Rice, wheat (Rothwell Perdix), and apples (Ellison's Orange) 
were grown in a glasshouse in soil treated with 14¢_chlorothiamid 
(Prefix). Dichlorobenzonitrile and the benzamide were found in the 
soil, rice stems and leaves, and apple leaves. The benzamide was also 
found in wheat grain, straw and leaves. In extracts of wheat, 3-hydroxy- 
2,6-dichlorobenzamide was identified both before and after treatment with 
B-glucosidase. After treatment of apple leaves with 140-2 ,6-dichloro- 
benzamide, the glycosidic material was shown to contain two components. 
One was identified as the B-D-glucoside of 3-hydroxy-2,6-dichlorobenzamid. 
The other was a glycoside of the same aglycone with a sugar other than 
B-D-glucose. The 3-hydroxy- and 4-hydroxy-2,6-dichlorobenzontriles were 
identified in apple leaf and wheat leaf after enzymic hydrolysis (1765, 
1766, 1767).
