Abstract

The present disclosure provides an agricultural adjuvant composition comprising a substantially oil soluble micronutrient salt and an oil. The micronutrient is especially useful as a fertilizer. Accordingly, the adjuvant composition can be combined with a pesticide, for example a water soluble pesticide, to form an agrochemical formulation for application on and delivery of micronutrients to fertilize plants and for killing, inhibiting or repelling pests.

First claim

What is claimed is:

1 . An adjuvant composition comprising (a) a micronutrient salt obtained from the reaction of a metal-containing compound comprising boron, calcium, copper, iron, magnesium, manganese, molybdenum, nickel, selenium, zinc or a mixture thereof and an organic acid comprising a sulfonic acid, a carboxylic acid, a phosphorus acid, a boric acid or a mixture thereof and (b) an oil, wherein the organic acid comprises a number of carbon atoms to render the micronutrient salt that is formed substantially oil soluble.

2 . The adjuvant composition of claim 1 wherein the metal-containing compound comprises metal oxide, a metal carbonate, a metal hydroxide or a mixture thereof of boron, calcium, copper, iron, manganese, magnesium, molybdenum, nickel, selenium or zinc.

3 . The adjuvant composition of claim 2 , wherein the metal-containing compound is a metal oxide, a metal carbonate, a metal hydroxide or a mixture thereof of calcium, manganese, magnesium or zinc.

4 . The adjuvant composition of claim 2 , wherein the metal-containing compound is a metal oxide of calcium, manganese, magnesium or zinc.

5 . The adjuvant composition of claim 1 , wherein the organic acid is a sulfonic acid. represented by the general formula
R 1 SO 3 H or (R 1 ) x ArSO 3 H
where R 1 is a hydrocarbyl based group having less than 30 carbon atoms; x is an integer of 1 to 3; and, Ar is an aromatic hydrocarbon nucleus.

6 . The adjuvant composition of claim 1 , wherein the organic acid is a phosphorus acid selected from

wherein R 2 and R 3 are each, independently, an aliphatic, aromatic or non-aromatic alicyclic hydrocarbon or heterocyclic radical having from 1 to 30 carbon atoms.

7 . The adjuvant composition of claim 1 , wherein the oil comprises a vegetable oil, a mineral oil, a paraffin oil, a fatty acid ester or a mixture thereof.

8 . The adjuvant composition of claim 1 , further comprising a surfactant.

9 . The adjuvant composition of claim 1 , further comprising an auxiliary component.

10 . The adjuvant composition of claim 1 , wherein the adjuvant composition is substantially free of a chelate.

11 . An adjuvant composition comprising (a) 0.01% by weight to 20% by weight of a substantially oil soluble micronutrient salt obtained from the reaction of a metal-containing compound comprising boron, calcium, copper, iron, magnesium, manganese, molybdenum, nickel, selenium, zinc or a mixture thereof and an organic acid comprising a sulfonic acid, a carboxylic acid, a phosphorus acid, a boric acid or a mixture thereof and (b) 0.01% by weight to 45% by weight of an oil, where the % by weight is based on the total weight of the adjuvant composition.

12 . The adjuvant composition of claim 11 , wherein the metal-containing compound is a metal oxide of zinc or manganese.

13 . The adjuvant composition of claim 11 , wherein the organic acid has a number of carbon atoms ranging from 1 to 30.

14 . The adjuvant composition of claim 11 , further comprising (c) 0.1% by weight to 25% by weight of the surfactant, where the % by weight is based on the total weight of the adjuvant composition.

15 . The adjuvant composition of claim 14 , further comprising (d) 0.1% by weight to 90% by weight of an auxiliary component, where the % by weight is based on the total weight of the adjuvant composition.

16 . An agrochemical formulation comprising the adjuvant composition of claim 1 and a pesticide.

17 . The agrochemical formulation of claim 16 , wherein the pesticide is a water soluble herbicide.

18 . The agrochemical formulation of claim 17 , wherein the water soluble herbicide is selected from glyphosate, 2,4-D, dicamba and glufosinate.

19 . A method for killing, inhibiting or repelling a pest which includes contacting the agrochemical formulation of claim 16 and a pest.

20 . A container comprising the adjuvant composition of claim 1 .
