Problems solved by technology

[0008] According to the investigation of the previous prior art, it is found that there are no relevant literature reports on the compounding of oxaziclozone, pretilachlor and pyrizachlor 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 Barnyard Grass Compounded with Oxazimidone, Pretilachlor and Pyriflufen

[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, pretilachlor, and pyrizachlor; purchased from the market.

[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 moist ...

Embodiment 2

[0026] Example 2: Indoor Determination of Oxaziculone, Pretilachlor and Pyrizachlor Compound Pair of Cyperus

[0027] Weeds to be tested: Heterogeneous sedge, 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 compound composition of oxaziculone, pretilachlor and pyrizachlor showed different joint effects on heterocystic sedges. When the mass ratios of oxaziclozone, pretilachlor and pyrizachlor were 0.8:6:1.2 and 0.8:14:1.2, it showed synergistic effect; other ratios showed additive effect.

Abstract

The invention provides a weeding composition containing oxaziclomefone, pretilachlor and pyriminobac-methyl. The active ingredients of the weeding composition comprise oxaziclomefone, pretilachlor andpyriminobac-methyl, and the mass ratio of oxaziclomefone to pretilachlor to pyriminobac-methyl is 1-15: 1-50: 1-15. 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, pretilachlor and pyrizachlor 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. Pretilachlor is a herbicide in paddy fields, which can be absorbed through plant hypocotyls, mesocotyls and coleoptiles, and slightly absorbed by roots, directly interfering with protein synthesis in weeds. And have indirect effects on photosynthesis and respiration. The injured weed seedlings are disto...
