You'll have a glyphosate herbicide option for your Roundup Ready soybeans for the first time in 1999.

Monsanto and Cheminova, a Denmark-based company with operations in the U.S., have reached an agreement that will allow Cheminova to sell its product, Glyfos, for use on Roundup Ready soybeans this year.

Cheminova has sold Glyfos in the U.S. since 1994 under previous supply agreements with Monsanto. In addition to soybeans in 1999, Glyfos will be available for use on Roundup Ready cotton in 2000 and Roundup Ready corn in 2001.

The license and supply agreement between the two companies is one of many Monsanto has announced recently.

As a result, the availability of glyphosate, the active ingredient in Monsanto's line of Roundup products, will increase substantially in the next few years.

With marketing agreements beginning to kick in this year, here's a quick look at companies and their glyphosate deals with Monsanto.

* Dow AgroSciences has reached an agreement with Monsanto to make and market its own glyphosate product outside the U.S. in 1999, with some restrictions. The agreement also allows Dow to begin marketing its own glyphosate product in 2000 for Roundup Ready soybeans and cotton in this country. In 2001, its product will be available for Roundup Ready corn.

* Micro Flo will be allowed to register its own brand of glyphosate herbicide for sale in the U.S. It will be available for use on Roundup Ready soybeans and cotton in 2000, and on Roundup Ready corn in 2001. Micro Flo, a subsidiary of BASF, specializes in post-patent products.

* Nufarm, an Australia-based company, also will have a glyphosate herbicide, Credit, in the U.S. market next year. Credit will be sold for use on Roundup Ready soybeans and cotton in 2000 and for Roundup Ready corn in 2001.

"Monsanto's Roundup and Roundup Ultra herbicides will compete with the glyphosate herbicide brands of these other companies," says Lisa Drake, Monsanto's director for public affairs. "All performance, crop safety and stewardship support concerning all uses of other brands of glyphosate herbicides, including over the top of pertinent Roundup Ready crops, is the responsibility of the company marketing the product."

* Novartis, in a different type of licensing agreement, will be allowed to formulate herbicide premixes using glyphosate and Novartis herbicides starting in 2001. The company can begin selling the premixes for use over the top of Roundup Ready corn and soybeans that year.

"Some growers have told us they want an even wider selection of weed management solutions for Roundup Ready corn and soybeans, and this agreement provides additional options for growers," says Kerry Preete, Monsanto's global product strategy director for glyphosate products.

More licensing agreements are likely to be announced before Monsanto's patent on glyphosate runs out at the end of 2000.
