VARYAG, KS (metolachlor, 315 g/l + terbuthylazine, 190 g/l)

Stable control of crop cleanliness from day one

When working with corn and sunflower, the main task is to eliminate weed competition before they even emerge. The soil herbicide "Varyag, KS" from the "Fabryka Ahrokhimikativ" (Cherkasy, Ukraine) is a case where one canister solves the protection issue at the critical initial stage. The combination of metolachlor and terbuthylazine works like a double shield: one component controls grasses, while the other handles broadleaf weeds.

Operational nuances

As an operator, I must note that this product requires high-quality soil preparation. A fine-clod structure is the key to a uniform and consistent chemical barrier. Since this is a soil herbicide, it is important not to miss moisture: if the soil is too dry, efficiency drops, so it is best to apply it right before rainfall or incorporate it into the soil. The suspension concentrate form mixes easily and does not clog sprayer filters, which is crucial during long field shifts.

Key takeaways

• Application rate: 4–4.5 L/ha allows for flexibility depending on field weed pressure. On heavy soils or in cases of high weed infestation, use the upper dosage limit.
• Selectivity: It is a selective herbicide. The crop remains safe, and we have observed no phytotoxicity when guidelines are followed.
• Systemic action: The product is absorbed by the weeds' root system, which prevents regrowth after the first rains.

"Varyag" from the Cherkasy-based manufacturer is a predictable tool for those who do not want to spend time on post-emergence remedial treatments. Apply it once before emergence and forget about the problem during the most critical growth period. Given its 3rd hazard class, it is safe to handle following standard protocols; just ensure you follow the regulations and do not exceed the limit of one application per season.
