spray Calendar. 



In the preparation of this calendar the most important points re- 

 garding sprays have been selected and arranged in such a manner 

 that the grower can see at a glance what to apply and when to make 

 the application. The more important insect and fungous enemies 

 are also mentioned, so that a fairly clear understanding of the work 

 can be obtained by examining the table below. When making the 

 application advised, other enemies than those mentioned are also 

 kept under control, for only the serious ones could be named in so 

 brief an outline. The directions have been carefully compiled from 

 the latest results obtained by leading horticulturists and entomologists, 

 and they may be followed with safety. 



Notice. — In this calendar it will be seen that some applications 

 are in parentheses and these are the ones which are least important. 

 The number of applications given in each case has particular refer- 

 ence to localities in which fungous and insect enemies are most 

 abundant. If the crops are not troubled when some applications 

 are advised, it is unnececsary to make any. It should be remem- 

 bered that in all cases success is dependent upon the exercise of 

 proper judgment in making applications. Know the enemy to be 

 destroyed ; know the remedies that are most effective; and finally, 

 apply them at the proper season. 'Be prompt^ thorough ^diXidi persist- 

 ent. Knowledge and good judgment are more necessary to success 

 than any definite rules. See Bulletin 101.
