666 THE MONTHLY BULLETIN. 



spread is usually through the transportation of infested potatoes, all 

 growers and shippers in the infested areas of this State should take 

 every precaution to see that not a single infested potato is allowed to 

 be shipped either to points within or without the State. It is feared 

 that if our growers do not heed this, that it will not be long before 

 some states take action to prevent the shipping of all California 

 potatoes, which will mean a great loss to commercial potato growers. 



For the protection of the potato growing industry of California, 

 growers should procure seed potatoes from districts known to be 

 entirely free from this pest. All seed should be thoroughly inspected 

 just before planting to be sure that obscure infestations have not 

 developed in storage. 



It is sincerely hoped that all public horticultural officials, growers 

 and shippers will work to the end that no infested potatoes be allowed 

 to be shipped or planted. — E. 0. Essig.
