Description

Oryzalin, Dimethyl CAS NO 19044-94-1 is a selective pre-emergent herbicide belonging to the dinitroaniline chemical class. It is valued for its effectiveness in controlling a broad spectrum of annual grasses and broadleaf weeds by inhibiting root and shoot development. This product is essential for agricultural professionals, horticulturists, and formulators seeking reliable, long-lasting residual weed control in crops such as fruit trees, vines, and turf.

Application

• Pre-emergent Herbicide in Agriculture: Primary use for controlling weeds in orchards (e.g., citrus, pome fruits), vineyards, and nut crops.
• Turf and Ornamental Management: Used on established turfgrass, golf courses, and ornamental landscapes to prevent weed germination.
• Industrial Vegetation Control: Application on non-crop areas such as rights-of-way, fence lines, and storage yards.
• Formulation Intermediate: Serves as a key active ingredient in the manufacturing of professional-grade herbicide formulations.
• Research and Development: Utilized in agrochemical R&D for studying herbicidal modes of action and developing new crop protection solutions.
