Overview
Terbutryn (CAS 886-50-0 ), also sold under the trade names Igran, Shortstop, and Terbutrex, is a selective triazine herbicide used in both agricultural and non-agricultural settings. It controls broadleaf weeds and grasses by inhibiting photosynthesis in target plants.
This chemical has established use as a biocide in construction materials. In cereal and grain crop production, it is applied pre- and post-emergence to suppress competitive weed species without damaging established crops.
Formulators incorporate it into facade paints, renders, and building material coatings where algae and fungal growth on exterior surfaces must be controlled over extended periods. It is also used in aquatic and industrial water management contexts.
The substance helps to limit algal proliferation in various environments. Herbicide manufacturers include it as an active ingredient in suspension concentrates and wettable powder formulations for both agricultural and industrial end-use markets.
The product is supplied as a technical-grade active ingredient, typically as a solid or powder, for downstream formulation into registered end products. Standard concentrations for technical material are commonly specified at 95% purity or above.
Procurement is primarily directed at agrochemical formulators, biocide manufacturers, and registered product producers operating under applicable regulatory frameworks. This ensures compliance with safety and environmental standards during the manufacturing process.
