Sprayers 



Clean Relief Valve 



The relief valve which regulates the pressure should be examined, 

 since, if this fails to work, the hose connections are very apt to be blown 

 off. 



Neckyoke and Eveners 



Most beets are planted 18 or 20 inches apart or 16 and 24 inches. 

 In either case three rows of beets should be between the wheels and the 

 wheels 60 inches apart. The eveners and neckyoke should be 60 inches 

 long, so that the horses walk in front of the wheels. Less damage will 

 be done to the crop from broken leaves and crushed crowns if your 

 machine is equipped in this way. 



Setting the Nozzles 



The nozzles should be so placed as to make it possible to spray thor- 

 oughly all surface between the end nozzles. There are so many styles of 

 nozzle equipments and frames that it would require too much space to 

 explain in detail the setting of all. Let it be sufficient to say that four 

 single nozzles should not cover more than 5 rows of beets and 6 single 

 nozzles 7 rows. If the double nozzles are used, 4 pairs will cover 8 rows 

 and 6 pairs 12 rows. In spraying very small beets the nozzles should 

 be placed directly over the rows. 



Testing the Pump 



Before attempting to do any spraying, test the spray pump thor- 

 oughly. The pressure regulates the kind of spray your machine throws 

 (fine or coarse), also the amount of water applied to an acre of ground. 

 Eighty pounds pressure produces the fine mist-like spray required 

 for best results. 



Test Your Sprayer 



It is the poison applied to an acre of beets and not the water which 

 kills the worms. Quick and satisfactory results are secured by the use 

 of 4 pounds of Paris green per acre. Unless you know how much water 

 your sprayer applies to an acre, you cannot know how much poison to 

 use in a tank of water. For example, if a sprayer equipped with 4 double 

 nozzles and producing a pressure of 80 pounds will cover an acre with 50 

 gallons of water, you should mix 4 pounds of Paris green with 50 gallons 

 of water. If the pressure falls very much below 80 pounds, less water 

 will be applied to an acre and more Paris green will have to be added to a 

 50-gallon tank of water. 



To test your sprayer fill the tank with water, put the pump in gear, 

 then drive along the road and measure the distance traveled in discharg- 

 ing all of the water through the nozzles. Multiply this distance, meas- 

 ured in feet, by the width of the number of beet rows you spray; say 5 

 twenty-inch rows or 8.3 feet, and divide this by 43,560, which is the 

 number of square feet in an acre. This will give you the part of an acre 

 you spray with one tank of water. Many failures in spraying are due 

 to using too little poison, and much loss in money results from using too 

 much. Avoid this by testing your machine. From the above you can 

 determine the amount of Paris green to use with a tank of water to 

 apply the 4 pounds per acre.
