IV. TO PREVENT OR DECREASE DISEASES OF PLANTS 

 i. BORDEAUX MIXTURE 



Bluestone (copper sulfate), 5 pounds. 

 Best unslacked lime, about 5 pounds. 

 Water, 50 gallons. 



Slack the lime with enough water to make a creamy wash. Add the 

 lime and the bluestone to separate lots of water. Dilute each as much 

 as convenient before pouring the two liquids together. Strain through 

 a coarse cloth before using. Consult your experiment station regarding 

 further details about mixing and testing Bordeaux mixture, etc. When 

 applied to the foliage of peaches, plums, or cherries, double the amount 

 of water mentioned above. 



Apply Bordeaux mixture in a fine spray. It is used to prevent or 

 decrease molds and most fungi attacking fruit trees and vegetables. 

 Paris green can be added just before using the mixture, pound of Paris 

 green to 50 gallons, thus destroying both fungi and leaf-eating insects 

 at the same time. 



2. FORMALIN 



To prevent oat smut, concealed smut of wheat, scab and other diseases of Irish 

 potatoes. 



For wheat or oats, pour one ounce of formalin into three gallons of 

 water. Dip or thoroughly moisten the seed-grain, and leave it moist 

 and covered for two hours. Then dry the grain, and sow it before it 

 comes in contact with more smut germs. 



To prevent scab, soak the seed-potatoes for two hours in a solution 

 of I ounce of formalin in 2 gallons of water. 



V. TO MEASURE GRAIN APPROXIMATELY 



Multiply the average depth by the average width, and the product 

 by the average length of the pile, crib, or bin. To get the number 

 of bushels of shelled grain, divide this figure (number of cubic feet) by 

 i; to find the number of "bushels" of shucked ear corn, divide by 

 2\ ; to find the numbei of " bushels " of unshucked ear corn, divide 

 by 4.
