abstract |
The invention relates to novel phosphorothiolates or phosphorothionothiolates of O-ethyl, S-n-propyl and 0-2,2,2-trihalogenethyl. These compounds are prepared by a process, one of the variants of which consists in reacting thio (or dithio) phosphoryl halides with trihalogenethanols. The new compounds of the invention are endowed with remarkable insecticidal, acaricidal and nematicidal activity; they can be used as pesticides in plant protection. |
