would certainly be destroyed. Grasshoppers, in places, injured 

 apple grafts noticeably. In one nursery spraying was resorted to to 

 kill this pest. Crown Gall, Anthracnose, Rust and Black Rust were 

 in evidence in localities. Two diseases of apple trees hitherto un- 

 known in Minnesota were discovered. One of these was identified 

 by the Division of Plant Pathology — as ConiotJnji iiim fuckdii. 



On foreign stock in 1911 we found no nest of Brown Tail Moth 

 and no egg clusters of Gipsy Moths, but pupal cases and larval 

 skins of the latter insect were present on imported Azaleas, show- 

 ing the necessity for keeping up a rigid inspection of all imported 

 stock.

 sued. The list follows:

Mr. C. C. Hunter and Mr. Emil Sahler were inspected in 1912 

 but have not been granted certificates at date of writing. In 1912 

 the nurseries were found to be for the most part in good condition. 

 Various injurious insects of minor importance were present to 

 some extent, some crown gall on raspberries, anthracnose, blight 

 and rust, but by no means of universal occurence and not strik- 

 ingly abundant.
