Description

Fensulphothion CAS NO 115-91-3 is a potent organophosphate insecticide and acaricide known for its systemic and contact action. This compound is critical for providing effective, long-lasting control of a broad spectrum of soil-dwelling and foliar pests. It is primarily required by the agricultural sector for crop protection and by professional pest control operators for managing persistent insect populations in non-crop areas.

Application

• Agricultural Crop Protection: Systemic control of nematodes, soil insects, and certain foliar pests in a variety of crops.
• Soil Treatment: Applied to soil for pre-plant or at-planting protection against root-feeding organisms.
• Non-Crop Area Pest Management: Used in professional pest control for areas such as turf, nurseries, and around agricultural buildings.
• Seed Treatment Formulations: Incorporated into coatings to protect seeds and young seedlings from early-season insect damage.
• Research & Development: Serves as a reference standard or active ingredient sample in agrochemical R&D and environmental fate studies.
