Prowl H₂O: A New Prowl Formulation

May 10, 2004

A new formulation of Prowl herbicide is being marketed in the sugarcane growing areas.  The new formulation, Prowl H₂O, is water based as compared with the Prowl EC (emulsifiable concentrate) formulation which is oil based.  For the EC formulation an emulsifier is added that allows the herbicide to be mixed with water without separating out.  In contrast, the new formulation is micro-encapsulated where the herbicide is coated with a polymer.

Envoke: A New Herbicide for Sugarcane

March 18, 2004

A major component of our weed research program in the LSU AgCenter involves the evaluation of new herbicides in development by chemical companies.  Envoke, common name trifloxysulfuron-sodium, is in the sulfonylurea chemical family and has a unique mode of action unlike any other herbicide currently used in sugarcane.  Research in Louisiana with Envoke (formerly CGA 362622) was first initiated in 1999.  Provided in this article is information related to Envoke, which was labeled for use in sugarcane in 2004.

It’s Time to Think About Winter Weeds and Bermudagrass

January 13, 2004

Weed pressure in sugarcane fields right now in mid-January ranges from nothing to a mat of green vegetation completely covering the rows.  In most cases weed pressure is greatest in fields where sugarcane residue was burned early in the season and in plant cane where herbicides just ran out.  In fields where sugarcane residue is still present it is doing a good job of suppressing weed emergence.  This positive attribute of crop residue, however, also can be negative when considering the crop.  Research conducted by USDA researchers in Houma over several years clearly shows that a sugarcane yield reduction of 4 to 5 tons per acre can occur if crop residue is not removed.  If you have fields right now that can be burned then do so as soon as possible, preferably by mid February.  In fields where winter weeds are present take a close look to see exactly what you have.
