Pot and field experiments showed that spraying plants in healthy 

 condition resulted in increased yield. In no case will injury 

 result from spraying.

A 15,% solution S. of I. did not touch the weed; 20% solution 



did.

S. of I. was recommended in the Weiner illustr. Gartenz. 1897, 



S. 388. 



Powdered S. of I. mixed with dry soil or sand and on damp days 



or after sunset spread evenly on the surface of the ground, kills

Effect of S. of I. solutions on Charlock growing in soil deficient 



in lime and on that abundantly supplied with lime. In the first 



case spraying with 10-15% solution produced no result, while in 



the second case a spray of 10% solution quickly killed the plant.
