Description

General description

Chlorfluazuron belongs to the class of benzoylurea (BU) insecticides, with broad-spectrum insecticidal activity. It is widely used for the control of insect pests especially Lepidoptera, affecting food, vegetables, and other crops. BU insecticides are effective insect regulators, since they are highly selective, undergo rapid degradation in environmental matrices, possess high biological activity, and cause low levels of toxicity to humans and animals.

This reference material (RM) is produced and certified in accordance with ISO/IEC 17025. This RM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content incl. uncertainty and expiry date are given on the certificate.
