Orus 250 g/L

Reliable disease control for winter crops

Managing winter wheat, barley, or rapeseed fields requires a fungicide you can count on. Orius 250 EW from F. Makhteshim Chemical Works has become my go-to systemic solution. When you deal with rusts, septoria, or phomopsis, you don't want to experiment; you need a stable, high-quality tebuconazole formulation that penetrates plant tissues quickly and stays active.

Field performance and handling

The formulation of Orius 250 EW makes it very easy to work with. Since it comes as an aqueous emulsion, it mixes perfectly in the spray tank. I haven’t faced any issues with clogged nozzles or residue buildup, which is a big relief during the busy spraying season. On wheat and barley, it keeps stem and brown rust under control effectively. For winter rapeseed, it’s essential for managing phomopsis and cylindrosporium.

Application and technical details

• Active ingredient: Tebuconazole 250 g/l.
• Application rate: 0.5–1 l/ha, depending on the pressure and growth stage.
• Flexibility: It works well with 1–2 applications per season, providing a long-lasting protective window.
• Safety: Classified as hazard class 3. Standard PPE is mandatory, but the liquid formulation is convenient to handle without excessive dust or aggression toward equipment seals.

With a 30-day pre-harvest interval, timing is key to ensure compliance and quality. I’ve found that by sticking to the recommended rates, the product provides excellent value for money by preventing significant yield losses. If you are looking for a straightforward, systemic product from a trusted manufacturer like F. Makhteshim Chemical Works, this is definitely a tool to keep in your storage.
