Description

D-Tetramethrin is a potent synthetic pyrethroid insecticide known for its fast-acting knockdown effect against a wide range of flying insects. This compound is a key isomer in the tetramethrin mixture, valued for its enhanced efficacy and stability in formulated products. It is primarily utilized by manufacturers in the agrochemical and public health sectors to produce household insecticides, aerosol sprays, and mosquito coils for effective pest control.

Application

• Household Insecticide Formulations: A core active ingredient in aerosol sprays, electric vaporizer mats, and mosquito coils for rapid knockdown of flies, mosquitoes, and moths.
• Public Health Pest Control: Used in space sprays and fogging formulations for the management of disease-vector insects in community and institutional settings.
• Agricultural Pest Management: Incorporated into insecticide mixtures for the protection of stored grains and certain crops from flying insect pests.
• Animal Health Products: Found in formulations for premises and environmental control of flying pests around livestock and pets.
• Industrial & Residential Fogging: Employed in professional pest control operations for area-wide disinsection.
