ST. LOUIS, Mo., Sept. 12, 2007 - Dry weather and insect pressure can severely stress corn plants, undermining plant health and reducing yield potential. A series of 22 stress mitigation plots being monitored across the Corn Belt this season by Monsanto are illustrating those effects.

At these locations, a 40-by-66-foot tent has been erected over 24 rows of corn to prevent the plants from receiving rain. The tents have a clear vinyl top so the plants can receive sunlight.

The stress-mitigation test plots are being monitored this season at research facilities in Nebraska, Missouri, Illinois, Indiana, Iowa, Minnesota, Kansas, Colorado, Texas, South Dakota and Ohio.

Decatur, Ill., August 28, 2007 - DEKALB® has introduced its 2008 class of 41 new YieldMaker(tm) products, all of which have been developed from a broad, industry-leading germplasm pool and tested under local growing conditions. The 2008 lineup includes products developed for improved weed control and season-long insect protection.

“Our new YieldMaker corn products contain exclusive genetics and a wide range of traits with greater standability, yield potential and drydown capabilities,” says Bob Starke, Ph.D, U.S. Corn Product Manager for Monsanto. “Our 2008 lineup is state of the art, and we have the numbers from extensive research and field trials to back up this claim.”

13,475 DEKALB and third-party in-field comparisons showed that DEKALB YieldMaker corn products outyielded competitive products by an average of 9.2 bushels per acre.2

These same field comparisons also showed that DEKALB YieldMaker corn products were on average 0.5 percent drier at harvest than competitive products. “Together, the yield and drydown advantages of DEKALB corn delivered an average profit advantage of $28.21 per acre compared with competitive products2,” Starke says.

Along with high-performing germplasm, YieldMaker corn products offer growers a wide selection of built-in traits, allowing growers to select the specific trait or trait combinations best suited for their field conditions and management practices. Such traits include Roundup Ready® 2

technology, YieldGard VT(tm), YieldGard® Corn Borer, YieldGard Rootworm and YieldGard Plus, which offers protection against corn rootworms, corn borers and secondary insect pests.

DES MOINES, Iowa, Sept. 7, 2007 - Growers looking for more bushels per acre and more ethanol per bushel can select from 21 new Pioneer® brand High Total Fermentable (HTF) ethanol hybrids for 2008 planting.

Hybrids from Pioneer Hi-Bred, a DuPont business, with above-average ethanol yield potential are designated as HTF ethanol hybrids. These hybrids deliver higher levels of fermentable starch, resulting in higher ethanol output. Currently, Pioneer has more than 180 HTF-designated hybrids available across a wide range of maturities.

“Research shows there can be up to 7 percent variation in ethanol yield potential among different hybrids,” says Russ Sanders, Pioneer end-use marketing director. “Pioneer research has shown that the HTF trait is a more accurate indicator of dry-grind ethanol production than total starch or extractable starch.”

The HTF designation is assigned to elite Pioneer hybrids based on data from more than 21,600 Pioneer plot samples over the past five years. More than 30 locations and 165 hybrids were sampled.

In addition, many Pioneer HTF ethanol hybrids contain the Herculex® I or Herculex XTRA insect protection traits which reduce insect damage to grain and prevent molds and mycotoxins. This helps maximize grain yields and ensures a more consistent supply of high-quality grain.

Dry-grind ethanol production

The Pioneer HTF hybrid screening program has shown that some hybrids are clearly superior in the amount of ethanol produced per bushel of grain. Pioneer is leading the industry in developing analytical tools for determining ethanol yield of grain, identifying hybrids with the highest ethanol potential and developing new hybrids with desirable grain traits for dry-grind ethanol production.

In the dry-grind ethanol industry, the cost of corn makes up more than 60 percent of the total production cost. It is essential, therefore, to get the most for every dollar spent purchasing corn.

“As the dry-grind industry grows, Pioneer will continue to provide growers and processors with the hybrids and information needed to maximize ethanol yields,” says Sanders.

St. Louis, Mo., (July 25, 2007) – A new resource for farmers, farm dealers and consultants that provides detailed agronomic information related to corn and soybean production is now available free of charge via a series of publications and a special Web site offered by DEKALB® corn and Asgrow® soybeans.

Titled Growing Knowledge®, the resource offers written timely, technical information that farmers can use to help improve management systems, crop yield and profitability. Three different publications, a Growing Knowledge Newsletter, Agronomic ALERTS and Agronomic SPOTLIGHTS, present localized and regionalized information in varying degrees of urgency. All three publications can be accessed at www.monsantoperformance.com by selecting the page for your home area.

Published monthly, the Growing Knowledge newsletter addresses agronomic issues across a variety of cropping systems, with primary focus on corn and soybeans. The Growing Knowledge Agronomic SPOTLIGHT publications are used to convey important information between newsletter issues. The Growing Knowledge ALERTS are used to rapidly convey critical status information to farmers in any given target region.

“For example, an area hit by a hailstorm can expect a Growing Knowledge ALERT within a very short period of time to address the problem and provide tools to manage the problem,” says Tony White, Ph.D., Agronomic Information Manager for Monsanto Company. “Other ALERTS might address topics such as purple corn, environmental factors that must be managed or information on insect migrations and infestations.”

According to White, these Growing Knowledge resources are currently available to farmers in 10 Corn Belt states and the eastern half of Canada. The states include Indiana, Illinois, Wisconsin, Minnesota, Iowa, Nebraska, Kansas, Oklahoma, Missouri and the Texas Panhandle. For Asgrow and DEKALB customers in Quebec, all agronomic information is available in French. There are plans under way to expand the Growing Knowledge portfolio to 23 Corn Belt states and all of Canada in late 2007 with introduction of the concept into the southern and western states during 2008.

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.
