Publishing House who is managing the sale qf
prints for Communiversity. there are "a couple

Kaufman receives
$5000 art grant
Boll weevils, the legendary
scourge of the Cotton Belt, can
be controlled more effectively,
using less poison, as a result of
Dr J B Weaver’s development
of weevil repellant cotton
plants, he claims.
Weaver, an agronomy pro
fessor at the University, is
testing methods of planting
weevil-repellant cotton with
weevil-attracting cotton By
poisoning only the weevil-at
tracting rows, less pesticide is
needed. Weaver said.
Boll weevils were restricted
to Southern Mexico until the
1860s. when Federal blockading
of Southern ports encouraged
cotton growing in Texas and
Northern Mexico, Weaver said
The boll weevils made their
way across the Rio Grande by
1892. and into Georgia by the
1920s. he said.
Before the weevils arrived,
Georgia was the leading produ
cer of cotton with about 5
million acres in 1920, Weaver
said

only about 240,000 acres of
cotton, because until 1946. and

Glen Kaufman, professor of
art at the University, has
received the Craftsman Fel
lowship Grant for $5000 from
the National Endowment for
the Arts.
Kaufman described the grant
as very open-ended. “This
grant is marvelous from my
|x>irf$ of view. As long as I'm
forwarding my own creative
work, I’m sure what I do is
quite fine with the endow
ment,’’ he said.
The grant does have some
restrictions, Kaufman added
The grant money is required to
be spent in one of three areas:
materials and equipment, re
lease time, to travel
Kaufman received the grant
after submitting slides showing
his work of the past few years,
which consists of abstract con
structions with fibers and rela
ted materials. In recent years
he has incorporated plastic
materials such as polyethyl
ene, vinyl film, and foamed
polyethylene rods into his
works
“You don’t see too' many
people working with these
kinds of materials," he said,
adding that plastics are gener
ally not too easy to work with
because "they have a mind of
their own. They don't act like
natural fibers. They are slip
pery, they don't bend, they don't
knot, they don't do a 'lot of
things.”
Kaufman's constructions,
which range from seven to 10
feet in height, are usually free
hanging, enclosing and defin
ing space. He said that many
people call them woven sculp
tures. Much of his work is
inspired by traditional gar
ment forms.
The structure shown to the
National Endowment was a
cape-like structure based on a
traditional Japanese form,
according toKaufman. Headded
that "the original garment is
usually made of rice straw,
and that excited me since it
was made of fiber and I'm
involved in that. It generated
my thinking into using that
form and that process to
create something that is relat
ed to the original, yet is quite
different.”
Kaufman said his goal is not
to do what is uncommon, but to
"use whatever process seems
right for whatever project or
idea I have in mind. I don’t
feel narrow about choosing
whatever process seems right
for the occasion."
Kaufman, who said that he
also has an interest in smaller
things, has two miniature,
hand-woven gloves on exhibit
now in Visual Arts.
"The whole idea of gloves as
an object that goes beyond its
| tpere use intrigued me, and the
idea of doing something small
and intimate also intrigued
me," Kaufman said These
gloves are parj of a collection
that has been on display at the
International Exhibition of Mi
niature Textiles in London.
Kaufman said that two of his
beaded gloves are showing in
London now.
He has exhibited in 12 one-
man shows since 1962 and has
been included in more than 35
group exhibitions since 1969
His work is in a number of
private collections and is on
permanent display at several
museums and universities.
the invention of DDT. cotton
farmers had no effective con
trol over the weevils, Weaver
said.
Weevils attack cotton by
boring into the buds The
larvae eat the pollen in the
buds, and they fall to the
ground. Weaver said. Buds
that fall off the plant cannot
develop into cotton bolls, so the
more weevils that attack a
plant, the less cotton that plant
will produce, he said.
Weevils prefer green-leaved
to red-leaved cotton, they pre
fer normal to male-sterile (pol
lenless) cotton, and they prefer
normal cotton buds (which are
hidden in a leafy growth called
a bract) to frego cotton buds
(which lay exposed in the
bract), he said.
THUS THE most effective
cross-breed in deterring boll-
weevils is the red, male-sterile,
frego cotton. Weaver said. But
unless the weevils have a
phoice, they will attack any
variety of cotton, he said.
To give the weevils a choice,
eight row strips of weevil-re
pelling cotton must be alter
nately planted with two-row
strips of weevil-attracting cot
ton, Weaver said.
This way, the framer can
poison the attracting rows with
a tractor-attached sprayer, he
said
Weaver's one-acre test plot
is planted with red frego as the
weevil-repelling cotton, and
green male-sterile as the wee-
vill attracting cotton
BY POISONING the green,
male-sterile trap rows, the
weevil is at a double disadvan
tage. Weaver said Those wee
vils not killed by the insecti
cide lay their eggs in the
male-sterile buds
Since the male-sterile buds
have no pollen, the young
weevils' food supply is greatly
reduced, which likewise redu
ces their chances of reaching
maturity. Weaver said.
One disadvantage of the
male-sterile bud's lack of pol
len is that it must be pollinated
by bees, Weaver added
In the test plot. Weaver said,
49 per cent of the green,
male-sterile buds had been
punctured, indicating a high
weevil population, while only
one per cent of the red, frego
buds had been punctured
THE GREEN rows, constitu
ting 21 per cent of the plot,
were poisoned five times,
Weaver said. That is a per-
acre coverage of only 1.05
applications, he said
One farmer said he had
poisoned his cotton 17 times,
Weaver added The trap row
method cuts insecticide appli
cation by at least 80 per cent,
he said.
Weaver said he expects from
three-fourths to one bale per
acre from his test plot, which,
he said, is a "pretty good"
yield.
Sex traps can also be used
against the boll weevils, Wea
ver said Traps baited with the
mating scent of female weevils
have limited success in catch
ing male weevils before they
can mate, he said.
OTHER HAZARDS to cotton
that Weaver hopes to control
with his trap row method are
boll worms, boll rot, and late
development of the cotton bolls.
Boll worms, which also at
tack the boll buds, lay their
eggs on the nectar-producing
glands on the leaves of normal
cotton plants They also prefer
hairy leaves to smooth leaves,
Weaver said.
Therefore, Weaver said, he
is planning to use hairy-leaved
plants in the trap rows, and
nectarless plants in the repel-
Dirth defects
are forever.

you help.
