliar fertilizer to the soil chef.

When the soil environment is unfavorable to the growth of crops, such as too much water or drought, the soil is too acidic or too alkaline, it will cause the absorption of nutrients by the roots of crops to be blocked, and the crops need to quickly resume growth, then it is necessary to take foliar fertilizer spraying to quickly supplement nutrients and meet the needs of crop growth and development.

4. Quickly supplement medium and trace elements, and try to use foliar fertilizer from local chefs.

Some fertilizers such as phosphorus, iron, manganese, copper, zinc fertilizer, etc., if applied as roots, are easily fixed by soil colloidal adsorption, reducing the effect of use. The use of foliar spraying will not be limited by soil conditions, and has the advantages of less fertilizer, quick effect, high utilization rate, safe rubber bending, and no pollution.

5. When soil fertilization is difficult to operate, foliar fertilizer must be applied.

For crops covered with plastic film, the plots without drip irrigation belts are not paved, and it is difficult to use soil top dressing in the case of insufficient amount of bottom fertilizer, so it is necessary to choose foliar fertilizer to supplement the needs of nutrients.

However, the absorption of some nutrients in some deep-rooted crops is relatively small, and it is difficult to apply to the root absorption part if the traditional fertilization method is used, and its fertilizer effect cannot be fully exerted, while foliar spraying can achieve better results. Foliar fertilization can make crops better absorbed and utilized, which not only saves the amount of fertilizer, but also reduces the pollution of soil and water sources.
