HERBICIDAL CONCENTRATE COMPOSITIONS CONTAINING GLYPHOSATE AND DICAMBA SALTS

摘要

The mixture of potassium or certain amine salts of glyphosate and dicamba allows the preparation of high-strength liquid compositions containing greater than 300 gae/L of total active ingredient loading if the pH is adjusted between about 6.0 and about 8.0. Compositions are particularly well-suited for herbicidal applications on crops that are resistant or tolerant to both glyphosate and dicamba.

主权项

1. A homogeneous, stable, high-strength aqueous herbicidal concentrate composition comprising:
(a) water, (b) a glyphosate potassium or amine salt, and (c) a dicamba potassium or amine salt,in which (i) the glyphosate salt is potassium or a secondary, tertiary or quaternary alkylamine or a primary, secondary, tertiary or quaternary alkanolamine, alkylalkanolamine or alkoxyalkanolamine salt, wherein the alkyl and alkanol groups are saturated and contain from C1-C4 carbon atoms individually, (ii) the dicamba salt is potassium or a secondary, tertiary or quaternary alkylamine or a primary, secondary, tertiary or quaternary alkanolamine, alkylalkanolamine or alkoxyalkanolamine salt, wherein the alkyl and alkanol groups are saturated and contain from C1-C4 carbon atoms individually, (iii) the composition contains a total active ingredient loading of at least 300 gae/L of the glyphosate potassium or amine salt and the dicamba potassium or amine salt, (iv) the acid equivalent weight ratio of the glyphosate potassium or amine salt to the dicamba potassium or amine salt is from about 1:1 to about 3:1, and (v) the pH is from about 6.0 to about 8.0.
