Product introdution

Triadimenol is a broad-spectrum, systemic triazole fungicide widely used for seed treatment and foliar disease management in cereals and other crops.It combines excellent preventive and curative activity, long-lasting protection, and growth-promoting effects, making it a core fungicide in integrated crop protection programs. Proper dosage and resistance management are essential for sustainable use.

Basic Information

Common Name: Triadimenol

CAS No.:55219-65-3

Molecular Formula: C₁₄H₁₈ClN₃O₂

Chemical Category: Triazole fungicide (Sterol Biosynthesis Inhibitor, SBI)

 Mode of Action

Triadimenol is a systemic triazole fungicide that inhibits the biosynthesis of ergosterol, a key component of fungal cell membranes.

Target Site: Inhibits C-14 demethylase enzyme involved in sterol biosynthesis.

Mode of Action: Disrupts the formation of normal fungal cell membranes, increasing permeability and leading to leakage of cellular contents.

Result: Inhibits fungal growth, causes deformation, and eventually leads to cell death.

Systemic Property: Rapidly absorbed and translocated within plants, providing both protective and curative activity.

Product Features

High systemic activity: Effectively controls infections both preventively and curatively by killing pathogens inside the plant.

Long residual control: Provides extended protection due to strong systemic persistence.

Flexible application: Suitable for seed treatment and foliar spraying.

Growth-promoting effect: At recommended rates, it can enhance root growth, shorten plant height, and improve crop vigor.

Application Crops

Commonly used on a variety of field and economic crops:

Cereal crops: Wheat, barley, oats, maize, and sorghum.

Vegetables: Cucumber, melon, and other cucurbits.

Others: Peanut, ornamental flowers, and turf.

Product Precautions

Phytotoxicity risk: Excessive concentration may inhibit germination or cause growth retardation in sensitive varieties.

Resistance management: Rotate with fungicides having different modes of action to delay resistance development.

Safety interval: Observe the prescribed pre-harvest interval (PHI) for each crop.

Personal protection: Wear protective clothing and gloves during handling, seed dressing, or spraying.
