Arizona republican., 1916-01-23

account of the danger of introducing | citrus canker into the state from the | Gulf Coast states. This quarantine on | January 10, 1916, was amended to in- clude citrus seed and adopted as a i new quarantine order, Number II, l taking the place of the previous citrus ! fruit quarantine which was numbered ! 10. Quarantine Order Number II, | which is now in effect reads as fol- 1 lows:
 Citrus Fruit and Seed Quarantine 1
 In order to prevent the introduc- tion of the disease known as citrus canker into the State of Arizona, it is hereby ordered and declared:
 (a) That hereafter the importatio
 into the state of Arizona of all citrus
 fruits and citrus seed grown in or
 shipped from Georgia, Florida and' all
 other states bordering on the Gulf of
 Mexico is prohibited, except that the
 use of grapefruit in dining cars on
 pecially authorized by the commission. (b) That all persons. firms or cor porations in the state of Arizona are prohibited from having possession of transporting, selling or giving away any of the fruit or seed hereby quar- antined against except when espec- ially authorized by the commission as above
 Co That Quarantine Order No. 10 is hereby rescinded.
 In addition to the foregoing quar-
 antine orders the commission adopted
 Mexican Orange Maggot Quarantine
 on September 3, 1912. This prohibited the importation of oranges guavas and mangoes grown in the Republic | of Mexico Soon after being placed in effect the responsibility for pro tection against the Mexican orange maggot was assumed by the Fedora Horticultural Board which adopted a quarantine and provides an inspection | service for the protection not only of 1 Arizona but of all citrus fruit growing states against the Mexican orange maggot A more recent quarantine of | the Federal Horticultural Board pro hibts the importation into this cOun- | try of all citrus stock grown in for 1 eign countries.
 I 1 California into the state of Arizona 1 but in. citrus fruit growing sections it I is subject to inspection and when | found infested with citrus scales such | fruit shipments are condemned or 1t | is required that they be disposed of | in some section of the state where no | citrus fruits are grown.
 | AriZona's s citrus growing sections | are at present better protected against l the importation of diseases and pests l than is any other citrus growing state
 or district in the country. Neverthe l less as indicated in your paper in the articles referred to citrus pests can | be carried by other plants than those | specifically quarantined against. This has already occurred in this state. The | cottony cushion scale has been intro duced into Bisbee, Arizona, on Orna mentals, the ivy scale has been intro 1 duced into Tucson and Phoenix on oleander and English ivy, the Califor- 1 nia Red Scale has been introduced l into Phoenix on rose bushes and the l soft brown scale has been introduced l into the Salt River valley, probably l on oleanders and other plants. All of these insects are pests of citrus, | the red scale being the most destruc- tive citrus scale pest in California.
 These importations all took place be- fore Arizona had any provisions for the inspection of infested plants. The red scale was discovered and eradi- cated before it had spread from the rose bushes upon which it had been ijmpOrted from California. An account of this with photographs of sections of the infested rose bushes was pub lished in the writer's annual report
 for the year ending June 30. 1912 | The soft brown scale is not an in 1 sect of great importance as a citrus
 pest. It is so widely distributed in Arizona that an eradication with our
 present resources at least is impracti-
 cable. The ivy scale attacks olives as , well as citrus fruit trees. It is be-
 lieved that this scale is not scat I tered too widely to be eradicated ir l the Salt River Valley and the at
