To provide a technology for controlling weeds and the like. A herbicidal composition comprising at least one compound selected from Group A, and dicamba N,N-bis-(3-aminopropyl)methylamine salt has a weed control effect: Group A: a group consisting of flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen and a compound represented by the formula (I):

Herbicidal composition

The present invention relates to a composition comprising crystal of flumioxazin which shows a powder X-Ray diffraction pattern having diffraction peaks with 2&#x3b8; values (&#xb0;) shown in Table 1 of the specification, the pattern being obtained by CuK&#x3b1; rays diffraction analysis, and one or more herbicidal compounds selected from the group B-1, B-2, B-3, B-4, B-5, B-6, B-7, B-8, B-9, B-10, B-11 and B-12 described in the specification. According to the present invention, a wide range of weeds can be controlled in a crop field, land under perennial crops, or non-crop land.

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 is applied to the field before, at or after sowing a soybean, corn or cotton seed treated with fludioxonil.

Method for controlling noxious organisms

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): 

A method of controlling weeds in a soybean or cotton field, which comprises the step of applying one or more 4-hydroxyphenylpyruvate dioxygenase inhibitory active compounds and flumioxazin in an effective amount to weeds in a soybean or cotton field, or a place where weeds would grow, said 4-hydroxyphenylpyruvate dioxygenase inhibitory active compounds being selected from the group consisting of isoxaflutole, mesotrione, sulcotrione, topramezone, pyrasulfotole, tembotrione and bicyclopyrone.
