3-Methyl-4-nitrophenyl

Photooxidation of parathion also occurred on leaf surfaces (18), together with isomerization and other reactions. Fenitro-thion (j),O-dimethyl 0-3-methyl-4-nitrophenyl phosphorothionate) and other phosphorothionate insecticides behaved similarly (19). Some pesticides do not require external reagents for photodegradation on surfaces carbamate insecticides such as carbaryl (1-naphthyl li-methylcarbamate), aminocarb (4-dimethylamino-3-methylphenyl li-methylcarbamate), and mexacarbate (4-dimethylamino-... 

In order to evaluate the potential hazards chemical insecticides pose to forest environments, it is essential that adequate and reliable research data be generated on their environmental chemistry (distribution, persistence, movement, metabolic degradation, toxicity, fate, etc.). This paper gives a brief account of some laboratory and field research activities carried out at the Forest Pest Management Institute, Canadian Forestry Service to meet this requirement. Using two chemical insecticides which are extensively used now in forest insect control programs in Canada Viz aminocarb [Trade name, Matacil 4-dimethylamino-m-tolyl N-methylcarbamate] and fenitrothion [0,0-dimethyl 0-(3-methyl-4-nitrophenyl) phosphorothioate], studies conducted at the Institute to elucidate the environmental behavior and fate of forestry insecticides in general will be discussed.

On the basis of this finding, Czechoslovakian, German and Japanese workers independently developed fenitrothion, which has the chemical composition 0,0-dimethyl-0-(3-methyl-4-nitrophenyl) phosphorothioate (fenitrothion, 28) (Drabek and Pelikan, 1956 Lorenz, 1960 Suzuki et al., 1960).
