 Bordeaux mixture. 



Arsenate of lead or Paris green can be used with 

 Bordeaux mixture or lime-sulphur sprays thus mak- 

 ing a combined fungicide and insecticide treat- 

 ment. Both of these sprays are poisonous and 

 should be kept out of the reach of children. 



There is no danger from burning the foliage with 

 arsenate of lead nor will it wash off when the rain

 or powder form and may be used as a dry powder 

 or made into a solution according to the directions 

 which accompany each package. 



When the cucumber beetle attacks vines, spray 

 with Bordeaux mixture or arsenate of lead solu- 

 tion. Tobacco dust sprinkled over the vines will 

 tend to keep these bugs away. 



Arsenate of lead should be used as a spray when 

 asters are attacked by the aster beetle. Many of 

 these bugs can be picked off by hand and they 

 should be dropped in kerosene emulsion at once.
