Crop diseases and pests are the main factors limiting high yield and quality. Chemical pesticide control is the quickest and most effective method for controlling diseases, and selecting excellent fungicides is a 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 enhance plant disease resistance.
1. Formula Introduction
The formula of this fungicide is Pyraclostrobin · Metiram, a composite fungicide composed of Metiram and Pyraclostrobin. Metiram is a safe, high zinc content (18% zinc), and long-lasting protective broad-spectrum fungicide developed on the basis of mancozeb. It overcomes the disadvantage of mancozeb's susceptibility to pesticide damage, increases the content of zinc ions, and has a good protective effect on dozens of diseases such as pear smut, apple leaf spot disease, melon and vegetable diseases, downy mildew, and field crop rust.
At the same time, it can also supplement a large amount of zinc element, improve the speed of leaf photosynthesis, make the leaves more dark green, and have stronger disease resistance; Pyroclostrobin is the most excellent methoxyacrylate broad-spectrum fungicide developed at the beginning of this century. It belongs to the category of mitochondrial respiratory inhibitors and has strong permeability and internal absorption conductivity. It has preventive, protective, therapeutic, and eradication effects on dozens of diseases caused by various pathogens such as flagellates, hemimonas, basidiomycetes, and ascomycetes. At the same time, it can also stimulate growth, increase yield, and improve quality.
2. Main features
(1) Broad spectrum of sterilization: This formula can effectively prevent and control dozens of diseases caused by various pathogens such as Pseudomonas aeruginosa, flagella, Basidiomycetes, Ascomycota, etc., including downy mildew, anthracnose, stem 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 internal absorption. After spraying, it can be quickly absorbed by stems and leaves, and transmitted to various parts of the crop. It has a protective, preventive, therapeutic, and eradication effect on various diseases.
(3) Long shelf life: This formula can be absorbed by crop roots, stems, and leaves, and can be stored in the crop for a long time. It is resistant to rainwater erosion and can last for more than 15 days. When used for seed mixing, the shelf life can reach more than 50 days.
(4) Good safety: This formula overcomes the disadvantage of pyracostrobin's susceptibility to pesticide damage on certain crops, making it safer for crops and more reassuring to use.
(5) Wide scope of application: this formula can be widely used in wheat, rice, corn and other grains, soybean, peanut, rape and other oil crops, cucumber, tomato, pepper and other vegetable crops, apple, pear, peach, mango and other fruit trees, as well as traditional Chinese medicine, flowers and so on.
(6) Regulating growth: Metiram 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. Improve the speed of leaf photosynthesis and enhance plant stress resistance.
3. Prevention and control targets
It can prevent and control dozens of fungal diseases, including powdery mildew, black spot disease, leaf spot disease, brown spot disease, downy mildew disease, epidemic disease, anthracnose disease, stem blight disease, coal smut disease, leaf spot disease, wheel rot disease, snowflake disease, black skin disease, scab, brown spot disease, early blight, late blight, epidemic disease, and downy mildew.
4. Usage
(1) To prevent and control cucumber downy mildew, blight, vine blight, anthracnose and other diseases, use 60% Pyraclostrobin · Metiram water dispersible granule 40~60g per mu, 30~40kg water, evenly spray every 7~14 days, with a maximum of 4 times per season, and a safety interval of 2 days.
(2) To prevent and control pepper blight, anthracnose, leaf spot, brown spot and other diseases, use 60% Pyraclostrobin · Metiram water dispersible granule 40~100g per mu and 30~40kg water spray evenly before or at the initial stage of the disease. Spray the liquid medicine evenly to the whole crop, especially the stem base, with an interval of 7~10 days. The crop can be applied 6 times per season at most, and the safe interval is 7 days.
(3) To prevent and control tomato late blight, early blight and brown spot disease, use 60% Pyraclostrobin · Metiram water dispersible granule 40~60g per mu, 30~40kg water, spray evenly, and apply the medicine continuously every 7 days. The crop can be applied twice a season at most, with a safe interval of 7 days.
(4) To prevent and control diseases such as apple ring rot and leaf spot disease, medication should be used before or in the early stages of the disease. 60% Pyraclostrobin · Metiram water dispersible granules should be used in a 750-1000 fold solution. The first application should be carried out 7-10 days after the apple withers, and four consecutive applications should be applied every 10-15 days, with a safe interval of 28 days.
(5) To prevent and control lychee downy mildew, medication should be used before or in the early stages of the disease. A 60% Pyraclostrobin · Metiram water dispersible granule solution should be used at a ratio of 750-1000 times. The medication should be applied once each during the flowering, late physiological fruit drop, small fruit stage, swelling, and color transformation stages. The medication should be applied four times throughout the entire period, with a safe interval of 14 days.
