100 OECHAKD MANAGEMENT 



More detailed information 1 can be had for these and other 

 ■depredations, not named, by sending to this station. By send- 

 ing specimen of injuries it helps to identify them. 



Borers : All tree fruits are affected with borers. The best 

 remedy is to go over and examine the base of the trees in 

 spring and fall, and dig them out, if present. Do not let them 

 get established. 



Apple Maggot (Railroad Worm): Keep pigs or other stock 

 in the orchard so as to eat the fallen fruit. 



Fire Blight : Cut oft' and burn at once all affected limbs. 



Black Aliot : Cut off and burn knots as soon as they appear. 

 Spray with Bordeaux. 



Orange Bust : Dig out and burn affected raspberry and 

 blackberry bushes at once. 



Directions for Making the Bordeaux Mixture, and Princi- 

 pal Insecticides. 



The Bordeaux mixture is the principal fungicide. Its use 

 will prevent scab, rot, mildew, and other plant diseases. Its 

 regular application will insure a healthy, vigorous plant growth 

 and will produce more and better fruit. See Spraying Calendar 

 above for time of ajDplication. 



Formula for Making: Copper sulphate, six pounds; fresh 

 lime, four pounds; water to make fifty gallons. 



Fill a barrel about one-half full of water. Place the copper 

 sulphate in a coarse cheese-cloth bag, and suspend in the water 

 near the surface, where it will dissolve in a short time. In 

 another barrel place unslaked lime and add a small amount of 

 water. As the lime becomes slaked, add more water from time 

 to time and stir well. Then add the copper sulphate solution to 

 the lime water, and the mixture is ready for use. Do not pour 

 the lime water into the copper solution, but the latter into the 

 former. Strain the lime water before using. Never use the 

 lime water while hot. When spraying on a large scale, slake 

 a quantity of lime, as it will keep indefinitely under water. 

 Dissolve the copper sulphate as directed, and add sufficient 

 lime water for each barrel of mixture as prepared. To deter- 

 mine when enough lime water has been added, use a few drops 

 of Ferrocyanide Test. If it quickly changes color, add more
