Spraying 



Spraying is a vital necessity if money is to be made from fruit. 

 It doesn't pay to miss one season, even if enemies are not visible. 

 Spraying has an invigorating effect on trees, besides controlling 

 enemies. 



There are three classes of enemies spraying will control — 

 chewing insects, sucking insects, and fungi. Each class requires a 

 different remedy, but the remedies can be combined most of the 

 time. 



Spraying during the dormant period is distinctly different from 

 spraying on foliage. Materials several times as strong can be 

 used and are needed to control the scales. 



On account of the life-habits of enemies, often only two to 

 seven days are available for any one spraying. Do the work 

 then. Put the material on with force and cover every inch of 

 bark and leaf. 



Get a sprayer that is big enough, that will give one hundred to 

 two hundred and fifty pounds of air pressure, that is adapted to 

 your land and trees, and that is durable. Get a power outfit, if 

 possible, for it does better work than a hand-pump can. 



The spi'aying programme ordinarily resolves itself into two, 

 three or four applications — one while trees are dormant, with 

 lime-sulphur solution, and the others on blossoms and fruit with 

 self-boiled lime-sulphur, or diluted lime-sulphur, with arsenate of 

 lead added, or maybe with Bordeaux and lead. All applications 

 must be guided by careful study. 



Borers will attack fruit trees in spite of all we can do, and will 

 kill many trees if left alone. Trees must be gone over several 

 times each year, and should be gone over each April and August. 

 Spraying and painting with lime-sulphur sediment will help in 

 keeping down the numbers of borers. 



The table of spraying operations (see preceding page) gives all 

 the information needed to keep your trees in prime condition. 

 The main point is to spray at the RIGHT TIME. (We are in- 

 debted to the Maryland State College of Agriculture for this 

 complete table and formulas.) 



SPRAYING POINTERS 



1. Use a machine of adequate capacity. 



2. If a power sprayer is used, consider weight, type of pump, 



and simplicity of the engine and its gearing to the pump. 



3. Valves should be easily accessible and preferably of the ball 



type. Packing should be easily replaced. 



4. Relief valves should be simple and reliable. 



5. Propeller agitation is the most satisfactory. 



6. Get the best accessories. Cut-offs should be two-way and 



quick in action. 



7. Nozzles should be of the angle type, of large capacity, with 



a minimum number of parts. 



8. Wire-wound hose is cheapest in the end and best for or- 



chard work. 



9. Spray to cover every part of the tree or crop. 



10. Strain your materials thoroughly. 



11. Have adequate water supply, preferably under pressure.
