Rotation of Seed Traits Encouraged in Corn-on-Corn Systems

GOLDEN VALLEY, Minn. - August 21, 2007 — First it was crop rotation. Then it was herbicide rotation. Now, crop specialists are emphasizing trait rotation as farmers plant more corn-on-corn to keep up with the growing ethanol demand.

“We’ve witnessed a historic shift in the Midwest, with total corn acreage increasing by nearly 20 percent over 2006,” says Tracy Mader, marketing manager for Agrisure® Corn Traits, Syngenta. “Many of these new corn acres were planted into last year’s corn crop, which raises the importance of trait rotation to maintain yield potential while optimizing weed and insect control.”

Cultivation is currently the only post-emergent control option for volunteer corn in conventional corn hybrids. Mader says that makes herbicide-tolerant varieties very desirable for second-year corn-not only for weed control, but also for convenience.

“Agrisure GT, for example, allows for glyphosate application to control non-GT volunteer corn, while Agrisure CB/LL allows for control of conventional or GT hybrid volunteer corn with LIBERTY® herbicide (glufosinate),” says Mader.

Like soybeans, corn can suffer significant yield loss through competition from volunteer corn. In a University of Illinois study, volunteer corn infestation reduced yield of GT and LibertyLink® (LL) corn by 42 percent and 60 percent at two Illinois test locations (Urbana and Dekalb) compared to GT corn plots treated with glyphosate and LL corn plots treated with glufosinate.

“Because the test plots were uniformly seeded with volunteer corn, these yield losses may be higher than what you might see under field conditions,” points out Aaron Hager, University of Illinois extension weed specialist and coordinator of the study. “In the field, volunteer corn infestations usually include some combination of clump corn, which is not as competitive. But that doesn’t change the take-home message, which is that volunteer corn must be controlled to prevent yield loss in corn-on-corn.”

At the Dekalb facility, glyphosate provided complete control of volunteer corn in GT corn plots and yielded 219 bushels per acre. Glufosinate provided 90 to 92 percent control of volunteer corn in LL corn plots and yielded 205 bushels per acre.

“If your second-year corn follows a conventional hybrid, then you can use your choice of GT or LL corn to expand your weed control options,” says Mader. “But when your second-year corn follows a herbicide-tolerant hybrid, trait rotation becomes essential.”

Agrisure GT/CB/LL and Agrisure 3000GT (GT/CB/LL/RW) stacked traits combine glyphosate tolerance with glufosinate tolerance, leaving open the choice of over-the-top weed control. Mader says the combination gives growers the flexibility of using either glyphosate or glufosinate on volunteer corn based on the level of weed pressure and the previous year’s corn traits.

Taking the lead in trait rotation, Syngenta is also emphasizing the importance of soybeans in the trait rotation equation. “Planting soybeans every third year gives you the agronomic advantages of crop rotation and provides an opportunity to clean up herbicide-tolerant volunteers with alternate chemistry,” adds Mader. “It’s a critical step in volunteer corn management.”

In time for 2007 planting, the EPA approved Agrisure CB/LL/RW, a triple stack corn trait that combines glufosinate tolerance with industry leading rootworm and corn borer protection. The Agrisure RW trait, available individually and in stacks, is fully approved for planting in the U.S. Syngenta is taking all necessary steps to obtain Japanese export approvals for Agrisure RW as quickly as possible, and implemented a comprehensive grain marketing program for 2007 to direct the grain to domestic use markets such as livestock feed.

For 2008 planting, Syngenta will add Agrisure 3000GT, a quad stack that provides rootworm protection, control of European corn borer and tolerance to both glufosinate and glyphosate herbicides. In addition to these new stacks, Syngenta is currently developing additional traits to enhance corn-on-corn production, including broad lepidopteran control, drought tolerance, nitrogen utilization, second-generation corn rootworm resistance and amylase corn for enhanced ethanol production.

New technology will offer effective, affordable broad-spectrum weed control in corn, soybeans

DECATUR, Illinois — August 28, 2007 — Dow AgroSciences announced details today of an exciting,
new family of herbicide tolerance traits currently in development that could be available in corn by 2012.

Known currently as Dow AgroSciences Herbicide Tolerance, this innovative technology will improve weed control in herbicide-tolerant crops, said Tom Wiltrout, Global Business Leader – Corn for Dow AgroSciences, during a news conference at the company’s Farm Progress Show site.

Standing in front of a field plot of corn containing the new trait, Wiltrout said Dow AgroSciences Herbicide Tolerance will be stacked with the HERCULEX® Insect Protection (www.HERCULEX.net) family of traits to provide growers the broadest-spectrum, in-plant insect protection available and the best herbicide tolerance package.

