ALFALFA WEEVIL DAMAGE on the plant at
left shows up as lacy leaves near the tip of the
plant. Stalk at right shows very little damage. A total of
nine weevil larvae were on the terminal bud of the
plant at left. The field shown here was treated last
fall with Dieldrin. L. F. Photo.

tions of eggs, laivae, pupae,
and adult weevils in fields

heptachlor or dieldrm accord
ing to lecommendations Heavi
est infestations wete found in
older fields wheie dieldiin. •or
heptachlor have been used for
two or thiee consecutive years;
the lighter infestations in new
stands appeals to show that
the weevils have built up an
immunity to the chemicals.
The problem will piobably
last into June, Pepper said,
since eggs wei e found in large
numbers. Normally, the wee
vils hatch at about the same
time, and spray lecommenda
tions can be timed to control
the larvae or worm stage, but
■with the pests in all stages,
control programs aie hard to
devise.
Two major concerns faced
county farmers this week. What
can he done about the present
crop, and how can later cut
tings he protected?
Peppei lecommended imme
diate harvesting of hadly in
fested fields, if giowth is high,
enough to warrant it, and
spraying of the stubble two on
three days after harvest.
If the crop is a week away
fiom desirable haivest time,
the spiay can he applied and
the crop harvested a week lat
ei In no case should spiayed
fields he haivested inside sev
en days, he said.
Peppei said any one of four
materials can he used as stub
ble spiay Guthion, 25 per cent
emulsion, should be applied at
two pints per acie. Methoxy
chloi, 25 pei cent emulsion, at
two quarts pei acte, Diazinon,
500 emulsion, one pint per
acie, oi Malathion, five pounds
pei gallon emulsion, at the
rate of V/z pints pei acre.
Foi new stands eithei meth
oxychloi of malathion can be
applied seven days befoie har
vest The methoxychlor should
be put on at three quaits per
acre, and the malathion at iVa
pints
Lueck said in most cases, the
oldei stands should he harvest
ed first, letting the new crops
get as much giowth as possible.
Lueck said that of over 200
fields inspected over the last
two weeks, only 20 treated last
fall with heptachloi or diel
dnn had weevil control, and
those were fields where the
spray was applied last fall for
the first time.
Pepper reminded farmers
that ‘ absolutely no heptachlor
or dieldun may be spiayed on
hay fields this spring or sum
mer.”
‘He also pointed out that
stuibble spiay applied for 'wee
vil control will not control leaf
hoppers He i ecommended a
spray of methoxychloi when
the new growth is six inches
high
Non-Chemical Control
Meanwhile, a ciash piogram
on non-chemical methods of
pest control was urged toy the
National Agucultuial ißeseaich
Advisoiy Committee in its quar
terly lepoit to the U S. De
partment of Aguculture.
‘lnci eased lesearch on how
pesticides function and what
happens to them aftei use, to

committee said
Still more emphasis is need
ed on biological conti ols, at
tractants, repellants, steriliza
tion techniques and resistant
crop varieties, the repoit said.
In an attempt at biological
control of weevils, two species
of parasitic wasps have been
