used in the propagation of nursery stock. This course has been 

 successfully adopted by some of the larger growers in this state. 

 Very few nursery trees have been reported destroyed because of 

 black knot, blight, canker or galls on the roots produced by either 

 fungi or insects. The primary and principal necessity of nursery 

 inspection is caused by San Jose scale and our efforts are directed 

 toward preventing its further distribution in nursery stock. 



There have been issued 535 certificates of inspection, of which 

 444 were to regular nurserymen; 65 special certificates to berry 

 growers and others and 26 for- the inspection of vineyards where 

 the wood is used for propagating. There were 605 duplicate cer- 

 tificates of inspection issued to nurserymen for filing in other 

 states. Seventy-one notices of fumigation were served upon 

 nurserymen of this state. One hundred special certificates were 

 issued on individual shipments. 



The following table shows the quantity and kind of nursery 

 stock in the nurseries of the state as reported by the inspectors at
