What are the alkaline pesticides and what pesticides are alkaline pesticides

Pesticides are classified as alkaline, acidic, and neutral. Alkaline pesticides include aperium dipanil, stone sulfur mixture, poultan and intestinal lado liquid, lime sulfur mixture, dysen ammonium, lime, pine resin mixture, etc.; Acidic pesticides include dichlorvos, ergo, deltamethrin, etc.; Neutral pesticides include Kewensan and so on. These three pesticides with different properties should be stored separately during storage and storage, and the distance should be kept above meters, otherwise, the pesticides will affect each other and cause deterioration and failure.

1. What are the commonly used alkaline pesticides?

1.Boledo liquid: It is a sky blue suspension prepared with copper sulfate, quicklime and water, and is a protective agent.

2.Pine resin mixture (pine alkali mixture): It is a strong alkaline rosin soap made of rosin and caustic soda (sodium hydroxide) or alkaline noodles (sodium carbonate). It has a strong contact killing effect on pests and mite lamps.

3.Stone sulfur mixture (lime sulfur mixture): It is made by boiling lime and sulfur with water. Strong alkaline. It has the effect of killing acares and sterilizing.

4.Sodium pentachlorophenol: its aqueous solution is alkaline. It is a contact herbicide.

2. What are the pesticides that are easy to decompose when exposed to alkali?

1.Organophosphorus preparations: such as dichlorvos, trichlorfon, methamidophos, dimethoate, etc.

2.Organic nitrogen insecticides: Some organic nitrogen insecticides are unstable, such as: carbofuran, leafhopper, etc.

3.Pyrethroid insecticides: such as pyrethroid killing, pyrethroid killing, etc.

4.Acaricides: such as dicofol.

5.Fungicides: Some fungicides are unstable when exposed to alkali, such as: rice blast, Tobuzin, Dixon, etc.

Alkaline pesticides include propanny, luoami, Bordeaux liquid, sulfur suspension, stone sulfur mixture, etc.; Neutral pesticides include Kewensan and so on.

1. Stone sulfur mixture

It is a fungicide used in agriculture made by boiling quicklime, sulfur and water. Among the many fungicides, stone sulfur mixture is widely used by the majority of fruit farmers because of its advantages of convenient material extraction, low cost, good effect, and inhibition of a variety of pathogens.

Due to the many boiling links of stone sulfur mixture, the mother liquor boiled by fruit farmers is too low, and many people only dilute it with water with experience and spray it, so that it cannot achieve the expected control effect. Stone sulfur mixture is made by boiling quicklime, sulfur and water, and the best ratio of the three is 1:2:

10。When boiling, it is necessary to use a clay pot or a cast iron pot, and the use of copper or aluminum pot will affect the efficacy of the medicine.

2. Bordeaux liquid

Bordeaux liquor is an inorganic copper biocide, a sky blue gelatinous suspension formulated from about 500 grams of copper sulphate, 500 grams of hydrated lime and 50 kilograms of water. The ingredient ratio can be appropriately increased or decreased as needed. It is generally alkaline and has good adhesion properties, but it is suitable to be used for a long time or made of dehydrated Bordeaux powder, and then mixed with water when used.

Methods for the prevention of pesticide residues.

1. Soaking. You can soak the vegetables you bought for a few minutes before rinsing, and you can soak the vegetables with soda water, which can neutralize the pesticide toxicity. Do not use ordinary detergents to wash fruits and vegetables, the chemical components contained in the detergent itself are easy to remain on fruits and vegetables, which is not good for human health. The best way is to use a professional oxygen machine for cleaning, and the effective removal rate is 98%.

2. Peeling. Vegetables such as cucumbers and eggplants are generally used more pesticides, and these vegetables and fruits can be peeled directly before eating.

3. High temperature heating.

High-temperature heating can also decompose pesticides. Some heat-resistant vegetables, such as cauliflower, beans, celery, etc., can be washed and scalded with boiling water for a few minutes, which can reduce the amount of pesticides by 30%, and then cooked at high temperatures, 90% of pesticides can be removed.

4. Sunlight exposure.

Sunlight exposure can decompose and destroy some pesticides in vegetables. It has been determined that the residue of pesticides such as organochlorine and organic mercury can be reduced by about 60% when vegetables are exposed to sunlight for 5 minutes.

5. Soak in rice water.

In real life, rice washing water is a relatively common "good prescription" for removing pesticide residues. The rice washing water is weakly alkaline, which can neutralize the pesticide components and weaken the efficacy; The starch contained in rice washing water also has strong viscosity. Therefore, soaking and rinsing vegetables with rice washing water is simple and convenient, easy to implement, and has remarkable results.

Why do I talk specifically about the types of alkaline pesticides? Because at present, most of the pesticides in agricultural production are weakly acidic or neutral, and there are really not many types of alkaline pesticides, which can be carefully classified, so what are the specific types? Let's find out:

1) Most of the inorganic copper preparations are alkaline pesticides, such as copper hydroxide, royal copper, basic copper sulfate, etc., which are very common in our agricultural production. Organic copper preparations, such as thiazine copper, are not alkaline, but their safety is much better than that of inorganic copper preparations!

2) Bordeaux liquid, this agent is a real alkaline pesticide, the liquid contains Ca(OH)2 and other alkaline substances, in the fruit trees to white, clear the garden, growers often use, its most affordable, good effect!

3) Stone sulfur mixture, this pesticide is also commonly used, and the largest amount is used every winter when the fruit trees are cleared. I believe that many growers also know that it is alkaline, and this agent is generally used alone.

