Key Benefits of Topstar Fungicide

• Dual Fungicidal Action: Combines Azoxystrobin and Difenoconazole to target different processes involved in fungal growth.
• Broad-Spectrum Disease Management: Helps manage several important fungal diseases in manufacturer-recommended crops.
• Preventive Activity: Azoxystrobin helps inhibit spore germination and early development of susceptible fungi.
• Early Curative Activity: Difenoconazole helps suppress susceptible fungal infections during their early development.
• Systemic and Translaminar Movement: The formulation's active ingredients can move within treated plant tissues, supporting disease management.
• Multiple Crop Applications: The manufacturer provides recommendations for cereals, vegetables, cotton, sugarcane and turmeric.

How Does Silver Sine Topstar Work?

Azoxystrobin (FRAC Group 11): Inhibits mitochondrial respiration at the Qo site of the cytochrome bc1 complex. This interferes with fungal energy production and helps prevent spore germination and infection development.

Difenoconazole (FRAC Group 3): Inhibits sterol 14-alpha-demethylase, an enzyme involved in ergosterol biosynthesis. This disrupts fungal cell membrane formation and restricts the growth of susceptible pathogens.

The combination offers two complementary fungicidal mechanisms. Disease suppression depends on pathogen susceptibility, application timing, spray coverage and environmental conditions.

Recommended Crops, Diseases and Dosage

Silver Sine lists the following crops and diseases for Topstar. The manufacturer's product page specifies a spraying concentration of 1 ml per litre of water for each listed crop.

Dosage Source: The above recommendations are published on Silver Sine's Topstar product page. Follow the current registered product label to confirm approved crop uses, disease claims and spray instructions. The table represents manufacturer-listed uses and does not independently establish registration for every crop.

Application Guidance

For foliar application, the manufacturer lists 1 ml of Topstar per litre of water. Measure the required quantity, mix thoroughly with clean water and apply using a suitable agricultural sprayer.

Ensure uniform coverage of disease-prone plant surfaces. Use the crop-specific total spray volume, application interval and timing stated on the original product label.

Avoid spraying during strong winds or rainfall. Follow instructions concerning re-entry, pre-harvest waiting periods and compatibility with other agricultural inputs.

When Should You Use Topstar?

Topstar is intended for preventive or early-stage management of susceptible fungal diseases in recommended crops. Regular crop monitoring helps identify the first signs of infection and determine suitable application timing.

Existing severely damaged plant tissues cannot be restored by fungicide application. Avoid unnecessary repeated use of fungicides from the same FRAC groups, particularly Group 11, to reduce the risk of resistance.
