Problems solved by technology

In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance
At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all of them will show some defects and problems. limitation

Embodiment 1

[0020] Biological Assay Example 1: Screening test of oxaziclozone and bentazone formulations.

[0021] In order to further understand the combined effect of oxaziclozone and bentazone on weeds, the inventors conducted a formula screening test on the mixture of oxaziclozone and bentazone:

[0022] experiment material:

[0023] Barnyardgrass [Echinochloa crusgalli (L.) Beaw Setaria] (seeds collected in the field and preserved).

[0024] Wild Arrowhead [Sagittaria trifolia] (seeds collected and preserved in the field).

[0025] Test Instruments:

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

Abstract

The invention discloses a weeding composition containing oxaziclomefone and bentazone, which comprises effective components oxaziclomefone and bentazone and the balance of pesticide adjuvants. The mass ratio of the oxaziclomefone to the bentazone is 1:5-1:30, and the oxaziclomefone and bentazone account for 3-70 wt% of the weeding composition. The weeding composition can be prepared into dispersible oil suspending agent, suspending agent, wettable powder or water-dispersible granules according to application demands to prevent and eliminate annual weeds in rice fields. The weeding composition has better preventing and eliminating effects on rice annual weed than the single oxaziclomefone or bentazone, lowers the consumption of the pesticide, reduces the adverse effect of the pesticide on the ecological environment, and effectively solves the problem of drug resistance of weed.

Description

technical field [0001] The invention relates to a herbicidal composition containing oxaziculone and bentazone, which is used as active ingredients to prevent and control annual weeds in paddy 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, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, and saving time and labor. [0003] Oxazimidone belongs to organic heterocycles and is a systemic herbicide for paddy fields, which is mainly absorbed by the roots and bases of stems and le...
