Summary and Conolusions. 



As green arsenite will remain suspended in water a longer time 

 than Paris green, it can be applied more evenly to the foliage and 

 requires much less stirring in the tank. 



The experiments have not yet been carried far enough to deter- 

 mine whether green arsenite is an equally effective insecticide 

 with Paris green. From the expeiiiiients above mentioned, how- 

 ever, this poison seems to have considerable insecticidal value. 



Green arsenite will not burn the foliage of potato vines when 

 used without lime at a strength of one pound to 150 gallons of 

 water.
