Difenoconazole is a triazole fungicide. It interferes with the demethylation process in fungal cells. This inhibition prevents the biosynthesis of ergosterol, a key component of cell membranes. As a result, it disrupts the structure and function of the cell membrane. This disruption leads to halted growth or even death of the fungi. Difenoconazole provides three main actions: systemic, therapeutic, and protective. It acts quickly. After spraying, crops absorb it within a short time and transport it upward. This effectively controls the occurrence and spread of diseases.
Propiconazole is a triazole fungicide. Its mechanism of action is similar to other triazoles. It acts as a sterol demethylation inhibitor. When it contacts pathogens, it disrupts the biosynthesis of ergosterol. This process damages the structure and function of cell membranes. As a result, it halts fungal growth and can lead to death. Propiconazole provides protective, therapeutic, and eradicative effects. Propiconazole is absorbed by the roots, stems, and leaves of crops. It quickly translocates within the plant. Its distribution and translocation are unique. It has strong upward systemic movement and distinctive gas-phase distribution. This helps protect new tissues and organs in crops. It enhances the prevention of diseases effectively.
Application of Difenoconazole
1. Application on Fruit Trees:
Difenoconazole controls banana leaf spot disease and black star disease. It also combats black star disease and ring spot disease in apples and pears, as well as apple scab disease. Additionally, it is effective against anthracnose in citrus, lychee, and grapes, and it controls citrus canker disease. It also addresses black rot and white rot in grapes, and it helps prevent pomegranate scab disease.
2. Application on Cereal Crops:
Difenoconazole protects against rice sheath blight and rice blast disease. It also controls large and small leaf spot diseases in corn, early blight in potatoes, and black loose smut, including loose smut, greasy loose smut, and dwarf greasy loose smut in wheat. Furthermore, it combats root rot, sheath blight, head blight, and powdery mildew in wheat.
3. Application on Vegetables, Economic Crops, and Other Crops:
Difenoconazole controls vine decline and anthracnose in watermelons. It also addresses powdery mildew, ring spot disease, leaf spot disease, black spot disease, anthracnose, brown spot disease, and gray mold in strawberries. It combats anthracnose in peppers, as well as leaf mold, leaf spot disease, powdery mildew, and early blight in tomatoes. It helps control brown spot disease, leaf spot disease, and powdery mildew in eggplants. Additionally, it addresses powdery mildew, anthracnose, and vine decline in cucumbers and other melons. It controls leaf spot disease, rust, anthracnose, and powdery mildew in beans and cowpeas. It also combats black spot disease in cruciferous vegetables like cabbage. Lastly, it protects garlic and onions from early blight, rust, purple blotch, and black spot disease, as well as controlling leaf blight in garlic. It also addresses stem blight in asparagus and black spot disease in ginseng, and it combats anthracnose in tea plants.
Features of Propiconazole
1. Propiconazole has high fungicidal activity and is effective against diseases caused by higher fungi on various crops. It can control powdery mildew, anthracnose, rust, and root rot, and is particularly effective against watermelon vine wilt and strawberry powdery mildew. However, it is ineffective against downy mildew and late blight.
2. Propiconazole has strong systemic properties and bidirectional translocation. It can kill invading pathogens within 2 hours of application, controlling disease spread in 1-2 days and preventing outbreaks. Its penetration and adhesion are extremely strong, making it especially suitable for use during rainy seasons.
3. Its residual effect lasts for 15-35 days, saving 2-3 applications compared to conventional products.
4. Its unique "vapor-phase activity" ensures that even with uneven spraying, the solution distributes evenly within the leaf tissues of the crops, achieving ideal control effects.
5. After harvest, it has significant preservation effects, resulting in attractive appearance and extended marketability of the fruits.
Application of Propiconazole
1. Vegetable Diseases
Control powdery mildew on strawberries, tomatoes, onions, lettuce, coriander, bitter melon, and others. For rust on leeks, onions, chives, garlic, daylilies, lentils, broad beans, cowpeas, and water bamboo, use 25% propiconazole emulsion at 3000 times dilution for 2-3 applications at the early stages.
For anthracnose on tomatoes and leaf spot on peppers, use 25% propiconazole emulsion at 2500 times dilution at the early stages.
For early blight on tomatoes, use 25% propiconazole emulsion at 2000-3000 times dilution at the early stages.
For brown spot and leaf blight on peppers, apply immediately when symptoms appear, using 25% propiconazole emulsion at 40 mL per acre mixed with 45-60 kg of water. Reapply after 15-20 days.
For stem base rot on eggplants, use 25% propiconazole emulsion at 2500 times dilution for root drenching, applying 250 mL per plant for 2-3 applications.
For wilt on pumpkins, use 25% propiconazole emulsion at 1500 times dilution at the early stages.
For anthracnose, powdery mildew, and leaf spot on cucumbers, use 25% propiconazole emulsion at 4000 times dilution at the early stages.
For anthracnose on bitter melons and melons, use 25% propiconazole emulsion at 1000 times dilution at the early stages.
For vine wilt on watermelons during the swelling period, use 25% propiconazole emulsion at 5000 times dilution, or for root drenching, use 250 mL per plant at 2500 times dilution for 2-3 applications.
