DEVRINOL, CS

Napropamide Mechanism: Subsurface Weed Control

«DEVRINOL, SC» utilizes napropamide, an amide-class active ingredient that shifts the weed management paradigm in tomato cultivation. Unlike foliar herbicides, napropamide operates exclusively within the soil profile, targeting the germination zone. It acts as a selective systemic herbicide that inhibits meristematic activity, effectively halting root and hypocotyl development in emerging weeds. By preventing germination before the weeds even break the soil surface, it eliminates early-season competition for nutrients and water, giving tomato crops an essential advantage.

Technical Specifications and Application Insights

• Soil Barrier Technology: The product is designed to form a consistent protection layer in the topsoil. Success relies on precise application, with recommended rates of 2–4 L/ha to achieve the necessary concentration to inhibit both annual grasses and broadleaf weeds.
• Systemic Selectivity: The herbicide displays high selectivity for tomatoes. When applied according to protocol, the crop safely metabolizes the substance, while susceptible weed species succumb upon root uptake.
• SC Formulation Stability: The Suspension Concentrate (SC) formulation ensures superior physical stability in the spray tank and uniform coverage of the soil surface. This consistency is vital for maintaining the integrity of the protective soil barrier.

Implementation Guidelines

As a pre-emergence herbicide, «DEVRINOL, SC» must be applied before the crop and weeds emerge. The formulation, produced under the quality standards of UPL Limited (India/Vietnam facilities), provides a reliable, non-volatile solution. A maximum of one application per season is permitted, necessitating precise calibration to maintain weed-free conditions throughout the critical growth stage. With a pre-harvest interval of 30 days, it is a highly effective tool for professional tomato management, provided the application window is strictly observed.
