Amistar Extra 280 SC

Synergistic Control: The Science of Amistar Extra 280 SC

The systemic fungicide Amistar Extra 280 SC by Syngenta is a sophisticated chemical solution designed to tackle a broad spectrum of fungal pathogens. By integrating the properties of two distinct chemical classes—strobilurins and triazoles—it provides both preventive and curative control across various agricultural crops.

Core Components and Their Functions

• Azoxystrobin: A member of the strobilurin group, it works by inhibiting mitochondrial respiration in fungi, effectively starving the pathogen of energy. Beyond its fungicidal role, it is known for the "greening effect," which delays leaf senescence and optimizes nitrogen uptake.
• Cyproconazole: A triazole component that inhibits the biosynthesis of ergosterol. It penetrates plant tissue rapidly, halting mycelial growth and spore development, which is essential for controlling rusts and spot diseases.

Operational Efficiency in the Field

Supplied as a suspension concentrate, this formulation ensures excellent coverage and adhesion to leaf surfaces. With an application rate of 0.5 to 1.0 L/ha, Amistar Extra 280 SC is highly effective against Alternaria, Sclerotinia, white mold, gray mold, and various leaf spots in crops such as winter wheat, barley, soybean, and rapeseed. Its systemic nature ensures that active ingredients are distributed within the plant, offering protection to new growth.

Application Protocols

Farmers must adhere to the limit of two applications per season to maintain product efficacy and manage resistance. A pre-harvest interval (PHI) of 30 days must be strictly observed. Classified as a Hazard Class 3 substance, the fungicide requires standardized safety measures during handling and application to ensure operator protection.
