States Entomological Commission, together with a statement 

 of Prof. C. V. Riley, entomologist of the United States 

 Department of Agricullure, are appended as samples of the 

 opinions and experience of the most reputable scientists and 

 ex})eriment station directors of this country. 



* " The destruction of our fruits to so large an extent for 

 the past few years by fungous pests and insects shows us 

 the necessity of using every remedy that we know of 

 for the destruction of the causes of this loss. 



" The many letters received at this Station asking for speci- 

 fic instructions relating to the use of the best known fungi- 

 cides and insecticides have led to the issue of this bulletin. 



" Our information is based upon the experiments made at 

 this Station, those of the Department of Agriculture at 

 Washington, the work of many other stations of the country, 

 and the practice of the large orchardists and vineyardists of 

 the country, who have made successful use of the remedies. 



" The time which experiments have been carried on in this 

 line has not been sufficient to decide in every case and under 

 aU conditions, what may be the most economical and the 

 safest remedy or mode of application, but enough has been 

 learned to warrant the recommendation of the use of a few 

 of the best known remedies, and we feel confident that if the 

 directions are carefully followed and no unusual conditions 

 present themselves, great benefit may be derived from their 

 use. 



Treatuient for the Aijple. 



1. As soon as the petals have fallen, spray with the 

 Bordeaux f mixture and Paris green, one pound to two hun- 

 dred gallons of the mixture, for the insects and apple scab. 



2. Apply the same mixture again in eight or ten days. 

 Should it have rained hard within a few days of either 

 spraying, another application must be made at once. 



3. In about two weeks spray again with the same mixture.

 Station of the Massachusetts Agricultural College. 



t BoHDEAUx MixTVRE (Foran/7a) . — Dissolve six pounds copper sulphate in 

 two or three gallons of hot water. (If in a powdered form it will dissolve readily in 

 cold water.) Slake four pounds of fresh caustic lime in water enough to make a thin 

 whitewash. When both are cool, pour the two mixtures together, stirring thoroughly, 

 then add water enough to make twenty-five gallons of the mixture. Strain through 

 a line wire or cloth strainer before using.
