EFFECT ON PLANTS OF DDT APPLIED TO SOIL FOR
THE DESTRUCTION OF JAPANESE BEETLE LARVAE

By Walter E. Fleming
Division of Fruit Insect Investigations


The use of technical DDT for the treatment of beds, plots, and
potting soil in commercial nurseries, in order that plants with soil about
their roots may be shipped outside the area quarantined because of the
Japanese beetle, was authorized on March 21, 1946. It is required that
technical DDT be applied to beds and plots at the rate of 25 pounds per
acre and mixed by cultivation with the upper 3 to 4 inches of soil, and that
it be mixed thoroughly with potting soil at the rate of 27 grams per cubic
yard. To facilitate the proper distribution of these small amounts of DDT
it is specified that each acre of beds or plots be treated with 250 pounds
of a dust containing 10 percent of DDT, or with 50 pounds of a water-
dispersible powder containing 50 percent of DDT per 1,000 gallons, and that
each cubic yard of soil be treated with 5 pounds of a 2-percent dust. It
has been found that dusts with talc or pyrophylllte as diluents are satisfactory,
but that those containing clay are too adhesive to flow freely in the
mechanical seeder and spreader.

Preliminary tests were begun in 1944 at Moorestown, N.J., to determine
whether various plants could be grown without serious injury in soil treated
with the authorized amount of technical DDT. In 1945 tests were made at
five commercial establishments, and in 1946, through the cooperation of the
Division of Japanese Beetle Control, tests were carried on at the following
54 commercial nurseries and greenhouses:

Sands, sandy loams, loams, and silt loams of the Collington, Sassafras,
Lakewood, Merrimac, and Wethersfield series, and various unidentified soils
were used in these tests, depending upon the geographical location of the
nursery or greenhouse and on the nature of the plants. In many cases the
composition and the texture of the soil were modified by the addition of
organic matter, soil conditioners, and fertilizers.

In the preliminary tests it was the practice to plant an equal number
of seeds or plants in treated and in untreated soil and to grow them side
by side under the same conditions. A large number of plants were tested
in this manner. In addition, several varieties of plants were grown on a
relatively large scale at the commercial establishments. Usually only
part of the beds or plot were treated so that the plants growing in treated
soil could be compared with those growing in untreated soil.

The object of this investigation was to determine whether plants could
be grown satisfactorily under commercial conditions in soil treated with
the authorized amount of DDT. When the general development, color, bloom,
and yield of plants in treated soil were about the same as those in untreated
soil, it was considered that the DDT had not had a deleterious effect on
the plants. However, in a few tests DDT retarded the growth of the roots
and the aerial part of the plants, produced an abnormal color, and reduced
the yield. It is realized that the results obtained with the various plants
may not be the same in other soils and under different environmental conditions,
and it is suggested that nurserymen who are interested in growing plants in
DDT-treated soil conduct preliminary tests under local conditions before
applying the treatment on a large scale.

The results of the investigations during 1946 fall into six groups,
namely (1) nursery and greenhouse plants which grew normally; (2) nursery
and greenhouse plants whose reaction could not be determined because of
winter injury or incomplete reports; (5) nursery and greenhouse plants
which were retarded; (4) cereals and grasses which grew normally; (5)
vegetables which grew normally; and (6) vegetables which were retarded.
These results are tabulated by species and horticultural names.

The nursery and greenhouse plants which grew normally in soil treated
with technical DDT appear in the following tabulation:
