Embodiment 1

[0085] Example 1: 25% promasulfuron-methyl + 1% fenoxazone oil suspension concentrate

[0086] Promethazone-methyl 25%

[0087] Methazone 1%

[0088] Sodium methyl naphthalene sulfonate formaldehyde condensate 10%

[0089] Bentonite 1%

[0090] Glycerol 5%

[0091] Soybean oil supplemented to 100%

[0092] Mix the active components, dispersant, wetting agent and corn oil according to the ratio of the formula, and then grind and / or high-speed shear to obtain 25% promasulfuron-methyl + 1% oxafen oil suspension.

Embodiment 210

[0093] Example 2 10% promethazone-methyl + 2% oxafen wettable powder

[0094] Promethazone-methyl 10%

Abstract

The invention relates to a weeding composition and a method for preventing and removing weeds by using the weeding composition. The weeding composition provided by the invention comprises active components (I) and (II), wherein the active component (I) is a compound described in the formula (I) (shown in the description), the active component (II) is a compound described in the formula (II) (shown in the description), and the weight ratio of the active component (I) to the active component (II) is (100:1)-(1:100).

Description

technical field [0001] The present invention relates to a herbicidal composition and a method for controlling unwanted vegetation. Background technique [0002] When herbicides are used alone, their effect is usually only temporary, ie resistance in weeds is observed after a certain period of time. In crop protection, it is in principle desirable to increase the activity and reliability of action of active compounds. It is particularly desirable that the active compounds be effective against undesired vegetation, but at the same time be compatible with the useful vegetation concerned. It is therefore desirable that the active compounds can be used at the lowest possible application rates in order to achieve the highest possible compatibility with the useful plants. [0003] Propyrisulfuron, molecular formula C 16 h 18 o 5 N 7 SCl, its molecular structure is as follows: [0004] (Formula I) [0005] Promasulfuron-methyl is a pyrimidine-based sulfonylurea herbicide d...
