No one has a stronger Clearfield® range than Pioneer.
Pioneer's range of canola with the Clearfield® trait of herbicide tolerance covers every growing situation
and maturity. We have the only early season varieties, a new early maturing hybrid and proven mid-
All have good blackleg resistance and standability and all are high yielding. Each one is backed by our
local product advancement trial (PAT) program giving you real data from leading growers so you can be
confident they will perform on your farm. So whether you want Clearfield® canola with a 3,4,5 or 6 maturity,
a variety or a hybrid, you can count on Pioneer because we've got the strength in numbers.
Choose from the Pioneer Clearfield® canola range this year and you'll
know you're putting the right product in the right paddock.

WHEN it comes to Blackleg, a com-
mon disease affecting canola crops,
it's all about managing the risks
and therefore the impact on crop
yield, according to DuPont Pioneer
South Australia area manager Paul
"The degree to which Blackleg
affects yield depends on a number
of factors, and there's quite a bit of
information growers need to know
in order to make an informed deci-
sion on how to manage their risk,"
Mr Jenke said.
"The new Blackleg Management
Guide developed by the GRDC is a
useful tool to help ascertain what
levels of risk growers have on their
property, and what steps can be
taken to do something about it."
Key points include:
* How to determine your property's
Blackleg risk, taking into account
environmental factors including
rainfall and regional canola inten-
* Determining each paddock's
Blackleg severity by cutting canola
stems at windrowing to assess
canker levels; and
* Adopting management practices
to reduce the risk of Blackleg infec-
tion, which include choosing high-
er Blackleg-rated varieties, using
fungicides on seed (in ground or
foliar), and planting away from last
year's stubble, et cetera.
"Based on the above, many farms
won't have a high Blackleg risk,"
Mr Jenke said.
"If you assess your farm as having
a higher risk of Blackleg and stem
canker severity is shown to be
reducing yield in your previous
crop, our advice is to act now to
change management practices and
choose a cultivar with a Blackleg
rating that avoids high risk.
"Cultivars with a MR or higher
Blackleg rating are in the low-risk
category of severe yield loss from
"Also if you have high Blackleg
severity and have grown the same
variety for three years or more, it
would be useful to look at rotating.
"The Blackleg fungus will most
likely overcome seedling resist-
ance, but the presence of leaf
lesions does not indicate full resist-
ance breakdown or yield losses in
"However, effective adult plant
resistance (APR) or foliar fungi-
cides will reduce stem cankers
forming that do cause yield losses.
"Aim to select varieties that are
genetically diverse bringing a
range of APR sources.
"Pioneer's new Clearfield Hybrid
45Y86 (CL) is in a different seedling
"It is an ideal variety to use to
rotate resistance groups and avoid
finding yourself in a high risk situ-
