Description

Pyributicarb is a selective pre-emergence herbicide belonging to the carbamate chemical class. Its primary value lies in providing effective, long-lasting control of annual grasses and broadleaf weeds in key agricultural systems. This product is essential for professional growers and formulators seeking reliable crop protection solutions. The compound is identified by the CAS number 88678-67-5.

Application

Pyributicarb is a versatile active ingredient with established use in several major cropping systems. Its primary and related applications include:

• Rice Paddy Herbicide: Pre-emergence control of barnyard grass (*Echinochloa crus-galli*) and other problematic weeds in transplanted and direct-seeded rice.
• Cereal Crop Protection: Used in wheat and barley for managing a spectrum of annual grass and broadleaf weeds.
• Turf and Ornamental Management: Selective weed control in managed turfgrass, golf courses, and ornamental plantings.
• Industrial Vegetation Control: Component in non-crop herbicide formulations for areas like railways, roadsides, and utilities.
• Agrochemical Formulation: A key technical material for manufacturers producing emulsifiable concentrates (EC), wettable powders (WP), and granular (GR) formulations.
• Integrated Weed Management (IWM): A tool in rotation programs to help manage and prevent herbicide resistance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and handling properties. Keep away from heat, sparks, and open flame.
