412 Report of the Entomologists of the 



If directions are carefully followed no ill effects will result from 

 the use of arsenites on cauliflower and lettuce. We assume that 

 men who can read are capable of using some judgment in the use 

 of the resin lime mixture and Paris green. It has been explicitly 

 stated that this mixture should not be used on cabbage after the 

 heads are two-thirds formed; that only skillful and intelligent 

 laborers should be trusted with the application of it on cauli- 

 flowers; that it should never be applied after the "flower" has 

 commenced to form. 



For the varieties of lettuce which form heads, it can be safely 

 used until the plants are one-third grown. It must never be used 

 on other varieties of lettuce.
