SPRAYING AS AN ORCHARD PRACTICE. 



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

 ing sprays have been selected and arranged in such manner that the 

 grower can see at a glance what to apply and when to apply it. The 

 more important insects and fungous enemies are also mentioned, so that 

 a fairly clear understanding of the work can be obtained by examining 

 the tables. When making the applications advised, other enemies than 

 those mentioned are also kept under control, for only the most serious 

 ones can be named in so brief an outline. The directions have been care- 

 fully compiled from the latest results of leading investigators. 



In this calendar it will be seen that some applications are in paren- 

 theses : these are the ones that are least important. The number of ap- 

 plications given in each case has particular reference to localities in which 

 fungous and insect enemies are most abundant. If the crops are free 

 from attack when certain applications are advised, it may be unnecessary 

 to make them at these times but prevention in the case of fungous dis- 

 eases should be the watchword. It should be remembered that in all 

 cases success is dependent on the exercise of proper judgment in making 

 applications. Plant diseases are rarely cured, but they can frequently 

 be prevented. Know the enemy to be destroyed and the remedies that 

 are most effective ; then apply at the proper season. Be prompt, thorough 

 and persistent. Knowledge and good judgment are more necessary to 

 success than any definite rules. Spraying is an insurance. 



Spraying is no longer an experiment, but as much an accepted prac- 

 tice, as tillage, and pruning and fertilizing. It may not be necessary to 

 spray every year, but the farmer should be prepared to spray each year. 



See that pumps and rigs are in working order before plowing time 

 comes. Order your materials. Pattern after the bugs : be ready. 



There is no one best pump or nozzle. There are best devices for 

 particular kinds of work, depending on the size of plants to be sprayed, 

 the kind of spray to be used, the extent of the operations. Get a good 

 pump, one that work easily and smoothly and is strong enough to make 

 a fine spray when two lines of hose and four nozzles are used, if it is 

 designed for field work; it is economy in the end. Look over the agricul- 

 tural papers for advertisements of spraying outfits and write for circulars. 

 Power pumps are becoming more popular each year. 



When Bordeaux mixture is used on fruit trees it will nearly always 

 pay to add an arsenical poison.
