Reliable Protection for Cereals: How Challenger Works

When you head out to the field in spring and spot early signs of cereal flies or aphids on your wheat or barley, there is no time to waste. It is a dual-component insecticide where the systemic action of thiamethoxam meets the contact impact of lambda-cyhalothrin. This synergy provides an immediate knockdown effect combined with long-lasting residual protection.

Field Experience and Dosage

The product comes as a suspension concentrate, which significantly simplifies the mixing process. It blends perfectly, does not clog sprayer nozzles, and eliminates any hassle when preparing tank mixtures. With winter crops:

• The application rate of 0.15–0.25 L/ha allows for flexible intensity adjustment based on the economic threshold.
• Two applications per season are more than enough to maintain full control.
• The product shows excellent efficacy against a wide spectrum of pests: from thrips and leafhoppers to cereal leaf beetles.

The systemic nature of the product allows the active ingredients to penetrate plant tissues, meaning even pests hiding in leaf axils are effectively neutralized. It is important to note that this is a Class 3 hazard substance, so standard safety protocols while operating the sprayer are mandatory—always follow the label instructions and wear proper protective equipment.
