July 8, 2009 - The best chance of
rain for the next week is
this coming Sunday but that
certainly does not appear to
be anything large at this
point.
Other
than
weed
control,
the
main
cotton
chore
is
an
application
of
Boron
by
the
time
cotton
begins
blooming
if
you
did
not
make
any
soil
applications. Cotton
growth
will
remain
relatively
slow
until
we
get
some
soaking
rainfall.
I
have
gotten
a
few
questions
about
plantbugs
and
have
generally
found
that
most
of
the
fields
do
not
have
a
problem
currently. That
being
said,
there
are
some
fields
that
I
would
consider
borderline
but
they
are
extremely
scattered. Plantbug
activity
is
usually
more
significant
when
rainfall
is
plentiful
and
cotton
growth
is
aggressive.
I am
not
comfortable
making
a
general
insecticide
application
right
now
on
stressed
cotton. Bidrin
and
the
Pyrethroids
are
pretty
economical,
but
there
is
potential
for
flaring
up
spider
mites
or
aphids
in
these
dry
conditions.
Trimax
or
Centric
are
more
expensive,
but
will
not
flare
up
spider
mites
and
actually
can
control
aphids.
In
summary,
most
cotton
does
not
need
an
insecticide,
but
check
your
fields
for
that
isolated
exception.
Insect
pressure
(plantbugs)
low.
3 to
5%
of
fields
meeting
square
retention
concerns.
Not
enough
rain
to
change
the
growth
rate
of
cotton.
If
no
boron
is
used
in
fertilizer,
then
first
foliar
spray
should
be
made
at
early
bloom.
Almost
all April
planted cotton
is
blooming.
