Orius 25 EW

ORIUS 25EW

ORIUS 25EW is a versatile and potent foliar systemic fungicide designed to provide curative control over a range of fungal diseases affecting various crops such as barley, wheat, cabbages, and French beans. The active ingredient, tebuconazole, belongs to the triazole class of fungicides and operates by inhibiting sterol demethylation, which is vital for fungal cell membrane synthesis.

Features

• ORIUS 25EW is highly effective against multiple fungal pathogens, including leaf rust, net blotch, Helminthosporium spots/blight, and Septoria leaf spot. This broad spectrum control makes it an essential tool for managing fungal diseases in various crops.
• The systemic nature of tebuconazole allows ORIUS 25EW to be absorbed by the plant and distributed evenly throughout the leaf tissue. This ensures comprehensive protection by targeting both existing infections and preventing new infections from establishing.
• ORIUS 25EW not only prevents fungal spores from germinating but also stops the progression of existing infections, making it a versatile solution for disease management. This dual action helps maintain crop health and optimize yields.

Mode of Action

Tebuconazole (250g/L)

Tebuconazole functions as a sterol demethylation inhibitor. By blocking the demethylation process of sterol biosynthesis, it disrupts the formation of the fungal cell membrane, leading to cell leakage and eventual death of the pathogen.

Application

1. Wheat

Rate: 0.75 – 1 L/Ha or 50 – 75 ml/20L of water.

Application Timing: Begin applications when disease signs are first observed and continue at intervals of 3-4 weeks, depending on disease pressure and weather conditions.

2. Barley

Rate: 0.75 L/Ha or 75 ml/20L of water.

Application Timing: Apply at the first signs of disease and follow up as necessary every 3-4 weeks based on disease severity and environmental factors.

Usage Guidelines

1. Stage of Use

Initiate spraying when disease symptoms become apparent. The timing of applications is crucial for optimal disease control, especially when diseases are actively establishing in the field.

2. Tank Mix Compatibility

ORIUS 25EW can be tank mixed with most commonly used insecticides, fungicides, foliar fertilizers, and adjuvants, except for strongly alkaline compounds. This compatibility allows for integrated pest and disease management practices, enhancing overall crop protection.

Target Pests/Pathogens

Leaf Rust: Affects wheat and barley, causing yellow to orange pustules on leaves and reducing photosynthetic capacity.

Net Blotch: Common in barley, characterized by dark, net-like lesions on leaves.

Helminthosporium Spots/Blight: Causes lesions and blights on leaves of various crops, including barley and wheat.

Septoria Leaf Spot: Affects wheat and other crops, leading to necrotic leaf spots that reduce green leaf area and yield.

Environmental and Safety Considerations

Safety: When used according to label instructions, ORIUS 25EW poses minimal risk to non-target organisms and the environment. Adhering to recommended rates and application intervals is essential for effective and safe use.
