Embodiment 1

[0019] Biological Assay Example 1: Indoor Toxicity Assay Test

[0020] experiment material:

[0021] Commelina (seeds collected and preserved in the field).

[0022] Barnyardgrass (seeds collected in the field and preserved).

[0023] Test Instruments:

[0024] Controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0025] experiment method:

[0026] Firstly weigh a certain quality of 96% bispyribac technical and 95% flunmezone sulfentrame technical, add acetone to fully dissolve, then dilute with 0.1% Tween 80 aqueous solution, and prepare single-dose mother liquor respectively, according to the purpose of mixing Set a series of ratios, and set 5 to 7 concentration gradients for each ratio. Select representative sensitive weed seeds according to the single-dose herbicidal spectrum for future use. After the treatment of the selection number is carried out with soil treatment, it is placed in ...

Embodiment 1

[0036] Preparation Example 1: 12% bispyribac and 4% flunmezone sulfentrame wettable powder

[0037]

[0038] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 12% bisclobacin · flunzone-sulam wettable powder.

[0039] This embodiment is used to prevent and eliminate annual weeds in rice seedling throwing and transplanting fields, and the amount of 12% bispyribac-sulfazone wettable powder is 45g.a.i. / ha soil treatment, and the control effect is 93.2% 10 days after the drug; 20% bispyribac wettable powder dosage 45g.a.i. / ha soil treatment, the control effect is 76.1% 10 days after the application; 15% fluketone sultamein EC dosage 15g.a.i. / ha soil treatment, 10 days after the application 75.2% ; The synergistic effect is obvious after compounding bispyribac-ether and tricarbazone-sulamme, and the control effect of 12% bispyribac-sulfamet-flumezone-sulam wettable powder is obviously better than that of ...

Embodiment 2

[0040] Formulation Example 2: 18% Bisbiben-Sulfonacil Suspending Concentrate

[0041]

[0042] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare 18% biscibclofen·sulcapone suspending agent.

[0043] This embodiment is used for the prevention and control of annual weeds in rice seedling throwing and transplanting field, 18% Bispyribac-Sulfonazone suspending agent dosage 45g.a.i. / ha soil treatment, the control effect is 92.9% after 10 days of medicine; 10 The dosage of % bispyribacin suspending agent was 45g.a.i. / ha for soil treatment, and the control effect was 71.9% 10 days after application; The synergism is obvious after the combination of fenpyrafen and flunone sulfentrame, and the efficacy of 18% bispyribacin · flunmetribyl sulfentrame suspending agent in controlling annual weeds in rice seedlings and transplanting fields is significantly better than that of 10% bisp...

Abstract

The invention discloses a farm chemical composition containing bispyribac-sodium and triafamone. The farm chemical composition comprises common assistants, bispyribac-sodium and triafamone. A mass part ratio of bispyribac-sodium to triafamone is 10: 1 to 1: 10. The total mass of bispyribac-sodium and triafamone is 1-80% that of the farm chemical composition. The farm chemical composition is suitable for preventing and removing annual weed in the paddy field. The bispyribac-sodium and triafamone compound produces obvious synergism. A use amount of active ingredients in the bispyribac-sodium and triafamone compound is obviously less than that of a single-ingredient agent.

Description

technical field [0001] The pesticide composition involved in the present invention uses bispyribac and tricarbazone as active ingredients and is used for preventing and controlling farmland weeds, especially for controlling annual weeds in paddy fields and the like. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Flucarbazone is a benzoic acid herbicide and is a highly active acetolactate synthase (ALS) inhibitor. After application, this product can be quickly absorbed ...
