Embodiment 1

[0022] Embodiment one: Indoor toxicity test

[0023] experiment material:

[0024] Purslane, crabgrass (seeds collected in the field and preserved)

[0025] Test Instruments:

[0026] Controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0027] experiment method:

[0028] First weigh a certain mass of 96% methazepam technical product and 95% clethodim technical product, add acetone to fully dissolve and then dilute with 0.1% Tween 80 aqueous solution to prepare single-dose mother solutions respectively, and set according to the purpose of mixing For a series of ratios, 5 to 7 concentration gradients are set 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 a light incubator and cultivated at room temperature for 10 days, and...

Embodiment 2

[0039] Example 2: 16% methazepam · clethodim suspension concentrate

[0040]

[0041] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 16% methazapyr-clethodim suspoemulsion.

[0042] This embodiment is used for preventing and controlling annual weeds in peanut fields. The dosage of 16% methazapyr clethodim suspoemulsion is 120 g.a.i. / ha for sealing treatment, and the control effect is 97.9% 10 days after the medicine; 24% methazapyr water The dosage of clethodim EC was 75g.a.i. / ha for soil treatment, and the control effect was 78.5% 10 days after application; the dosage of 15% clethodim EC was 75g.a.i. / ha for soil treatment, and the control effect was 66.1% 10 days after application. The synergistic effect of methazapyr and clethodim acid is obvious after compounding, and the efficacy of 16% methazapyr-clethodim suspoemulsion in controlling annual weeds in peanut fields i...

Embodiment 3

[0043] Example 3: 22% methazapyr-clethodim aqueous emulsion

[0044]

[0045] The above formula was mixed in proportion and sheared to prepare 22% methazapyr-clethodim aqueous emulsion.

[0046] This embodiment is used for controlling annual weeds in peanut fields, 22% methazepam · clethodim water emulsion dosage 99g.a.i. / ha soil treatment, 10 days after the drug control effect is 96.8%; 24% methazepam water emulsion The dosage of emulsion is 75g.a.i. / ha for soil treatment, and the control effect is 76.9% 10 days after application; the dosage of 15% clethodim EC is 75g.a.i. / ha for soil treatment, and the control effect is 67.6% for 10 days after application. The synergistic effect of methazapyr and clethodim is obvious after compounding, and the efficacy of 22% methazapyr-clethodim aqueous emulsion in controlling annual weeds in peanut fields is significantly better than that of 24% methazapyr aqueous emulsion and 15% methadazole Herbal Butter Cream. Due to the improvemen...

Abstract

The invention discloses a weeding composition containing imazameth and clethodim. The weeding composition comprises active components, that is, imazameth and clethodim, and the balance of pesticide additives, wherein the mass part ratio of imazameth to clethodim is (1:10) to (10:1); the mass sum of imazameth and clethodim accounts for 1-80% of the weeding composition percentage by mass. The weeding composition disclosed by the invention has a remarkable synergism function, is applicable to prevention and treatment on annual weeds in peanut fields, and is relatively applicable to a post-emergence spraying method.

Description

technical field [0001] The herbicidal composition of the present invention uses imazethapyr and clethodim as active ingredients, and is used for preventing and controlling farmland weeds, especially for controlling annual weeds in peanut fields. 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] Imazethapyr is a new type of herbicide with high efficiency and broad spectrum. It has good control effect on monocotyledonous and dicotyledonous weeds. It can not only treat soil,...
