162 SIXTEENTH BIENNIAL REPORT 



THE STKAWBERRY ROOT BOREB 



(Sesia rutilans Hj'. Edw.) 



This root borer is a serious pest of the strawberry, occurring in the State of 

 Oregon nearly everywliere the strawberry is grown. Tbie elongate white larva, 

 with brown head and darker biting jaws, feeds on the iuterior of the crown and 

 tap root of the strawberry plant, eating out the eutire heart. The plant, as a 

 result, looks sickly and, when pulled up, will offen break just below the crown, 

 exposing the tunnel filled with frass and excrement, and offen the larva itself. 

 The adult insects are clear-winged moths. 



Remedial Measures 



Dig up and destroy infested plants, preferably in late fall or early spring. 



STRAWBERRY CILTURE EXTENDS THROUGH STATE 



Oregon Growers Produced Five Per Cent of Total Tonnage in America During 



1919, for Which They Received $1,000,000, ffighest 



Retunis Ever Recorded Here 



By W. H. Walton, Editor Better Fruit 



Of the bush fruits, the strawberry, uutil the last year, was the largest income 

 producer in Oregon, but the heavy planting of loganberries has now pushed it 

 back into second place. The fame of Oregon as a strawberry-produciug state has 

 largely rested on the Clark seedliug, produced so extensively in the Hood River 

 Valley and, to some exteut, in other sections of the State. This berry, which has 

 no superior as a shipper, has been sold successfully all over the Middle West 

 when marketiug conditioiis made it necessary and has widely advertised Oregon 

 and its strawberries. 



From now on, however. the reputation of Oregon as a strawberry-produciug 

 State will not be confined to the limited area in the Hood River Valley, as the 

 erection of canning and processing plants throughout the State is causing ex- 

 tensive plautings in Western Oregon, and thousands of pounds of this fruit, 

 ciinned and put up in the form of jams and jellies, will be shipped to all parts 

 of the World. 



In 1919, Oregon produced about five per cent of the total tonnage of strawber- 

 ries grown in the United States, for which the growers received in the neighbor- 

 hood of $1,000,000. Of this amount, the Hood River district, which shipped over 

 100 cars, received $300.000 ; in fact, the net returns to the growers this year 

 were the highest ever known in the history of the industry. The other large 

 producing districts were Western and Southern Oregon and those pai-ts of Eastern 

 Oregon where there is Irrigation or the rainfall is not too light to prevent the 

 fruit from maturing. 



While great success has been achieved in producing strawberries in the Hood 

 River district, the big development in this industry in the future will be in the 

 Willamette Valley and other sections of Western Oregon, where the soll and 

 climate are particularly adapted to the propagation of this berry, and where 

 fixed markets have been made for it by establishing cannei-ies at most of the 

 central points in this territory, such as Salem, Albany, Roseburg and Eugene. 



Growing Area Extends 



In fact, the creation of cooperative marketing Organization« and the erection 

 of processing plants, coupled with profitable returns, is stimulating the bush fruit 

 industry to such an extent that Clatsop. Coos and other counties in the western 

 and southern parts of the state, that heretofore have grown a limited quantity of
