Abstract
Compounds formed by combining a carboxylic acid herbicide with N—((C1-C16)alkyl or arylalkyl) tri((C1-C16)alkyl)ammonium hydroxide have herbicidal activity on an acid equivalent basis at least as active as the commercially used carboxylic acid herbicide salts, but are less volatile.
Claims8
An herbicidal compound comprising the reaction product of an herbicidal carboxylic acid selected from 2,4-D, triclopyr, aminopyralid, clopyralid, fluroxypyr, picloram, cyhalofop, fluazifop, haloxyfop, clodinafop, fenoxaprop, dicamba, glufosinate, and glyphosate and a (tetraalkyl) ammonium hydroxide of the formula
- wherein R1, R2 and R3 independently represents (C1-C16) alkyl or any two of R1, R2 and R3 may join to form a ring represented by —(CH2)n— where n is an integer from 3-5 and R4 represents ((C2-C4) alkyl or arylalkyl.
An herbicidal compound comprising the reaction product of choline hydroxide and 2,4-D, triclopyr, or dicamba.
