PRODUCTION 
United States 
The Pennsylvania Salt Manufacturing Co., Philadelphia, Pa,, announoed 
on February 14, 1945, that it nad completed installation of facilities 
for the manufacture of DDT on a commercial scale and that production had 
begun.— Anon. (21) • 
DDT was being made early this year by 13 producers and production 
must now [March, 1945J be close to 2,500,000 pounds monthly as compared 
with the starting output of 1,000 pounds in April 1943.— Stenerson (336). 
At present fApril 1945] United States is producing more than thirty 
million pounds of DDT per year, practically all of which is being used 
by the armed forces in one form or another. Unless wide insect control 
projects are developed in the postwar period, normal consumption of DDT 
for regular civilian uses is estimated to be a small fraction of this 
tonnage. -r-Peaker (291 ) . 
The DuPont Company first made DDT at an experimental plant at 
Cleveland, Ohio, and the first lot, 500 pounds, was shipped overseas 
shortly after American troops landed in Italy.—Anon. (38). 
Sweden 
In March 1945 commercial production of DDT was to be taken up by 
the a/B Mo och Domsjo at its Domsjo plant.— Anon. (37). 
DDT, introduced into Sweden in 1943 as Gesarol, has been used 
principally for plant protection, although experiments are under way to 
develop products for veterinary and human use. Between 60 and 80 tons 
were consumed in 1944, both of the Swiss type and the cheaper Swedish 
type.— Anon. (59). 
ALLOCATION 
The War Production Board relinquished all oontrol over DDT in 
September 1945 but it is of interest to review the sibiation during the 
time covered by this digest (January- June, 1945) • According to a stat~ 
ment issued January, 1945, by the U. S. Department of Agriculture, the 
armed services will need all available DDT. For many agricultural 
pests suitable inseotlcidal mixtures and dosag©6 have not yet been 
worked out and possible harmful effects of DDT insecticides on soils 
and plants are not fully known .--Anon. ( 12 ) • 
On February 12 the War Production Board announoed that a limited 
quantity of DDT* could be obtained directly from suppliers without direct
