Nursery Inspection. 



Complying with the law concerning the inspection of nur- 

 series, or other places where plants are grown and offered for 

 sale, the various nurseries in the state were visited as usual and 

 the condition noted. 



Practically all of the nurseries listed in last year's report were 

 visited and some additional ones were added to the number 

 during the past season. San Jose scale, woolly aphis, rose scale 

 and gypsy moths were the principal cause for withholding the 

 certificates. In all of the cases referred to, the owners were 

 able to control the various pests by careful spraying and removal 

 of badly infested specimens. 



Several nurseries were inspected without a request being 

 made by the owner and in a few instances the stock was in such 

 a neglected condition that no certificate was issued, pending a 

 definite request from the owner. 



The records show that various plant pests were discovered 

 and that definite steps for control were taken immediately. The 

 pests which were reported are listed below and all nurserymen 

 are cautioned to watch for their presence that control may be 

 made at once. 



Crown gall on brambles. 



Orange rust on blackberries. 



Oyster-shell scale. 



Chermes gall on spruce. 



Pine tip borer. 



Aphis of various sorts. 



Currant worms. 



Rose stock borer.

A list of the certified nurseries is included in this report, as 

 may be noted.
