Reading guide:Crop diseases are basically caused by fungi. Such as: powdery mildew, blight, blight, root rot, rust, etc., which are caused by fungi, in addition to some diseases caused by bacteria, such as: leaf blight, soft rot, bacterial wilt, horn spot, rhizobia, black rot and so on. With pyrimidine nucleoside antibiotics, it can be said that the spread can be controlled on the same day. Next, we will give a thorough introduction to the drug and share the actual application technology, hoping to bring some help to growers. List of high-quality authors
Pyrimidine nucleoside antibiotics, which are microbial broad-spectrum antibiotics. It was discovered by the Chinese Academy of Agricultural Sciences, and its commodity is also known as Nongkang 120. This drug is easily soluble in water, stable efficacy, low toxicity and low residue, and has very little pollution to the planting environment. It is very suitable for the sustainable development of today's agriculture, and continuous spraying also promotes the growth of crop branches and leaves, especially the leaves become green.
Why it works so well after spraying, this needs to start from its principle of action. First of all, it has a particularly strong systemic conductivity, after spraying on the crop, the drug will be absorbed by the crop very quickly, basically it can be said that it can be transmitted to the growth parts of the crop in tens of seconds. This is why it is said to have miraculous effects, and the simple understanding is that the drug works quickly. In addition, its principle of action in crops, pyrimidine nucleoside antibiotics can hinder the synthesis of pathogen proteins, so as to achieve disease control.
For crops, it can basically be said that most crops are OK, whether it is vegetables, fruits, melons and fruits. Cash crops such as wheat and rice, tomatoes, cucumbers, watermelons, apples, peaches, pears and other fruits and melons, as well as green leafy vegetables, cauliflower, rape, etc., can be applied. For diseases, the most common, powdery mildew, anthracnose, blight, black spot, blight, rust and so on are effective.
No matter what kind of pesticide, the use method is also a reason to determine the effect, simply speaking, the efficacy of the drug in addition to its own situation, that is the way to use. Its actual application method is roughly divided into three situations: spraying, root irrigation and smearing, and it must be clear that the three different methods target different crops.
Spray
Spray application method is the most common, it is mainly sprayed before the occurrence of crop diseases or in the early stage of disease occurrence, generally need to be sprayed 2-3 times, each time with an interval of about 10 days. Another important point is the concentration of spraying drugs, generally 6% water needs to be diluted 500-600 times, 2% water diluted 100-200 times, there are other types of specifications for reference instructions. For powdery mildew, black spot, gray mold, etc., the spraying effect is the best.
Root irrigation
In the case of root irrigation with pyrimidine nucleoside antibiotics, the main prevention and control of wilt and Verticillium wilt are carried out, and the root irrigation is carried out before or at the beginning of the disease, and the effect is the best. Generally, it is necessary to irrigate the roots 2-3 times, with an interval of about 10 days. The dilution concentration of the drug is the key, 2% water dilution 100-200 times, 6% water dilution 500-600 times, 8% powder dilution 600-800 times, etc., root irrigation agent generally needs a 200 ml dosage, the effect will be better.
Smear
Regarding the application of pyrimidine nucleoside antibiotics, it is mainly aimed at diseases on the trunk of fruit trees, and this effect is better. It is the appearance of diseases on the trunk of fruit trees, such as rot and disease spots. Use the drug to smear**, but there is a premise, use a knife to eliminate the disease before application, so that the drug can better penetrate into the fruit tree. In addition, there is a key problem of concentration, 2% water dilution 10 times, 4% water dilution 20 times, 8% granules dilution 40 times, etc., basically apply once.
No matter how good the pesticide is, it also has problems that need to be paid attention to, otherwise the effect will not be so ideal. It is important to keep in mind that it cannot be mixed with alkaline pesticides. In addition, the drug cannot be completely solved by using it once, and it generally needs to be sprayed 2-3 times continuously, with an interval of about a few months. The control of fungi, germs and bacteria can achieve a thorough effect, that is, the disease can be controlled.
Summary:Pyrimidine nucleoside antibiotics are also microbial pesticides, and they are also broad-spectrum antibiotic fungicides. It has a prevention and control effect on fungal diseases and bacterial diseases, but it must be remembered that one time cannot be completely solved, and it takes 2-3 times with an interval of about half a month for the best effect.
