CHAPTEK V. 



PROPRIETARY INSECTICIDES AND 

 FUNGICIDES, ETC. 



In this chapter we propose to describe a few of the 

 specially-prepared nisecticides and fungicides on the 

 market, in order that those who do not care to undertake 

 Ihe trouble and time necessary to make their own pre- 

 parations from the formul£e given in preceding chapters 

 may know what kinds are available for winter, spring, 

 and summer spraying. We may add that the prepara- 

 tions about to be mentioned may be obtained from any 

 nurseryman, or seedsman, or dealer in garden sundries.
