Crop diseases and insect pests are the main factors limiting high yield and quality. Chemical pesticide control is the fastest and most effective way to control diseases. Choosing excellent fungicides is the prerequisite for controlling diseases. Today I recommend an excellent fungicide formula that can prevent and treat dozens of diseases, supplement trace elements, improve crop photosynthesis, and improve plant disease resistance.
1. Formula introduction
This fungicide formula is azomethine·mantiazole, which is a composite fungicide made of 55% mantiazole and 5% pyraclostrobin. Mantiazole is a protective broad-spectrum fungicide developed on the basis of mancozeb with good safety, high zinc content (18% zinc), and long lasting effect. It overcomes the disadvantage of mancozeb that it is easy to cause phytotoxicity, increases the content of zinc ions, and has a good protective effect on dozens of diseases such as pear black spot, apple leaf spot, vegetable blight, downy mildew, and field crop rust.
At the same time, it can also supplement a large amount of zinc, increase the photosynthesis rate of leaves, make the leaves more dense and green, and have stronger disease resistance; pyraclostrobin is the most excellent broad-spectrum methoxyacrylate fungicide developed at the beginning of this century. It is a mitochondrial respiration inhibitor with strong permeability and systemic conductivity. It has the effects of preventing, protecting, treating and eradicating dozens of diseases caused by various pathogens such as flagellates, imperfect fungi, basidiomycetes, and ascomycetes. At the same time, it can also stimulate growth, increase yield and improve quality.
2. Main features
(1) Broad fungicide spectrum: This formula can effectively prevent and control dozens of diseases caused by various pathogens such as imperfect fungi, flagellates, basidiomycetes, and ascomycetes, such as downy mildew, anthracnose, vine blight, blight, early blight, late blight, powdery mildew, fusarium head blight, rust, leaf spot, brown spot, target spot, etc. (2) Thorough treatment: This formula has strong permeability and good systemic absorption. After spraying, it can be quickly absorbed by the stems and leaves and transmitted to all parts of the crop. It has protective, preventive, therapeutic and eradication effects on a variety of diseases.
(3) Long lasting effect: This formula can be absorbed by the roots, stems and leaves of crops and remain in the crop body for a long time. It is resistant to rain erosion and has a lasting effect of more than 15 days. If used for seed dressing, the lasting effect can be as long as more than 50 days.
(4) Good safety: This formula overcomes the disadvantage that pyraclostrobin is prone to causing phytotoxicity to certain crops. It is safer for crops and more reliable to use.
(5) Wide range of applications: This formula can be widely used in food crops such as wheat, rice, and corn, oil crops such as soybeans, peanuts, and rapeseed, vegetable crops such as cucumbers, tomatoes, and peppers, fruit trees such as apples, pears, peaches, and mangoes, as well as Chinese medicinal materials and flowers.
(6) Regulating growth: Methotrexate is rich in essential plant nutrients (zinc), which can promote chlorophyll synthesis, improve leaf vitality, and enhance crop photosynthesis. Pyraclostrobin can promote crop nitrogen absorption, enhance crop resistance, and help improve crop quality and yield. Increase the rate of leaf photosynthesis and enhance plant stress resistance.
3. Targets of control
It can control dozens of fungal diseases such as powdery mildew, black spot, leaf spot, brown spot, downy mildew, blight, anthracnose, vine blight, sooty mold, leaf spot, ring rot, snowflake disease, black skin disease, fusarium head blight, brown spot, early blight, late blight, blight, downy mildew, etc.
4. Usage
(1) To prevent and control cucumber downy mildew, blight, vine blight, anthracnose and other diseases, use the drug before or at the early stage of the disease. Use 40-60g of 60% chlorfenapyr·mancozeb water dispersible granules per mu, add 30-40kg of water and spray evenly. Spray once every 7-14 days. Apply the drug up to 4 times per crop season, with a safe interval of 2 days.
(2) To prevent and control pepper blight, anthracnose, leaf spot, brown spot and other diseases, use the drug before or at the early stage of the disease. Use 40-100g of 60% chlorfenapyr·mancozeb water dispersible granules per mu, add 30-40kg of water and spray evenly. Spray the drug evenly on the whole crop, especially the base of the stem. Spray once every 7-10 days. Apply the drug up to 6 times per crop season, with a safe interval of 7 days.
(3) To prevent and control tomato late blight, early blight, and brown spot, apply the drug before or at the early stage of the disease. Use 40-60 grams of 60% chlorfenapyr·mancozeb water dispersible granules per mu, add 30-40 kilograms of water and spray evenly. Apply the drug continuously every 7 days. Apply the drug up to 2 times per crop per season, with a safe interval of 7 days.
(4) To prevent and control apple ring rot, leaf spot disease and other diseases, apply the drug before or at the early stage of the disease. Use 750-1000 times of 60% chlorfenapyr·mancozeb water dispersible granules. The first application should be carried out 7-10 days after the apple flowers have faded. Then apply the drug 4 times with an interval of 10-15 days, with a safe interval of 28 days.
(5) To prevent and control litchi downy mildew, apply medicine before or in the early stage of the disease, use 750-1000 times diluted 60% chlorfenapyr·mancozeb water dispersible granules, once at the inflorescence, late physiological fruit drop, small fruit stage, swelling stage and color change stage, and apply the medicine 4 times during the whole period, with a safe interval of 14 days.
