ENEMIES 



This little volume is the outcome of suggestions

 a Spraying Calendar is, at the present moment, much 

 needed by fruit growers and gardeners. In the 

 writing, the work has grown somewhat beyond the

 within very modest bounds, and does not profess to 

 give more than a brief and popular account of such 

 fruit tree pests as are more frequently met with in 

 this country, as well as of the commoner insecticides 

 and fungicides used in combating them. 



The spraying of trees has now for many years been 

 recognised abroad and in our colonies as an operation 

 indispensable to fruit-growing, if clean fruit and heavy 

 crops are to be obtained ; and in many cases such 

 spraying is even enforced by law. No doubt the 

 necessity for spraying is not, and may never be, so 

 great in this country as it is elsewhere ; our variable 

 climate, the smallness and highly mixed character of 

 our plantations, as well as the large number of different 

 varieties grown, whilst being disadvantageous in many 

 ways to fruit production, indirectly benefit it, by