“Dow AgroSciences Herbicide Tolerance traits will provide tolerance to certain broadleaf and grass herbicides, including the phenoxy auxins like 2,4-D, as well as aryloxyphenoxypropionate ‘fop’ grass herbicides,” Wiltrout told the ag media gathered at a press event held at the company’s Farm Progress Show site.

Wiltrout said Dow AgroSciences was working with 2,4-D for several reasons.

“2,4-D is an effective and affordable broadleaf herbicide, and it’s registered for postemergence use in corn and the burndown phase for corn and soybeans,” he said. “Growers are very familiar with 2,4-D and its performance, and despite its long history of use, few resistant weed populations have been identified.”

The introgression of new traits into elite genetics and the completion of regulatory processes to allow for commercialization typically take several years. Dow AgroSciences estimates launch timing for this technology at 2012 for corn and 2013 or 2014 for soybeans.

The company also will apply for approval of these traits with the regulatory bodies of its main trading-partner countries and will pursue both import permits and cultivation approvals in key countries.

“Dow AgroSciences anticipated that the rapid adoption of glyphosate tolerance traits would likely result in broadleaf weeds developing tolerance to glyphosate,” Wiltrout said. “Coupling Dow AgroSciences Herbicide Tolerance technology with other currently available herbicide tolerance traits will allow growers to use multiple modes of action to improve control of broadleaf weeds that are becoming more problematic.”

Wiltrout added that Dow AgroSciences is launching two new soil-applied herbicides that will be ideal for use in herbicide-tolerant crops. SureStart™ herbicide (www.SureStart.com) in corn and Sonic™ herbicide (www.SonicHerbicide.com) in soybeans both contain multiple modes of action that provide residual weed control in herbicide-tolerant crops.

Pioneer® brand hybrids with Herculex XTRA Protection significantly better than competitors in field trials for second straight year

DES MOINES, Iowa, August 20, 2007 - Research conducted by the University of Illinois shows that Pioneer® brand corn hybrids with Herculex® XTRA traits were significantly better at protecting corn roots than hybrids with the YieldGard® VT Triple trait under very high rootworm pressure.

In University of Illinois trials in 2006 and 2007, Pioneer hybrids with the Herculex XTRA trait showed consistent, excellent protection against corn rootworm.

“The University of Illinois research results confirm that, in Pioneer hybrids, Herculex XTRA is The Better BtTM” DuPont Vice President and General Manager and President of Pioneer Dean Oestreich says. “Pioneer hybrids with the Herculex XTRA trait provide proven, excellent protection to corn roots. Growers can plant hybrids with the Herculex XTRA trait and feel confident that this will protect corn roots, regardless of the level of rootworm pressure.”

The University of Illinois results match other studies conducted this season by Pioneer Agronomy Sciences across 16 locations throughout the Corn Belt, showing Pioneer hybrids with the Herculex XTRA trait consistently provide excellent rootworm control in all pressure levels better than or equal to other in-plant corn rootworm traits.

In addition, these studies show that the Pioneer hybrids with the Herculex XTRA trait provide consistent results in protecting corn roots from rootworm damage regardless of rootworm pressure under a range of growing conditions. This complements studies done in previous years showing consistent, excellent protection from the Herculex XTRA trait against corn rootworms.

The University of Illinois trials, released in its newsletter dated Friday, August 17, 2007, evaluated a variety of corn rootworm management technologies including in-plant biotech traits, insecticide seed treatments, and granular and liquid insecticides. All were compared to unprotected checks. Test results were released from Monmouth, DeKalb and Urbana, Ill.

In the Urbana, Ill., location, Pioneer hybrids with Herculex XTRA insect protection provided superior protection to DeKalb® brand hybrids with the YieldGard® VT Triple trait. Pioneer® hybrid 33T59 with the Herculex® XTRA trait had a root rating of 0.49, significantly better than the DeKalb product DKC61-69 with the YieldGard VT Triple trait that rated 0.84. The check hybrids had root ratings as high as 2.86, showing very high corn rootworm infestation. Evaluations were based on a 0-3 root node injury scale.

In 2007 Pioneer trials, Pioneer hybrids with the Herculex XTRA trait also showed a significant difference between it and competitors in high corn rootworm pressure situations. In a study in Readlyn, Iowa, root ratings for Pioneer hybrids with the Herculex XTRA trait were 0.34, while DeKalb hybrids with the YieldGard Plus trait were 0.80 and Northrup King® hybrids with the Syngenta Agrisure® RW trait were 1.47. The check corn hybrids at the Readlyn site averaged 2.65, indicating high pressure.

