example 1

[0112] The effect of glyphosate, 2,4-D, combinations of 2,4-D and glyphosate and combinations of all of the above with oxalic acid on velvetleaf was tested. Aqueous concentrate compositions were prepared containing potassium glyphosate salt, reported in g a.e. / liter, and excipient ingredients as shown in Table 1a. The 806DOT, 806E7S, 806F4Q and 806G3B formulations contained 62 grams acid equivalent per liter. Formulations 806A2D, 806B9H, 806C5Z, 806F4Q and 806G3B contained the IPA salt of 2,4-D measured in grams acid equivalent per liter.

Abstract

Herbicidal compositions are provided which cause rapid symptomology while delivering long term control of regrowth of plants. The herbicidal concentrate compositions comprise N-phosphonomethylglycine or a herbicidal derivative thereof, an auxin herbicide or a herbicidal derivative thereof, and at least one surfactant. Also provided is a method for killing or controlling the growth of certain plants by contacting the foliage of the plants with the diluted concentrate composition.

Description

REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application Ser. No. 60 / 552,065, filed Mar. 10, 2004, the entire contents of which are incorporated herein by reference.BACKGROUND [0002] The present invention relates generally to herbicidal compositions or formulations, and to methods of using such compositions to kill or control the growth and proliferation of unwanted plants. In particular, the present invention relates to herbicidal compositions, as well as their methods of use, which comprise N-phosphonomethylglycine (glyphosate), or a herbicidal derivative thereof, and an auxin herbicide, or a herbicidal derivative thereof, optionally with one or more suitable surfactants. Such compositions cause early visual symptoms of treatment and / or enhanced effectiveness or control when applied to the foliage of plants. [0003] Glyphosate is well known in the art as an effective post-emergent foliar-applied herbicide. In its acid form, glypho...
