Problems solved by technology

[0007] According to the investigation of the previous prior art, it is found that there are no related literature reports on the combination of oxaziclozone, bensulfuron-methyl and penoxsulam in the prior art
In addition, it is known in the art that long-term single use is likely to cause weed resistance and pollute the environment. Finding a synergistic composition that can improve the weeding effect and reduce the dosage of active ingredients is the research and development focus of many domestic pesticide companies.

Embodiment 1

[0017] Example 1: Indoor determination of barnyardgrass compounded with oxazicone, bensulfuron-methyl and penoxsulam

[0018] Weeds to be tested: barnyardgrass, mature seeds were collected in the field, cultured in the laboratory, and preserved after desensitization treatment.

[0019] Drugs to be tested: oxaziclozone, bensulfuron-methyl, and penoxsulam; commercially available.

[0020] Test method: Accurately weigh the test agent, dissolve it with a small amount of acetone to make a high-concentration mother solution. When applying, it was diluted with Tween-80 aqueous solution containing 0.1% mass fraction to the dose required for the test, and 0.1% Tween-80 aqueous solution without medicament was used as blank control.

[0021] Adopt the greenhouse potting method. The soil used for the test is the special test soil collected from the untreated plot. Put the special soil for the test into the flower pot; place the flower pot in a pot filled with water, and keep the soil m...

Embodiment 2

[0026] Example 2: Indoor Determination of Combination of Oxaziclozone, Bensulfuron-methyl and Penoxsulam on Combination of Combina

[0027] Weeds to be tested: Cormina, mature seeds were collected in the field, cultivated in the laboratory, and preserved after desensitization treatment.

[0028] Test agent, test method: refer to Example 1.

[0029] Analysis of the results: the combination of oxaziclozone, bensulfuron-methyl and penoxsulam showed synergistic effects on D. chinensis.

Abstract

The invention provides a weeding composition containing oxaziclomefone, bensulfuron methyl and penoxsulam. The active ingredients of the weeding composition comprise oxaziclomefone, bensulfuron methyland penoxsulam, and the mass ratio of oxaziclomefone to bensulfuron methyl to penoxsulam is 1-20: 2-60: 1-20. The weeding composition disclosed by the invention can be used for preventing and removing annual weeds in paddy fields and has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition comprising oxaziclozone, bensulfuron-methyl and penoxsulam and an application thereof. Background technique [0002] Oxaziclodione is a systemic conduction herbicide for paddy fields. It has low usage of active ingredients, long suitable application period, good diffusivity, and long-lasting effect. It is relatively safe for rice selection. It can effectively control many kinds of annual weeds such as barnyardgrass, daughter daughter, channa sausage, moshangcai, wild sagittarius, bermudagrass, amaranthus auricularia, chickweed, and special-shaped sedges. Bensulfuron-methyl is a selective systemic herbicide. The active ingredient can diffuse rapidly in water, be absorbed by the roots and leaves of the weed and transfer to the various parts of the weed, hinder the biosynthesis of amino acids, lysine and isoleucine, and prevent the division and growth ...