4) Pine resin mixture is also a common alkaline pesticide, and it is relatively alkaline. The pine resin mixture is made of a combination of pine resin and soda ash, which is extremely alkaline, including sodium pineinate, etc., which belong to alkaline agriculture.

At present, there are mainly these types of common alkaline pesticides on the market, and growers must pay attention to its alkaline properties when using them, and scientific mixing can improve the efficacy. So what problems should be paid attention to when using alkaline pesticides?

Precautions for alkaline pesticide mixing.

First of all, the first note, alkaline pesticides should not be mixed with strong acidic pesticides, they are very easy to react, resulting in poor effect, serious will also cause pesticide damage. Most alkaline pesticides can be mixed with weakly acidic pesticides!

Second, for inorganic copper preparations, such as copper hydroxide, etc., in addition to being unable to be mixed with alkaline pesticides, it cannot be mixed with pesticides containing metal ions, such as mancozeb, zebzeb and potassium dihydrogen phosphate, etc., which are prone to precipitation; In addition, inorganic copper preparations will also induce a high incidence of mites, so pay attention to it when using it in fruit tree areas!

Third, some pesticides are unstable when encountering alkaline agents and are prone to decomposition. For example, deltamethrin in pyrethroid agents, as well as dichlorvos and phosphine phosphine in organophosphate agents, it is best to consult local agricultural technicians when using!

Fourth, for pesticides prepared with inorganic copper, pay attention to the time when using, avoid the flowering and young fruit stages of crops, and do not use drugs at high temperatures, which are very prone to pesticide damage.

Fifth, for stone sulfur mixture and Bordeaux liquid, when using, it is generally recommended that growers use them alone, and it is not recommended that they use them together, so that the safety is the best.

Sixth, when copper pine acid is used, not only can it not be mixed with strong acids, but alkaline pesticides are not recommended to be mixed. However, copper pinein acid has a better effect than inorganic copper, does not induce mite harm, and is not easy to produce resistance.

When using alkaline pesticides, it is recommended to consult with pesticide sellers before mixing them, otherwise there is really a great risk of pesticide damage. Especially for the use of fruit trees and vegetables, it is recommended to have the guidance of grassroots agricultural technicians!

Summary. Alkaline pesticides mainly include Bordeaux liquid, stone sulfur mixture, sodium pentachlorophenol bactericidal herbicide, copper hydroxide, royal copper, basic copper sulfate, etc.

What pesticide is an alkaline pesticide?

Alkaline pesticides mainly include Bordeaux liquid, stone sulfur mixture, sodium pentachlorophenol fungicidal herbicide, copper hydroxide, copper king, basic copper sulfate, etc., which have strong alkaline effects. Amines, limes, vegetable ashes, Bordeaux liquids, and stone-sulfur mixtures are alkaline or strongly alkaline pesticides. It can be said that pesticides that can be mixed with stone sulfur mixtures can usually be mixed with Bordeaux liquids.

Is boron sulfide basic?

Weakly alkaline. Can sulfobar be added with avermectin?

Yes pro. Ok thanks.

Dear, if I'm still satisfied, please give a thumbs up!

The chemical fertilizer that belongs to the alkali is mainly Bordeaux liquid and stone sulfur mixture, especially the alkali of the stone sulfur mixture is strong, and in the chemical fertilizer, most of the genera that are more sensitive to the alkali, such as organic chemical amides. Carbamates. pyrethroids, etc.

1.Stone sulfur mixture, is made of quicklime powder. Sulfur powder is boiled with water, a kind of pesticide fungicide used in agriculture and animal husbandry.

Among many pesticide fungicides, stone sulfur mixture is convenient for sampling. High quality and low price. It works very well.

It has the advantages of inhibiting and killing various pathogenic bacteria, and is widely used by many growers.

However, because there are many boiling stages of stone sulfur mixture, the hydrolysate boiled by growers is too low, and at the same time, many people spray after mixing water dilution with work experience, so that it cannot achieve the estimated control effect.

Stone sulfur mixture, is made of quicklime powder. Sulfur powder is boiled with water, and the best ratio of the three is 1:2:10. When boiling, be sure to use a clay pot or pig iron pot, and the use of copper hot pot or aluminum pot will harm the medicinal effect.

2.Bordeaux liquor is an inorganic copper pesticide fungicide. 1882 French A

Mjalldai discovered its bacteriostatic effect in the city of Bordeaux, hence the name "Bordeaux liquid". It is made up of about 500 grams of sodium thiosulfate. 500 grams of lime and 50 kilograms of water diluted into a light blue gelatinous emulsion.

The seasoning ratio can be adjusted appropriately according to needs. Generally, it is alkaline and has excellent swelling characteristics, but the physical properties of long-term storage are destroyed, so it is suitable to be used or made into water-deficient Bordeaux powder. Mix with water when applying.

1.High efficacy.

The crystalline body of stone sulfur mixture is a new solid preparation made of liquid stone sulfur mixture basically through organic chemical production and processing, and its purity is high. The residue is less, and the efficacy is more than 2 times that of the traditional boiled stone sulfur mixture.

2.The effect is long-lasting.

The efficacy of the stone sulfur mixture crystal lasts for half a month, and the best efficacy is reached in 7-10 days.

3.Low residue.

After the product is dissolved, the relevant ingredients play the role of sterilization and acaricide, and the residual part is calcium. Sulfur and other factors of chemicals can be used in the fruit of green plants. Leaf digestion and absorption, it is necessary for the growth of plants.

4.No drug resistance.

Stone sulfur mixture has been used for more than 100 years, no drug resistance, it is a cheap broad-spectrum sterilization. Kill mites. Insecticides.
