Title: Insecticidal and anti-parasitic preparations
IPC: A01N53/00
Filed: 1977-12-09
Abstract: The insecticidal products based on pyrethrins, pyrethrinoids and rotenones paralyse the insect to be destroyed only momentarily. Organochlorine compounds, organophosphates or alkaloids are therefore generally added thereto. But these added products increase the very low toxicity of pyrethrins, pyrethrinoids and rotenones. The organochlorine compounds, organophosphates and alkaloids have therefore been replaced by dimethylformamide. In the control of insects such as lice, a formulation is used containing dimethylformamide in a proportion of about half; in the control of pests living in stables, the formulation may contain up to 90% dimethylformamide.
