R. & J. FARQUHAR <5r» CO.'S SEED CATALOGUE. 



SPRAYING CALENDAR, 



In this calendar it will be seen that some applications are italicised and these are the ones which are -most important. The number ©i 

 applications given in each case has particular reference to localities in which fungous and insect enemies are most abundant. If ycur crops 

 are not treubled when some applications are advised, it is unnecessary to make any. It should be remembered 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 and persistent. Knowledge and good judgment are 

 more necessary to success than any definite rules which can be laid down.
