Description

Tolfenpyrad CAS NO 129558-76-5 is a potent pyrazole-based insecticide and acaricide belonging to the mitochondrial electron transport inhibitor (METI) class. It matters for its unique mode of action, providing effective control against a broad spectrum of pests, including those resistant to other insecticide classes. This product is essential for agricultural formulators and manufacturers developing crop protection solutions for fruits, vegetables, and ornamental plants.

Application

• Primary use as an active ingredient in agricultural insecticide and acaricide formulations.
• Effective control of spider mites, whiteflies, aphids, thrips, and other sucking pests in various crops.
• Management of pest populations that have developed resistance to organophosphates, pyrethroids, and other conventional insecticides.
• Integrated Pest Management (IPM) programs due to its specific biochemical target site.
• Protection of high-value crops such as fruits (e.g., citrus, pome fruits), vegetables, and ornamentals.
• Use in greenhouse and nursery applications for protected cultivation.
