摘要：
Disclosed herein is a homogeneous, stable, high-strength aqueous herbicidal concentrate composition comprising: (a) water, (b) a glyphosate potassium or amine salt, preferably a monoethanolamine, dimethylethanolamine, dimethylamine, diglycolamine or choline salt, and (c) a dicamba potassium or amine salt, such as dimethyl amine , monoethanolamine, dimethylethanolamine, choline or diglycolamine 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 Cr 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 1:1 to 3:1, and (v) the pH is from 6.0 to 8.0. Optionally further comprising a least one cosolvent in amounts between 20 g/L and 200 g/l, ate least one efficacy enhancing surfactant in amounts between 20 g/L and 200 g/L, and a second auxin type herbicide including chlorophenoxy acids such as 2,4-dichlorophenoxy acetic acid [2,4-D], 2,4-dichlorophenoxy butyric acid [2,4-DB], (4-chloro-2-methylphenoxy)acetic acid [MCPA] or 4-(4-chloro-2- methylphenoxy)butanoic acid [MCPB]； pyridine carboxylic acids such as picloram, aminopyralid, fluroxypyr, clopyralid or triclopyr； or quinoline carboxylic acids such as quinmerac or quinclorac.
