Prograd

Mechanism of Action and Selectivity

The core of the product is prometryn, a triazine-class active ingredient. As a systemic, selective herbicide, "Prograd" inhibits the Hill reaction, effectively blocking photosynthesis within target weed species. For agricultural professionals, it is vital to note that selectivity is achieved through the ability of the crop plants (soybeans, sunflowers, carrots, coriander) to metabolize prometryn into non-toxic compounds before the substance interferes with the culture’s enzymatic systems.

Technical Specifications and Soil Activity

The formulation is delivered as a suspension concentrate. This chemical-physical structure ensures uniform particle distribution within the working solution and predictable behavior within the soil profile. Acting as a soil-applied herbicide, "Prograd" establishes a protective barrier in the top soil layer (0–5 cm). It is in this precise zone that annual broad-leaved and certain grass weed seeds germinate, absorbing the prometryn through their emerging sprouts and root systems.

Practical Application Guidelines

• Timing: Strictly pre-emergence application. Maximum efficacy is achieved when soil moisture is adequate, as it is necessary for activating the herbicide and facilitating its uptake by the root systems of weeds.
• Protection Technology: The use of this herbicide eliminates weed competition during critical early growth stages. Since the application is performed once before crop emergence, it significantly reduces stress on the developing plants.
• Quality Assurance: Produced by F.Superus Co., Ltd., the product exhibits high formulation stability, provided that storage and master-batch preparation guidelines are strictly followed.

When handling this Hazard Class 2 product, it is essential to adhere to safety protocols regarding personal protective equipment and dosage rates specified by the registrant, Rangoli, Ukraine. Proper seedbed preparation is mandatory; the presence of large soil clods reduces the integrity of the "protective shield," which can lead to patchy weed emergence.
