Abstract
The invention discloses a kind of containing metazachlor with the Herbicidal combinations of metribuzin, its herbicidal active component is metazachlor and metribuzin, and remaining is insecticides adjuvant；The mass fraction of metazachlor and metribuzin is 20%～80% than for 1:20～20:1, metazachlor and metribuzin quality summation mass percent in the composition；The present invention can be effectively improved actual prevention effect, reduces dosage, reduces cost, delays the drug-fast generation of disease pest and weed.
Description
Technical field
The metazachlor that the present invention relates to and metribuzin compositions, belong to pesticide herbicide, be with metazachlor,
Metribuzin is active component, is used for preventing and kill off potato fields annual grassy weeds.
Background technology
Metazachlor belongs to acetophenone amine herbicide, is mainly absorbed by weeds plumelet and immature secondary root,
Suppression vivo protein matter synthesis, makes weeds shoot enlargement, deformity, and color depth is green, ultimately results in death.Available
In anti-divided by the grassy weed of seed germination, annual dried tuber and some annual broadleaf weeds.
Metribuzin is selective herbicide, and active ingredient is conducted to top with transpiration current by weeds Root Absorption,
Also can be absorbed by blade and make limited conduction in vivo.Mainly played by the photosynthesis of suppression sensitive plant
Removing activity, after dispenser, the sprouting of each susceptible weeds is emerged unaffected, rear blade chlorisis of emerging, last nutrition
Exhausted and dead.Metribuzin can be used as sprouting front or sprouting post processing, prior to seeding or after planting Seedling previous crops soil treatment,
Soil has suitable humidity and is conducive to the absorption of root, if antecedent soil moisture should after dispenser shallow mixed soil, as Seedling
Post processing herbicidal effect is the most notable, and dosage to reduce as one sees fit, otherwise broad leaf crop can be produced poisoning.
The mixture of different pesticide species, is to improve prevention effect, expanding prevention spectrum and delay agricultural disease pest and weed
Effective ways.By pesticide 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 deeply grinding by the present inventor with the screening of metribuzin combination formula
Study carefully, find that metazachlor and metribuzin combination have potentiation to potato fields main weeds, and to Rhizoma Solani tuber osi
Safety, after further study, completes the present invention.
Summary of the invention
It is an object of the invention to solve to develop immunity to drugs farmland weed in prior art problem and actual anti-
Controlling effect poor, it is provided that one is efficiently, low toxicity, quick-acting are good and the lasting period is long, beneficially farmland weed is combined
Close the Herbicidal combinations administered.
It is a further object of the present invention to provide and be used for preventing and treating farmland weed by this Herbicidal combinations, be particularly useful for preventing
Control potato fields annual grassy weeds.
Technical scheme: a kind of containing metazachlor with the Herbicidal combinations of metribuzin, its herbicidal active component is
Metazachlor and metribuzin；The mass fraction of metazachlor and metribuzin ratio is for 1:20～20:1, pyrazoles grass
Amine and metribuzin quality summation mass percent in the composition are 20%～80%, and remaining is insecticides adjuvant.
The Herbicidal combinations of the present invention is prepared as any one agent being suitable for agriculturally using by known method
Type, reasonable dosage form has wettable powder, suspending agent, water dispersible granules.The various system of the present composition
The processing technique of agent is prior art, can be varied from according to different situations.
The auxiliary agent used in Herbicidal combinations of the present invention includes solvent, emulsifying agent, wetting agent, stabilizer, divides
Powder, thickening agent, pH adjusting agent, defoamer, antifreezing agent, packing agent etc. are of value to effective ingredient at preparation
In stable and play the known substance of drug effect, be all conventional in pesticidal preparations or allow the various compositions used,
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 compositions, each material has mixed
Closing, the composition of compositions can also the form of single dose provide, and directly mixes in tank or bucket, then before using
It is diluted to required concentration.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 Rhizoma Solani tuber osi
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 that active component resistance is produced；4. reduce Pesticide use amount, thus
Reduce cost and decrease the impact on environment.
The technology of the present invention is originated: for further appreciating that weeds are combined work by metazachlor and the grand mixture of metribuzin
With, the present inventor's mixture grand to metazachlor and metribuzin has carried out formulation screening test.
Test material:
Chenopodium glaucum linn (Chenopodium glaucum), Seed storage is collected in field.
Herba Digitariae (Digitaria sanguinalis (L.) Scop.), Seed storage is collected in field.
Test apparatus: controlled illumination box；POTTER precision laboratory spray tower；Electronic balance (sensibility reciprocal
0.1mg)；Micropipette rifle etc..
Test method: the built-in quantitative soil of porcelain alms bowl at high 6cm, diameter 9cm, by target weed seed 15
Grain sowing, in porcelain alms bowl, is placed on temperature indoor cultivation after the fine earth of lid 0.5～1cm, when target weeds dew bud
Carrying out soil spraying treatment, every porcelain alms bowl quantitatively sprays 1ml, often processes 4 times and repeats, and sets the place without medicament
Reason is comparison, tries material and be placed in temperature indoor cultivation, the growing state of routine observation target weeds, 15d after process
Rear range estimation target damage symptoms and growth inhibited situation, and claim weeds fresh weight, evaluate with target fresh weight inhibition
The medicament toxicity action to target weeds.
Test estimates target damage symptoms and growth inhibited situation after processing 15d, and claims aerial parts fresh weight,
Calculate fresh weight inhibition (%).
Evaluating herbicide associated form (NY/T1155.7-2006) according to Gowing method, its formula is as follows:
E0X Y XY/100.
In formula, X is metazachlor with certain dosage fresh weight inhibition to target weeds time alone；Y is that metribuzin is at certain
Fresh weight inhibition to target weeds when dosage is alone；E0During for metazachlor, two kinds of pharmacy mix of metribuzin
Theoretical value to target weeds fresh weight inhibition；To target when E is metazachlor, two kinds of pharmacy mix of metribuzin
The measured value of mark weeds fresh weight inhibition.
Evaluation criterion: as E E0During ＞ 10%, it is expressed as potentiation；As 10%≤E E0When≤10%,
Show as summation action；As E E0During ＜ 10%, show as antagonism.
All test datas all use DPS v14.10 statistical software to be analyzed.
Measurement result shows (see Tables 1 and 2), metazachlor and metribuzin at mixed ratio 10～20:1～
Between 20, E E0＞ 10%, is expressed as potentiation.
Table 1, different ratio metazachlor and the metribuzin synergy measurement result to chenopodium glaucum linn.
Table 2, different ratio metazachlor and the metribuzin synergy measurement result to Herba Digitariae.
