MISCELLANEOUS ITEMS 
CALLS CONFERENCES TO CONSIDER CONTROL OF THREE PLANT PESTS 
(Press notice) 
October 8, 1934. 
Three public conferences to analyze and consider the status of three im- 
portant plant pests, the white pine blister rust, gypsy moth, and Dutch elm 
disease, will be held in Washington, D. C, on December 3, 4, and 5, 1934, 
Lee A. Strong, Chief of the Bureau of Entomology and Plant Quarantine, 
announced today. 
These conferences will consider the present value of the control programs, 
their need and effectiveness, whether they should be continued, and the de- 
sirability of making modifications or changes. In announcing these confer- 
ences Mr. Strong stated that they were for the purpose of bringing to public 
attention all available facts and opinions concerning the pests and to ascer- 
tain public sentiment regarding the control programs and the quarantines 
enforced in connection with them. It is proposed to find out at these hearings 
just how much benefit has resulted from the efforts which have been made 
and to determine whether the cost of continuing them is justified. Any 
person or group interested in these subjects — the modification of the control 
and eradication programs, the revocation of the quarantines on account of the 
white pine blister rust and the gypsy moth — may appear at the conferences 
and be heard, either in person or by attorney. 
These conferences are scheduled to meet in the auditorium of the Depart- 
ment of Agriculture at 10 o'clock each morning on Monday, Tuesday, and 
Wednesday, December 3, 4, and 5. The auditorium is located on the first 
floor, between wings 5 and 6, in the new Extensible Building. The entrance is 
on Independence Avenue (B Street) SW. 
The conference of December 3 is to consider the program of the work and 
the quarantine on account of the white pine blister rust. The control work 
on white pine blister rust is now carried on in cooperation with 31 States 
and agencies administering public lands such as the Forest Service, National 
Park Service, and the Indian Service. 
The white pine blister rust was first introduced in the northeastern United 
States from Europe about 1898 and into Vancouver, British Columbia, in 
1910. It is recorded in New York in 1906 and on native pines in the North- 
eastern States in 1915. The first Federal appropriation for blister rust con- 
trol work was made in 1916. Since that time the Federal Government and 
States have appropriated sums totaling more than $11,000,000 to combat this 
disease. It is particularly 'destructive to white pine and has as its alternate 
host certain species of currants and gooseberries. 
The conference of December 4 is to consider the present program for the 
control and prevention of spread of the gypsy moth. The gypsy moth is well 
established in parts of the New England States and recently extensive in- 
festations have been found in parts of Pennsylvania, on Long Island, and in
