THE NATIONAL NURSERYIVIAN 
(lestructivo to honey bees, perhaps a vine would entrap 
lifteen or twenty bees during a season. 
This vine is worthy tlie attention of all of our experi¬ 
ment stations to test, espeeially for the destruetion of the 
eodlin moth. If is a sure thing that this vine attraets 
the eodlin moths in large numbers during its blooming 
season, and that these are entrapped and killed by thou¬ 
sands. 
In the Andes Mountains we are assured that there are 
many types of early and late blooming physianthus, us 
well as almost perpetual blooming speeies. We are work¬ 
ing with the end in view of obtaining and testing all the 
various types as rapidly as we ean. Also we hope to 
further imporve the present ])hysianthus which we have, 
in the way of producing a better type for the destruetion 
of the eodlin moth. 
Physianthus albens from an ornamental standpoint is 
one of great beauty, and if it will succeed in all localities 
in exterminating moths its culture should be widely ad¬ 
vised, but if it will oidy succeed in a few places the 
sooner we know this the better About the best way to 
test this is to have all the experiment stations throughout 
the United States test this plant in all the various local¬ 
ities, and if successful to try and grow and propagate bet¬ 
ter sorts. That this plant is susceptible to great improve¬ 
ment in a short time is attested by its wide variation when 
grown from seeds. 
I do not advertise this as a vine universal in its effects 
to exterminate the eodlin moths but rather as an untried 
experiment, and something well worth looking into. 
However it does the work here, will it do it in other loca¬ 
tions is the question. 
Why it does not injure honey bees to any great extent 
I believe is that this gummy substance exudes freshly 
each night, or as soon as the sun goes down. The 
morning sun dries this up. so that bees ean work on this 
plant with no apparent loss all day long. The moths do 
all their flying at night or towards evening, so they get 
thoroughly entangled. I have a bee ranch here so I ean 
observe pretty closely the traits of this plant towards in¬ 
juring bees. I would not recommend any plant that 
would be of injury to the bee business. 
An event of considerable importance was the British 
Government order prohibiting importation of trees, plants 
and bulbs from foreign countries. The bulb merchants 
unquestionably suffered some inconvenience and loss of 
turn over, but the restrictions did us a good service in that 
both the trade and the public have been aroused to the fact 
that Bulb-farming in the British Isles is a branch of com¬ 
mercial horticulture, with possibilities for extensive de¬ 
velopment, So far as Fruit and Ornamental Trees, 
Roses, Perennials and other plants are concerned, nur¬ 
serymen have cause to be grateful that the dumping of 
these into our auction rooms and market places has been 
checked, and if the Trade is alive to its own interests no 
effort will be spared to ensure that its advantages shall 
not be too lightly thrown aside as soon as war is over.—

PEACH SCAB CONTROL 
Peacli scab, n\ liicli ranks next to the destructive brown 
rot in economic importance among peach diseases in the 
United States, and which at one time seriously menaced 
the success of commercial peach culture east of the 
Rocky Mountains, can be successfully controlled at small 
cost by spraying, according to a professional paper. 
Bulletin 31)5, recently published by the U. S. Department 
of Agriculture. Self-boiled lime-sulphur and a solu¬ 
tion of linely divided wettable sulphur, which is a mix¬ 
ture of superline sulphur, glue, and water, have been 
proved by experiments to be the best of the known 
sprays in controlling the scab. The applications can 
be made in commercial orchards at an average cost not 
exceeding live cents a tree. In certain experiments 
carried on by plant specialists of the Department of 
Agriculture such si)rayings resulted in an increase in 
profits of about $1,50 per tree. 
The spraying for scab may be combined advantag¬ 
eously with treatment for other diseases, such as brown- 
rot, and insect pests, such as the plum curculio. If this 
plan is adopted, the following spraying schedule is sug¬ 
gested : 
Early varieties.— The early varieties, such as the 
Greensboro, Carman, Hiley, and those with similar ripen¬ 
ing periods should be sprayed as follows: 
(^1) With arsenate of lead and lime about ten days 
after the petals fall. This application may be omitted 
in sections where the curculio is not a serious factor. 
(2) With arsenate of lead and self-boiled lime-sulphur 
or linely divided wettable sulphur about a month after 
the petals fall. If the latter type of fungicide is used, 
the addition of lime, as in the first treatment, may be a 
desirable precaution against arsenical injury, 
(3) With linely divided wettable sulphur or self- 
boiled lime-sulphur three to four weeks before the fruit 
ripens, but not less than four weeks before haiwest if 
self-boiled lime-sulphur is used. This application may 
be omitted in sections where brown-rot is not seriously 
injurious. 
Midseasox varieties.— The treatment recommended 
for early peaches is applicable likewise, to midseason 
varieties, such as the Reeves, Belle, Early Crawford, El- 
berta. Late Crawford, and Fox. For such varieties, 
however, the third application is very essential and 
should not be omitted where brown-rot or scab injury is 
serious. 
Late varieties.— The Salway, Heath, Bilyeu, and var¬ 
ieties with similar ripening periods should be treated as 
midseason varieties, with the addition of an application 
of the fungicide alone about a month after the second 
treatment. 
The following concentrations of spray preparations 
are recommended: Arsenate of lead paste, IF 2 pounds 
(powder, three-fourths pound) in 50 gallons; stone lime, 
2 to 3 pounds in 50 gallons; self-boiled lime-sulphur, 8 
pounds of lime and 8 pounds of flour of sulphur in 50 
gallons; and finely divided wettable sulphur, 5 pounds 
in 50 gallons in the case of the paste (approximately 50 
per cent sulphur) used in the foregoing experiments.
