Changes in Roundup Herbicide 

In 1996, Monsanto will release a "full load" formulation called Roundup Ultra 
and Roundup Ultra RT. It contains a complete adjuvant base and additional 
surfactants are not allowed according to label instructions. The label will 
state: DO NOT add surfactants, pH buffers or acidifiers... Only two 
exceptions will be allowed for adding ammonium sulfate: 1) When using hard 
water above 500 ppm hardness, add ammonium sulfate or an additional 4 fl oz 
of product, and 2) during cold temperatures or moisture stress, add ammonium 
sulfate or an additional 2 fl oz of product. 

Roundup Ultra and Ultra RT formulations will prevent companies that market 
adjuvants from allowing their products to be used. Roundup Ultra and Roundup 
Ultra RT will have a "Caution" signal word instead of "Warning" as with 
Roundup and Roundup RT. The price of the Ultra formulation may be 
approximately $3/gal more than the original products. For example, if Roundup 
cost $50/gal Roundup Ultra will be $53/gal and if Roundup RT cost $43/gal, 
then Roundup Ultra RT will cost $46/gal. The Ultra labels will be written 
exactly the same as the regular Roundup labels. As the glyphosate patent 
nears termination, this may be an attempt to put the best formulation of 
glyphosate on the market before other generics enter. A "full load" Roundup 
has already been introduced into the turf and ornamental market. It is called 
"Roundup Pro." 

Generic formulations of Roundup will be sold until supplies are depleted. 
These include Honcho, Rascal, Rattler, Silouette, etc. The only other form of 
Roundup that will continue to be available for ag use is Glyphos which is 
sold by Cheminova, a European based company. It is indentical to Roundup, not 
Roundup Ultra, with the same 3 lb ae/gal formulation. 

***NOTE*** Some evidence exists that Roundup applied to stubble and plant 
           residue after a no-till crop has been planted may have 
           preemergence activity and suppress crop germination and early 
           growth. This has been observed only in wet conditions after 
           application.
