the fruiting season is over. In any case it is to be presumed that 

 tlie best of attention will be given to cultivation. 



Mr. Hosnier's plantation will be treated during the season of 1896 

 in the same manner as before, and the results obtained will be 

 published at the close of the season. 



IV. TREATMENT OF COMMON DISEASES AND IN- 

 SECTS INJURIOUS TO FRUITS AND VEGETABLES. 



This subject is here discussed for the purpose of giving plain 

 directions for treating some of the common diseases and insects in- 

 jurious to fruits and vegetables in New York State, either by spray- 

 ing or otherwise. It is composed of four articles, namely : 



1. Common Diseases and Insects Injurious to Fruits. 



2. Common Diseases and Insects Injurious to Vegetables. 



3. Common Diseases and Insects Injurious to Nursery Stock. 

 4:. Fungicides and Insecticides. 



By consulting the index the reader will readily find any subject 

 that is here treated. The principal subjects in each article are pre- 

 sented in alphabetical order and under each fruit or vegetable the 

 diseases are first considered and then the insects. 



An account is first given of the common appearance or charac- 

 ters of the disease or insect and of the injuries caused by it when- 

 ever it is thought necessary to do so in order that the reader may 

 know just what insect or disease is meant. Then a remedy or line 

 of treatment is "recommended" or "suggested." Nothing is 

 " recommended" that has not proved good under trial. Remedies 

 or lines of treatment are simply " suggested " whenever they have 

 not been tested sufliciently to permit of their being confidently 

 recommended. Recommendations quoted from other authors are 

 given simply on their authority. In describing the appearance of 

 insects or giving their life histories Saunder's Insects Injurious to 

 Fruits has been freely consulted. Other authors are given credit in 

 foot notes.
