LOUISIANA CIRCULAR No. 4. 



treated in this manner the trunk itself should receive a thorough 

 coating. As the operator sprays, it is necessary for him to mo\v 

 around the tree so as to coat each limb and twig upon all 

 sides. While it may appear to the reader that to spray a tree 

 in this thorough manner would require considerable time, as a 

 matter of fact, one who is accustomed to "handling the no/xle" 

 will spray an ordinary sized peach tree in from one to two min- 

 utes. Spraying in a strong wind cannot be done satisfactorily, 

 but where there is only a light breeze the operator will soon 

 learn that by commencing with the nozzle directed against the 

 wind, but at an angle to it, he can move around the tree and 

 reach every side of it without being compelled at any time In 

 get directly upon the leeward side of the tree where the spray 

 will be blown upon him. 



The lime-sulphur, in order to be an effective agent agains! 

 the scale-insect and to penetrate the scale-covering, must <i 

 necessity be strong and corrosive in its action and if the opera 

 tor's face and hands are continually wet with it they will become 

 sore. For this reason the operator must guard against the spra\ 

 being blown into his face, or if careless, should protect his face 

 with a mask of heavy cloth. The fittings of the hose and nozzle 

 should be kept tight so that the liquid will not be continually 

 leaking out ,?nd getting upon the hands of the operator. A pair 

 of cheap leather gloves forms an effective protection for the 

 hands. 



After the first application has dried upon the trees, the lat- 

 ter appear as if covered with a coating of white lead, and all 

 spots that have been missed in the spraying are easily seen. The 

 orchard should now be gone over again the second time and all 

 of these unsprayed spots properly coated with the wash. 



In the choice of spray pumps the orchardist has a wide vari- 

 ety from which to choose, and the pump decided upon for the 

 work should be dependent largely upon the number of trees to 

 be treated. A cheap, flimsy affair of tin or copper, such as ii 

 used by many gardeners, cannot be used for the application of 

 the lime-sulphur, for, in the first place, copper is entirely cor- 

 roded and eaten up in a short time by this mixture, and, in t 

 second place, these cheap pumps are so constructed that the
