Bayer CropScience Announces Registration For Use of Alion on Grapes in California

Bayer CropScience Announces Registration For Use of Alion on Grapes in

Longer-lasting herbicide provides more than six months of pre-emergence
control against grass and broadleaf weeds.

Today, Bayer CropScience announced that Alion® herbicide now has a
supplemental label that allows for application of Alion on grapes in
California. Alion is a long-lasting, pre-emergence herbicide used on grapes to
control a wide range of grass and broadleaf weeds, such as marestail
(Horseweed), that exhibit resistance to other herbicides.

Alion field trials across the United States show weed control lasting longer
than six months in fields treated with just 5 oz/A of Alion herbicide, all
without compromising crop safety. This effective weed control means Alion also
helps eliminate the competition between vines and weeds for water and soil
nutrients, ultimately protecting grape yield.

"Alion provides superior protection for high-value crops, such as grapes, and
reduces the number of in-season sprays. It offers over six months of
pre-emergence residual weed control, which is longer than the leading
competitor's products," says Nevada Smith, Alion product manager. "Its
longer-lasting control and low use rate allow growers to focus more on
profitability and less on weeds."

Smith further explained that the excellent environmental profile of Alion
should be a great fit for California. Based on the low use rate of just ounces
per acre, its chemical properties and research conducted during the
development of Alion, there should be very little movement into the soil
profile when used as directed.

The unique active ingredient in Alion is a cellulose-biosynthesis inhibitor
(CBI), which is the most effective CBI herbicide discovered to date. There are
no documented cases of resistance to its chemistry in the United States. When
applied alone or in combination with other herbicides, it can control ACCase-,
ALS-, triazine- and glyphosate-resistant weed species. Producers who use Alion
as an integral part of their weed management plan will help to prevent, manage
or delay the spread of weed resistance.

While Alion is newly approved for use on grapes, it was first approved for use
in California in 2011. Since then, it has demonstrated excellent weed control
in crops such as tree nuts, citrus, stone and pome fruit.

Alion can be applied up to 14 days before harvest for all crops except citrus,
and seven days for citrus. When applied with a contact herbicide, an Alion
tankmix provides initial burndown of emerged weeds and extended residual
