Tata Marcellus Fungicide - Trifloxystrobin 25% + Hexaconazole 25% WG

Tata Marcellus Trifloxystrobin 25% + Hexaconazole 25% WG Fungicide

Tata Marcellus is a combination fungicide containing Trifloxystrobin 25% + Hexaconazole 25% w/w WG. It combines strobilurin and triazole fungicide chemistry to support preventive and curative management of fungal diseases approved on the current product label.

Trifloxystrobin disrupts energy production in susceptible fungi and helps prevent spore germination. Hexaconazole is a systemic fungicide that interferes with ergosterol biosynthesis, affecting the formation and functioning of fungal cell membranes.

This complementary action helps protect existing plant tissue and control developing infections when Marcellus is applied at the correct crop stage, disease stage and label-recommended dosage.

Technical Composition

Active Ingredient	Concentration	Chemical Group
Trifloxystrobin	25% w/w	Strobilurin / QoI fungicide
Hexaconazole	25% w/w	Triazole / DMI fungicide
Formulation	Water-Dispersible Granules (WG)

Dual Mode of Action

Active Ingredient	Mode of Action	Functional Role
Trifloxystrobin	Inhibits mitochondrial respiration at the Qo site	Helps prevent spore germination and early fungal development
Hexaconazole	Inhibits sterol biosynthesis in fungal cells	Provides systemic activity against developing infections

Technical correction: Hexaconazole does not directly inhibit construction of a conventional fungal “cell wall.” It inhibits ergosterol biosynthesis, thereby disrupting fungal cell-membrane development and function.

Key Features

• Two Active Ingredients: Combines strobilurin and triazole fungicide chemistry.
• Preventive Activity: Helps protect healthy plant surfaces against the establishment of susceptible fungal pathogens.
• Curative Activity: Hexaconazole provides systemic support against developing infections when applied at the appropriate stage.
• Locally Redistributive Action: Trifloxystrobin can redistribute over treated plant surfaces and contribute to coverage.
• WG Formulation: Water-dispersible granules are designed to form a uniform spray suspension when mixed correctly.
• Crop-Health Support: Effective disease management helps preserve green leaf area and photosynthetic potential.

Potential Benefits

• Supports preventive and curative fungal-disease management.
• Helps prevent germination of susceptible fungal spores.
• Helps control developing fungal infections within treated tissues.
• Supports protection of healthy leaves and crop canopy.
• Helps preserve photosynthetically active green foliage.
• Supports crop quality and yield potential by reducing disease damage.
• Provides two modes of action in a single formulation.

Dosage and Application

The supplied content suggests a general dose of 1 g per litre of water or approximately 200 g per acre. However, this dosage has not been verified from the current registered Marcellus label.

Application Parameter	Recommendation
Exact Dose	Follow the crop- and disease-specific quantity on the current label
Water Volume	Use the crop-specific spray volume printed on the label
Application Method	Foliar spray using properly calibrated equipment
Application Timing	Apply preventively or at an early disease stage where label-approved
Repeat Interval	Repeat only at the interval stated on the current label
Waiting Period	Observe the crop-specific pre-harvest interval

General Spray-Preparation Procedure

1. Identify the disease correctly before selecting the fungicide.
2. Confirm that the crop and disease are approved on the current label.
3. Measure only the label-recommended quantity of Marcellus.
4. Prepare a slurry or pre-solution using a small quantity of clean water.
5. Half-fill the spray tank with clean water.
6. Add the prepared slurry while maintaining continuous agitation.
7. Add the remaining label-recommended water volume.
8. Spray uniformly over the crop canopy without excessive runoff.
9. Maintain agitation during application.
10. Use the spray mixture promptly and clean the equipment afterward.

Best Application Practices

• Apply preventively or at the earliest visible disease symptoms.
• Ensure uniform coverage of the upper and lower crop canopy.
• Avoid spraying during strong wind or extreme heat.
• Do not spray immediately before expected rainfall.
• Do not apply to severely wilted or otherwise stressed crops.
• Use clean water and properly calibrated spraying equipment.
• Do not exceed the recommended dose, frequency or number of applications.

Rainfastness Guidance

The supplied description claims approximately two-hour rainfastness. Because this interval has not been verified from the current label, do not publish it as a guaranteed specification. Avoid spraying when rainfall is expected and follow the label-stated rain-free period.

Fungicide Resistance Management

Trifloxystrobin belongs to FRAC Group 11, while Hexaconazole belongs to FRAC Group 3. Resistance can still develop if this combination or related chemistries are repeatedly used.

• Do not exceed the label-approved number of applications.
• Rotate with effective fungicides from different FRAC groups.
• Avoid repeated use of Group 11 + Group 3 mixtures alone.
• Apply at the recommended dose and disease stage.
• Use resistant varieties where suitable and available.
• Remove infected crop residues according to local recommendations.
• Combine fungicides with suitable cultural disease-management practices.

Tank-Mix Compatibility

Do not assume universal compatibility with insecticides, fertilizers or plant growth regulators. Prepare a tank mixture only when every relevant label permits the combination.

Conduct a small jar test before preparing an unfamiliar mixture. Do not use a combination that develops sediment, separation, lumps, excessive heat or another sign of incompatibility. A jar test does not by itself confirm crop safety or chemical compatibility.

Safety Precautions

• Read the complete product label and accompanying leaflet before use.
• Wear gloves, protective clothing, eye protection and a suitable mask.
• Avoid inhaling granule dust or spray mist.
• Avoid contact with skin and eyes.
• Do not eat, drink or smoke during mixing and application.
• Spray in the direction of the wind.
• Wash hands, exposed skin and contaminated clothing after use.
