HOW TO GROW AND MARKET FRUIT 



is to it. The tree will live and the bark will grow over the 

 wounds. 



SUMMARY 



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

 fruit. It doesn't pay to doubt this, and it doesn't pay to miss 

 one season, even if enemies are not visible. 



Spraying has an invigorating effect on trees, besides con- 

 trolling enemies. 



Knowledge of what to spray for, what mixtures to use and 

 when to apply is a necessity before spraying can be made effec- 

 tive. 



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 life habits of enemies, often only two to four 

 days are available for any one spraying and the work must be 

 done 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 100 to 250 

 pounds 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 spraying program 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. 



The differences in spraying mixtures is one of chemical 

 combining of the materials, as well as of differences in quantity 

 of each material used. Be sure you get the right mixture. 



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 once 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. 



Keep trash and mulches at least six inches away from tree 

 trunks, and tramp snow about trees in late winter, to prevent 

 mice damage. 



Always bridge-graft trees that have been girdled.
