experiment example ）

[0028] The greenhouse potted method was used to determine the activity of the compound paired weeds of thiensulfuron and saflufenacil (in this experimental example, amaranthus anterior). At the same time, it was carried out with a single agent of thiensulfuron and saflufenacil. In contrast, the active component was treated with 0.1% Tween-80 aqueous solution.

[0029] A plastic nutrient bowl with a diameter of 9 cm is used to contain air-dried surface soil collected from the farmland. The soil is kept moist by water supply at the bottom, and weed seeds with full and uniform grains are sown and covered with 0.5 cm of soil. When the weeds grow to the 2-leaf stage, they are sprayed in the PWT-510 spray tower (the precise spray area is 0.2m 2 , 10mL spray solution, control spray 0.1% Tween-80 aqueous solution). 21 days after the treatment, the fresh weight of the upper part of the weeds was weighed, the fresh weight control effect was calculated, and the evaluation was performed acco...

Embodiment 1）

[0035] The dosage form of the herbicidal composition of this embodiment is a wettable powder, which is composed of the following components by weight: 18 parts by weight of thiensulfuron, 12 parts by weight of saflufenacil, and 2 parts by weight as wetting Alkyl naphthalene sulfonate as an agent, 2 parts by weight of lignosulfonate as a dispersant, and 66 parts by weight of kaolin as a solid carrier.

[0036] Among them, the above-mentioned thiensulfuron and saflufenacil come from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd.; the above-mentioned alkyl naphthalene sulfonate as a wetting agent comes from NekalBXDry of BASF; the above-mentioned as a dispersant The lignosulfonate is from TensiofixIX of OMNIChemS.A.; the kaolin used as the solid carrier is from China Kaolin Co., Ltd.

[0037] The preparation method is as follows: according to the above formula, first coarsely pulverize thiensulfuron and saflufenacil into powders with a particle size of ≤...

Embodiment 2～ Embodiment 3）

[0039] The preparation methods of Example 2 and Example 3 are the same as that of Example 1, except for the parts by weight of each component. See Table 2 for details.

Abstract

The invention discloses a weeding composition containing thiencarbazone-methyl and saflufenacil. The active component of the weeding composition is composed of the thiencarbazone-methyl and the saflufenacil with the weight ratio of 1:0.01-1:100. The weight of the active component is 1-95% of the total weight of the weeding composition. The dosage form of the weeding composition is wettable powder or water dispersible granules or an oil suspended agent or a suspending agent or dry flowable or powder or granules or missible oil or emulsion in water or microemulsion or suspension emulsion. After being compounded, the weeding composition can be used for preemergence weeding in a corn field, a sorghum field and a sugarcane field. The weeding composition can prevent and remove gramineae, cyperaceae and broad-leaved weeds at a time, and has the obvious synergistic effect.

Description

Technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing thiensulfuron and saflufenacil. Background technique [0002] The chemical name of thiensulfuron (CAS registration number 317815-83-1) is: methyl 4-[(4,5-dihydro-3-methoxy-4-methyl-5-oxo-1H -1,2,4-Triazol-1-yl)carbonylsulfonamide]-5-methylthiophene-3-carboxylic acid ethyl ester. The structural formula is as follows: [0003] . [0004] Thiosulfuron is a sulfonamidocarbonyl triazolinone herbicide and an acetolactate synthase inhibitor. It can be used in wheat, corn and other gramineous crops to effectively control broadleaf and gramineous weeds. Thiazuron-methyl has the advantages of low dosage, high activity and strong selectivity. [0005] The chemical name of saflufenacil (CAS registration number 372137-35-4) is: N'-[2-chloro-4-fluoro-5-(1,2,3,6-tetrahydro-3-methyl) Yl-2,6-dioxo-4-trifluoromethylpyrimidin-1-yl)benzoyl]-N-isopropyl-N-methylsulfonamide. ...
