Problems solved by technology

However, the synergistic effect present in herbicidal mixtures of two or more herbicidally active substances is only visible in some cases
Due to differences in herbicidal performance, absorption rate, transfer, metabolism, etc., the herbicidal activity of most mixtures is lower than that of the individual components.

Embodiment 1

[0075] Embodiment 1: wettable powder

[0076] oxaflumezone

[0077] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain the wettable powder of the herbicidal composition.

Embodiment 2

[0078] Embodiment 2: suspoemulsion

[0079] oxaflumezone

[0080] Dissolve dicamba in SOLVESSO TM 200, add p-methoxy fatty acid amidobenzene sulfonate sodium to obtain the oil phase; according to the formula, fenflumezone, p-methoxy fatty acid amidobenzene sulfonate, alkylphenol polyoxyethylene ether formaldehyde condensate sulfuric acid Salt and water are ground and / or high-speed sheared to obtain a suspension of fenflumezone; the oil phase is added to the suspension phase under stirring to obtain a suspoemulsion.

Embodiment 3

[0081] Embodiment 3: water dispersible granules

[0082] oxaflumezone

[0083] Dry crushing, granulation, drying and sieving of the above formula in proportion to prepare water-dispersible granules of the herbicidal composition.

Abstract

The invention relates to a weeding composition, in particular to a weeding composition of binary formulation and applicable to corn fields. The invention provides the weeding composition, including topramezone and dicamba having a weight ratio of 2:1 to 1:50, preferably 1:10 to 1:30. The weeding composition is useful in preventing and treating field broad-leaved weeds and gramineous weeds, particularly chenopodium, Commeline communis, Echinochloa crusgalli and Eriochloa villosa.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a novel compound herbicidal composition which is binary compound and applied in corn fields. Background technique [0002] In crop farming, it is important to control weeds and protect crops that inhibit crop growth and result in lower yields. In order to reduce losses due to weeds in crop cultivation, such as poor growth or reduced crop yield, some herbicidal active ingredients that are effective in controlling the weeds and are safe to crops have been developed. To date, a large number of herbicides have been developed that have been registered and used to control weeds in certain crops. Herbicides for controlling weeds in specific crop cultivation should have sufficiently high herbicidal activity and broad herbicidal spectrum, and should be sufficiently safe for the environment and crops. However, not all herbicides can fully meet the above requirements. [0003] The most commonl...
