PURPOSE:To obtain a herbicide composition having a wide weed killing spectrum and able to exhibit sufficient weed killing effect with a small amount of dose containing a 2-nitro-5-(substituted phenoxy)benzohydroximic acid derivative and a specific benzothiadiazine derivative. CONSTITUTION:1 pts.wt. a compound expressed by formula I (R is lower alkyl) is mixed with 5-100 pts.wt. 3-isopropyl-1H-2,1,3-benzothiadiazine-4(3H)-one 2,2- dioxide expressed by formula II and further mixed with a solid or liquid carrier (e.g. kaolin clay or xylene), surfactant (e.g. alkyl sulfate) or other auxiliary (e.g. sodium alginate) for formulation, then prepared to a shape of powder, granule, emulsion, wettable power or flowable agent, etc., to afford a herbicide composition. Suitable amount for application is 0.2-1.0kg per 1ha, calculated as total amount of the active ingredients. |
