THE NATIONAL NURSERYMAN.

the occurrence of Asp. ancylus, A.forbesi and Chi. furfurus 
would not bar the stock ; the occurrence of any scale insect 
on imported stock would prevent certification, and the presence 
of Diaspis pyricola especially would act as a bar. 
The session then adjourned, to meet as entomologists with 
the Entomological Section of the A. A. A. C. & E. S. at 
2 P. M. 
IN VARIOUS STATES. 
October 7, 1902, 8 P. M. The meeting was again called to 
order by the chairman, and the discussion of Topic 7 con¬ 
tinued. 
Mr. Fernald reported that in Massachusetts no certificate 
would be granted so long as the San Jose scale, Diaspis pencu- 
gona , Asdidictus ostrcefortnis Gypsy Moth, Browntail Moth, 
Yellows, Rosette or Black Knot was found infesting the stock. 
Crown Gall, he stated, had not so far been found in Massa¬ 
chusetts. 
Mr Cossard reported that it was his practice in Florida to 
withhold certificate from the owner of premises infested with 
San Jose scale until the proper steps had been taken to get 
rid of the pest by fumigation or otherwise. Diaspis pentagon 
occurred in the state, but so far had not been found in the 
nurseries. Citrus plants were commonly infested with various 
scale insects, but no definite action had yet been taken with 
respect to such cases. White-fly was so generally distributed 
as to render restrictive measures against it impractical, but 
treatment was recommended. In cases of Crown Gall the 
owners were instructed to destrow all affected plants, and Root- 
knot infestation was also rejected. 
Mr. Hamilton stated that the prevailing rule in Pennsylvania 
was to grant a certificate when the nursery was found appar¬ 
ently free from San Jose scale, and to withhold the certificate 
when this pest occurred. Mr. Butz of the same state explained 
further, that in cases of Crown Gall, Woolly Aphis and some 
others of the more injurious pests, the nurserymen were re¬ 
quested to discard badly affected stock. 
Mr. Burgess reported that in Ohio the presence in a nur¬ 
sery of the San Jose scale, Black Knot or Peach Yellows was 
sufficient ground for withholding certificate, and that plants 
infested with Woolly Aphis or affected with Crown Gall were 
caused to be destroyed He stated that the Oyster-shell Bark 
Louse was doing considerable damage in Ohio, and so far as 
possible its dissemination on nursery stock was prevented. 
IN VIRGINIA. 
Mr. Phillips reported that the practice in Virginia was to 
withhold certificate from nurseries in which San Sose scale, 
Black Knot or Peach Yellows was found until the trouble was 
effectually eliminated Peach Yellows had not so far been 
found in the nurseries, but diseased orchard trees in the 
neighborhood of a nursery sometimes occurred and these 
were destroyed before a certificate was granted. The same 
was true of Black Knot. He stated further that severe cases 
of Crown Gall, Woolly Aphis and pear blight were not ad¬ 
mitted under certificate. Plants actually showing the presence 
of such pests were discarded. 
Mr. Forbes required the Illinois inspectors to send in a 
statement of every pest found in the nursery, and before a 
a certificate was granted he required the elimination of the 
San Jose scale and the Black Knot. Precautions were taken to 
avoid sending out Borers, Woolly Aphis, Crown Gall and pear 
blight. Plants infested with Woolly Aphis to the extent of 
causing warty formations on the roots were discarded, and so 
also were plants visibly affected with Crown Gall. Crown Gall 
was common on apple in Illinois but was not found on peach. 
Noticeable infestation of the Scurfy scale and bad cases of 
Oyster-shell Bark Louse were rejected. 
Mr. Engle of Pennsylvania suggested that in these discus¬ 
sions one important insect—the Black Peach Aphis—had been 
overlooked, and that in his opinion all inspectors should rule 
against this pest. 
IN GEORGIA. 
Mr. Scott stated that in Georgia the presence of she San 
Jose scale, Diaspis pentago?ia„ Black Knot or Rosette would 
prevent the certification of a nursery ; that stock seriously 
affected with Crown Gall, Root Knot or Woolly Aphis was not 
allowed to be sent out under certificate ; and that stock in¬ 
fested with the Cherry scale, Scurfy scale or Oyster-shell scale 
was caused to be properly treated before it was sent out. . It 
had been his practice in suspicious cases to have the stock in¬ 
spected on the heeling grounds for Crown Gall, Woolly Aphis 
and scale insects. 
Referring to the statement of Mr. Forbes that in Illinois 
Crown Gall was found only on apple, Mr. Phillips stated that 
the same was true in Virginia. Mr. Scott stated that in Georgia 
fhis disease was equally common on peach and apple, while 
Mr. Smith’s observation was that in New Jersey it was confined 
entirely to the peach, and Mr. Gossard stated that the same 
was true for Florida. 
The discussion of this topic being concluded, Mr. Smith 
“ Moved that the chairman appoint a committee of three, in¬ 
cluding himself, to whom shall be entrusted the duty of com¬ 
paring all existing laws concerning insect control in nursery 
or orchard, who shall suggest points to be covered in state 
legislation, and who shall formulate suggestively uniform state 
and federal legislation to regulate nursery inspection, inter¬ 
state traffic and orchard control. Report to be made at the 
next meeting of this body.” 
AMENDED MOTION ADOPTED. 
At the suggestion of Mr. Fernald the motion was so amended 
as to couple the word “ disease ” with that of “ insect.” The 
motion was then adopted as amended. 
Topic 9.—“ A Statement by each Member of the Procedure 
taken in his State in cases of Nursery Infestation with Scale 
or other Dangerous Pests.” Mr. Scott stated that the Georgia 
law prohibited the certification of a nursery when any portion 
of it was found infested with San Jose scale or like pests, and 
that he had disposed of such cases according to the individ¬ 
uality of the nurseryman as well as the circumstances attend¬ 
ing the case, in the following manner : 
Case l.—A portion of a large nursery was found infested 
with San Jose scale, and, as agreed to by the owner, its cus¬ 
tomers were notified of the exact conditions with assurance 
that the stock actually infested would be burned and the 
remainder fumigated under supervision. To the surprise of 
both the owner and himself not a single order was counter¬ 
manded, and practically the entire stock was disposed of at 
the customary prices. 
Case 2.—Upon the inspection of a certain nursery, a single 
specimen of San Jose scale was found upon a plum leaf, and 
in spite of a most careful examination no further infestation 
could be found at that time. A second inspection at the 
heeling grounds revealed a slight infestation of a dozen or
