Description

Oxydemeton-Methyl CAS NO 301-12-2 is a systemic organophosphorus insecticide and acaricide known for its potent action against a range of sap-feeding pests. Its primary value lies in its systemic activity, allowing it to be absorbed and translocated within the plant for longer-lasting protection. This product is essential for agricultural professionals and formulators seeking effective crop protection solutions against aphids, mites, and other sucking insects in various horticultural and agricultural settings.

Application

• Agricultural Crop Protection: Systemic control of aphids, spider mites, whiteflies, and other sucking pests in crops such as cotton, vegetables, fruits, and ornamentals.
• Integrated Pest Management (IPM): Used as a key component in rotation programs to manage pest resistance.
• Professional Horticulture: Protection of greenhouse plants and high-value nursery stock from invasive sap-feeding insects.
• Formulation Ingredient: Serves as a technical-grade active ingredient for the manufacture of emulsifiable concentrates (EC), soluble concentrates (SL), and other commercial pesticide formulations.
• Public Health Pest Control: Historically used in certain regions for controlling disease-vector insects, subject to local regulatory approvals.
