Three pesticides (2,4-D, basalin, aldrin) inhibited L-methionine-DL-sulfoximine (MSX)-induced photoproduction of ammonia by the nitrogen-fixing cyanobacterium Nostoc linckia. Combinations of pesticides and MSX were inhibitory except at low concentrations (100 and 500 micrograms/ml) of 2,4-D which stimulated NH+4 production. Similar results
Basalin, a herbicide, was administered orally to male rats at doses ranging from 60 mg to 1.92 g/kg for 13 weeks. Oral LD50 of the compound was 1.65 g/kg. Toxic effects included hyperexcitability and tremors. The cumulative lethal dose (CLD50)
Cultured human lymphocytes were exposed to three different concentrations (2.5, 5.0 and 10.0 micrograms/ml) of fluchloralin for 24 and 48 h to assess chromosomal aberrations. A significant dose-dependent increase of chromatid type aberration was observed in these cells. Multiple aberrations

The photodegradation of fluchloralin by UV irradiation or sunlight in aqueous methanolic solution has been examined. In the presence of titanium dioxide five photoproducts were obtained, but only four in its absence. One photoproduct, 2, 2'-azoxy-bis(alpha,alpha,alpha-trifluoro-6-nitro-p-toluidine) is reported for the

The genotoxic and cytotoxic effects of a widely used herbicide, fluchloralin, were assessed using cultured mammalian cells. Treatment of cells for 8-12 hr with fluchloralin resulted in a significant increase in the frequency of metaphase cells with chromosomal damage. At
