Technical Overview of Shturval Herbicide

Shturval is a systemic herbicide featuring tribenuron-methyl as its active ingredient, designed specifically for selective weed control in cereal crops. Belonging to the sulfonylurea chemical class, its primary technical function is the inhibition of the acetolactate synthase (ALS) enzyme. This disruption halts the production of essential amino acids, causing immediate growth cessation in target weeds. Unlike contact herbicides, Shturval travels through the plant's vascular system, ensuring that even deep-rooted species are targeted effectively.

Formulation and Application Performance

The product is supplied as water-dispersible granules (WG). This specific formulation is engineered for rapid dissolution, ensuring uniform concentration throughout the spray tank and preventing nozzle clogging—a critical factor for precision farming. The systemic nature of the herbicide ensures that the active substance reaches the meristematic tissues, which is essential for managing aggressive weeds like creeping thistle (Cirsium arvense) and common ragweed (Ambrosia artemisiifolia).

Efficiency and Crop Safety

• Selective Action: Designed primarily for winter and spring wheat and winter barley, Shturval demonstrates high selectivity. The crop metabolizes the active compound into inactive forms, ensuring safety for the cultivated plant while maintaining high lethality against susceptible broad-leaved weeds.
• Application Rates: With a precise dosage range of 0.015–0.025 kg/ha, it is a high-potency solution that requires accurate calibration. Its post-emergence application timing allows the agronomist to target the specific weed population during its most vulnerable vegetative stage.
• Usage Constraints: The product is labeled for a single application per season, making it a strategic choice for pre-planned pest management cycles.

Shturval represents a reliable, cost-effective tool for integrated weed management. As a Class III hazard substance, it requires standard protective protocols during handling, but its high efficacy against a broad spectrum of weeds and the absence of residual limitations for following crops make it a cornerstone for efficient cereal production.
