3,3-Dichloro-1-propene

BeschreibungBecause of the relative lack of nematicidal activity in 1,2-dichloropropane and the desire to eliminate groundwater contamination by a compound not useful for nematode control, 1,3-D became a highly successful nematicide. Although it also has fungicidal activity and insecticidal activity against wireworms in particular, the primary use of the compound is as a nematicide. On a weight basis, 1,3-D is the sixth most abundantly used pesticide in the United States (11); 1,3-D is classified as a possible or probable human carcinogen. Commercial formulations are liquids and contain two isomers. In one series of experiments, aqueous trans-1,3-D was 60% as toxic as the cis isomer, whereas in the vapor phase, trans-1,3-D was 90% as toxic as cis-1,3-D (12). In laboratory experiments simulating field situations, the trans isomer was completely ineffective against the potato cyst nematode Globodera rostochiensis (13).
