Virus 250 EC

Mastering crop resilience: Using Virut 250 EC

Managing lodging is one of the most critical tasks when aiming for high yields in winter wheat and barley. We’ve integrated Syngenta’s Virut 250 EC into our crop management routine because it consistently delivers on its promise: stronger, shorter stems that stand tall until harvest. The active ingredient, trinexapac-ethyl, works systemically, signaling the plant to divert its energy from vertical growth into lateral strengthening and cell wall development.

Application Insights

We typically apply this growth regulator during the tillering stage. Depending on the crop density, our dosage rate ranges from 0.4 to 0.8 L/ha. Since the label allows only one application per season, we ensure it’s perfectly timed. The product’s emulsifiable concentrate (EC) formulation is highly user-friendly—it mixes smoothly in the spray tank and shows excellent compatibility with our fungicides and herbicides, ensuring we don’t lose time on nozzle blockages or tank agitation issues.

Field Performance

• Stem Integrity: The reduction in height is accompanied by an increase in stem diameter and structural rigidity. Even under heavy rain or strong wind, the crops remain upright.
• Disease Management: By keeping the canopy open and firm, we improve air circulation, which helps manage the moisture levels that trigger fungal outbreaks at the stem base.
• Harvest Efficiency: The most tangible benefit shows up at harvest time. Straight, non-lodged crops allow for higher combine speeds and significantly reduce header losses.

Working with Virut 250 EC feels like an insurance policy for our yield. It’s a precise, professional tool from Syngenta that takes the unpredictability out of the pre-harvest period.
