Azoxystrobin is a fungicide that inhibits fungal growth by suppressing the elongation of downy mildew mycelium and cell division, achieving its bactericidal effect. Compared to traditional pesticides, mefenoxam is less likely to develop resistance and can maintain a high level of efficacy for a long time, effectively controlling downy mildew.
Difenoconazole is a low-toxicity heterocyclic fungicide. It has strong systemic activity and a broad spectrum of action. It rarely develops resistance. It is widely used in agriculture. Difenoconazole controls various diseases caused by ascomycetes, basidiomycetes, and deuteromycetes. It is particularly effective against diseases like leaf blight, black spot, and powdery mildew.
Its main mechanism involves disrupting C14 demethylation in pathogens. This inhibits ergosterol biosynthesis. It damages the physiological functions of cell membranes. Benzovindiflupyr strongly suppresses spore production in plant pathogens. Difenoconazole effectively controls disease progression and provides protective and therapeutic effects.
1. Broad spectrum of activity. Azoxystrobin is a broad-spectrum fungicide that can control nearly all fungal diseases caused by Ascomycetes, Basidiomycetes, Oomycetes, and Deuteromycetes, including early blight, late blight, downy mildew, gray mold, leaf mold, leaf spot, black star disease, black rot, damping-off, root rot, anthracnose, and wilt.
It is particularly effective against various diseases such as powdery mildew, rust, sheath blight, net blotch, stem rot, and rice blast, achieving multi-disease control with a single spray. It is suitable for a variety of cereal crops like wheat, corn, and rice, as well as cash crops such as peanuts, cotton, sesame, and tobacco, vegetable crops including tomatoes, watermelons, cucumbers, eggplants, and peppers, and numerous fruit trees such as apples, pears, kiwifruit, mangoes, lychees, longans, bananas, along with ornamental plants, lawns, and hundreds of other crops.
2. Strong penetration and systemic conduction. As mentioned previously, among Azoxystrobin, kresoxim-methyl, and pyraclostrobin, pyraclostrobin exhibits the strongest activity, while azoxystrobin demonstrates the highest permeability. When Azoxystrobin is sprayed on crop leaves, it causes the rearrangement of the cuticle and waxy layers as it penetrates the crop's epidermis, significantly enhancing the permeability of the surface, which is the reason behind Azoxystrobin's strong penetration. After penetrating the epidermis, it can be conducted to both the apex and basal parts, offering robust protection to the crops, including newly growing parts, while also providing some therapeutic effect on already infected areas, with a residual efficacy of up to 15 days.
3. Protection against plant aging and extended green leaf retention. Azoxystrobin increases the activity of peroxidase enzymes, which not only enhances the crop's disease resistance but also plays a role in delaying plant aging. It extends the retention of green leaves and prolongs the harvest period, thereby improving crop yield and quality.
1. Unique Mechanism of Action
Difenoconazole is a triazole fungicide. It disrupts the demethylation process in pathogenic cells. This inhibits the biosynthesis of ergosterol, a cell membrane component. It damages the structure and function of cell membranes. This leads to growth stagnation or death of the fungi, achieving fungicidal, preventive, and therapeutic effects.
2. Diverse Modes of Action
Difenoconazole has three modes of action: systemic, therapeutic, and protective. It acts quickly. After application, it is absorbed by crops in a short time and translocated upward. This effectively controls the occurrence and spread of diseases.
3. Broad Spectrum of Activity
Difenoconazole effectively controls various fungi. It targets diseases caused by ascomycetes, basidiomycetes, and deuteromycetes. It is suitable for vegetables, fruit trees, field crops, and flowers. It shows good efficacy against banana leaf spot, anthracnose, wheat sheath blight, and more.
4. Good Safety Profile
Triazole fungicides can cause phytotoxicity if misused. They may inhibit gibberellin synthesis, leading to slow apical growth and shortened internodes. Difenoconazole is one of the safest triazole fungicides and can be used safely during the seedling stage.
5. Good Compatibility
Difenoconazole can be mixed with various fungicides and insecticides, such as thia methoxam, imidacloprid, phoxim, pyraclostrobin, azoxystrobin, captan, dithianon, and other.
1. Main Uses
Difenoconazole, as a triazole fungicide, is relatively safe and can be widely applied to fruit trees, vegetables, cereal crops, rice, soybeans, and horticultural crops. It can be used for both seed treatment and spraying, making its applications very diverse.
2. Specific Usage
(1) Prevention of Early Blight in Potatoes: For each acre, use 50-80 grams of 10% Difenoconazole water-dispersible granules for spraying, with an effectiveness period of 7-14 days.
(2) Prevention of Pear Scab: At the initial stage of disease, spray with 6000-7000 times diluted solution of 10% Difenoconazole water-dispersible granules. If the disease is severe, the concentration can be increased.
(3) Prevention of Black Spot in Chinese Cabbage: Start spraying from the initial occurrence of the disease, approximately every 10 days, for about two applications. The dosage is 40-50 grams of 10% Difenoconazole water-dispersible granules.
(4) Prevention of Anthracnose in Grapes: Use a solution diluted 600-800 times from 10% Difenoconazole water-dispersible granules for whole plant spraying, applied every 7-10 days.
(5) Prevention of Large and Small Leaf Spot Diseases in Corn: For each acre, use 80 grams of 10% Difenoconazole water-dispersible granules mixed with 60-75 kilograms of water for spraying.