In the remaining Pioneer trials, Pioneer hybrids with the Herculex XTRA trait showed consistent and excellent results.

Herculex® XTRA protection is a combination of Herculex® RW and Herculex® I traits for the broadest in-plant insect protection in the industry. In addition to defending the plant by controlling western, northern and Mexican corn rootworm, Herculex XTRA helps protect against European and southwestern corn borer, western bean cutworm, black cutworm and fall armyworm.

“Pioneer customers can be assured that the traits and the high yielding genetics offered in Pioneer products have been tested across a broad range of geographies and under a variety of growing conditions,” Oestreich says. “The Pioneer focus is to bring the greatest value to each acre of land with the latest technologies and greatest choices, year after year after year.”

ST. LOUIS, Mo., Aug. 20, 2007 - Corn rootworms are among the most damaging insects that farmers must battle, and drought conditions in parts of the Corn Belt this season, such as Indiana and Ohio, can exacerbate the impact of this pest.

Under normal conditions, with adequate rainfall, corn plants can withstand a certain amount of rootworm feeding, according to Clint Pilcher, Monsanto Corn Insect Traits Technology Development Manager. But in severely dry conditions, he explained, damaged roots make it more difficult to absorb limited subsoil moisture and nutrients, compromising plant health and yield potential.

“With plenty of moisture, a corn plant can compensate for some feeding, but without adequate moisture, it is less able to recover,” Pilcher said.

Pilcher noted that corn hybrids with Monsanto’s new YieldGard VT(tm) technology are performing well this season, even under severely dry conditions. Root digs in dry regions show that the YieldGard VT roots are well protected, supporting more efficient uptake of moisture than conventional corn hybrids.

“We are seeing several cases in Indiana and Ohio and parts of eastern Illinois where YieldGard VT Triple(tm) plants are 12 to 18 inches taller than corn protected with soil insecticides,” he said. Pilcher noted that dry weather poses a risk even when rootworm pressure is lighter than normal levels. “In dry areas, it doesn’t take extreme pressure to observe differences in plant performance,” he says.

Pilcher noted that similar results are being seen in 22 stress mitigation plots that Monsanto is monitoring this season across the Corn Belt. To keep out moisture, tents have been erected over the plots which have also been infested with rootworms to determine how YieldGard VT and conventional hybrids respond to insect pressure under dry conditions. At mid-season, YieldGard VT Triple plants were taller and healthier than corn plants with insecticides or no protection.

Pilcher encourages farmers to conduct digs to assess the level of rootworm feeding in their corn fields and if necessary to consider management options, such as in-plant insect protection, for next season.

YieldGard VT technology provides growers with improved consistency, even better insect control and higher yield potential than the first generation of YieldGard® products. YieldGard VT Triple products, planted by about 2,000 farmers across the Corn Belt this season, combine YieldGard VT Rootworm and Roundup Ready® 2 technology with YieldGard Corn Borer.

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.

GOLDEN VALLEY, Minn. - August 15, 2007 — Syngenta announces the
availability of Agrisure(r) 3000GT, the latest addition to the Agrisure
brand of high-performance corn traits, for the 2008 planting season.
Agrisure 3000GT is a quad stack that protects the corn crop against both
corn borer and corn rootworm while providing exceptional tolerance to
in-season applications of both glyphosate and LIBERTY(r) herbicides.

Agrisure traits feature the insect control and herbicide tolerance
growers need to protect the full genetic potential of their hybrids.
Agrisure 3000GT combines the powerful, proven glyphosate tolerance of
Agrisure GT with the superior insect resistance provided by Agrisure
CB/LL/RW, which has demonstrated a 42 bu/A yield advantage over the
untreated isoline in field trials. With built-in tolerance to glyphosate
and LIBERTY herbicides, growers also enjoy a trait solution for either
glyphosate- or glufosinate-tolerant volunteers in corn-on-corn
rotations.

“Agrisure 3000GT gives growers more freedom than ever before to maximize
yields and capitalize on higher grain prices and new market
opportunities,” says Tracy Mader, Agrisure brand manager, Syngenta
Seeds. “Additionally, growers can have confidence that the advanced
trait insertion process used by Syngenta protects the existing yield
potential of the hybrid.”

Syngenta maintains the genetic integrity of the hybrid by integrating
trait genes such as Agrisure 3000GT directly into elite seed lines. The
result is a rapid, efficient transfer of the desired DNA into new
hybrids for outstanding insect control and herbicide tolerance without
compromising the performance of the hybrid.

“Growers can plant this quad stack knowing that they have built-in
insect protection and herbicide tolerance, and a hybrid that is still
going to perform to its highest potential,” Mader adds. “Plus, with
their purchase of Agrisure corn traits, growers are eligible for
AgriEdge(r) Corn programs.”

