CHAPTER XV 



INSECTS AND FUNGI ATTACKING ORNAMENTAL 

 TREES, SHRUBS, ETC. 



ONE of the greatest difficulties one has to contend with 

 in the care of ornamental trees, shrubs, etc., is the injury 

 caused by insects and fungous pests, and in this chapter a 

 brief outline of the most destructive pests will be given, 

 with the best and most easily applied remedies. 



The injury done to ornamentals by the above pests is very 

 great, though not so large as that to fruit and garden crops. 

 It is the history of all cultivated plants that the longer and 

 more largely any one kind is grown the more rapidly will its 

 natural enemies, i.e., insects and parasitic fungi, increase, 

 and the more ornamental homes we have the more need 

 there will be to resort to protective or remedial measures to 

 secure satisfactory growth. 



No attempt will be made at a strictly technical descrip- 

 tion of species, but the author will endeavor to give a brief, 

 plain description such as will enable the practical gardener 

 or home-owner to detect the pests that may be injuring his 

 pets and to apply remedies that shall save them from de- 

 struction. 



In making up this list the author is indebted to the many 

 carefully recorded results given in the bulletins of the 

 experiment-stations published by several States, which 

 together with a large practical experience in the care of 

 nearly all species and varieties of ornamental trees, shrubs, 

 etc., he hopes will enable him to present the latest and best
