Abstract
The invention discloses a three-ingredient weeding composition and application thereof. The effective active ingredients of the three-ingredient weeding composition include a first active ingredient of fluroxypyr, a second active ingredient of cyhalofop-butyl and a third active ingredient of anilofos according to a mass ratio of (1 to 90): (1 to 90):(1 to 90). The composition can be prepared into agriculture allowed water dispersible granules, wettable powder, suspending agents, missible oil and dispersible oil suspension. The ingredients of the three-ingredient weeding composition are reasonable; the weeding effect on paddy fields is good; the activity and the weeding effect are not simple superposition of the activity and the weeding effect of all ingredients. Compared with the existing single-ingredient preparation or two-ingredient compound preparation, the three-ingredient weeding composition has the advantages that the obvious weeding effect is achieved; in addition, the obvious synergistic effect is achieved; the weed control spectrum is increased; the weed preventing and weed killing cost is reduced; the safety on crops is high.
Description
Technical field
The present invention relates to a kind of rice terrace ternary weeding composition, by active component fluroxypyr, cyhalofop-butyl and
Anilofos and auxiliary agent composition, belong to technical field of compounded pesticide.
Background technology
Fluroxypyr, English name is fluroxypyr, and chemical name is：The fluoro- pyrrole of the chloro- 6- of 4- amino -3,5- two
Pyridine -2- pyridine fluoroacetic acid 1- methyl-heptyl ester.Inner sucting conduction type herbicide after seedling.It is absorbed by plants quickly after medicine, make sensitive plant
The reaction of classical hormones class herbicide, plant deformity, distortion in thing.Temperature no affects on the final effect of its weeding, but shadow
Ring the speed that its drug effect plays.Typically when temperature is low, drug effect plays relatively slowly, stops growing after can making dunsiekte, but not immediately
Dead；After temperature raises, plant is dead quickly.In soil, leaching is not notable, and major part is distributed in 0-10 centimetre of topsoil,
Under conditions of aerobic, it is degraded into the non-poisonous materials such as 2- pyridine alcohol quickly in the effect of soil microorganism, the half-life is relatively in soil
Short, impact will not be produced on lower stubble broad leaf crop.
Cyhalofop-butyl, English name cyhalofop-butyl, chemical name is：(R) -2- [4 (4- cyano group -2- fluorobenzene oxygen
Base) phenoxy group]-butyl propionate.Cyhalofop-butyl is that uniquely have tight security to Oryza sativa L. in fragrant phenoxy phenoxy propionic acid herbicide
Kind, be Uptake and translocation herbicide.Absorbed by the blade and sheath of plant, phloem conducts, and accumulates in plant
Meristem zone, resists acetyl-CoA carboxylase, so that fatty acid is synthesized and stops, and the growth division of cell can not be normally carried out, film
The structural deteriorations containing fat such as system, finally result in Plant death.
Anilofos, English name anilofos, chemical name is：S-4 chloro- N- cumene carbamo, lmethyl O, O-
2 Methyl disulfide substituted phosphates.Absorbed by the plumelet and subterraneous stem of plant, suppression Tom Clancy Splinter Cell stretches, and makes weeds young leaves not
Easily extract out, growth stops, finally withered.The weeds effect aligning sprouting is best;Poor to the weeds effect grown up.Weeds are subject to
After medicine, growth stops, and blade is dark green, sometimes decolours, and blade shortens and thick, easily fractures, lobus cardiacus is difficult extraction, finally whole strain is withered
Extremely.The barnyard grass in 3 leaf phases and sedge weed can effectively be prevented and kill off, to rice safety.
Applicant finds still do not have the group that fluroxypyr, cyhalofop-butyl and anilofos three compound at present through retrieval
Conjugate patent.Simultaneously through long-term test it was unexpectedly observed that by fluroxypyrs different for the mechanism of action, cyhalofop-butyl and
Anilofos compound, and have obvious potentiation to rice terrace barnyard grass, Semen Euphorbiae, Herba monochoriae vaginaliss, Alternanthera philoxeroides, dried tuber, significantly
Improve the prevention effect to rice terrace grassy weed, broad leaved weed and sedge weed, expand weed control spectrum, reduce and prevent and treat into
This, improve to crop safety.
Content of the invention
It is an object of the invention to provide a kind of component is rationally, drug cost is low, and potentiation is notable, and herbicidal effect is good,
Preventing and treating spectrum is wide, the ternary weeding composition to crop safety.
Another object of the present invention is to providing above-mentioned ternary weeding composition preparation formulation.
It is still another object of the present invention to provide above-mentioned composition is in preventing and treating rice terrace grassy weed, broad leaved weed and Sha
Application on careless section weeds.
For the defect overcoming existing unitary agent or two-spot to compound, the technical scheme of Herbicidal combinations of the present invention is so
Solve：
A）First active component fluroxypyr；
B）Second active component cyhalofop-butyl；
C）3rd active component anilofos.
First active component, the second active component and the 3rd active component mass ratio are（1～90）：（1～90）：（1～

Method》With《People's Republic of China (PRC) agricultural industry criteria NY/T1155.7 2006 farm-chemical indoor determination test rule is removed
Careless agent the 7th part：The synergy of mixture measures》.
Subjects are rice direct seeding field grassy weed barnyard grass（Echinochloa crusgalli）, Semen Euphorbiae
（Leptochloachinensis）, broad leaved weed Herba monochoriae vaginaliss（Monochoria vaginalis）, Alternanthera philoxeroides
（Alternanthera Philoxeroides）, sedge weed Herba Cyperi Difformiss（Cyperus difformis）.
Active compound is configured to the test medicine needing, first single dose and each compound drug is arranged 5 variable concentrations gradients
（On the basis of pilot study result, different according to dosages distribution, Concentraton gradient setting is also different, rate of preventing and kill off 5%～
Press geometric progressions in the range of 90% to set）.If clear water compares, it is repeated 4 times.Weeds were in for 2～3 leaf phases, from low dosage to high agent
Amount carries out spraying treatment respectively.It is placed in warm indoor cultivation after process to observe, with the bottom infiltrating irrigation mode moisturizing of basin alms bowl.
Process the rear fresh weight preventive effect calculating each chemicals treatment for 21 days, by the probit value of preventive effect and the logarithm value of series concentration
Between linear regression analyses, obtain the ED of each medicament50Value, calculates the co-toxicity coefficient of mixture with the abundant method of Sun Yun（CTC）, come with this
Evaluate the activity to weeds for the reagent agent.
Co-toxicity coefficient CTC >=120 of complex preparation show as potentiation；CTC≤80 show as antagonism；80 ＜
CTC ＜ 120 shows as summation action.
