 specimens of apples were found, but unless controlled a few years 

 only would be required to infest the whole valley. The State Board 

 this year is going to use every effort to stamp out this isolated in-

 ard or district becomes thoroughly infested. 



Oyster Shell Scale: (Lepidosaphes ulmi Linn.) This is 

 the worst scale insect in the state. It is not of much importance in 

 w^ell cared for orchards, but is present in practically all old and 

 neglected plantings. While it is almost everywhere present it does 

 not spread easily or rapidly from old to well cared for orchards. It 

 can be controlled by thorough and persistent spraying. 



San Jose Scale : (Aspidiotus perniciosti^ Comst. ) This dreaded 

 pest is not present in Montana and it is doubtful if it could endure 

 the climate in the fruit section cf this state.
