Strawberry Root Weevil 



Within the past month tlie State of California has placed lipon us a quaran- 

 tine regulation concerning the strawberry root weevil. An iuvestigation disclosed 

 the fact that this pest exists in the Northei*n part of our State. To consider 

 this matter, a pulilic meeting was called at Fortland on December 17. There 

 were about fifty strawberry iJlaut growers present to meet Mr. Lee A. Stroug, 

 a representative of the California Quarantine Department. The subject was 

 carefully considered with the result that a survey of the State will be made to 

 ascertain the extent of the distribution of the strawberry root wee^•il and that 

 no plants will be allowed to be shipped or sold from any strawberry plantings 

 in the State where there is any doubt about the same being free from the weevil. 

 This regulation will not only apply to our shipments to California, but will 

 apply to any other shipments of strawberry plants. 



Potato Tuber Moth Quarantine 



A public hearing to consider a quarantine regulation covering the movement 

 of potatoes from California to Oregon was held in Salem, on December 14. 

 There were present at this meeting the following representatives : Department 

 of Agriculture of California, Potato Shippers of San Francisco, Commission 

 Merchants of Portland, Members of Oregon State Board of Horticulture, and 

 many local potato growers. Everyliody present was given an opportunity to 

 diseuss the subject, after which the matter was taken uuder advisement until 

 the details of a quarantine regulation can be considered by the proper represen- 

 tatives of the Western Plant Quarantine Board, as what will apply to Oregon 

 will probably apply to the other AVestern States. The purpose of the quarantine 

 will be to prevent the shipment of such potatoes from California that carry 

 the potato tuber moth in any stage of development. If there are portions of 

 California that are free from the tuber moth, we will try to arrauge that 

 potatoes from such territory can be shipped under due care and caution. We 

 feel sure that when potatoes have been subjected to the fumes of bisulphide of 

 carbon in a vacuum fumigator that the tuber moth in any stage of development 

 is killed, so potatoes that have been thus treated should be allowed to come into 

 Oregon. We will work out the details covering these conditions before any 

 potatoes are shipped from California into Oregon. 



By our quarantine measures we are endeavoring to confine the plant pests 

 and diseases to areas already infested and thus hold back and retard the 

 advance to new fiekls, while control methods can be put into Operation.

REPORT OF HOMER C. ATWTLL, COIVIMISSIONER OF THE 



FIRST DISTRICT 



To the Honorable State Board of Horticulture: 



The past year will long be remembered by Oregon horticulturists for the 

 excessively cold snap of December last, said to have been the coldest weather 

 the State has experienced in fort}' years. Had it not been for the deep snow 

 that lay on the ground, during the severe weather ; and the fact that, at that 

 time of the year, trees are usually more nearly dormant than during any other 

 part of the year, the results would have lieen disastrous. As it was, great 

 damage was done on the lower levels, not only to fruit trees but to deciduous 

 forest trees as well. The unprecedented severity of the freeze is iudicated by 

 the fact that native oak trees, supposed to be over one hundred years old, were
