CONCERNING NURSERY
 STOCK NEGOTIATIONS
Circular Issued By A. w. Merrill, Entomologist of Horticultural
 Commission

| the entomologist of the Horticultural commission, and forwarded as nearly as practicable to all directly concern ed The importance of it and the authority for the action are both set forth in the letter itself:
 Dear Sir-At a meeting of the Ari- zona Horticultural commission on No- vember II. 1909. the following reso- ution was adopted;
 For the protection of the buyers of nursery stock and ornamental plants to be shipped into the Terri tory of Arizona by nurserymen and dealers in other states or territories, or in foreign countries: and in order ! to avoid unnecessary losses to such nurserymen or dealers it is hereby ordered by the Arizona Horticultural commission. that through the ento- mologist of the commission, buyers, nurserymen and dealers concerned as . far as may be practicable be advised that all nursery stock or ornamental plants for shipment to points in Ari- zona should be purchased subject to being found uninfested with injurious insects upon inspection by the ento- mologist or district inspectors of the commission; also that certificates of release will be granted only when the plants inspected are found ab-
 Solutely free from insect pests; also
 that shippers of plants of any and all kinds into the Territory of Ari-
 Zona be advised to carefully examine the provisions of the act for the pro
 lection of the horticultural interests of the Territory of Arizona, being 1 Chapter 90, Laws Of l909'
 A copy of the first annual report of the Arizona Horticultural com mission is sent to you under separate cover. This report contains the full text of the law referred to above. Your attention is called particularly | to the provisions of sections F and l3. l |. In regard to the defoliation of trees and shrubs shipped into Arizona, the | following resolution was adopted:
 In order to permit tine most ef- | ficient inspection service. it is here by ordered that previous to shipment into the Territory of Arizona, the following plants be defoiiated: All deciduous trees and shrubs, cape jes- samine. privets, olive and pepper
 trees. All such of the plants here included when not completely defol- lated are hereby quarantined against" It will be noted that the defoliation of citrus trees is not required. All shippers should bear in mind that the chances of infestation Toy numerous pests are greatly reduced by defolia- tion and, except in cases of absolute confidence in tine freedom of the trees or plants from insect pests, de- foliation should be practiced as a matter of elfprotection. Oscillation of citrus stock originating in sections known to be infested by white flies has been practiced by shippers in the past, and a rule which has been proposed for the adoption by the commission at some future time. re- quiring defoliation in such cases. will not, therefore, affect ordinary shipments.
 Shippers should avoid shipping into Arizona any trees. shrubs or, plants of any kind. concerning which there is doubt in regard to their freedom from insect pests. F'umigation of in fested plants or dipping them in or scrubbing them with insecticides, such as whale oil soap. will not be regarded as rendering the plants un- infested, provided that insect pests are attached thereto. Neither fumi- gation nor the use of washes can be relied upon to accomplish absolute extermination. In fact extermina- tion is rarely accomplished by either method, and if insect pests are found attached to plants. it is to be pre- stunned that live insects are present as well as dead ones.
 Shipments from all sections will re- ceive equal consideration as far as thel inspectors in Arizona are con cerned While except as heretofore noted. no quarantines have been es- tablished by the commission. defin ite danger has been recognized in shipments of nursery stock and food plants of certain insect pests from districts known to be infested. This applies, in T degree, as has been explained. to nursery stock or other plants, regardless of any treatment to destroy the infesting species of in- sects. Inspections, therefore will be most thorough since the situation de- mands the full protection afforded by the law.
 To all nurserymen who are plan ming to make large shipments of plants of any kind into the Terri tory of Arizona, and who desire to have assurance that their stock will pass inspection. it is recommended that a small sample shipment be sent to their agents, consigned to one of the following points: Saf- ford or Thatcher. in Graham county; Mesa, Tempe or Phoenix in Maricopa county. In case such test shipment is made please notify the under signed as to whom shipment is be- ing consigned and as to whether shipment is being made by freight or express.
 Yours truly.
