Pyraclostrobin 5% + Metiram 55% WDG

ICAMA Reg. No. PD20180566

Product Category: Fungicides 

A broad-spectrum, systemic fungicide formulation designed to prevent and control a wide range of fungal diseases in various crops.

Why Choose?

• Offers dual modes of action, enhancing efficacy against resistant strains.

• Provides both preventive and curative control of fungal pathogens.

• Suitable for use on multiple crops, increasing versatility in disease management.

Key Features:

1.      Dual Modes of Action: Pyraclostrobin inhibits mitochondrial respiration in fungi, disrupting energy production, while metiram acts as a multi-site inhibitor, interfering with several enzymatic processes within the fungal cells.

2.      Preventive and Curative Properties: The combination ensures that the fungicide not only prevents spore germination and initial infection but also halts the progression of early-stage infections.

3.      Broad-Spectrum Efficacy: Effective against a variety of fungal pathogens, including those causing scab, blight, and mildew across different crops.

4.      Resistance Management: The multi-site action of metiram reduces the risk of resistance development, making it a valuable tool in integrated pest management programs.

Detailed Description:

Pyraclostrobin 5% + Metiram 55% WDG is a water-dispersible granule formulation that combines two fungicidal agents with complementary modes of action. Pyraclostrobin, a strobilurin-class fungicide, inhibits the cytochrome bc1 complex in the mitochondrial electron transport chain of fungi, effectively blocking ATP synthesis and leading to cellular energy depletion. This action disrupts critical processes such as spore germination and mycelial growth. Metiram, a dithiocarbamate fungicide, acts on multiple sites within the fungal cell by interfering with enzyme activity through the formation of disulfide bonds, thereby hindering lipid metabolism and respiration. The combination of these two active ingredients provides a robust defense against a wide array of fungal pathogens, offering both protective and curative benefits. The formulation is designed for ease of application and ensures uniform distribution on plant surfaces, leading to enhanced disease control and improved crop yields.

Effective Against:

·         Citrus Trees:

• Scab (Elsinoë fawcettii): Causes raised, corky lesions on       fruit, leaves, and twigs, leading to reduced marketability and vigor.

·         Potatoes:

• Early       Blight (Alternaria solani): Manifests as concentric leaf       spots, leading to defoliation and tuber yield loss.

• Late       Blight (Phytophthora infestans): Characterized by water-soaked       lesions on leaves and stems, rapidly leading to plant collapse.

·         Tomatoes:

• Early       Blight (Alternaria solani): Results in target-like spots on       leaves and fruit, causing premature leaf drop and reduced fruit quality.

·         Grapes:

• Downy       Mildew (Plasmopara viticola): Presents as yellowish oil spots       on leaves, leading to necrosis and potential crop loss.

Registered Scope and Method of Use

*Note: Apply preventively or at the early onset of disease symptoms. Repeat applications at 10–14 day intervals as necessary. Do not apply if rain is expected within 1 hour or during windy conditions to prevent drift and ensure optimal coverage.

Technical Application Requirements:

1.      Timing & Frequency: Initiate applications before disease onset or at the first sign of symptoms. Depending on disease pressure, repeat treatments every 10–14 days. Do not exceed three applications per season, adhering to a pre-harvest interval of 21 days.

2.      Application Technique: Utilize ground-based sprayers calibrated to deliver uniform coverage. Ensure thorough wetting of foliage, including the undersides of leaves, for effective protection.

3.      Environmental Conditions: Optimal application conditions include calm weather to minimize drift and temperatures between 15°C and 25°C. Avoid applications during periods of high rainfall or when rain is anticipated shortly after spraying.

4.      Resistance Management: To prevent the development of resistant fungal strains, rotate with fungicides possessing different modes of action. Integrate cultural practices such as crop rotation, field sanitation, and the use of resistant cultivars to enhance disease control efficacy.
