70 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



The Bordeaux nozzle is of entirely different structure, the 

 spray being formed by a straight stream hitting a lip which 



breaks it into a fan-shaped spray, the 

 fineness of the spray being governed by 

 the width of the aperture. To unclog 

 the nozzle the core through which the 

 stream emerges is reversed, thus giving 

 a straight stream and clearing the nozzle 

 immediately. For this reason the bor- 

 deaux nozzle is particularly adapted to 



, traction sprayers where several nozzles

for garden and row crops, and some 



prefer it for tree work, though it is not as widely used for that 

 purpose as the previous types. 



The bordeaux nozzle is of great value for applying white- 

 wash, a purpose for which the spray outfit may well be used
