## Abstract

This invention provides a dry pulverulent composition which is comprised of (1) a particulated agrochemical ingredient such as a herbicide; and (2) an inorganic salt ingredient such as sodium, potassium or ammonium bicarbonate or a mixture thereof, which is adsorbed on the surface of the agrochemical particles. The agrochemical ingredient can be a mixture of two or more biologically active organic compounds. The adsorbed inorganic salt ingredient also can be in a blend with a water-soluble or water-dispersible organic polymer ingredient as a film coating, and the coating of ingredients can function as a slow-release medium in the presence of moisture.

## Claims

### Claim 1

A dry pulverulent composition which has a combination of ingredients comprising (1) a particulated fungicidal ingredient wherein the average particle size diameter is in the range between about 10-600 microns; (2) a fungicidal inorganic salt ingredient selected from the group consisting of alkali metal bicarbonates, ammonium bicarbonate and mixtures thereof, which is adsorbed on the surface of the particulated fungitidal ingredient; and (3) a compatibility enhancing ingredient selected from the group consisting of water-soluble organic . compounds which are in solid form at a temperature below about 10.degree. C.

### Claim 2 (depends on 1)

A composition in accordance with claim 1 wherein the compatibility enhancing ingredient is a monohydroxy or polyhydroxy compound, and the quantity of compatibility enhancing

### Claim 3

A slow-release pulverulent composition which has a combination of ingredients comprising (1) a particulated fungicidal ingredient wherein the average particle size diameter is in the range between about 10-600 microns; (2) a blend ingredient comprising (a) a fungicidal inorganic salt ingredient selected from the group consisting of alkali metal bicarbonates, ammonium. bicarbonate and mixtures thereof, and (b) a water-soluble or water-dispersible organic polymer; wherein the blend ingredient is adsorbed on the surface of the particulated fungicidal ingredient, and the blend ingredient

### Claim 4 (depends on 3)

A composition in accordance with claim 3 wherein the organic polymer in the blend ingredient is a polyhydroxy or polyoxyalkylene polymer.

### Claim 5 (depends on 1, 3)

A composition in accordance with claims 1 or 3 wherein the particulated fungicidal ingredient is benomyl.
