Mesotrione + Atrazine 55% SC Herbicide

This indexed page is retained as a formulation-family overview for suspension-concentrate herbicides combining mesotrione and atrazine at 55% total declared active content. It helps professional buyers compare total-active specifications without assuming that every 55% SC offer uses the same component ratio. The individual content of each active ingredient must be stated on the quotation, product specification, certificate of analysis and proposed label before two offers can be treated as comparable.

Why the component ratio must be confirmed

A total value such as 55% does not by itself identify how much atrazine and mesotrione the finished product contains. Buyers who require the specific Atrazine 50% + Mesotrione 5% SC configuration should use the dedicated exact-formulation page and request documents that repeat that ratio. Other ratios, concentration bases or formulation types are different commercial products and may require separate registration, testing, packaging and label review.

Technical identity and resistance-management context

PubChem provides separate chemical-identity records for atrazine and mesotrione. HRAC places atrazine in Group 5 and mesotrione in Group 27. These classifications can support technical discussion, but the presence of two active ingredients does not create a universal use authorization or guarantee resistance outcomes. Approved crops, target weeds, rates, timing, rotation statements and safety requirements must be taken from the destination-market registration and label.

Procurement documents and quotation scope

For a comparable quotation, state the required component ratio, concentration basis, SC quality parameters, pack sizes, label language, destination and document requirements. Ask for the current product specification, available SDS, certificate-of-analysis format and proposed label before confirming an order. Packaging images on this family page are reference presentations only. Final container, artwork, carton configuration, MOQ, lead time and shipment documents are confirmed against the exact formulation selected by the buyer.

Registration boundary

Registration status is market-specific. This formulation-family page does not imply that every Mesotrione + Atrazine 55% SC ratio is approved in every country. Importers should confirm the exact active ratio, intended claims, packaging and documentation with the competent destination authority before import, sale or use.
