Compounds derived from herbicidal carboxylic acids and tetraalkylammonium or (arylalkyl) trialkylammonium hydroxides
View Patent ↗Compounds formed by combining a carboxylic acid herbicide with N—((C 1 -C 16 )alkyl or arylalkyl) tri((C 1 -C 16 )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.
1. 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 R 1 , R 2 and R 3 independently represents (C 1 -C 16 ) alkyl or any two of R 1 , R 2 and R 3 may join to form a ring represented by —(CH 2 ) n — where n is an integer from 3-5 and R 4 represents ((C 2 -C 4 ) alkyl or arylalkyl.
2. An herbicidal compound of claim 1 in which the herbicidal carboxylic acid is 2,4-D, triclopyr, or dicamba.
3. An herbicidal composition comprising an herbicidally effective amount of a compound, as claimed in claim 1 , or mixtures thereof, in admixture with an agriculturally acceptable adjuvant or carrier.
4. An herbicidal compound comprising the reaction product of choline hydroxide and 2,4-D, triclopyr, or dicamba.
5. An herbicidal compound of claim 4 in which the herbicidal carboxylic acid is triclopyr.
6. An herbicidal compound of claim 4 in which the herbicidal carboxylic acid is dicamba.
7. An herbicidal composition comprising an herbicidally effective amount of a compound, as claimed in claim 4 , or mixtures thereof, in admixture with an agriculturally acceptable adjuvant or carrier.
8. An herbicidal compound of claim 4 in which the herbicidal carboxylic acid is 2,4-D.
