Abstract
The invention discloses a kind of Herbicidal combinations containing metazachlor and Oxadiargyl, its herbicidal active component is metazachlor and Oxadiargyl, and remaining is insecticides adjuvant；The mass fraction of metazachlor and Oxadiargyl is than for 1:30～20:1, and metazachlor and Oxadiargyl quality summation mass percent in the composition are 20%～80%；According to existing pesticide processing technology, the present invention can be prepared as wettable powder, suspending agent, water dispersible granules, is used for preventing and kill off potato fields annual grassy weeds.Effect of the present invention is substantially better than metazachlor or Oxadiargyl, expands herbicidal spectrum, time and labour saving, reduces dosage.
Description
Technical field
A kind of preventing and treating potato fields weeds composition that the present invention relates to, is with metazachlor and Oxadiargyl
For herbicidal active component.
Background technology
Metazachlor belongs to acetophenone amine herbicide, mainly passes through weeds young shoot and immature secondary root absorbs,
Suppression vivo protein matter synthesis, makes weeds shoot enlargement, deformity, and color depth is green, ultimately results in death.Available
In the anti-grassy weed divided by seed germination, annual nutgrass flatsedge and some annual broadleaf weeds.
Before the selective bud of Oxadiargyl heterocyclic, post-emergence herbicide herbicide, by weeds young shoot or seedling
Contacting with medicament, absorbing and cause effect, dispenser after seedling, weeds are absorbed by aerial part, and medicament enters
It is accumulated in the vigorous position of growth, Developing restraint after plant, cause weeds tissue to rot dead.At illumination bar
Competence exertion herbicide effect under part, but have no effect on photosynthetic Hill reaction.Weeds are from rudiment to 2-
3 leaf phases are all to this susceptibility sense, best with weeds budding period pesticide supplying effect, decline with weeds effect of growing up.Right
Annual gramineae, Cyperaceae, broad leaved weed and some perennial weeds effects are notable.
The mixture of different pesticide species, is to improve prevention effect, expanding prevention spectrum and delay agricultural disease pest and weed
Effective ways.By agricultural chemicals toxicity test, filter out rational proportioning, actual preventing and treating effect can be effectively improved
Really, reduce dosage, reduce cost, delay the drug-fast generation of disease pest and weed, be that agricultural pest is combined
Close the important means administered.Metazachlor has been carried out deep with the screening of Oxadiargyl combination formula by the present inventor
Entering research, discovery metazachlor and Oxadiargyl combination have synergy or are added work to potato fields main weeds
With after further study, completing the present invention.
Content of the invention
It is an object of the invention to solve that herbicidal spectrum in prior art is single and effect poor, one is provided
Efficiently, herbicidal spectrum is wide, delay the resistance to the action of a drug to produce, the beneficially Herbicidal combinations of the farmland weed comprehensive regulation.
It is another object of the present invention to this Herbicidal combinations is applied to prevent and kill off potato fields annual grassy weeds.
Technical solution of the present invention: a kind of its weeding of the Herbicidal combinations containing metazachlor and Oxadiargyl is lived
Property composition is metazachlor and Oxadiargyl；Metazachlor is 1 with the mass fraction ratio of Oxadiargyl:
30～20:1, metazachlor and Oxadiargyl quality summation mass percent in the composition be 20%～
80%, remaining is insecticides adjuvant.
The known method of the Herbicidal combinations of the present invention is prepared as any one agent being suitable for agriculturally using
Type, reasonable formulation has wettable powder, suspending agent, water dispersible granules.The various system of the present composition
The processing technology of agent is prior art, can be varied from according to different situations.
The auxiliary agent using in Herbicidal combinations of the present invention includes solvent, emulsifying agent, wetting agent, stabilizer, divides
Powder, thickener, pH adjusting agent, defoamer, antifreezing agent, packing agent etc. are of value to active ingredient at preparation
In the stable and known substance that plays drug effect, be all conventional in pesticidal preparations or allow the various compositions using,
Concrete composition and consumption are determined by test according to recipe requirements.
Product described in the invention can provide with the form of finished product preparation, and i.e. in composition, each material has mixed
Closing, the composition of composition also can provide with the form of single dose, directly mixes in tank or bucket, then before using
Concentration required for being diluted to.The frequency of administration of the present composition and amount of application are with weather conditions and weeds feelings
Condition changes and changes, and can reach, by using suitable dosage, the purpose prevented and kill off.
Herbicidal combinations of the present invention is applicable to prevent and kill off potato fields annual grassy weeds, in use should be potato
Use before broadcasting rear seedling.
The Herbicidal combinations that the present invention provides, generally uses and is watered spray method use, it is also possible to as required
Use other use technology agriculturally applied.
Compared with prior art, the beneficial effects of the present invention is: be 1. significantly improved preventive effect；2.
Expand and prevent and kill off spectrum；3. delay weeds to produce active component resistance；4. reduce Pesticide use amount, thus
Reduce cost and decrease the impact on environment.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage more short and sweet, the present invention is with in detail below
Embodiment illustrates, but the present invention is only limitted to absolutely not these examples.It is preferable that the following stated is only the present invention
