Grinfort Harni

Action Mechanism and Selectivity of Grinfort Kharni

The efficiency of this herbicide is rooted in the action of thifensulfuron-methyl, which provides systemic control over weeds in soybean crops. This compound belongs to the sulfonylurea class and acts as a powerful inhibitor of the acetolactate synthase (ALS) enzyme. In practical agricultural terms, this leads to the blockage of essential amino acid synthesis (valine and isoleucine), resulting in the rapid cessation of growth in susceptible weed species.

A critical technical advantage is the product's selectivity. Soybean plants possess the ability to metabolize the active ingredient, neutralizing it into harmless compounds, while weeds lack such defensive mechanisms. This allows Grinfort Kharni to be used as a post-emergence insurance herbicide, effectively cleaning fields from a wide spectrum of broad-leaved weeds.

Formulation and Technical Specifications

The aqueous suspension concentrate formulation is optimized for creating a stable working solution. The integrated system of surfactants facilitates rapid penetration of thifensulfuron-methyl through the leaf cuticle directly to the weed's growth points.

• Control Spectrum: Reliable control of common lambsquarters, redroot pigweed, field mustard, wild radish, shepherd's purse, common chickweed, scentless mayweed, and common ragweed.
• Application Rates: Extremely efficient dosage (6–8 grams per hectare) optimizes logistics and storage costs.
• Regulatory Compliance: Limited to one application per season, requiring strict monitoring of weed and crop growth stages.

The production chain, involving the expertise of TRUSTCHEM (Nanjing), the manufacturing facilities of Shanghai MIO Chemical, and distribution by Agromaksi with Ukragrokom as the applicant, ensures high purity of the active ingredient. The systemic nature of the herbicide ensures deep penetration into weed tissues, preventing regrowth even under challenging weather conditions following application.
