More Details

In modern agriculture, managing fungal diseases is critical to ensuring healthy crop growth and high yields. Topmast, a premium-quality fungicide formulated with Thiophanate Methyl 70% WP, offers robust and long-lasting protection against a wide range of fungal infections in crops. Designed for curative, protective, and systemic action, Topmast is the farmer's reliable solution to safeguard their investment and productivity.


🔬 Composition:

  • Active Ingredient: Thiophanate Methyl – 70%

  • Formulation: Wettable Powder (WP)

  • Chemical Group: Benzimidazole


🛡️ Mode of Action:

Topmast works by systemic movement within the plant and inhibition of fungal cell division. Once applied, the active ingredient is absorbed through foliage or roots and transported throughout the plant's vascular system. Thiophanate Methyl interferes with fungal mitosis by binding to β-tubulin, which prevents spore germination and fungal multiplication.

It acts both preventively—by shielding healthy tissues—and curatively—by eliminating early-stage infections, providing comprehensive disease management even after exposure.


🌾 Crops Protected:

Topmast is suitable for a wide range of agricultural, horticultural, and plantation crops. It is widely used in:

  • Vegetables: Tomato, chilli, brinjal, cucumber, cabbage, cauliflower, okra

  • Fruits: Grapes, banana, mango, apple, pomegranate, citrus

  • Field crops: Groundnut, cotton, wheat, paddy, soybean

  • Ornamentals and floriculture: Rose, marigold, chrysanthemum, gerbera


🦠 Target Diseases:

Topmast is highly effective against several devastating fungal diseases, including:

  • Leaf Spot (Cercospora, Alternaria)

  • Anthracnose

  • Powdery Mildew

  • Scab

  • Blight (Early and Late)

  • Fusarium Wilt

  • Damping-off

  • Collar Rot

  • Stem Rot

  • Rust

  • Die-back

  • Fruit Rots

  • Downy Mildew (as a part of a mix or program)


Key Benefits of Topmast:

1. Broad-Spectrum Protection

Topmast offers effective control over a variety of fungal pathogens, covering both foliar and soil-borne diseases in multiple crops.

2. Systemic Movement

The fungicide is absorbed by the plant and translocated upward, offering internal protection and ensuring new growth remains disease-free.

3. Preventive & Curative Action

It not only shields healthy plants from infection but also controls early-stage fungal infestations, preventing the spread within crop fields.

4. Improves Plant Health

By reducing fungal load, Topmast allows plants to channel their energy toward growth and fruiting, enhancing overall crop vigor and yield.

5. Long Residual Effect

Its long-lasting action reduces the need for frequent applications, saving costs on labor and spray cycles.

6. Compatible in Tank Mixes

Topmast is generally compatible with most insecticides and fungicides, allowing farmers to adopt it easily into their spraying schedules.

7. Environmentally Tolerant

Effective even under fluctuating environmental conditions such as humidity and temperature extremes.
