## Abstract

To provide a method which exerts excellent controlling effects on noxious organisms in a field of soybean, corn or cotton. A method for controlling noxious organisms in a field of soybean, corn or cotton, wherein at least one PPO inhibitor compound selected from the group consisting of flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen-sodium, and a compound represented by formula (I): is applied to the field before, at or after sowing a soybean, corn or cotton seed treated with ethaboxam.

## Claims

### Claim 1

A method for controlling weeds in a field of soybean, corn or cotton, wherein at least one PPO inhibitor compound selected from the group consisting of flumioxazin, sulfentrazone, and saflufenacil is applied before, at or after sowing a soybean, corn or cotton seed treated with ethaboxam.

### Claim 2 (depends on 1)

The control method according to claim 1, wherein the PPO inhibitor compound is flumioxazin.

### Claim 3 (depends on 1)

The control method according to claim 1, wherein the PPO inhibitor compound is applied to the field before sowing the soybean, corn or cotton seed.

### Claim 4 (depends on 1)

The control method according to claim 1, wherein the PPO inhibitor compound is applied to the field at sowing the soybean, corn or cotton seed.

### Claim 5 (depends on 1)

The control method according to claim 1, wherein the PPO inhibitor compound is applied to the field after sowing the soybean, corn or cotton seed.
