## Abstract

Provided is a method which exerts an excellent effect in controlling a pest in a field of soybean, corn or cotton, using a SDHI compound and a PPO-inhibiting compound. A method of controlling a pest (a weed and/or a plant pathogen) in a field of soybean, corn or a cotton, including treating a field before, at or after seeding with a seed of soybean, corn or cotton treated with one or more compounds selected from the group consisting of SDHI compounds, with one or more PPO-inhibiting compounds selected from the group consisting of flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen and a compound of the formula:

## Claims

### Claim 1

A method of controlling a weed in a field of soybean, comprising applying sulfentrazone to a field before, at or after seeding with a seed of soybean treated with penflufen.

### Claim 2

A method of controlling a weed in a field of soybean, comprising steps of:
treating a seed of soybean with penflufen, and
treating a field before, at or after seeding with the seed of soybean treated with the penflufen, with sulfentrazone.

### Claim 3 (depends on 2)

The method of controlling a weed according to claim 2, comprising a step of treating the field before seeding with the seed of soybean with the sulfentrazone.

### Claim 4 (depends on 2)

The method of controlling a weed according to claim 2, comprising a step of treating the field to be seeded, with the sulfentrazone simultaneously at seeding with the seed of soybean.

### Claim 5 (depends on 2)

The method of controlling a weed according to claim 2, comprising a step of treating the field after seeding with the seed of soybean, with the sulfentrazone.
