SIXTEENTH BIENNIAL REPORT 



As President of tlie Oregon State Board of Hortieulture and Quarantine 

 Officer. I liave to report that tlie Western Plant Quarantine Board was organized 

 at Riverside, California, in May, 1919, with a membership composed of the plant 

 quarantine officers of the eleven AVestern states, the territory of Hawaii, the 

 province of British Columbia, and the Northern district of Lower California. 



The purpose of the Organization is to protect the Western states, provinces 

 and territories as a whole against the introduction of plant pests and diseases 

 not estal)lished West of the Rocky Mountains by promoting uniformity of action 

 in the Promulgation and enforcement of plant quarantine re.gulations and to 

 Protect each other through close association enabling a better undei'standing 

 of the quarantine problems in each state. The officers of the Board are: Mr. 

 G. H. Hecke, Director of Agriculture of California, Chairman ; Mr. Chas. A. 

 Park, President of State Board of Hortieulture of Oregon, Vice-Chairman ; and 

 Mr. Harold R. Hagen, State Inspector of Crops and Pest Commission of Utah, 

 Secretary. All of whom were elected for a period of two years. 



The first annual meeting of the Board was held at Salt Lake City, Utah, 

 in May, 1920, with all of the members present except the territory of Hawaii. 

 Thiii; meeting was marked I\v much enthusiasm and liarmony. The personal 

 acquaintance and touch made possible by these meetings is doing much to solve 

 our Problems efficiently and harmoniously. 



Alfalfa Weevil Quarantine 



We have modified our Alfalfa Weevil quarantine against Idaho so as to 

 include the whole State of Idaho and a small portion of the Eastern part of 

 Malheur County which borders on Idaho. At this point the alfalfa weevil have 

 secured a lodgment by being carried across the Snake River into Oregon. We 

 hope to delay and retard the progress of this dreaded pest so that with control 

 methods its damage may be reduced to a minimum. The quarantine withholds 

 much hay from the market and results in serious loss to the growers. To 

 render the hay and its products safe for transportation to clean fields is a 

 Problem confronting the Board. The manufacture of alfalfa meal from the hay 

 promises to help solve the problem to a certain extent. It appears that it is 

 doubtful if any weevil in any stage of development can survive the milling 

 process, but much care must be used to prevent the product from becoming 

 infested after being milled. Under proper precautions we hope to be able to 

 move alfalfa meal. 



Another means of moving this hay would be to submit it to vacuum fumiga- 

 tion, using the bisulphide of carbon as the fumigate. By this metliod it is 

 possible to kill the weevils in the product after it is packed and ready for 

 delivery to the buyer. If the cost of this method of fumigation is not prohibitive 

 it will offer an efficient way of handling the infested hay. I hope that a plant 

 of sufficient capacity may be established at some convenient point.
