INDIANAPOLIS — July 30, 2007 — The biggest piece of news at the largest farm show in the Midwest could likely come at the corner of 10th Progress Street and Central Progress Avenue. That’s where

Dow AgroSciences will reveal for the first time and announce details of an exciting, new family of herbicide tolerance traits during the Farm Progress Show on Aug. 28 through 30 in Decatur, Ill.

Known currently as Dow AgroSciences Herbicide Tolerance (DHT), this innovative technology will improve and enhance the performance of glyphosate and glufosinate cropping systems, says Dan Kittle, vice president of Research & Development at Dow AgroSciences.

“DHT traits will enable the use of additional broad-spectrum herbicides with differing modes of action in both the burndown and postemergence application timings,” Kittle says. “These technologies will provide solutions to improve the control of hard-to-kill broadleaf weeds, reduce selection pressure for glyphosate resistance and help to sustain the use of the glyphosate tolerance cropping system in crops like corn, soybeans and cotton.”

Visitors to the Dow AgroSciences tent at Lot 1030 will be able to get a backstage, up-close look at corn containing DHT technology in field plots. They also will get more details of the chemistries that can be

applied postemergence over the top of crops containing DHT.

“One of the most exciting things about this new technology is that it will provide tolerance to multiple families of chemistry,” says Ben Kaehler, Traits & Germplasm Licensing business leader for

Dow AgroSciences. “DHT will complement today’s existing herbicide tolerance traits to deliver improved weed control above and beyond that obtained with glyphosate or glufosinate alone.”

Besides DHT, visitors will see several new herbicides being launched by the company through its new Technology for Traits™ portfolio of products designed for use in herbicide-tolerant crops:

- SureStart™ herbicide is a broad-spectrum, soil-applied herbicide that has been designed and labeled for use only in herbicide-tolerant corn, such as Roundup Ready® corn.

- Durango® DMA® herbicide contains a new third-generation glyphosate salt that delivers ease of handling and consistent, proven, broad-spectrum weed control.

- Sonic™ herbicide contains two unique modes of action for broad-spectrum foundation control of broadleaf weeds in Roundup Ready soybeans.

Also on display in Dow AgroSciences field plots will be the latest hybrids from Mycogen Seeds, including both grain corn and Silage-Specific™ hybrids; HERCULEX® XTRA Insect Protection technology; and the company’s industry-leading healthier oils lineup.

Data Shows This Next-Generation Technology Will Deliver A 7 To 11 Percent Yield Advantage For Soybean Farmers

ST. LOUIS (July 31, 2007) - Roundup RReady2Yield(tm) soybean, a next generation of Roundup Ready® soybean with an improved yield benefit, has completed the regulatory process in the United States and Canada, Monsanto Company announced today. The U.S. Department of Agriculture and Health Canada and the Canadian Food Inspection Agency have all granted approvals, completing the final step in each country’s regulatory process. These approvals mark an important step forward bringing this next-generation technology one step closer to farmers’ fields.

Although approvals to plant the improved soybean seeds have been granted, Monsanto, in keeping with its stewardship pledge, does not intend to commercialize the product until key soybean importing countries with functioning regulatory systems have granted import approvals. Monsanto has submitted regulatory filings and is currently awaiting approvals from key soybean export markets. The company anticipates a commercial launch prior to the end of the decade, once appropriate import authorizations are obtained.

“We are always looking for new products that provide value and benefit to growers, and we eagerly anticipate bringing a substantial yield benefit to the Roundup Ready system that growers have embraced over the past 11 years,” said Ernesto Fajardo, Vice President of U.S. Crop Production for Monsanto. “In addition to the simple, dependable, flexible and reliable weed control and crop safety benefits provided by the Roundup Ready system, growers will be able to improve their bottom line by producing more bushels per acre.”

Three years of field comparisons have demonstrated that Roundup RReady2Yield soybeans show a 7 to 11 percent yield advantage over a comparable first-generation Roundup Ready line. In addition, data collected during the first year of large-scale breeding comparisons representing more than 15,000 lines and hundreds of genetic backgrounds showed performance of Roundup RReady2Yield soybean lines within the 7 to 11 percent range of increase over comparable Roundup Ready lines in the same development phase. This improved product produces the same protein that has allowed soybean growers to use Roundup® agricultural herbicides over the top of their Roundup Ready soybeans and will continue to provide the simple, dependable and flexible weed control and crop safety that growers expect from Monsanto’s Roundup Ready system.

