Description

Demeton-S-Methyl CAS NO 919-86-8 is a systemic organophosphorus insecticide and acaricide. It is valued for its effective control of a broad spectrum of sucking and mining insects and mites in various agricultural systems. This compound is primarily used by agrochemical formulators and manufacturers for crop protection. Its systemic action allows it to be absorbed and translocated within the plant, providing lasting residual activity.

Application

• Agricultural Insecticide: Systemic control of aphids, spider mites, thrips, and whiteflies on a wide range of crops including cotton, vegetables, and fruits.
• Acaricide Formulations: Key active ingredient in miticide products for managing mite infestations in orchards and greenhouses.
• Seed Treatment: Used in formulations for protecting seeds and young seedlings from early-season pest damage.
• Pest Management in Horticulture: Integrated into spray programs for ornamental plants and nursery stock.
• Technical Grade Material: Serves as a primary intermediate for the synthesis of other pesticide formulations and related chemical products.
