RICH, EC, (Halisulfoprop-ethyl, 125 g/l)

Mechanism of Selectivity and Systemic Activity

RICH, EC is a highly specialized systemic herbicide engineered to manage grass weeds in rapeseed and rice crops. Formulated with quizalofop-P-ethyl at a concentration of 125 g/l, this product belongs to the aryloxyphenoxypropionate chemical group. Its primary function is the rapid systemic translocation via the phloem, targeting the growing points of susceptible weed species.

Technical Specifications and Performance

The product functions as an inhibitor of the acetyl-CoA carboxylase enzyme (ACCase). By disrupting the synthesis of fatty acids, it effectively halts cell division within the meristematic tissues of grasses. The Emulsifiable Concentrate (EC) formulation is critical for its field performance:

• Optimal Adhesion: The formula enhances leaf surface coverage, ensuring rapid uptake even under variable environmental conditions.
• Translocation Efficiency: Once absorbed, the active ingredient moves swiftly to the roots and rhizomes, preventing regrowth.
• Metabolic Selectivity: Rapeseed and rice crops demonstrate the ability to metabolically neutralize the herbicide, whereas grass weeds succumb to lipid metabolism failure.

Designed as a post-emergence foliar herbicide, RICH allows for flexible application windows during the active growth phase of target weeds. Manufactured by Shandong Qiaochang Chemical Co., Ltd., the product maintains high formulation stability, which is crucial for uniform distribution in the spray tank and consistent field efficacy.

Operational Practicality

Classified under Hazard Class 3, it requires standard safety protocols during handling and application. Its selective nature makes it an essential tool in integrated weed management (IWM) strategies, particularly where grass weed pressure threatens yield potential in oilseed rape and rice cultivation.
