Pyraclostrobin 250 g/L EC

ICAMA Reg. No. PD20172035

Product Category:  Fungicides 

A broad-spectrum fungicide offering protective and curative action against various fungal diseases across multiple crops, enhancing plant health and yield.

Why Choose Pyraclostrobin 250 g/L EC?

• Inhibits mitochondrial respiration in fungi, leading to effective disease control.

• Provides translaminar activity, protecting both treated and untreated leaf surfaces.

• Demonstrates efficacy against a wide range of fungal pathogens.

Key Features:

1.      Mode of Action: Pyraclostrobin disrupts electron transport in the mitochondrial respiratory chain of fungi, halting energy production and leading to fungal cell death.

2.      Translaminar and Systemic Activity: Upon application, pyraclostrobin exhibits translaminar movement, allowing it to penetrate leaf tissues and protect both upper and lower surfaces.

3.      Broad-Spectrum Efficacy: Effective against a variety of fungal diseases, including anthracnose (Colletotrichum musae) in bananas, black spot (Guignardia citricarpa) in citrus, and downy mildew (Plasmopara viticola) in grapes.

4.      Enhanced Plant Health: Beyond disease control, pyraclostrobin has been observed to promote physiological benefits in plants, such as improved stress tolerance and enhanced growth, leading to better yields.

Detailed Description:

Pyraclostrobin 250 g/L EC is an emulsifiable concentrate fungicide designed to manage a wide array of fungal diseases in various crops. As a member of the strobilurin family, it operates by inhibiting the cytochrome bc1 complex in the mitochondrial respiratory chain of fungal cells. This inhibition disrupts ATP synthesis, depriving the fungus of essential energy required for growth and reproduction, ultimately leading to its demise. The compound's translaminar activity ensures that, once applied, it moves through the leaf tissue, providing protection on both sides of the leaf. This characteristic is particularly advantageous in controlling pathogens that colonize the undersides of leaves or within the leaf tissue itself. Pyraclostrobin's broad-spectrum efficacy encompasses diseases such as anthracnose in bananas, black spot in citrus, and downy mildew in grapes. Additionally, research has indicated that pyraclostrobin may confer physiological benefits to plants, including enhanced stress tolerance and improved growth parameters, which can contribute to increased crop yields. Its versatility and dual protective-curative action make it a valuable tool in integrated disease management programs.

Effective Against:

·         Bananas:

• Anthracnose (Colletotrichum musae): Manifests as black lesions on fruit, leading to post-harvest losses.

·         Citrus:

• Black Spot (Guignardia citricarpa): Causes dark, sunken lesions on fruit, affecting marketability.

·         Grapes:

• Downy Mildew (Plasmopara viticola): Results in yellowish oil spots on leaves, leading to defoliation and reduced yield.

·         Tomatoes:

• Early Blight (Alternaria solani): Characterized by concentric ring lesions on leaves and stems, leading to defoliation and fruit drop.

·         Potatoes:

• Late Blight (Phytophthora infestans): Presents as water-soaked lesions on leaves and tubers, causing significant yield losses.

Registered Scope and Method of Use

* Note: Harvest bananas at approximately 80% maturity. On the day of harvest, dip the fruit in the prepared solution for 2 minutes, then allow to air dry. Limit to one application per season to prevent potential resistance development.

Technical Application Requirements:

1.      Timing & Frequency: For post-harvest diseases like anthracnose in bananas, treat immediately after harvest to prevent infection during storage and transit. Adhere to the recommended application frequency to minimize resistance risk.

2.      Application Technique: Ensure the dipping solution is well-mixed and maintained at the appropriate concentration. Fully submerge the fruit to guarantee complete coverage.

3.      Environmental Considerations: Pyraclostrobin is highly toxic to aquatic organisms. Prevent contamination of water bodies during preparation and application. Dispose of any residual solution responsibly, following local environmental regulations.

4.      Resistance Management: As a QoI fungicide (FRAC Group 11), pyraclostrobin should be used in rotation with fungicides possessing different modes of action. Avoid consecutive applications to reduce the risk of resistance development. Implement integrated disease management practices, including cultural and biological controls, to enhance efficacy and sustainability.
