How is copper fungicide used in pesticides?

It is necessary to choose the appropriate fungicide according to the situation of the crop, do not mix it with other fungicides, and pay attention to avoid the temperature or humidity when the temperature is relatively high, the humidity is relatively large, and the wind is relatively strong.

When you choose the right time, you can dilute it and spray it, and you can apply it reasonably, which can better protect the plant and provide the elements.

This needs to be diluted so that it can continue to be used, or it can be used with other pesticides, so that it can have a better effect.

It can be used in combination with pesticides, can also be used in adulteration with pesticides, and can also be mixed with other insecticides.

Quinoline copper is mainly used in tomatoes, peppers, cucumbers, zucchini, potatoes and grapes and other plants, and has a good control effect on late blight, blight, blight rot, downy mildew, etc.

It can also be used for wheat seed dressing to control smut.

Quinoline copper is a quinoline low-toxicity protective fungicide, which is an organic copper chelate.

Broad-spectrum blind, efficient, low residue, safe to use, against fungi.

Sexual and bacterial diseases have good preventive and advanced effects.

After spraying, a tight protective film is formed on the surface of the plant, and the slowly released copper ions are destroyed.

Inhibit the germination and invasion of germs, so as to achieve the purpose of disease prevention and treatment.

It is mainly lime sulfur mixture, which is used for insecticide and virus killing.

Can copper hydroxide be used as a bactericidal drug for kiwifruit?

Probably.

It should be possible. Probably should.

Probably should.

When using fungicides, the first should be diluted, try to put the nozzle slightly lower when spraying pesticides, and try not to choose to spray pesticides in windy or rainy weather, and the lead is bright and the amount of pesticides is not too wide.

First of all, it is necessary to choose the appropriate medication method according to different periods, and then it is also necessary to pay attention to the need for proportion, avoid rainy days or eggplant ants are relatively high temperature ratio, and also choose some professional instruments. It is necessary to do a good job of protection.

Pay attention to the spraying time, this fungicide also has its own characteristics, and it is also resistant to rain, it cannot be used for a long time, and it should be used at intervals.

You can understand the efficacy of this fungicide, and at the same time, you can also grasp the specific prevention and control methods, and use it according to the specific situation.

If the fungicide has a special destructive effect on mycorrhizal fungi, it is necessary to apply the fungicide before or after 3 weeks after the use of mycorrhizal fungi.

Copper preparation is a fungicide that has been used in agricultural production for hundreds of years, mainly used to prevent and control some diseases of crops. Through the heavy metal characteristics of copper ions, the proteins in the pathogen cells are denatured and inactivated to achieve the purpose of preventing and controlling crop diseases. Copper preparations are mainly divided into two categories, namely inorganic copper preparations and organic copper preparations.

Inorganic copper preparations include Bordeaux liquid, copper sulfate, cuprous oxide, copper hydroxide and other copper preparations; There are relatively few types of organic copper preparations, and the life of occurrence is relatively short, including several copper preparation products such as copper luoami, copper succinate, copper pinesinate, copper acetate, etc.

For inorganic copper preparations, they are basically in a weakly alkaline state. Therefore, it cannot be mixed with weakly acidic foliar fertilizers, fungicides, insecticides and plant growth regulators; At the same time, copper ions are also easy to antagonize with phosphorus, nitrogen, iron and manganese and other elements, so it is not recommended to mix inorganic copper preparations with other foliar fertilizers. It is still easy to judge the antagonism of copper ions, and the characteristic blue color of copper ions is the most obvious sign.

If it changes color, it means that there is a situation of antagonism. It is precisely because the scope of inorganic copper preparations mixed with other pesticides is too narrow, resulting in the effect of inorganic copper preparations in preventing and controlling diseases is somewhat discounted. It is also the reason why many farmers have a headache when it comes to copper preparations.

For organic copper preparations, such as copper ammonia, copper succinate, etc., there has been a qualitative leap in the application rate, application effect, adaptability, safety and inorganic copper preparations. At the very least, the safety of mixing with other pesticides and plant growth regulators has been greatly improved, and the scope of mixing and matching has also expanded a lot. This has great advantages for organic copper preparations, as opposed to inorganic copper preparations.

