The present invention relates to an aqueous composition comprising at least an auxin herbicide and a drift control agent. It relates more particularly to a concentrated blend of at least one water-soluble salt of an auxin herbicide and of a drift control agent.
1 - 14 . (canceled)
15 . A pesticide composition comprising, by total weight of the composition:
a pesticide comprising at least one water-soluble salt of an auxin herbicide;
greater than about 0.5 wt % of a drift control agent comprising (a) at least one fatty deposition control agent that comprises one or more fatty acids, and (b) at least one surfactant.
16 . The composition of claim 15 , wherein the fatty acid used as the fatty deposition control agent is oleic acid, linoleic acid, erucic acid, docosenoic acid, docosahexenoic acid, tall oil fatty acid, a combination thereof, as well as salts thereof and mixtures of such acids and/or salts.
17 . The composition of claim 15 , wherein the fatty acid used as the fatty deposition control agent is oleic acid, linoleic acid, erucic acid, tall oil fatty acid, a combination thereof, salts thereof and/or mixtures of such acids and/or salts.
18 . The composition of claim 15 , wherein the fatty acid used as the fatty deposition control agent is tall oil fatty acid and/or salts thereof.
19 . The composition of claim 15 , wherein the composition comprises said drift control agent in an amount greater than 1% by weight of the composition, relative to the total weight of the composition.
20 . The composition of claim 15 , wherein the composition comprises greater than about 5 wt % of an aqueous liquid medium, relative to the total weight of the composition.
21 . The composition of claim 15 further comprising the presence of at least 300 g/L of water soluble salts.
22 . The composition of claim 15 , wherein the composition comprises at least 300 g/L a.e. of the at least one water-soluble salt of the auxin herbicide.
23 . The composition of claim 15 , wherein the pesticide comprises a dicamba salt, wherein the salt is N,N-bis(3-aminopropyl)methylamine, diethanolamine, monoethanolamine, dimethylamine, isopropylamine, dimethylethanolamine, diglycolamine, potassium, choline, or sodium.
24 . The composition of claim 15 , wherein the pesticide comprises dicamba diglycolamine salt or dicamba N,N-bis(3-aminopropyl)methylamine salt.
25 . The composition of claim 15 further comprising one or more surfactants.
26 . The composition of claim 15 , wherein the composition exhibits a viscosity of less than 10 Pa·s at a shear rate of greater than or equal to 10 s −1 .
27 . The composition of claim 15 , wherein the composition exhibits:
(a) a viscosity of greater than or equal to 5 Pa·s at a shear rate of less than 0.01 s −1 , and
(b) a viscosity of less than 5 Pa·s at a shear rate of greater than 10 s −1 .
28 . The composition of claim 15 , wherein the composition is free or substantially free of ammonium-containing water conditioning agent.
29 . The composition of claim 15 comprising from 5% by weight to 30% by weight of the drift control agent, relative to the total weight of the composition.
30 . The composition of claim 15 comprising from 10% by weight to 25% by weight of the drift control agent, relative to the total weight of the composition.
31 . The composition of claim 15 comprising from about 10 wt % to about 80 wt % of an aqueous liquid medium, relative to the total weight of the composition.
32 . The composition of claim 15 comprising from about 15 wt % to about 75 wt % of an aqueous liquid medium, relative to the total weight of the composition.
33 . The composition of claim 15 , wherein the composition is free or substantially free of ammonium sulfate.
