INSECT PESTS 



There is nothing connected with the subject of 

 fruit growing that is of more importance than a knoMd- 

 eclge of the habits of the insect and fungous pests that 

 we have to contend with and how to prevent their 

 injury. It is a comparatively easy matter to make the 

 trees grow, and perhaps to set a large crop of fruit, but 

 if this fruit is injured by insects or fungous pests, it 

 will not be salable at paying prices. With the increase 

 of the number of trees or fruit plants in any given 

 locality comes an increase in the number of these pests, 

 and the successful fruit grower must equip himself with 

 spraying outfits and make use of insecticides and fungi- 

 cides if he will insure the quantity and quality of his 

 fruit crop. 



No attempt will be made to describe the various 

 ])ests with scientific accuracy, but to show them as they 

 will be seen by the practical fruit grower. 



PREVENTIVES 



The first consideration in growing good fruit is 

 to so grow the trees or plants that they will be the 

 least liable to the attack of insects or fungi. The con- 

 dition of the tree will have a great influence on the 

 amount of injury that will l)e done by these pests. The 

 more vigorous the growth, tlie less will be the injury 

 from fungous diseases, and, to a greater or less degree, 

 that from insects also, as most of the fungi and many 

 of the insects only attack the weak plants. An abun-
