The larvae of Lepidoptera insects and many other pests exhibit exceptionally high sensitivity. This compound demonstrates both stomach poison and contact-killing effects, yielding remarkable efficacy at very low dosages. Moreover, it exerts no detrimental impact on beneficial insects during pest control, thus favoring comprehensive pest management. Additionally, it broadens the spectrum of insecticidal targets while minimizing toxicity to humans and animals. With the highest level of activity, a broad insecticidal spectrum, and no resistance, it combines stomach poison and contact-killing effects, displaying the greatest potency against mites, Lepidoptera, and Coleoptera pests.

Application/Usage: This insecticide functions through the stimulation of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). It is non-systemic and achieves penetration into leaf tissues via translaminar movement. It induces paralysis in Lepidoptera and Coleoptera pests, halting their feeding shortly after ingestion and leading to death within 2-4 days. It is employed for Lepidoptera and Coleoptera control in vegetables, brassicas, and cotton at rates of up to 16 g/ha, as well as in fruit trees and pine trees at rates ranging from 5 to 25 g/ha.
