Clodinafop-propargyl

Clodinafop-propargyl (CAS 105512-06-9), sold under trade names including Topik and Discover, is a selective post-emergent herbicide used in cereal crop production. It controls grass weeds in wheat and other small grain crops by inhibiting the acetyl-CoA carboxylase enzyme pathway. In wheat cultivation, this active ingredient is formulated into emulsifiable concentrates and wettable powder products for field application against problematic grass weeds such as wild oat and ryegrass. It is commonly co-formulated with safeners to improve crop tolerance.

Agrochemical manufacturers source the technical-grade active ingredient for blending into finished herbicide formulations distributed across major grain-producing markets. This ensures effective weed control while maintaining the safety of the primary cereal crops. Contract formulators also incorporate it into premix products targeting resistance management programs in high-intensity cereal farming regions. These specialized formulations are essential for maintaining long-term efficacy in modern agricultural practices.

The chemical is supplied as a technical-grade active ingredient, typically as a solid or concentrated form for downstream formulation use. Standard purity for technical grade is generally 95% or higher, meeting requirements for agrochemical registration. Packaged quantities range from small drums for development batches to bulk supply for commercial-scale formulation operations. This flexibility allows manufacturers to scale production based on seasonal demand and specific regional requirements.
