Oxycarboxin Frequently Asked Questions
What crops can Oxycarboxin be used on?
Oxycarboxin is primarily registered for use on cereal crops including wheat, barley, and oats. It's particularly effective against rust diseases in these crops. Some formulations may also be approved for use on certain vegetable crops and ornamentals, but always check the product label for specific crop registrations in your region before application.
What is the recommended application rate for Oxycarboxin?
The typical application rate for Oxycarboxin ranges from 0.5 to 1.0 kg of active ingredient per hectare, depending on the target disease and crop stage. For foliar applications, use 200-400 L of water per hectare to ensure good coverage. Always follow the manufacturer's recommendations on the product label, as formulations may vary in concentration and application requirements.
How quickly does Oxycarboxin work after application?
Oxycarboxin begins working immediately after application, with visible effects typically appearing within 24-48 hours. The systemic nature of Oxycarboxin allows it to be absorbed by plant tissues and distributed throughout the plant, providing ongoing protection. For best results, apply at the first signs of disease or as a preventative measure when conditions favor disease development.
Application Guidelines for Oxycarboxin
| Crop | Target Disease | Application Rate | Application Timing |
|---|---|---|---|
| Wheat | Stem rust, leaf rust | 0.5-0.75 kg/ha | Early disease appearance or preventative |
| Barley | Stripe rust, leaf rust | 0.6-0.8 kg/ha | First node detectable (GS31) |
| Oats | Crown rust | 0.5-0.7 kg/ha | Flag leaf emergence |

Additional Oxycarboxin Questions
What is the rainfast period for Oxycarboxin?
Oxycarboxin requires approximately 4 hours to become rainfast after application. During this period, rainfall may reduce effectiveness. For optimal results, apply when rain is not expected for at least 6 hours. The product becomes fully systemic within 24 hours after application.
Can Oxycarboxin be tank-mixed with other products?
Yes, Oxycarboxin is compatible with most commonly used fungicides, insecticides, and adjuvants. However, always perform a jar test before large-scale mixing to check for compatibility. Avoid mixing with strongly alkaline products (pH >8) as this may reduce efficacy. Follow all label instructions regarding tank mixes.
What is the re-entry interval after applying Oxycarboxin?
The standard re-entry interval for Oxycarboxin is 12 hours after application for normal agricultural operations. For tasks involving extensive contact with treated foliage (such as hand harvesting or thinning), wait at least 24 hours. Always follow the specific re-entry period stated on your product label as formulations may vary.
