Description

Oryzalin is a selective pre-emergent dinitroaniline herbicide known for its long-lasting soil residual activity. Its primary value lies in providing effective, broad-spectrum control of annual grasses and broadleaf weeds by inhibiting microtubule assembly during cell division. This product is essential for agricultural professionals, turf managers, and industrial formulators seeking reliable, persistent weed management solutions in crops like fruit orchards, vineyards, and non-crop areas.

Application

• Selective Herbicide in Agriculture: Pre-emergent control of weeds in established fruit orchards (e.g., citrus, pome fruits), vineyards, nut trees, and berry crops.
• Turf and Ornamental Management: Used in professional turfgrass settings and ornamental nurseries to prevent weed germination without harming established desirable plants.
• Industrial Vegetation Control: Application in non-crop areas such as rights-of-way, fence lines, and industrial sites for long-term vegetation suppression.
• Research and Development: Serves as a critical reference standard and active ingredient in agrochemical R&D for developing new formulations and studying herbicide action.
• Manufacturing of Agrochemicals: Used as a technical-grade active ingredient by formulators to produce various commercial herbicide products (e.g., liquids, granules).
