County Agents Notes


1t seems that most farmers have
a good stand of cotton and that
the cotton crop has been growing
rapidly up until the cool weather
FRIDAY and Saturday, May Is
and 10th. Up until the early part
of last week it seems we had no
"Trip damage to cotton. The first
few leaves developed on older cot
ton were smooth and showed no
effect of insect damage but if you
will notice in your cotton fields
of today. if you have not been
poisoning, you will find young
leaves developing very slowly and
considerable damage from "Trip.
The young leaves appear crinkly
and oposSum-eared like. which is
the indication of severe "Trip dam
age during the last few days.
With the past few days of cool
weather and maturing out of gras-
ses and host plants of "Trip I be-
lieve it would be wise to spray
cotton for "Trip If you have not
already done SO, especially your
young planted cotton since May /.
For the control of "Trip you may
use aldrin, dieldrin, endrin, B. H.
c. or toxaphene. Either as a dust
or spray. If busting apply s to 8
pounds Of above materials per
acre directly over top OF cotton.
If spraying mix the above in
secticides with the following a.
mounts of water and use at least
one gallon per acre of this mix
ture.
Admin gallon technical ma
terial to 20 gallons of water.
Dieldrin-1 gallon technical ma
terial to "a gallons of water.
Endrin-1 gallon technical ma
terial to 20 gallons of water.
B. H. CT gallon technical ma
terial to Z gallons of water.
Toxaphene-1 gallon technical
to 6 gallons of water.
Be sure your nozzle tips are di-
rectly over top of cotton and not
over 6 inches above the top of
the cotton stalk.
AS yet we have not found any
boil weevils in bud of young cot
ton but if a few weevils are found
I would not bother to poison for
boil weevils until the formation of
young squares appear on the cot
ton, then be ready to poison for
boil weevils in order to prevent
your early squares from being
punctured and to kill of other
cotton insects that will damage
young squares such as fleahopper,
rapid plant bugs and a number of
other cotton insects.
See that your poison machines
are in good operating order so
that they may be used when the
time comes. Spray machines
should have at least a No. 2 tip
for controlling most insects. A No.
3 tip is preferred. The pressure of
your pump should be adequate
but not to the extent that the spray
material will be broken down so
find that they will blow off or eva
porate before hitting the plants.
Usually controlled pressure to
spray on an average day would
be 30 to 40 pounds pressure. How
ever, on real windy days it may
be necessary to lower the pressure
in order to get proper coverage.
Farmers are asking the question:
What insecticide are we going to
use for controlling boil weevils.
The insecticides that we found
last year did a good job were
malathion, methyl parathion and
guthion in sprays. These materials
did not do a good job where
busting. 1t seems that the 3 phos-
plate materials mentioned above
break down very rapidly and usu-
ally lose their strength to such a
point that they do not give salts
factory control. The only dust
that we have that IAN be recon-
mended for control of boil weevils
this year is a new material which
has given very satisfactory results
in experimental work over the past
2 or 3 years. This new dust is
called SEWN" It is a long lasting
tnsecticide and it is safe to apply.
Just as much as your old poison,
as 3-5, toxaphene, etc. Before time
for spraying or busting for boil
weevils every cotton farmer will
receive a letter giving all the re-
commended materials, amounts to
apply and how to mix.
H0rnfly Control
Hornflies should be controlled
on your livestock. Experimental
