386 STEGLICH, ( ).— (Why Sulphate of Iron kills Mus- 



tard.) 



Sachs. Landw. Ztschr. (1898), S. 217. 



Explains the action of S. of I. on mustard by assuming that 

 the sulphur in the potassium myronate (C 10 H 18 NS 12 o 

 10 K) combines with iron to form sulphide of iron, thus caus- 

 ing death. Stender points out that Rape (B. napus oleifers) 

 which aiso contains mustard oil is not injured, on the con- 

 trary is rendered more vigorous.
