Problems solved by technology

However, due to the limitation of its mechanism of action (no systemic activity), all weeds are fully covered when used, and it is ineffective for weeds that grow after application.
There are also the shortcomings of narrow application period, long residual effect period and poor safety.

Embodiment 1）

[0025] The dosage form of the high-efficiency wheat field herbicide composition of the present embodiment is a wettable powder, which consists of the following components by weight: 20 parts by weight of ximazone, 20 parts by weight of pyrentrazone-ethyl, 4 parts by weight of Fatty amide N-methyl taurate of wet agent, 6 parts by weight of calcium dodecylbenzenesulfonate as a dispersant, 40 parts by weight of kaolin as a carrier and 10 parts by weight of white carbon black as a carrier . The parts by weight of each component listed above are also called formulas. In the above components, both carfentrazone-ethyl and sammazone are active components, and the wetting agent and the dispersing agent are both auxiliary agents.

[0026] The above-mentioned mefentrazone-ethyl and salmazone as the active components all come from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd., and the purity meets the relevant quality requirements. The above fatty amide N...

Embodiment 2）

[0029] The dosage form of the herbicide composition of the present embodiment is a water-dispersible granule, which is composed of the following components by weight: 10 parts by weight of ximazone, 15 parts by weight of pyrentrazone-ethyl, 3 parts by weight of Diisooctyl sulfonate sodium succinate, 5 parts by weight of calcium lignosulfonate as a dispersant, 2 parts by weight of urea as a disintegrant, 57 parts by weight of kaolin as a carrier and 8 parts by weight of silica as a carrier. The parts by weight of each component listed above are also called formulas. The carfentrazone-ethyl and sammazone in the above components are all active components, and the wetting agent, dispersant and disintegrating agent are all auxiliary agents.

[0030] The sources of the above-mentioned carfentrazone-ethyl, salmazone, kaolin and white carbon black are the same as those in Example 1. The above-mentioned sodium diisooctyl sulfonate used as a wetting agent comes from AKZO Nobel Company...

Embodiment 3）

[0033] The dosage form of the herbicide composition of the present embodiment is still water-dispersible granules, and the rest of the water-dispersible granules are the same as in Example 2, except that the proportioning of each component described is: 30 parts by weight The salmazone, 20 parts by weight of carfentrazone-ethyl, 4 parts by weight of sodium dioctyl succinate sulfonate as a wetting agent, 6 parts by weight of calcium lignosulfonate as a dispersant, 3 parts by weight 20 parts by weight of urea as a disintegrant, 20 parts by weight of kaolin as a carrier, and 17 parts by weight of white carbon black as a carrier.

[0034] The preparation method is the same as in Example 2.

Abstract

The invention discloses a high-efficiency wheat field herbicide composition which is prepared from an active component, an assistant and a carrier, wherein the active component is composed of tralkoxydim and carfentrazone-ethyl; the weight ratio of the tralkoxydim to the carfentrazone-ethyl is 1:40-40:1; and the active component accounts for 5-90% of the composition by weight. The preparation formulation of the composition can be wettable powder, moisture granules, dry suspending agent or suspending agent. The high-efficiency wheat field herbicide composition has the advantages of wide weed control spectrum, high activity, long application optimum period, high safety for current crops and succession crops, small influence on environment and ecology, and the like.

Description

technical field [0001] The invention relates to a herbicide, in particular to a high-efficiency wheat field herbicide composition. Background technique [0002] The chemical name of salmazone (also known as benzotrione, CAS No. 87820-88-0) is: 2-[1-(ethoxyimino)propyl]-3-hydroxy-5-(2,4 ,6-trimethylphenyl)cyclohexen-2-one. The structural formula is as follows: [0003] [0004] It is a cyclohexanedione oxime ether herbicide, which is mainly applied to wheat and barley fields to control gramineous weeds such as sagegrass, windweed, oats, Swiss ryegrass, foxtail, etc. After being absorbed by leaves , in the phloem is transferred to the growth point, where new growth is inhibited. The effect of controlling wild oats at 200-350g / ha is better than that of diclofop at the recommended dose, and the application period is wide, which can almost completely control wild oats before the end of tillering stage, and the inhibition period can be extended to the jointing stage. Safe f...
