foliage, unless lime is added. Partis green and Bordeaux mixture 

 ■can, he applied together with perfect safety. Use at the rate of 4 

 ounces of the arsenites to 50 gallons of the mixture. The action 

 of neither is weakened, and the Paris green loses all caustic proper- 

 ties. For insects which chew. 



London Purple. 



This is used in the same proportion as Paris green, but as it is 

 more caustic it should be applied with two or three times its weight 

 of lime, or with the Bordeaux mixture. The composition of Lon- 

 don purple is exceedingly variable, and unless good reasons exist 

 for supposing that it contains as much arsenic as Paris green, use 

 the latter poison. Do not use London purple on peach or plum 

 trees unless considerable lime is added. For insects which chew. 



Hellebore. 



Fresh white hellebore 1 ounce 



"Water 3 gallons 



»' 



Apply when thoroughly mixed. This poison is not so energetic 

 as the arsenites and may be used a short time before the sprayed 

 portions are harvested. For insects which chew. 



Kerosene Emulsion. 



Hard soap i pound 



Boiling water 1 gallon 



Kerosene 2 gallons 



Dissolve the soap in the water, add the kerosene, and churn with 

 a pump for 5-10 minutes. Dilute 10 to 25 times before applying. 

 Use strong emulsion, diluted 4 times in winter, for all scale insects. 

 For insects which suck, as plant lice, mealy bugs, red spider, thrips, 

 bark lice or scale. Cabbage worms, currant worms and all insects 

 which have soft bodies, can also be successfully treated.
