THE NATIONAL NURSERYMAN. 
TREATING STOCK. 
Some Results from the Use of Gas and WhalF- 
OiL Soap in Nursery Rows—Valuable Ex¬ 
perience IN A Long Island Nursery. 
Professor F. A. Sirrine, entomologist of the State of New 
York, notes the following results from the use of gas and 
whale oil soap on nursery stock : “During the fall of 1895, 
spring and fall of 1896, and spring of 1897 Messrs. Keene and 
Foulk of Flushing, N. Y. have used hydrocyanic acid gas 
one and one-half times as strong as usually recommended 
for fumigating nursery stock ; the per cent, of purity of the 
potassium cyanide used and the space occupied by the trees 
in each case being known. During each of these periods I 
have managed to find stock that was infested with San Jose 
scale. Have had this infested stock put through the gas- 
box with other stock, and carried over to determine the effect 
of treatment on the San Jose scale and on the stock itself. 
“ In only one case has the above strength of gas been found 
not to kill all the San Jose scale on treated stock. This fail¬ 
ure was during the fall of 1895, and was found to be due to 
the fact that the workmen had neglected to place timbers upon 
the ground for the trees to rest upon when the box was in¬ 
verted. In this particular case the infested stock was cur¬ 
rants, and as they were placed on top of the other stock they 
were forced into the loose diit to such a depth by the weight 
of the stock when the box was inverted, it was impossible for 
the gas to reach them. After discovering the cause of this 
failure, care was taken to prevent the trees being pressed into 
the dirt when the box was inverted and no further failures 
have resulted. I have recently examined a lot of Pyrus jap- 
onica that had been badly infested. This stock was fumi¬ 
gated the past spring while dormant. Although Pyrus jap- 
onica usually carries a quantity of dirt on the lower branches 
which interferes with fumigation, no trace of living scales 
could be found upon it. 
“ In no case have I found stock which was fumigated while 
dormant that has shown the least evidence of injury from the 
use of one and one-half times the quantity of hydrocyanic 
acid gas usually recommended. 
“On the same date that the Pyrus japonica stock was in¬ 
spected, had an opportunity to inspect apple trees in nursery 
row which had been washed with whale-oil soap solution for 
two years in succession. Occasionally a living specimen of 
San Jose scale was found on this washed stock. 
“ The above fact should not condemn the use of whale-oil 
soap, as it has its place and is excellent for some purposes ; 
but it must not be expected to be a perfect remedy as a wash 
when used for trees in nursery row, especially in the hands of 
day laborers. 
“ I believe that in whale-oil soap carefully applied we have 
a good means of keeping the San Jose scale under control on 
growing stock, and in the fumigating box rightly used we have 
a sure means of exterminating this pest in nurseries. I 
strongly recommend the use of one and one-half times the 
usually recommended amount of hydrocyanic acid gas in 
fumigating dormant stock.”
