Spraying 



large particles getting into it and finding their way 

 to the nozzle. 



Where large trees have to be sprayed long lances 

 may be used to carry the nozzle^d to the desired 

 height. 



Having filled the container and adjusted it upon 

 the back, secured the necessary pressure, turned on 

 the tap so that the mist-like spray is directed 

 towards the plant, see that aU parts of it are covered, 

 the lower leaf-surface as well as the upper, continue 

 spraying just so long as is necessary to effect this, 

 then immediately cease. 



Spray with the wind, but choose, asfar as possible, 

 calm weather for the operation. If rain, especially 

 heavy rain, falls after spraying for fungi and biting 

 insects the operation must be repeated. When 

 spraying with caustic soda (which must never be 

 used on leaves) protect the hands with leather 

 gloves. Spraying is best done in duU weather or in 

 the evening, not in bright sunshine. 



Always cleanse the spraying machine and nozzle 

 after use and put away dry. 



Unless provided with a special nozzle a syringe 

 is a very poor substitute for a spraying machine. It 

 cannot deKver the spray in a sufficiently fine state 

 to do efficient work. 



Where powders such as flowers of sulphur have 

 to be distributed, powder bellows should be used so 

 as to get an even distribution. Little has been said
