QUARANTINE LAWS AND ORDERS. 7 



lots, amounting to 236 bushels. The plan works well and to the full 

 protection of the citrus fruit industry as far as it is affected by the 

 importation of orange seed : 



QUARANTINE ORDER NO. 1. 



Citrus White Fly. 

 (Amended April 1, 1910.) 



WHEREAS, Information has been received by the commission to the effect that the 

 White Fly (Aleyrodes citri) is prevalent in the states of Florida and Louisiana, and 

 that it is found upon a wide range of plants and trees in these states, where it is a 

 serious, costly, and uncontrollable pest, and that oranges, lemons, citrus and nursery 

 stock, as well as herbaceous and other plants, are infested with said White Fly 

 (Aleyrodes citri) ; and 



WHEREAS. Said Aleyrodes citri does not exist upon any fruit, trees or plants in the 

 State of California; and 



WHEREAS. There is great danger to be apprehended to the fruit industry of this 

 State from the importation of nursery stock, trees, fruit or plants from infested sec- 

 tions in Florida and Louisiana ; therefore, 



It is declared. That a horticultural quarantine be, and is hereby, established against 

 all fruit, nursery stock, fruit pits, orange seed, and plants of all kinds imported from 

 the state of Florida, Louisiana, or any other sections known to harbor Aleyrodes citri, 

 into the State of California ; all horticultural commissioners, local inspectors, and 

 deputies of the State Horticultural Commission are hereby instructed and required to 

 hold any and all such fruits, nursery stock, fruit pits, orange seed and plants of all 

 kinds, subject to the shippers or owners thereof, for exportation out of the State or 

 to be destroyed ; provided, that orange seed may be received into the State of Cali- 

 fornia upon compliance with the following conditions : 



Every lot of orange seed brought into the State of California from Florida, 

 Louisiana or other territory infested with Aleyrodes citri must be enclosed in a box 

 sufficiently tight and secure to prevent the egress of all insect pests should any be 

 enclosed ; every such lot of seed must be shipped to William Wood, quarantine 

 inspector, or to any other person authorized in writing by the State Commissioner of 

 Horticulture to receive it ; every such lot must be delivered at such freight or express 

 office as shall be designated by said William Wood, or other authorized person, and 

 held by him in quarantine until in his judgment the lot should be released. All 

 expense incurred in treating for disinfection of such lot of seed shall be paid by the 

 consignee or owner, and the seed shall not be released till the same is paid.

State Commissioner of Horticulture. 



Approved by : 



J. X. GILLETT, 



Governor of the State of California. 



Before we leave the consideration of this order a very interesting case 

 is appended concerning its recognition by the United States Govern- 

 ment. The Bureau of Plant Industry at Washington is engaged in 

 plant breeding and selection in Florida, and while the Federal author- 

 ities may have the legal right to ignore our state quarantine law in the 

 distribution of these plants, they did not attempt to violate its provi- 

 sions. Wishing to distribute throughout southern California a large 

 lot of improved avocado and other plants, application for a permit was 

 made and refused by the State Commissioner, who later sent an agree- 

 ment to P. H. Dorsett of the bureau, which would permit the introduc- 

 tion of the plants without possibility of introducing the White Fly. 

 This was signed by Mr. Dorsett : 



IMPORTING FLORIDA STOCK. 

 Agreement. 



(Modifying Quarantine Order No. 1.) 



OFFICE OF STATE COMMISSIONER OF HORTICULTURE,, 



SACRAMENTO, CAL., March 4, 1910. 

 Mr P. H. Dorsett, Bureau of Plant Industry, Washington, D. C. 



The conditions imposed by the State of California upon the introduction of Florida 

 stock are as follows : 



1. The plants to be sent to Washington and there detained in your quarantine 

 greenhouse for a period of six months. 



2. At the end of that time they may be shipped to the horticultural commissioner 

 of the county in California in which they are to be delivered. I will instruct him upon 

 your previous notification of shipments, to receive them and after examination to turn 

 them over safely to the consignee. 



3. Each shipment must be accompanied by a certificate from your entomologist or 

 other authorized official stating that the plants have been in quarantine the required 

 time, and that there are no Aleyrodes citri or other species of citrus white fly in the 

 quarantine greenhouse.
