Checker Xtend 39 WG

Systemic Protection for Cereals: An Expert Look at Checkker Xtend 39 WG

When it comes to controlling a broad spectrum of broad-leaved weeds in winter cereals, professional farmers look for solutions that combine high selectivity for the crop with aggressive performance against weeds. Checkker Xtend 39 WG is a systemic insurance herbicide from Bayer, recognized for its effectiveness and safety in wheat and barley cultivation programs.

The formulation includes amidosulfuron, iodosulfuron-methyl-sodium, and diflufenican, balanced by the safener mefenpyr-diethyl. This combination allows for a systemic approach: the herbicide penetrates through the leaves, blocking vital metabolic processes in weeds, while the safener enables the crop to quickly metabolize the active ingredients, preventing phytotoxicity even under challenging environmental conditions.

Key Benefits for Effective Weed Management

• High Selectivity: Specifically engineered for winter cereals to ensure stress-free crop development.
• Broad Spectrum: Effectively manages problem weeds, including common lambsquarters, cleavers, scentless chamomile, shepherd's purse, and cornflower.
• Convenient Formulation: Water-dispersible granules ensure easy preparation of tank mixes and uniform coverage of leaf surfaces.

The application of this herbicide is most effective during the active growth phases of weeds. Due to its systemic nature, it works efficiently on both young and more mature weeds, preventing competition for nutrients during the critical early stages of crop development. Adhering to the recommended application rate of 0.16–0.2 kg/ha in a single treatment allows agronomists to maintain clean fields, which is essential for realizing the full genetic potential of winter crops.
