U.S. Growers looking for
top-of-the-line disease control have greater flexibility in
2008, thanks to significantly reduced plant-back restrictions
for Reason® 500 SC fungicide from
Bayer CropScience.
Beginning this season, any crop on the expanded Reason label may
be planted immediately following the last application of Reason.
Strawberries or wheat may be planted within 30 days, and
sugarbeets within seven months after last applications of
Reason.
“This new label change makes Reason much more practical for
today’s vegetable growers,” says Brent Crossland, Reason product
manager with Bayer CropScience. “We’re thrilled that more
growers will now find Reason to be an attractive option that
fits their operations. And we’re confident that growers will be
thrilled with the levels of control that they achieve as they
begin working Reason into the disease management programs.”
In-field use and research trials show Reason provides
consistently outstanding control of tough diseases including:
- Downy mildew, leaf spot
and white rust in brassica and cole vegetables
- Downy mildew and purple
blotch in onions
- Cavity spot in carrots
- Pythium damping off in
cotton
- Downy mildew and leaf spot
in cucurbits
- Downy mildew, white rust
and celery late blight in leafy vegetables
- Early blight, late blight,
white rust and suppression of black dot in potatoes
- Early blight and late
blight plus suppression of Septoria leaf spot and
Phytophthora blight in fruiting vegetables
“Reason is a locally systemic,
fast-acting foliar fungicide that stops disease development at
more stages in the disease life cycle,” explains Crossland. “It
also acts against both the direct and indirect germination
cycles of many key diseases for more effective and reliable
control.”
The active ingredient, fenamidone, acts by disrupting electron
transport in the pathogen's mitochondria, which stops diseases
before they develop in the leaf tissue. This preventive
activity, combined with a strong antisporulent effect, halts
disease before it can spread to healthy leaf tissue.
After application, Reason penetrates leaf tissue with
translaminar movement to protect both the treated and untreated
sides of the leaf. The product also protects new growth because
it has very quick uptake within the plant and is locally
systemic within the leaf tissue, which helps prevent both the
development and progression of diseases in the field.
