Recapitulation of Spraying Directions. 



To recapitulate the spraying directions for the principal mixtures 

 iu use, the following table is presented: 



Paris Green and other Arsen- 

 ites. 



Bordeaux Mixture and combi- 

 nations of Bordeaux Mixture 

 and Paris Green or other Ar- 

 senites. 



Ammoniacal Copper Carbonate. 

 Copper Sulphate Solution. 

 Sulphide of Potash. 



Soap Solutions. 

 Tobacco Water. 

 Caustic Lye Solutions. 



Emulsions. 



Kerosene and Water. 



Crude Petroleum and Water. 



Spray with a fine nozzle under 

 heavy pressure; spray only to 

 the point of covering the fruit 

 or leaves with a continuous 

 coating of fine "dew drops." 



When used for internal fungi, 

 apply as directed for Paris green 

 and Bordeaux mixture. When 

 used against external fungi, use 

 as directed for soap solutions 

 and the like. 



Spray in a direct stream so as 

 to strike with some force, using 

 a coarser nozzle than for Paris 

 green or the like. Avoid exces- 

 sive drip and do not allow the 

 solutions to run down the 

 trunks. 



Spray emulsions as directed 

 for soap solutions, etc. For kero- 

 sene and water and crude petro- 

 leum and water, use a nozzle fine 

 enough to accomplish a thor- 

 ough mixing, but yet capable of 

 projecting the liquid more as a 

 direct stream than as a mist. 

 Completely wet every part, but 

 do not allow^ the mixtures to run 

 down the trunk®, or to accumu- 

 late in forks of branches or in 

 deep wounds.
