Description
Technical Field
The invention relates to the field of herbicides, in particular to a weeding composition containing flupyrsulfuron, oxaziclomefone and clomazone.
Background
The flusulfuron-methyl belongs to sulfonylurea herbicides, is an acetolactate synthase (ALS) inhibitor, can be used for treating soil or stems and leaves of paddy fields, and can inhibit biosynthesis of branched-chain amino acids such as valine, leucine and isoleucine by inhibiting acetolactate synthase of plants after being absorbed by roots, stems and leaves of the plants, so that synthesis of proteins is destroyed, synthesis of DNA and cell division and growth are interfered, and finally plant death is caused.
Oxazinone belongs to organic heterocyclic ring, is a systemic conduction type paddy field herbicide, is absorbed by roots of weeds to stop growth of new roots and new leaves, and is yellow in stem and leaf parts and dead of weeds, and is mainly used for preventing and killing important broadleaf weeds, sedge weeds, barnyard weeds and the like, and barnyard grass removing has special effects and can also be used for lawn weeding. Is safe to rice, and has no adverse effect on wheat, barley, carrot, cabbage, onion and the like of aftercrop crops.
Clomazone is a selective pre-emergence herbicide, can be upwards transmitted to each part of plants through root and bud absorption, so that synthesis of isoprene compounds is inhibited, biosynthesis of carotene and chlorophyll of sensitive plants is hindered, the plants can sprout out of soil, but have no pigment and die in a short period, and the clomazone is mainly used for preventing and killing broadleaf weeds and gramineous weeds in soybean fields, and can also be used for cassava, corn, rape, sugarcane and tobacco fields.
Although the flupyrsulfuron, oxazin and clomazone can effectively remove weeds, the weeding composition is limited by crop safety, the weeding spectrum is limited, the generation of weed resistance is easy to occur after long-term single use, and the environment is polluted.
How to verify the combined action effect of the weeding composition formed by compounding flupyrsulfuron, oxaziclomefone and clomazone is the key of the invention, so that a weeding composition containing flupyrsulfuron, oxaziclomefone and clomazone is needed to solve the problems.
Disclosure of Invention
In order to overcome the technical problems, the invention aims to provide a weeding composition containing flupyrsulfuron, oxaziclomefone and clomazone, which comprises the following components: by reasonably compounding flupyrsulfuron, oxazin and clomazone, as the action mechanisms of flupyrsulfuron, oxazin and clomazone are different, the flupyrsulfuron, oxazin and clomazone can be absorbed by weeds in a plurality of modes at the same time after being compounded, and the problem that the combined action effect of the existing weeding composition formed by compounding the flupyrsulfuron, oxazin and clomazone is not verified yet is solved.
The aim of the invention can be achieved by the following technical scheme:
the weeding composition containing flupyrsulfuron, oxaziclomefone and clomazone comprises active ingredients and auxiliary materials;
the mass ratio of the active ingredients to the auxiliary materials is 1:0.5-4;
the active ingredients comprise flupyrsulfuron, oxazin and clomazone.
As a further scheme of the invention: the mass ratio of the flupyrsulfuron to the oxaziclomefone to the clomazone is 1-10:1-10:1-50.
As a further scheme of the invention: the mass ratio of the flupyrsulfuron to the oxaziclomefone to the clomazone is 1:1:50.
as a further scheme of the invention: the auxiliary materials are all raw materials except the effective components in the pesticide formulation of the weeding composition.
As a further scheme of the invention: the pesticide formulation is water aqua, soluble granule, wettable powder, oil suspending agent, aqueous emulsion and microemulsion.
As a further scheme of the invention: the use of the herbicidal composition for controlling weeds in crop fields.
As a further scheme of the invention: the weeds are annual and perennial grassy weeds, broadleaf weeds and sedge weeds.
The invention has the beneficial effects that:
the weeding composition containing flusulfuron, oxazinone and clomazone is prepared by reasonably compounding flusulfuron, oxazinone and clomazone, and has good control effects on annual and perennial grassy weeds, broadleaf weeds and sedge weeds as the action mechanisms of flusulfuron, oxazinone and clomazone are different and can be absorbed and acted by weeds in various modes at the same time after compounding, so that the weeding spectrum can be enlarged, obvious synergistic effect is shown, the influence of different herbicides on metabolic pathways is difficult to eliminate by the weeds, the generation of weed resistance is further delayed, the dosage of single herbicide can be reduced, and the environmental pollution is also reduced.

Test examples
Test object: rice weeds: annual and perennial grassy weeds, broadleaf weeds and sedge weeds;
test agent: the agents of examples 1-8 and comparative examples 1-3;
the test method comprises the following steps: the weeds are in the 2-3 leaf stage, the medicament is diluted by 800 times by adding water, and the stem and leaf are sprayed for 1 time by adopting a knapsack sprayer, wherein the dosage of the medicament is 80g a.i/hm 2 Fresh weight control effect after 30 days of investigation.
The test results are shown in the following table:
| medicament | Gramineous weeds preventing effect, percent | Broad leaf weed control effect, percent | Weeds of the family Cyperaceae% |
| Example 1 | 94.9 | 94.0 | 92.8 |
| Example 2 | 92.4 | 92.5 | 91.9 |
| Example 3 | 96.1 | 94.8 | 95.3 |
| Example 4 | 94.1 | 93.8 | 93.4 |
| Example 5 | 91.8 | 91.7 | 91.3 |
| Example 6 | 92.2 | 92.7 | 93.0 |
| Example 7 | 93.6 | 93.9 | 93.2 |
| Example 8 | 95.4 | 93.9 | 94.7 |
| Comparative example 1 | 62.3 | 62.9 | 61.0 |
| Comparative example 2 | 70.2 | 73.5 | 72.1 |
| Comparative example 3 | 73.1 | 72.4 | 72.8 |
Referring to the data in the table, it can be known that the flucarbazone, oxazin and clomazone can be used independently to prevent and treat weeds, but the effect is not obvious enough, and the flucarbazone, oxazin and clomazone are reasonably compounded to play an optimal prevention effect, wherein when the mass ratio of the flucarbazone to the oxazin to the clomazone is 1:1: the prevention effect on weeds at 50 can reach 94.8% or more.
