COMPOUND SOLUTION OF CRESOL. 



For sterilizing knives, saws, shears and other tools, nothing is better 

 than compound solution of cresol used at the rate of from two or five 

 per cent in water. It has the advantage that it helps cleanse the tools 

 and softens dirt that might otherwise cling to them. It is useful for 

 cleansing and sterilizing tools used in pruning where diseases are pres- 

 ent, and for sterilizing the knife used in cutting out peach-borers, in 

 order to avoid distributing crown-gall through the orchard. 



rOISONED SYRUP FOR ONION MAGGOT. 



Dissolve five grams or 14 ounce of sodium arsenate in one gallon of 

 hot water and add half a pint of New Orleans molasses. Distribute a 

 small amount of tl^is in small basins covered with wire screen of just 

 small enough mesh to keep out bees, using 15 or 20 of these basins to the 

 acre, and put the pans in position just as the onions begin to nicely get 

 through the ground, keeping them replenished until the danger is past. 

 The efficiency of this bait is increased if a slice of onion is added to the 

 syrup in each pan. 



Two tablespoonsful of the stock solution of Kedzie-mixture will take 

 the place of the five grams of arsenate of soda. 



Cautions. 



Do not spray while plants are in bloom. It is prohibited by law, 

 except when canker-worm is present, and may destroy bees and other 

 beneficial insects. 



Do not dissolve copper-sulphate in an iron or tin vessel. It will 

 ruin the vessel and spoil the spraying solution. 



For all spraying solutions containing copper-sulphate, the pump 

 must be brass or porcelain lined. 



Wash out pump and entire outfit each time after using. 



Use arsenate of lead with lime on stone fruits in preference to other 

 forms of arsenical poisons. It is less liable to burn the foliage. 



Do not spray fruits or plants with poison within a month of the 

 time they are to be picked. 



Keep all ''stock solutions" covered to prevent evaporation, and oxi- 

 dation. If a "spray gun" is used try to do the work when the mixture 

 will dry on the tree quickly. 



Do not use lime-sulphur solution as a summer spray for grapes, 

 potatoes or tomatoes. 



Do not use Paris-green or Kedzie-mixture in combination with lime- 

 sulphur sprays.