Roundup RReady2Yield soybeans represent an important base from which Monsanto will introduce its portfolio of next-generation technologies in soybeans - including dicamba tolerant and intrinsic yield soybeans. Monsanto’s research in both breeding and biotechnology, including technologies like Roundup RReady2Yield, highlights one way the company is supporting U.S. farmers as they meet the world’s growing demand for food, feed and fuel.

Monsanto Company is a leading global provider of technology-based solutions and agricultural products that improve farm productivity and food quality. Over the last two decades, Monsanto scientists have focused on researching and delivering meaningful products to our farmer customers and the broader soybean value chain. Monsanto invests more than $700 million annually to identify and develop new solutions for growers. For more information, please visit http://www.monsanto.com.

Request nutrient profile when evaluating potential value of product

DES MOINES, Iowa, August 1, 2007 - The rapid expansion of the ethanol industry has greatly increased the volume of distiller’s grains available for livestock feed. Nutritionists with Pioneer Hi-Bred suggest feeding distiller’s grains for high protein and fat values, but keeping a close eye on sulfur and phosphorous content in grain.

“The industry is reporting that 75 percent to 80 percent of the distiller co-products are fed to dairy and beef cattle,” says Steve Soderlund, Pioneer beef nutrition manager. “When evaluating the potential value of these products, make sure you request a nutrient profile from the plant. Consider how these products complement your existing feeding program.”

Soderlund adds that one of the biggest factors in determining the nutrient content of the distiller co-products is the grain source used by the ethanol plant.

“In comparison to corn, if the plant is using sorghum as a primary grain source, expect to see higher protein levels, but a lower fat level,” says Soderlund.

Feeding distiller’s grains

University beef cattle feeding trials have found the energy values of distiller’s grain can be as much as 9 percent better than corn. Soderlund says this is due primarily to the fat content in the product which is 2.25 to 2.5 times the caloric density of starch. Most distiller’s grains contain between 10 percent to 12 percent fat and 24 percent to 30 percent protein.

“Including distiller’s grains at 15 percent to 20 percent of the dry matter in a beef finishing ration generally will meet the protein requirements and contribute to the energy needs of the cattle,” says Soderlund. “In forage-based diets for beef cows, distiller’s grains can be used as a source of supplemental protein and energy. The amount fed depends on the desired performance and nutrient content of the forage.”

Be aware of two potential mineral concerns, sulfur and phosphorus, when feeding distiller’s grains to feedlot cattle. Keep sulfur content to less than 0.4 percent of the dry matter intake from all sources, including water. Polioencephlemalacia - a disease affecting the central nervous system of cattle - can result from elevated sulfur levels. In addition, phosphorous levels should be monitored. The phosphorous content typically will be three times higher in distiller grains than in corn grain.

“Unless very high levels of calcium are supplemented, an unfavorable calcium-to-phosphorous ratio may develop,” says Soderlund. “Urinary calculi - water belly - can develop in feedlot steers under these conditions. Keep the calcium-to-phosphorous ratio between 1-1 to 1.5-1.”

Distiller’s grains will be used primarily as a protein and fat source in dairy rations, which generally limits its inclusion rate to less than 10 percent of the diet. However, university tests have shown that distiller grains can be fed at up to 20 percent of the ration when feeding higher forage levels.

“Dairy producers need to pay close attention to the amount of effective fiber in the diet,” notes Soderlund. “Even though distiller grains contain a relatively high level of neutral detergent fiber, the fiber is very fine and will not maintain good rumination.”

Traditional ethanol co-products

There are several different distiller feed products produced by the ethanol industry. The highest-volume product is distiller’s grains, which primarily contains unfermented grain residues - protein, fiber and fat. The remaining fraction is called thin stillage which contains yeast cells, soluble nutrients and very small corn particles.

“Most large distilleries have the capability to dry their distiller’s grains - DDG,” says Soderlund. “The thin stillage is concentrated to a molasses-like consistency to form condensed distiller’s solubles (CDS). The CDS product can be sold directly to liquid feed manufacturers or dried and placed back on the DDG to produce distiller’s grains plus soluble (DDGS).”

While the majority of distiller’s grain produced in the upper Midwest is sold as DDGS, a high percentage produced in the High Plains is fed as wet distiller’s grain (WDG) locally - reducing energy costs associated with drying. WDG needs to be fed within four to five days before warm weather causes significant spoilage.

Future co-products

Pioneer is developing genetics that not only yield higher ethanol but also produce co-products with higher nutritional value. Strategies to improve the amino acid profile, lower fiber content, lower phosphorus content and improve fatty acid profiles are all being explored.
