August, '141 MORRILL: STANDARDIZATION INSPECTION CERTIFICATES 347 



by even a majority of tlie states, uotwithstandiug its desirability, we recommend, 

 as a much needed reform of nursery inspection practices, the abandonment as soon 

 as possible, of those features of nursery certification which are self-condemned by 

 the assembling of the facts as presented in this report. 



3. We recommend more especially against the use of words in the certificates 

 which necessitate mental reservations of any kind; if a limited number of pests are 

 exclusively referred to by the inspector, such lists should accompany each certifi- 

 cate as a part thereof ; if such pests as may be considered as dangerously injurious 

 in the state without regard for outside sections are exclusively referred to by the 

 certificate, such should be plainly indicated in the certificate. 



4. We recommend that wdiere local conditions require a special form of certificate 

 for the sale and shipment of nursery stock wholly within the state, full considera- 

 tion be given to a wording and style of certificate appropriate for the interstate 

 shipments. In this connection we call attention especially to the styles of certifi- 

 cates now in use in Florida. 



5. We recommend that insect pests and diseases which affect the roots of nursery 

 stock and which cannot be observed by the inspector until the trees are dug, be 

 plainly omitterl from the certification, except where tree by tree inspections are 

 made after the trees are removed from the ground. 



6. We recommend that where lack of suflicient financial support prevents thor- 

 ough inspection of the roots of nursery stock after the trees are dug, that such 

 certificates or licenses as are provided the nurserymen be granted under strict 

 written agreements concerning the separation and destruction of diseased or insect- 

 infested trees at the time the trees are removed from the nursery rows. We call 

 attention here to the system used in Illinois and in Arkansas. 



7. We recommend as a condition for the issuance of a certificate covering nur- 

 sery stock standing in the nursery, that the owner of the trees agree to eliminate 

 as far as possible all crown-gall-infected trees and all stone-fruit trees infested or 

 injured by peach borer and trees of any kind infested with nematodes, and that 

 the shipments upon which certificates are used be guaranteed to be free from 

 visible infection or infestation to the extent of 95 per cent. 



8. We recommend for the consideration of this section the following form of 

 certificate as the basis for the adoption of a uniformly phrased general certificate 

 covering interstate shipments: 



This is to certify that the nursery stock of consisting of 



acres located at ■ — — — — • has been inspected by the under- 



signed or his representative, that the said has agreed to 



comply with regular requirements for the elimination of infested or diseased trees 

 or plants as a condition of the issuance of this certificate, and is hereby authorized 

 to use this certificate or a copy thereof on interstate shipments of the stock speci- 

 fied until unless revoked for cause. It is further under- 

 stood and agreed that neither this certificate nor a copy thereof shall be used to 

 attach to a package or parcel of trees or other living plants to be shipped by mail 

 into states where provisions have been made for the inspection of imported trees 

 or plants at destination. 



Signed . 



I hereby certify that all provisions have been agreed to and the terms complied 

 with in every detail. 



Signed .