AgriEdge Corn programs help increase productivity by minimizing
yield-limiting factors throughout the season. Industry-leading crop loss
and replant assurances help minimize risk while the industry’s most
comprehensive portfolio of seeds, services and crop protection products
helps to maximize yield.

“AgriEdge lets growers enjoy unmatched flexibility,” says Rex Wichert,
AgriEdge corn business manager, Syngenta. “If a grower plants a hybrid
containing Agrisure 3000GT, but does not use the GT or LL trait,
Syngenta reimburses the grower for the full value of the unused trait.
This feature allows growers flexibility in focusing on yield potential
and only paying for the technology they use.”

Syngenta introduced Agrisure biotech traits for corn in 2005 with the
launch of Agrisure GT. The Agrisure traits lineup has grown
substantially and now includes Agrisure GT, Agrisure LL, Agrisure CB/LL
(season-long corn borer control), Agrisure GT/CB/LL, Agrisure RW and
Agrisure GT/RW. Today, Agrisure traits are available in elite genetics
from Garst(r), Golden Harvest(r), NK(r) and more than 150 other seed
brands.

Agrisure 3000GT has full U.S. government approvals for planting in the
U.S. Syngenta is seeking full regulatory approval in Japan, as well as
other major export markets of U.S. corn and corn products. In 2007,
pending key export approvals, Syngenta developed a program to make
Agrisure RW technology available to those growers who submitted a plan
to direct their grain to domestic markets, such as on-farm livestock
feeding, domestic feedlots, and ethanol plants that are not exporting
distiller’s dry grains (DDGs).

Product Provides Fast, Effective Burndown and Cleaner Fields at Planting Time

Philadelphia, July 25, 2007 — A new option for quick burndown of winter annuals and other tough broadleaf weeds in multiple cropping systems is now available from FMC Corporation (NYSE:FMC). Rage™ D-Tech herbicide has received approval from the U.S. Environmental Protection Agency (EPA) for use in a variety of crops for fast, consistent burndown of a broad spectrum of weeds.

Rage D-Tech is an economical option for consistent control of winter annuals, including marestail, henbit, dandelion, shepherdspurse and mustards; and other broadleaf weeds, including bindweed, waterhemp, lambsquarters, velvetleaf, ragweed and smartweed. The product is labeled for use in no-till treatments in soybeans, corn, and sorghum, plus in-crop use in corn, sorghum, pasture and range grasses, and small grains, including wheat, barley, oats and rye, and as a harvest aid.

“Rage D-Tech is an integral part of a burndown program that prepares fields for planting a season ahead of time to help growers increase yields and get more for their money,” says Aaron Locker, Rage D-Tech product manager for FMC Agricultural Products. “It’s highly effective and works fast. Growers can actually see the results just a few hours after application.”

Figure 1 shows the efficacy of Rage D-Tech on burndown of kochia and puncturevine, in a trial conducted by Kansas State University. These control measurements were taken just four days after treatment. Figure 2 compares usage rates of Rage D-Tech and 2,4-D and related percent control of taller weeds just six days after treatment, in a trial conducted at the University of Nebraska. The fast-acting herbicide allows growers to plant earlier in the following season to get the most out of every acre. Two modes of action work together for complete burndown of tough, fall broadleaf weeds that will allow growers to plant into cleaner fields the following spring season.

Researchers in the Midwest and Delta regions have identified certain varieties of broadleaf weeds as glyphosate-resistant, including waterhemp, ragweed and marestail. Rage D-Tech is a viable option for growers to control these problem weeds and help maintain a clean field throughout the growing season, as shown in Figure 3.

For control of small weeds six inches tall or less, apply Rage D-Tech at a rate of 0.5 pt/A. Applied with a residual soybean herbicide in the fall, this combination provides outstanding burndown plus residual control allowing growers to spread out their work load while achieving effective weed control in a Roundup ReadyÒ soybean system. To control taller weeds such as heavy henbit, marestail, dandelion and kochia, apply Rage D-Tech at a rate of 0.75 pt/A. For in-crop applications in corn, sorghum, range grasses, and small grains, use 0.5 - 1.0 pt/A of Rage D-Tech to achieve maximum desiccation of weeds ranging in height from eight to 12 inches or taller.

Rage D-Tech is an excellent tank-mix partner, providing fast burndown of both broadleaves and grasses to save time and money. University extension representatives recommend using a combination of glyphosate and other herbicides to combat problem weeds and establish an effective weed management program. Rage D-Tech can easily transition into a rotational cropping system as part of an overall long-term management program in corn and soybeans.
