breeding areas, or they may
sp cad the fungus from diseased
tees to healthy trees in their
feeding operation.
Cont oil recommendations for
Dutch elm disease a e: Cd Early
in the spring (befoce ApriD de-
sttoy all elm wood within few
hundred feet of elm trees. Burn
or debark the wood. (2) Prune
or remove all dead or weak elm
branches because they are pos
sible sites for beetle breeding and
feeding. (2) Elm trees that are
known to be infected should be
cut down and entirely destroyed.
"a Spraying elm trees with DOT
is a valuable control measure if
proper equipment is available.
This iinsecticide kills the bark
beetles which are the only means
of spreading the disease from
tree to tree. One application of
DOT should be made about April
1 to Is and another application
should be made about July /. 90
Keep all elm trees in good condi-
ton by applying fertilizer, spray
ing to control leaf insects and
diseases and watering to main
tain a healthy tree.
1t is suggested that the city
forester, State Forester, county
agent or State Plant Pathologist
be consulted if it is believed
diseased elm tree is a source of
infection for neighboring elms.

WEEVILS BIG EATERS
Alfalfa weevils have big appe-
tites. This was impressively dem
onstrated at the University of
Maryland agronomy'r EAR h
farm recently to about $50 people
who attended the annual Agron-
omy Field Day.
The demonstration involved
two alfalfa plots of the same size
one had been sprayed for vice.
vii control and the other had not
been sprayed.
Both plots were cut June Z.
Yield from the sprayed plot was
IA bales of leafy, good quality
hay. Only 8 bales were cut from
the unsprayed plot, and the hay
was of poorer quality. On ton
per-acre basis, the comparative
yield would be about 2 tons for
the sprayed alfalfa and about ID
ton for the unsprayed.
Two applications of inescticide
we're made on the sprayed plot.
Heptachlor was applied April 7,
and BIC was applied April 81.
1t was pointed out by the re-
search workers that control of al
falfa weevils was mainly respon-
sible for the difference in yield,
although some of the increased
yield was probably due to control
of spittlebug and pea aphids.
Field Day visitors could also
see that weevil control was bene-
fitting the second growth. Since
cutting on June 7 the sprayed
area has made four or five times
as much growth as the unsprayed
area.
Experiments on leafhopper con-
troll in the summer are being con-
Quoted on the same plots. Meth
oxychlor will be applied for this
insect. These experiments are
being conducted comparatively by
the departments of agronomy,
botany and entomology.
