Reading guide:Whether it is growing cash crops or vegetables, the most common diseases are powdery mildew, rust, wilt, etc. The cause of these diseases is nothing more than fungal and bacterial infections, and the core of solving them is sterilization. And today I still share a drug with a super fungicide "azole copper allicin emulsifiable concentrate", which should also be used by many vegetable farmers today. Whether it is effective for the roots, stems, leaves, etc. of crops, the characteristics of the product and the actual application will be shared.
What is copper allicin EC?To put it simply, it is a compound fungicide. Because it is composed of a mixture of ** ketone and allicin, but after the combination, the effect is better than that of using it alone. It also avoids some deficiencies in the single product, especially in the case of avoiding drug damage. The two kinds of single products are also briefly introduced, hoping to bring some pesticide science popularization and make a little effort.
Ketones
Ketone itself is a systemic low-toxicity fungicide belonging to the **class, and it is easily absorbed by crops. After the crop is absorbed, it will be conducted in the plant, so that the disease is eliminated for the whole plant. Especially for powdery mildew and rust control has a good effect, when using alone must pay attention to the concentration problem, once the concentration is high, it will produce pesticide damage, to a large extent inhibit the growth of crops.
Allicin
Allicin is also a fungicide, and its core is allicin. And this allicin is synthesized, this must be understood. Moreover, it is a fungicide with a broad spectrum, which belongs to the organic sulfur class, and its toxicity is neutral poison, which should be understood. The bactericidal principle of the preparation is to inhibit the metabolism of pathogens, so as to achieve the purpose of destroying germs. However, allicin also has the effect of stimulating the growth of crops, especially after the seeds are treated with allicin, the seedlings grow more robustly. There should be many old growers who have used the effect of allicin.
As a mixed agent, it achieves the effect of 1+1 greater than 2 in terms of efficacy. What is involved is that the systemic and permeability are stronger, which is more efficient for plants to absorb. Basically, in about half an hour, it can have a sterilizing effect. Whether it is a disease caused by fungi or bacteria, it has a very good control effect, which is the meaning of mixing.
Copper allicin EC has strong permeability and systemic conductivity, whether it is the roots, stems and leaves can be absorbed evenly and quickly, and the retention time in the plant body is also relatively long, basically about 18 days, which has a very good sterilization and protection time. After mixing, due to the problem of proportion, it also reduces the problem of drug damage of ** ketone and the situation that allicin is prone to leaf burning.
Copper allicin EC is suitable for most crops, such as: wheat, corn, soybeans, rice, tomatoes, peppers, cucumbers, watermelons, apples, peaches, pears, tea, oranges and so on. In addition, the diseases targeted, such as: powdery mildew, rust, wilt, smut, rice blast, gray mold, downy mildew, soft rot, blight, spot disease, etc. have good effects.
The use of copper allicin EC is spray, and you can pay attention to the humidity for greenhouse planting, and other planting modes are not a big problem. The core of the period is the problem of dilution concentration, and the effect is directly felt. There are certain differences in the concentration of different crops and disease dilution, and I will briefly cite some common crop diseases.
Wheat, rice, for example
Common diseases of wheat and rice crops are powdery mildew, rice blast and sheath blight. The use of copper allicin EC is generally better in the early stage of the disease, and the concentration of key dilutionTaking 32% copper allicin EC as an example, 60 kg of water needs to be mixed with 80 ml of copper azole allicin EC drug. The number of sprays is more diseased, and it can generally be solved at one time.
Tomato cultivation as an example
As far as tomato planting is concerned, the use of azole copper allicin emulsifiable concentrate is generally aimed at wilt, and the effect is still good. However, the time of medication is generally carried out in the early stage of the disease or the early stage of the disease, and the concentration of the drug dilutionTaking 32% copper allicin EC as an example, 60 kg of water needs to be mixed with 40 ml of copper azole allicin EC and sprayed 2-3 times, with an interval of 10-15 days. Basically, the continued development of the blight can be controlled.
Copper allicin EC cannot be mixed with alkaline pesticides, and iron containers cannot be used for preparation. In addition, it should be noted that the safety interval of the drug, generally rice planting for 21 days, a growth cycle can be used up to 2 times. The safe interval for cucumber planting is 5 days, and a maximum of 2 times can be used for one crop.
Summary:As a good fungicide, copper allicin EC is mainly characterized by overcoming the shortcomings of ketone and allicin, so as to avoid the occurrence of drug damage. And it has also played a good role in improving the efficacy, and planting netizens who have used this drug can also share their experience in the comment area. This can also be used to answer questions for people who encounter some diseases and confusion on the planting road, which is also good.