Organic copper has good mixability. In general, inorganic copper cannot be mixed with pesticides containing "metals". If it cannot be mixed with mancozeb, mancozeb, manganese and other drugs containing these ingredients, nor can it be mixed with foliar fertilizers containing "metals".

Metal ions can cause the sedimentation of suspensions and suspensions, change the efficacy of the drugs or cause drug damage. Because the metal ions in the copper and various pesticides may also cause this reaction, the situation of copper preparations in the mixing becomes more complicated, and it is more difficult to predict whether there is pesticide damage. Most copper formulations should also not be mixed with thiophanate-methyl (methyl tobuzin), carbendazim, and ethyltrimencarb-containing pesticides.

Therefore, when the situation is unclear, a preparatory test should be done, that is, mixed first, to see if there is a chemical reaction phenomenon such as changing the color of the liquid and the color of the pigment, producing bubbles, producing precipitation, or changing the colloidal suspension and causing the delamination of the potion, once these phenomena occur, they cannot be mixed. Or you can also test spray on the vegetables first, and then mix them in a large area when you are sure that there is no pesticide damage.

The use of copper solution for agricultural limb loss medicine, to control the pH below 6, otherwise it is easy to absorb some metal ions into the plant, followed by pay attention to the fertilization of multiple sheds, the use of low-density fertilization methods. Empty destruction.

It is necessary to choose the most cost-effective and suitable pesticides according to the varieties of crops that are clear to farmers, and they can also be mixed with other pesticides when they are used too early, and then they must pay attention to the distance, and they must pay attention to the composition and concentration of pesticides.

It can be used according to the combination of varieties, or according to the specific pesticide effect, and pay attention to the prevention and control effect of pesticides.

Summary. Medium elemental fertilizer.

Calcium: The application of lime in calcium-deficient soil can not only make plants and soil obtain calcium supplementation, but also increase soil pH value, thereby reducing or eliminating the harm of a large number of iron, aluminum, manganese and other ions in acidic soil to soil properties and plant physiology.

Magnesium: Magnesium is one of the main components of chlorophyll in plants and is involved in the photosynthesis of plants.

Sulfur: Sulfur promotes nodule formation in leguminous plants and increases nitrogen fixation capacity.

Silicon: Silicon fertilizer increases crop photosynthesis and chlorophyll content, makes stems erect, and promotes the accumulation of organic matter. It can also provide pest control capabilities for crops.

Can copper preparation fungicides be used together with medium and trace element fertilizers.

OK. Most copper preparations should also not be mixed with thiophanate-methyl (methyl tobuzin), carbendazim, and acethocarb-containing pesticide residues. If the color is changed, bubbles are produced, precipitation is produced, or the colloidal suspension changes and chemical reaction phenomena such as the stratification of the medicinal eggplant liquid, once these phenomena occur, they cannot be mixed.

Copper preparations should not be mixed with pesticides containing several "metals" or foliar fertilizers containing "metal" base rents, such as mancozeb, mancozeb, fomeibis, etc., and drugs containing these ingredients. Because the two will have a chemical reaction, causing the sedimentation of the suspension agent and the suspension agent, which will change the efficacy of the drug or cause drug damage. However, at present, some copper preparations of potato fibrillator can be mixed with other drugs containing metals due to their relatively stable properties.

Most copper preparations should also not be mixed with thiophanate-methyl (methyl tobuzin), carbendazim, and acethocarb-containing pesticide residues. If the color is changed, bubbles are produced, precipitation is produced, or the colloidal suspension changes and chemical reaction phenomena such as the stratification of the medicinal eggplant liquid, once these phenomena occur, they cannot be mixed.

Medium and trace element fertilizers also contain elements such as zinc and iron, which will not produce oxidation reactions.

If it does, it will <>

Then you told me that you could mix them.

I thought yours was the kind that didn't have.

If some of them are contained, they can't be used, and there will definitely be a reaction.

Especially the reactive metal of iron and zinc.

Don't you even know about medium and trace element fertilizers?

