- A01N 25/26: in coated particulate form
- A01N: PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toiletry purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS

## Abstract

A granular pesticidal composition in which a powdery pesticide is aggregated and coated with a thermosetting resin is capable of enabling a pesticidal active ingredient to be controlled-released. Further, the controlled-release pesticidal granule can be produced by mixing a powdery pesticide with a first liquid component serving as a raw material for a thermosetting resin, a process of adding a second liquid component serving as a raw material for a thermosetting resin, and then making the first liquid component react with the second liquid component to produce a thermosetting resin.

## Claims

### Claim 1

A method for producing a pesticidal composition comprising
a process of mixing a powdery pesticide with a first liquid component serving as a raw material for a thermosetting resin,
a process of adding a second liquid component serving as a raw material for a thermosetting resin, and then
making the first liquid component react with the second liquid component to produce a thermosetting resin.

### Claim 2 (depends on 1)

The method for producing a pesticidal composition according to claim 1, which comprises a process of mixing a powdery pesticide with a first liquid component serving as a raw material for a thermosetting resin, a process of adding a second liquid component serving as a raw material for a thermosetting resin, obtaining a pesticidal granule by making the first liquid component react with the second liquid component to produce a thermosetting resin, a process of adding to the resultant pesticidal granule the first liquid component and the second liquid component simultaneously or sequentially, and then making them react for coating of the pesticidal granule with the thermosetting resin.

### Claim 3 (depends on 1)

The method for producing a pesticidal composition according to claim 1, wherein the powdery pesticide is a powdery pesticide comprising 5-chloro-N-(1,3-dihydro-1,1,3-trimethyl-4-isobenzofuranyl)-1,3-dimethylpyrazole-4-carboxamide as a pesticidal active ingredient.

### Claim 4 (depends on 1)

The method for producing a pesticidal composition according to claim 1, wherein the powdery pesticide is a powdery pesticide comprising (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2-nitrovinylidenediamine as a pesticidal active ingredient.

### Claim 5 (depends on 1)

The method for producing a pesticidal composition according to claim 1, wherein the thermosetting resin is a urethane resin, urea resin or epoxy resin.

### Claim 6 (depends on 1)

The method for producing a pesticidal composition according to claim 1, wherein the thermosetting resin is a urethane resin.

### Claim 7 (depends on 6)

The method for producing a pesticidal composition according to claim 6, wherein the first liquid component is a polyol and the second liquid component is a polyisocyanate.

### Claim 8 (depends on 1)

The method for producing a pesticidal composition according to claim 1, wherein the thermosetting resin is an epoxy resin.

### Claim 9 (depends on 8)

The method for producing a pesticidal composition according to claim 8, wherein the first liquid component is a polyamine and the second liquid component is a polyglycidyl ether or polyglycidylamine.

### Claim 10 (depends on 1)

The method according to claim 1, wherein the powdery pesticide has an average particle size of 1 to 100 μm.

### Claim 11 (depends on 1)

The method according to claim 1, wherein the powdery pesticide has an average particle size of 1 to 30 μm.

### Claim 12 (depends on 1)

The method according to claim 1, wherein the method is carried out in the absence of a solvent.
