Pyraclostrobin 20%+Tebuconazole 40% WDG

Product Description for Pyraclostrobin 20% + Tebuconazole 40% WDG

Pyraclostrobin 20% + Tebuconazole 40% WDG is a highly effective fungicide formulated as water-dispersible granules (WDG), combining two powerful active ingredients—Pyraclostrobin and Tebuconazole. This dual-action product offers preventive and curative control against a broad spectrum of fungal diseases, commonly applied to crops such as cereals, vegetables, fruits, and ornamentals.

Structural Formulas

• Pyraclostrobin: C19_{19}19​H18_{18}18​ClN3_{3}3​O4_{4}4​ - This compound belongs to the strobilurin class, targeting the fungal mitochondrial respiration process. Its unique structure blocks electron transport, inhibiting fungal growth and preventing spore germination.
• Tebuconazole: C16_{16}16​H22_{22}22​ClN3_{3}3​O - This compound is a triazole fungicide that disrupts the synthesis of ergosterol, an essential component of fungal cell membranes, leading to fungal cell death.

Combined Action and Benefits

The combination of Pyraclostrobin and Tebuconazole in a WDG formulation provides several advantages:

1. Broad-Spectrum Disease Control: Effective against diseases like powdery mildew, rust, leaf spots, early and late blight, anthracnose, and scab.
2. Dual Mode of Action: The dual mechanisms inhibit fungal respiration and cell membrane synthesis, enhancing the efficacy and reducing the risk of resistance.
3. Preventive and Curative Properties: Pyraclostrobin offers preventive protection by halting spore germination, while Tebuconazole’s curative action targets active infections, ensuring full-cycle disease management.
4. Improved Crop Health and Yield: This product not only controls diseases but also promotes a "greening effect," boosting photosynthesis and crop vigor.

Application Scope

• Crops: Recommended for use on cereals (wheat, barley), vegetables (tomatoes, cucumbers), fruits (apples, grapes), and ornamental plants.
• Diseases: Highly effective against powdery mildew, rust, leaf spots, blight, scab, and other fungal diseases affecting crop health and yield.

Additional Formulations and Concentrations

Pyraclostrobin and Tebuconazole are available in different formulations, such as SC (suspension concentrate) and EC (emulsifiable concentrate), and in various concentration combinations to meet different agricultural needs. For example, Pyraclostrobin 25% SC and Tebuconazole 43% SC can be used separately or combined to provide tailored solutions for specific crops or resistance management programs.
