Introduction
Trifloxystrobin丨CAS 141517-21-7 is a systemic, broad-spectrum fungicide belonging to the strobilurin class of agrochemicals. It is used extensively in agriculture to protect crops from fungal diseases by inhibiting mitochondrial respiration in fungal cells. Its CAS number is 141517-21-7, and it is characterized by preventive, curative, and residual activity. It is valued for its effectiveness at low application rates and its ability to control a wide range of fungal pathogens.
Applications
A. Agricultural Fungicide
Trifloxystrobin is primarily used for disease control in crops including:
Cereals (wheat, barley, rice)
Fruits (grapes, apples, citrus, bananas)
Vegetables (tomatoes, cucurbits, onions)
Ornamentals and turfgrass
It is effective against a wide spectrum of fungal pathogens, such as:
Powdery mildew (Erysiphales)
Rusts (Pucciniales)
Downy mildew (Peronosporales)
Leaf spots (e.g., Septoria, Alternaria)
Anthracnose and scab diseases
B. Turf Management
Trifloxystrobin丨CAS 141517-21-7 is used in golf courses, lawns, and sports fields for control of turfgrass diseases such as:
Dollar spot
Brown patch
Anthracnose
Snow mold
Its systemic and residual properties ensure extended protection with fewer applications.
C. Seed Treatment
Sometimes used as a seed treatment fungicide, offering early-stage disease protection during seed germination and seedling establishment.
Effective against seed-borne and soil-borne pathogens.
Benefits
A. Broad-Spectrum Efficacy
Controls a wide range of fungal diseases affecting multiple crop types.
Particularly effective against obligate biotrophic fungi, which are difficult to manage.
B. Preventive and Curative Action
Has preventive (prophylactic) properties by inhibiting fungal spore germination.
Shows curative activity by controlling early-stage infections, making it versatile in disease management strategies.
C. Systemic and Translaminar Movement
Penetrates plant tissue and moves systemically and translaminarly, offering comprehensive protection even in hard-to-reach parts of the plant.
Ensures protection for new growth post-application.
D. Long-Lasting Residual Activity
Provides extended residual protection, reducing the frequency of applications and labor costs.
Useful in integrated pest management (IPM) programs.
E. Low Application Rates
Highly effective at low dose rates, making it cost-effective and minimizing environmental load.
Reduces the risk of phytotoxicity compared to older fungicides.
F. Compatibility and Formulation Flexibility
Available in various formulations including suspension concentrates (SC), wettable granules (WG), and emulsifiable concentrates (EC).
Often used in combination with other fungicides (e.g., tebuconazole, fluopyram) for resistance management.
Conclusion
Trifloxystrobin丨CAS 141517-21-7 is a potent, versatile fungicide with broad-spectrum activity, valued for its preventive, curative, and residual effects. Its ability to move systemically and translaminarly within plant tissue ensures consistent protection. Widely adopted in agriculture, horticulture, and turf management, it provides effective fungal disease control with low application rates, enhancing crop health and yield. While its targeted mode of action offers precision, responsible use and resistance management strategies are essential to preserve its long-term efficacy.
