Abstract
The invention relates to a weeding composition containing florasulam. The weeding composition is a mixture containing the effective components of florasulam A, fluroxypyr B and carfentrazone-ethyl C. The weeding composition can be prepared into an oil dispersion suspending agent or a suspension emulsion. According to the invention, the experiment on the weeding composition proves that the proportion is reasonable, the weeding composition can be used for preventing and removing wheat paddock broad leaves and weeds, the weeding effect is remarkable, the weeding range is wide, and the weeding composition is safe for wheat, therefore, the weeding composition is an ideal herbicide for preventing and removing weeds in a wheat paddock at present.
Description
Technical field
The present invention relates to a kind of mixed pesticide technology, specifically relate to a kind of by florasulam, fluroxypyr, composite control wheat weeds weed killer herbicide and the application thereof forming of azoles humulone.
Background technology
In the real process of agricultural production, along with scientific and technical development, using chemical agent is one of effective means of controlling weeds, but single weed killer herbicide, can only prevent and treat one or both weeds, can not eliminate all weeds, so several herbicide action mechanism differences can be arrived together by the composite of synergy, disposable weeds of preventing and kill off in wheat paddock, so not only learn from other's strong points to offset one's weaknesses, and bring into play various medicament strong points, reduce costs, saving of work and time, obviously increases economic efficiency, and is one of the effective method the most addressing the above problem.
Wheat weeds sociales mainly contain broadcasts ma wormwood artemisia, corn gromwell, Veronica, rice crock, chickweed, shepherd's purse, clearvers, field thistle, accounts for the 80%-95% of wheatland group, and is all broad leaved weed, has a strong impact on wheat yield.
Florasulam (florasulam) is the inhibitor of acetolactate synthestase (ALS).Be mainly used in winter wheat after seedling, corn field broad leaved weed as weeds such as clearvers, chickweed, Polygonums.
Fluroxypyr (fluroxypyr), is pyridine fluoroacetic acid class weed killer herbicide, has interior suction conduction, has typical hormone herbicide reaction.On cereal crop, use optimum period wider, can be used for the ground such as wheat, barley, corn, grape and orchard, pasture, forest farm and prevent and kill off broad leaved weed, as weeds such as clearvers, field bindweed, shepherd's purse, chickweed, volume stem amaranth, kitchen gardens.
Azoles humulone (carfentrazone-ethyl), is a kind of contact killing type selective herbicide, causes the accumulation of poisonous intermediate by suppressing proporphyrinogen oxidase, thereby destroys the cell membrane of weeds, makes blade withered, dead rapidly.Prevent and kill off object be mainly used in preventing and kill off broad leaved weed and nutgrass flatsedge as clearvers, white dead nettle, Veronica, piemarker, lamb's-quarters, Amaranthus retroflexus, acalypha copperleaf, precious leaf mustard, corn sow thistle (qumqi), white dead nettle, etc. weeds.The weeds such as clearvers, red heart lamb's-quarters, shepherd's purse, wartwort, corn gromwell are had to excellent imitation, and the weeds etc. that sulfonylurea herbicide produced to resistance have good activity.
The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate with other weed killer herbicide and be difficult to the weeds of eliminating.
My company is devoted to the research and development of Herbicidal compositions.At present, about florasulam, fluroxypyr composite product relevant with azoles humulone, have no report.
Summary of the invention
The object of this invention is to provide a kind of weeding compound that contains florasulam, fluroxypyr and azoles humulone for weeds of wheat control.
Technical scheme of the present invention is:
Herbicidal combinations containing florasulam, is characterized in that: the percentage by weight of florasulam is 1%～10%, fluroxypyr percentage by weight is 1%～30%, and azoles humulone percentage by weight is 1%～50%.
Described herbicidal composition, by technology known in those skilled in the art, can make any formulation allowing on agricultural chemicals, and wherein more preferably formulation has: suspension emulsion, dispersible oil-suspending agent.
Herbicidal combinations of the present invention compared with prior art, produces following beneficial effect:
By weed killer herbicide mixed, can expand herbicidal spectrum, improve herbicidal effect, extend the optimum period for applying fertilizer, reduce poisoning, reduce residual activity, delay the drug-fast generation of weed killer herbicide and development, to broad leaved weed as: broadcast ma wormwood artemisia, shepherd's purse, lamb's-quarters, clearvers, amur foxtail, Veronica, benbie texts obvious.
Below in conjunction with embodiment to further instruction of the present invention.
Implementation of an application example one:
Florasulam, fluroxypyr and azoles humulone are mixed wheat weeds active determination test are reported
1. test objective: in company's illumination box, adopt pot-culture method, the indoor biometrics that research florasulam, azoles humulone, fluroxypyr three are mixed, with the proportioning of determining that florasulam, azoles humulone, fluroxypyr are mixed, for the research and development of products of company provides foundation.
2. for examination target: broadcast ma wormwood artemisia Descurainia sophia (L.) webb.Ex Prantl
Clearvers Galium aparine var.tenerum (Gren.et Godr.) Rchb)
3. test medicine: the former medicine of 97% florasulam (The Dow Agrosciences, LLC.)
The former medicine of 90% azoles humulone (U.S. Fu Meishi company)
The former medicine of 96% fluroxypyr (Lv Ba chemical inc, Shandong)
4. the preparation of liquid:
The preparation of 4.1 single doses
According to NY/T1155.6-2006, measure, liquid adopts now with the current, and former medicine adopts after acetone solution, adds Tween 80 emulsifier, is mixed with 10% mother liquor.According to medicament characteristic, 5 dosage are from high to low set, during dispenser, with the Tween 80 water containing 0.1%, be diluted to series concentration.
4.2 florasulams: azoles humulone: the preparation that fluroxypyr is mixed
According to NY/T1155.6-2006, measure florasulam: azoles humulone: fluroxypyr is mixed by five proportionings of 1:3:10,1:3:15,1:3:20,1:3:25,1:3:30, by preparating liquid said method
5. application method: in broadcasting the ma wormwood artemisia 3-6 leaf phase, clearvers the 2nd is taken turns compound leaf phase cauline leaf even spraying and processed.By the long-pending (0.12m of the actual spray of accurate spray tower powder
2, be watered 10mL, amount to a mu water consumption 55.6Kg) accurately calculate and prepare required liquid, pending plastic basin to be gone in ring and is arranged on rotating spraying platform, even spraying is processed.Atomisation pressure 2Kg/m
2, Conic nozzle flow 100 mL/min.
6. spraying time and number of times: broadcast ma wormwood artemisia and tested on June 22nd, 2012 and carry out, clearvers is tested on June 29th, 2012 and carried out, and reagent spray is processed, and all dispenser is 1 time.
7. investigation method, time and number of times
After dispenser, record in detail the symptom of being injured (as growth inhibition, chlorosis, deformity etc.) after the emerging and emerge of weeds.30 days afterwards weighing respectively process weeds acrial part fresh weight, calculate fresh weight preventive effect.
8. synergy evaluation method
Synergy type after result of the test is used with the co-toxicity coefficient method evaluation of Sun Yunpei.
Toxicity index=(EC of standard medicament
50the EC of/tested medicament
50) * 100
The co-toxicity coefficient of mixture=(the toxicity index theoretical value of the toxicity index measured value/mixture of mixture) * 100
The ratio of toxicity index * C of the ratio+C of toxicity index * B of the ratio+B of toxicity index * A of the toxicity index theoretical value=A of mixture in mixture in mixture in mixture
Criterion: co-toxicity coefficient < 80 is antagonism; Between 80-120, being summation action, is synergistic effect during > 120
