The ideal spray is a fine mist, and the best worlv is done when the 

 plant is thoroughly and evenly covered Avith line drops. Stop spray- 

 ing before the foliage is drenched. 



The higher the pressure, the better the spray. 



Clean all sprayers each time after using. 



For delicate foliage, spray after this gets under shade. Hot sun- 

 light is dangerous with many sprays, such as kerosene emulsion. 



SPRAYING AND DUSTING APPLIANCES. 



P The materials recommended herein may be applied in various w^ays. 



For the small garden an atomizer sprayer, such as is shown in 

 figure 5, is good, but a better sprayer for gardens of small and 

 medium size is illustrated in figure 6 and on the title-page. In 

 the case of the atomizer 

 sprayer it is an advantage 

 to have the container for 

 the liquid made of glass,, 

 as Bordeaux mixture and 

 other materials attack tin 

 and iron. These sprayers 

 cost from 50 to 75 cents. 

 A similar but more durable 

 and effective sprayer made 

 of brass costs $1.25. 



Compressed-air sprayers 

 may be had in galvanized 

 steel at $3.50 to $5, and in 

 brass at $6.50 to $12.50. 

 Bucket spraA'ers such as the 

 one shown in figure 7 range 

 in price from $2.25 to $5. 

 To do good work with 

 them, however, tw^o persons 

 are required. 



Really efficient sprayers 

 are expensive, but if w^ell 

 cared for will last many 

 ,vears. Neighborhood co- 

 , operation may solve this 

 problem. If a number of 

 garden owners club to- 

 gether to purchase a 

 spraj^er, it is advised that 

 a barrel pump on a hand 



cart be secured, or the bar- Fig. G.— Comin-cssed-aii- sprayer.
