Orondis Evo 262 SC

Advanced Chemical Composition

Orondis Evo 262 SC is a professional-grade fungicide developed by Syngenta, featuring a unique combination of oxathiapiprolin and azoxystrobin. This dual-action formulation is specifically engineered to target oomycetes, offering superior protection for onion and tomato crops.

Technical Breakdown of the Mechanism

• Oxathiapiprolin represents a breakthrough in disease control. It functions by inhibiting the oxysterol-binding protein (OSBP), which disrupts the pathogen's metabolism at multiple stages of its lifecycle, including spore germination and sporangia formation.
• Azoxystrobin, a member of the strobilurin class, complements this by inhibiting mitochondrial respiration. This combination provides both preventative and curative control, preventing the spread of late blight (phytophthora) and downy mildew (peronosporosis) even in high-pressure environments.

Systemic Protection and Field Application

The product exhibits excellent systemic properties. Its lipophilic nature allows for rapid penetration into plant tissues, ensuring even distribution and long-lasting protection. Formulated as a suspension concentrate, it creates a stable working solution that shows high resistance to rainfall washout shortly after application.

For professional field use on onions and tomatoes, the application rate is set between 0.5 and 1.0 liters per hectare. To ensure long-term efficacy and resistance management, the product is limited to a maximum of 2 treatments per season. Given its classification as a Class 2 hazard, strict adherence to safety protocols and the use of personal protective equipment are mandatory during application.
