Abstract

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

First claim

What is claimed is:

1. A method of controlling a weed in a field of soybean, corn or cotton, comprising steps of:
treating a seed of soybean, corn or cotton with one or more diamide compounds selected from the group consisting of chiorantraniliprole and a compound represented by the formula (II):

and
treating the field before, at or after seeding with the seed of soybean, corn or cotton treated with the diamide compound, with one or more PPO-inhibiting compounds selected from the group consisting of sulfentrazone, saflufenacil and fomesafen sodium; wherein
the amount of the diamide compound is 0.01 to 2 g per 1 kg of seeds, and
the amount of the PPO-inhibiting compound is 10 to 1000 g per 10000 m 2 .

2. The method of controlling a weed according to claim 1 , comprising a step of treating the field before seeding with the seed of soybean, corn or cotton, with the PPO-inhibiting compound; wherein
the amount of the diamide compound is 0.01 to 2 g, per 1 kg of seeds, and
the amount of the PPO-inhibiting compound is 10 to 1000 g per 10000 m 2 .

3. The method of controlling a weed according to claim 1 , comprising a step of treating the field to be seeded, with the PPO-inhibiting compound simultaneously at seeding with the seed of soybean, corn or cotton; wherein
the amount of the diamide compound is 0.01 to 2 g, per 1 kg of seeds, and
the amount of the PPO-inhibiting compound is 10 to 1000 g per 10000 m 2 .

4. The method of controlling a weed according to claim 1 , comprising a step of treating the field after seeding with the seed of soybean, corn or cotton, with the PPO-inhibiting compound; wherein
the amount of the diamide compound is 0.01 to 2 g per 1 kg of seeds, and
the amount of the PPO-inhibiting compound is 10 to 1000 g per 10000 m 2 .
