Embodiment 1

[0030] One (1.0) part of imazosulfuron, 1.0 part of compound [I], 0.5 part of Neocol YSK (sodium dialkyl sulfosuccinate manufactured by Dai-ichi Kogyo Seiyaku Co. Ltd.), 2.0 parts of Toxanon GR31A (polycarboxylic acid type produced by Sanyo Chemical Industries, Ltd.), 30 parts of Kunigel V1 (bentonite produced by Kuminine Industries Co., Ltd.) and 65.5 parts of calcium carbonate were charged into a small kneader, mixed, kneaded Preparation, granulation with an extruder (RG-5M produced by Kikusui Seisakusho, Ltd.), and drying with a fluidized bed dryer (MDB-400 produced by Fuji Paudal Co., Ltd.), and then passing through a 16-48 mesh sieve Filter to obtain granules.

Embodiment 2

[0032] 1.9 parts (1.9) of imazosulfuron, 1.9 parts of compound [I], 9.0 parts of ethylene glycol, 0.3 parts of Antifoam E-20 (an antifoaming agent produced by Kao Corp.), 0.1 part of Sorbet acid, 10.0 parts of Isoelite L (cyclodextrin produced by Ensuiko Sugar Refining Co., Ltd.), 3.0 parts of New Kalgen D-1518, 2.0 parts of Agrisol FL-2017 (anionic / nonionic surface produced by Kao Corp.

Abstract

A herbicidal composition which comprises 1-(2-chloroimidazo[1,2-a] pyridin-3-ylsulfonyl)-3-(4,6-dimethoxypyrimidin-2-yl)urea (imazosulfuron) and a compound represented by the formula (I): (I) (Compound [I]) as active ingredients, wherein the weight ratio of imazosulfuron: Compound [I] is 1:0.1-1:10, has an excellent herbicidal activity for controlling weeds in crop fields or paddy fields, and causes no phytotoxicity against useful plants.

Description

technical field [0001] The present invention relates to herbicidal compositions and herbicidal methods. Background technique [0002] Currently, many herbicides are commercially available and they are widely used. However, there are many types of weeds that need to be controlled, and their growth lasts for a long time. For this reason, herbicides having higher herbicidal activity, broad weed control spectrum, long-acting and safe to crops are required. Contents of the invention [0003] The present invention provides compositions and methods for controlling various weeds, which have higher herbicidal effects and are non-phytotoxic to crops. [0004] That is, the present invention provides a herbicidal composition comprising 1-(2-chloroimidazo[1,2-a]pyridin-3-ylsulfonyl)-3-(4,6-dimethoxypyrimidine- 2-yl) urea (imazosulfuron) and a compound represented by formula (I): [0005] [0006] (Compound [I]) as an active ingredient, wherein the weight ratio of imazosulfuron-m...
