Abstract

An adjuvant additive includes a first active substance, water, and a surfactant comprising a carboxylated alcohol alkoxylate of the general formula (I). An agrochemical composition includes the adjuvant additive and a second active substance in addition to the first active substance in the adjuvant additive.

First claim

1 . An adjuvant additive for an agrochemical composition, said adjuvant additive comprising:
A) a first active substance; B) water; and C) a surfactant comprising a carboxylated alcohol alkoxylate of the general formula (I):

wherein R is hydrocarbon group having from 4 to 14 carbon atoms; R 1 is selected from the group of a hydrogen atom, an alkyl group, and an aryl group; each A is independently selected from an alkyleneoxy group having from 2 to 4 carbon atoms; m has a value of from 20 to 35; and each B is independently of the general formula (II):

wherein each R 2 is independently selected from the group of a hydrogen atom, an alkyl group, and a salt of a carboxyl group, and n has a value of from 6 to 20; and
wherein at least one R 2 is a salt of a carboxyl group.

2 . An adjuvant additive as set forth in claim 1 wherein said first active substance is present in an amount of greater than 10 and less than 30% by weight based on the total weight of said adjuvant additive.

3 . An adjuvant additive as set forth in claim 1 wherein said first active substance is a nitrogenous fertilizer selected from the group of ammonia solutions, ammonium salts, urea, thiourea, and combinations thereof.

4 . An adjuvant additive as set forth in claim 3 wherein said nitrogenous fertilizer is ammonium sulfate.

5 . An adjuvant additive as set forth in claim 1 wherein said carboxylated alcohol alkoxylate is present in an amount of from 1 to 20% by weight based on the total weight of said adjuvant additive.

6 . An adjuvant additive as set forth in claim 1 wherein said salt of said carboxyl group is further defined as a salt of a dicarboxylic group.

7 . An adjuvant additive as set forth in claim 1 wherein said carboxylated alcohol alkoxylate is of the general formula (III):

wherein R, R 1 , A, m, and n are the same as defined above; each R 3 is independently selected from the group of a hydrogen atom and a methyl group; and each R 4 is independently selected from the group of a hydrogen atom and a salt of a dicarboxylic group of the general formula (IV):

wherein at least one R 4 is represented by a salt of a dicarboxylic group of the general formula (IV).

8 . An adjuvant additive as set forth in claim 1 wherein m is of from 24 to 28 and n is of from 6 to 10.

9 . An adjuvant additive as set forth in claim 1 further comprising a viscosity modifier selected from the group of high fructose corn syrup and honey and present in an amount of from 10 to 30% by weight based on the total weight of said adjuvant additive.

10 . An adjuvant additive as set forth in claim 1 further comprising a pH buffer selected from the group of NaOH, KOH, and NH 4 OH.

11 . An adjuvant additive as set forth in claim 1 that has a foam height of less than or equal to 20 mm measured at 10 seconds in accordance with F-106 Persistent Foaming Method.

12 . An adjuvant additive as set forth in claim 1 that remains homogenous at a temperature of 20° Celsius for a period of at least 3 days.

13 . An agrochemical composition for treating plants, said agrochemical composition comprising:
i) an adjuvant additive comprising;
A) a first active substance,
B) water, and
C) a surfactant comprising a carboxylated alcohol alkoxylate of the general formula (I):

wherein R is hydrocarbon group having from 4 to 14 carbon atoms; R 1 is selected from the group of a hydrogen atom, an alkyl group, and an aryl group; each A is independently selected from an alkyleneoxy group having from 2 to 4 carbon atoms; m has a value of from 20 to 35; and each B is independently of the general formula (II):

wherein each R 2 is independently selected from the group of a hydrogen atom, an alkyl group, and a salt of a carboxyl group, and n has a value of from 6 to 20; and
wherein at least one R 2 is a salt of a carboxyl group; and
ii) a second active substance different from said first active substance.

14 . An agrochemical composition as set forth in claim 13 wherein said second active substance is selected from the group of acetyl-CoA carboxylase inhibitors, acetolactate synthase inhibitors, amides, auxin herbicides, auxin transport inhibitors, carotinoid biosynthesis inhibitors, enolpyruvylshikimate-3-phosphate synthase inhibitors, glutamine synthetase inhibitors, lipid biosynthesis inhibitors, mitosis inhibitors, protoporphyrinogen IX oxidase inhibitors, photosynthesis inhibitors, synergists, growth substances, cell wall synthesis inhibitors, and combinations thereof.

15 . An agrochemical composition as set forth in claim 13 wherein said adjuvant additive is present in an amount of greater than 0 but less than 10% by weight based on the total weight of said agrochemical composition.

16 . An agrochemical composition as set forth in claim 13 wherein said first active substance is a nitrogenous fertilizer selected from the group of ammonia solutions, ammonium salts, urea, thiourea, and combinations thereof, and is present in an amount of greater than 10 and less than 30% by weight based on the total weight of said adjuvant additive.

17 . An agrochemical composition as set forth in claim 13 wherein said carboxylated alcohol alkoxylate is present in an amount of from 1 to 20% by weight based on the total weight of said adjuvant additive.

18 . An agrochemical composition as set forth in claim 13 wherein said carboxylated alcohol alkoxylate is of the general formula (III):

wherein R, R 1 , A, m, and n are the same as defined above; each R 3 is independently selected from the group of a hydrogen atom and a methyl group; and each R 4 is independently selected from the group of a hydrogen atom and a salt of a dicarboxylic group of the general formula (IV):

wherein at least one R 4 is represented by a salt of a dicarboxylic group of the general formula (IV).

19 . An agrochemical composition as set forth in claim 13 wherein m is of from 24 to 28 and n is of from 6 to 10.

20 . An agrochemical composition as set forth in claim 13 that remains homogenous at a temperature of 20° Celsius for a period of at least 3 days.
