How often' have you walked into
your winter wheat fields this year?
Corn and bean crops tend to get more
care and lime than the often neglected
cereal crops. If it is worth growing, it
deserves timely scouting.
Many things have been happening in
and around the wheat crop since that
tractor .seat survey taken this spring
when applying Nitrogen fertilizer. How
many of you checked your wheat
fields for powdery mildew, leaf rust
and septoria this year? Most fields on
inspection had noticeable levels of one
or more of these diseases.
Premature colouring of some heads
or parts of heads in an otherwise
green field are a sure sign of head
disease. At this time .they are easier to
identify as they stand out from the
rest of the crop. This year, incidence
of head disease is rampant in this
area, some fields are showing extreme
head damage. If you have noticed this
in your fields, it is probably one of the
following:
1) Head Blight - entire heads or
parts of heads bleach while the stem
-r,Liairis green, PIA mold can develop
with prolonged wet weather. rus- arium
species are responsiblefor head blight
in wheat and barley and stalk and ear
rots in corn. The fungus .spreads to the
heads from wheat and corn debris.
Delays in harvesting brought about by
wet weather favours continued growth
of the fungus. Toxins produced ie:
vomItoxin and zearalenone can be
harmful to man and non -ruminant
animals The fungus can survive in in -

fected seeds and can be carried over
into the next wheat crop. Should these
seeds be used for planting, they may
cause seedling blight.
2) White -Head - entire heads
prematurely bleach4 with stems las-
ing green colour quickly as well.
White -heads are a setondary symptom
of disease affecting the lower part of
the stem; crowns or roots. Usually
take -all is the main disease present
caused by soil borne fungus.
3) Glume Blotch - brown or purply
areas develop on the glurnes and
awn.s. Infected areas are speckled with
tiny grey brown dots of the Septoria
fungus.
Sources of the fungus are infested
stubble and straw, volunteer wheat,
and seed. Disease develops first on the
• leaves and later spreads to heads.
Management Practices
1) Rotation - Wheat should not follow
corn or small grained cereals in the rota-
tion. Proper rotations will reduce the
severity of head blight, glume blotch,
take -all and several other diseases.
-42)--Seed-'A-eatment,s,
head blight and glume blotch can be
seed -borne. Seed from infected fields
should be treated with a broad spec-
trum fungicide before planting.
3) Pim/icicles - Experimentally
several have proven effective in con-
trolling glume blotch and reducing the
incidence ofhead blight.
If possible, wheat should be planted
following a -bean, pea or -legume sod

Area farmers have been busy harvesting winter wheat and as of Monday, Sandy Lid -
die of Anderson Flax in Luelmow, estimates that 85 'percent of the crop has been
harvested. Some varieties have been more disease resistant than others, however most
is going as manlier one. Yields are down from 1988 but a little above average, yielding
around the 75 Bushell range per acre. The hdtial payment is $20 per tonne more than
in 1988, $130 per tonne. More acres were planted for the 1989 cropping season and Mr.
Liddle expects to see .even more planted this fall, as it appears to be a very good cash

crop. Refer to Factsheet entitled
"Head Diseases of Winter Wheat".
First -aid
for siks
Ontario has an aging population of
tower silos. With this aging comes a
gradual deterioration of the concrete in
the silo walls. Eventually, the concrete
can no longer take the pressures it is
designed to withstand. The result - silo
collapse. This has happened and it's
very costly, not to mention dangerous.
So far, the problem has been worse
for stave silos, 'although castuin-place
silos are tug immune. The problem is
speeded up When "too -wet" silage is
stored or when the silo is not emptied
each year.
The solution - protect the silo's in-
terior wills. Apply a coating. There are
epoxy coatings that can be sprayed on,
but the wall must be very smooth in
order to get a good seal. Ibis is usually
only the case with a new silo, or one
that has received a "mortar type of
coating to restore the wall to its original
thickness. The alternative is to apply a
special mortar coating that gentains .an
acid -resistant compound. Ilere, one
material does both jobs - building up
the wall thickness, and providing acid
protection.
Before 'applying any coating, make
sure the wax( is clean repeat, clean!
The best way to do this is with a very
WO pressure wafer spray (Le. over
3000 PA).
Keep tn mind that likely only the bot-
tom 10 to 15 feet of wall will need tits