Medium element fertilizer calcium Libu cherry: The application of lime in calcium-deficient soil can not only make plants and soil obtain calcium supplementation, but also increase soil pH value, thereby reducing or eliminating the harm of a large number of iron, aluminum, manganese and other ions in acidic soil to soil properties and plant physiology. Magnesium:

Magnesium is one of the main components that make up the chlorophyll limb plexus in plants and is related to photosynthesis in plants. Sulfur: Sulfur promotes the formation of nodules in leguminous plants and increases nitrogen fixation capacity.

Silicon: Silicon fertilizer increases crop photosynthesis and chlorophyll content, makes stems erect, and promotes the accumulation of organic matter. It can also provide pest control capabilities for crops.

Pro, if it contains sulfur, silicon will not react.

Understand? Generally, trace element fertilizers contain elements such as zinc and iron.

Pro, some contain sulfur, silicon <>

Calcium and magnesium are reactive metals.

When using copper-containing fungicides, it is necessary to pay attention to the concentration, combination of fungicides, how to use, frequency of use, and safety. The following is elaborated:

1. The concentration and combination of copper-containing fungicides.

When using copper-containing fungicides, it is necessary to pay attention to the concentration problem, if the concentration of the aqueous solution of copper-containing fungicides is too low, it will not play the role of sterilization and insecticidal eggs. If the concentration is too high, the copper-containing biocide will not be completely dissolved and cause waste, generally speaking, the concentration of 1 to 7 is just right. Copper-containing fungicides can kill bacteria and eggs, and sometimes other fungicides are used in combination to enhance the effect, but remember not to mix with other metal-containing fungicides, such as zinc-containing fungicides, because the two metal ions will react and turn the aqueous solution into an emulsion-like suspension, so it cannot be used.

2. The use method and frequency of copper-containing fungicides.

Copper-containing fungicides mainly rely on copper ions and other active ingredients to kill bacteria and insect eggs, and cannot kill weeds and cannot play the role of weeding, so it is necessary to pay attention to spraying on the branches and leaves of crops when using. Copper-containing fungicides are as effective as they do not affect the roots or soil of crops, so you can use them with confidence, as long as you remember to spray them on the branches and leaves as much as possible.

Because the dissolving agent of the copper-containing fungicide is volatile, if the dissolving agent is volatilized or the water is evaporated, the copper ions cannot play a bactericidal role, so the water will be sprayed again the next day after spraying the copper-containing fungicide, and the residual copper will be turned into copper ions. Copper-containing fungicide is then sprayed every three days to ensure a continuous kill of eggs and bacteria.

3. The safety of copper-containing fungicides.

Copper-containing fungicides are relatively safe, and the toxicity comes from the heavy metal toxicity of copper ions, so you should still be careful, put out of the reach of children, and rinse with plenty of water if it comes into contact with it.

The above explains the problems that need to be paid attention to in copper-containing fungicides from various aspects such as principle, use method and safety.

We must pay attention to the efficacy, we should choose the right agent according to the crop, we must prescribe the right medicine, we should pay attention to the ratio between pesticides and water, and we should pay attention to the appropriate time.

You need to pay attention to the method of use, you need to pay attention to the rules of use, you need to pay attention to the mode of use, you need to pay attention to the skills used, you need to pay attention to the need to protect your health when you use it, and you also need to wash your body after use, these are all issues that need to be paid attention to.

It is necessary to pay attention to personal protection, to prevent poisoning, but also to grasp the concentration of fungicides, and to pay attention to the surrounding environment, to ensure the humidity of the air.

Pay attention to the instructions for use, but also pay attention to the contraindications, but also pay attention to the situation of use, avoid the critical situation, and pay attention to the proportion of moisture.

Can basic copper sulfate be mixed with pesticides and other fungicides?

Hello dear, basic copper sulfate is a fungicide that can be used to control plant diseases. However, it is not advisable to mix it with other types of pesticides or fungicides, as mixing hunger can affect its bactericidal effect and will have an adverse effect on the plant. In addition, different pesticides and fungicides have different ingredients, and mixing them will produce chemical reactions, resulting in the result of not having the best number of front limbs.

If multiple diseases need to be controlled at the same time, it is recommended to use a special multi-effect fungicide, or spray with different pesticides or fungicides separately to avoid unnecessary risks. Hope it helps! Have a great day
