ICAMA Reg. No. PD20090023

Product Category:   Fungicides 

A broad-spectrum protective fungicide preventing various fungal diseases across multiple crops, including cucumbers, tomatoes, potatoes, grapes, and peanuts.

Key Features:

1.      Broad-Spectrum Control: Effective against a wide range of fungal pathogens affecting diverse crops.

2.      Protective Action: Forms a protective barrier on plant surfaces, inhibiting fungal spore germination and penetration.

3.      Multi-Site Activity: Targets multiple sites within fungal cells, reducing the risk of resistance development.

Detailed Description:

This 75% Wettable Powder formulation of chlorothalonil offers robust protection against numerous fungal diseases. Chlorothalonil is a non-systemic, broad-spectrum fungicide that acts as a protective barrier on plant surfaces. Its mode of action involves inhibiting multiple enzymatic processes within fungal cells, particularly by binding to thiol groups in enzymes, disrupting metabolic functions, and leading to cell death. The multi-site activity of chlorothalonil makes it a valuable tool in integrated disease management programs, as it lowers the potential for fungi to develop resistance.

Effective Against:

·         Cucumber Downy Mildew (Pseudoperonospora cubensis): Causes yellowing and angular lesions on leaves, leading to reduced yield.

·         Tomato Early Blight (Alternaria solani): Results in dark spots on leaves and stems, affecting fruit quality and yield.

·         Potato Late Blight (Phytophthora infestans): Leads to dark lesions on leaves and tubers, causing significant crop losses.

·         Grape Downy Mildew (Plasmopara viticola): Manifests as yellowish oil spots on leaves, leading to defoliation and reduced fruit quality.

·         Peanut Leaf Spot (Cercospora arachidicola): Causes brown spots on leaves, leading to premature defoliation and yield reduction.

Registered Scope and Method of Use

Technical Application Requirements:

1.      Timing: Initiate applications at the early onset of disease symptoms or when conditions favor disease development.

2.      Mixing: Prepare the spray solution by accurately measuring and mixing the recommended amount of fungicide with water, ensuring thorough agitation for uniform distribution.

3.      Application Technique: Ensure even coverage of all plant parts, including the undersides of leaves, where pathogens often reside.

4.      Environmental Conditions: Avoid application during windy conditions or if rainfall is expected within 2 hours to prevent runoff and ensure maximum efficacy.

5.      Safety Measures: Wear appropriate personal protective equipment during mixing and application. Avoid inhalation and contact with skin or eyes. Do not eat, drink, or smoke during application. Wash hands and exposed skin thoroughly after handling.

6.      Resistance Management: To prevent the development of resistance, alternate with fungicides having different modes of action and avoid repeated applications of the same product.
