2,6-Dichloro-4-nitroaniline 
Dichloro-4-nitroaniline (DCNA) was readily taken up and trans- 
located by both tomato and lettuce and was rapidly degraded to uniden- 
tified polar metabolites. Labeled carbon from pena-cl4 appeared in the 
carbohydrate plant constituents (Lemin, 1965). 
1,3-Dichloropropene, cis- and trans- 
Cis- and trans- 1,3-dichloropropene are hydrolyzed in wet soil to the 
corresponding allyl alcohol (Castro and Belser, 1966). 
Dimefox (DMF, bis(dimethylamido)phosphoryl fluoride) 
Although it is known that dimefox is converted to an anticholin- 
esterase in the liver of rats and in the gut of roaches, no metabolites 
have been identified. By analogy to schradan, the N-oxide can be 
postulated, (Fenwick et al., 1957; Arthur and Casida, 1958).
