Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and its application field, specifically Yi Zhong Yi metamifops, chlorine fluorine
Pyridine ester and the Herbicidal combinations that fluroxypyr (or its ester type compound) is effective active composition ternary built, mainly should
For preventing and kill off for paddy field weed.
Background technology
Metamifop (metamifop) is fragrant phenoxy phenoxy propionic acid inner-adsorption conduction-type herbicide, and its mechanism of action is second
Acyl coenzyme A carboxylase inhibitors, can suppress the synthesis of vegetable fatty acid, and barnyard grass, a thousand pieces of gold are prevented and kill off available for rice terrace cauline leaf process
A variety of grassy weeds such as son, rice Leersia Sw, lady's-grass, but its to broad leaved weed and sedge weed substantially without activity of weeding.
Chlorine fluorine pyridine ester (florpyrauxifen) is novel aromatic yl pyridines first acid herbicides, with wide spectrum, efficiently,
The low feature of quick-acting, consumption.Cauline leaf process after bud, grassy weed, broad leaved weed and nutgrass flatsedge are prevented and kill off available for rice terrace.
Fluroxypyr (fluroxypyr), the different monooctyl ester of fluroxypyr (fluroxypyr-meptyl) are interior
Conduction type herbicide after seedling is inhaled, the different monooctyl ester of fluroxypyr is that fluroxypyr reacts obtained esters product with alcohols.
The different monooctyl ester of fluroxypyr, fluroxypyr has good prevention effect to a variety of broad leaved weeds of rice terrace, still
It is poor to grassy weed and sedge weed prevention effect, and poisoning is also easy to produce to paddy rice.
It can be seen that when , metamifops, chlorine fluorine pyridine ester, fluroxypyr or the different monooctyl ester of fluroxypyr are used alone
There is certain defect, such as preventing and treating spectrum is narrow, poisoning is also easy to produce to paddy rice, use cost is high and weeds are also easy to produce the resistance to the action of a drug
Problems；Mutually complicated, species is various for grass when occurring due to paddy field weed, such as grassy weed, sedge weed and broad-leaved
The mixing such as weeds occurs, even if Jiang metamifop, chlorine fluorine pyridine ester, fluroxypyr or the different monooctyl ester phase of fluroxypyr
Mutual binary built is used, and there is also the defect to part Weed-control effect difference, it is impossible to is thoroughly solved paddy field weed and is caused harm.
The present inventor is Jiang metamifop, chlorine fluorine pyridine ester and fluroxypyr or three kinds of the different monooctyl ester of fluroxypyr
Effective active composition is compounded together, in the range of certain compound proportion, with significant synergistic function, to rice terrace
A variety of broad leaved weeds, grassy weed and sedge weed are respectively provided with prominent prevention effect, expand herbicidal spectrum, and reducing makes
With cost, the generation of herbicide resistance is delayed, to rice safety, has efficiently solved each single dose exclusive use or mutually binary is answered
Various problems with presence described above when using.
The content of the invention
It is an object of the invention to provide a kind of component rationally, obvious synergy, herbicidal effect is protruded, herbicidal spectrum
Extensively, the lasting period is long, and drug cost is low, weeds can be delayed to develop immunity to drugs, and to the ternary built Herbicidal combinations of rice safety.
Another object of the present invention is to provide application of the above-mentioned Herbicidal combinations in paddy field weed is prevented and kill off.
Technical scheme：To achieve the above object, the present invention provides a kind of Herbicidal combination for having and acting synergistically
Thing, active ingredient constitutes , oxazoles acyl grass You metamifop, chlorine fluorine pyridine ester, fluroxypyr (or its ester type compound)
Amine, chlorine fluorine pyridine ester, the weight ratio of fluroxypyr (or its ester type compound) three in the composition are 1~20:1:1~

(CTC) maximum is reached, is 375.81.Closed it can be seen that , metamifops, chlorine fluorine pyridine ester and fluroxypyr ternary built have
Rationality and feasibility.
The room of the metamifop of table 6, chlorine fluorine pyridine ester and the different monooctyl ester ternary built counterglow dichotomous fimbristylis herb of fluroxypyr
Interior virulence measurement result
By the visible , metamifops of table 6, chlorine fluorine pyridine ester, the mutual binary built of the different monooctyl ester of fluroxypyr, counterglow
Dichotomous fimbristylis herb is showed only as simple summation action, and counterglow dichotomous fimbristylis herb shows synergistic function after ternary built, special
Other Shi metamifops, chlorine fluorine pyridine ester and the different monooctyl ester of fluroxypyr are with 10:1:30 (by weight) compoundings, Synergistic is made
With significantly, co-toxicity coefficient (CTC) reaches maximum, is 413.77.It can be seen that , metamifops, chlorine fluorine pyridine ester and chlorine fluorine pyrrole
The different monooctyl ester ternary built of fluoroacetic acid has reasonability and feasibility.
Embodiment 8：Field control effectiveness test
Experimental field selection rice terrace is carried out, and often processing, which is set, observes each processing weeds death condition for 30 days after 3 repetitions, medicine simultaneously
Calculate preventive effect.
Each chemicals treatment of table 7 prevents and kill off the field control effectiveness test result of paddy field weed
30 Tian metamifops, chlorine fluorine pyridine ester and chlorine fluorine pyrrole oxygen second after medicine it can be seen from the field test results of table 7
Rice Leersia Sw, shaven head of each example composition preparation of acid or the different monooctyl ester ternary built of fluroxypyr to rice terrace
The weeds such as barnyard grass, Eclipta prostrata, bog pondweed, wild water chestnut, miliary fimbristylis herb have excellent prevention effect, and preventive effect is bright up to more than 80%
It is powerful and influential to be better than that each single dose is used alone or mutually binary built is used, wherein (the 26% metamifop chlorine fluorine pyridine of embodiment 2
The dispersible oil-suspending agent of ester fluroxypyr) and (the 41% metamifop chlorine fluorine pyridine ester chlorine fluorine pyrrole oxygen of embodiment 5
2-ethyl hexyl ethanoate missible oil) preventive effect more protrude, preventive effect is up to more than 90%.Simultaneously during pilot survey non-Fa Xian oxazoles
Each example composition system of acyl grass amine, chlorine fluorine pyridine ester and fluroxypyr or the different monooctyl ester ternary built of fluroxypyr
Agent produces poisoning to paddy rice.
In summary, a kind of Herbicidal combinations with synergy of the present invention, obvious synergy, phase
It is used alone than each single dose or mutually binary built is using herbicidal spectrum is expanded, is improved preventive effect, can effectively prevent and kill off rice terrace wealthy
A variety of weeds such as leaf weeds, grassy weed and sedge weed, the lasting period is long, and use cost is low, to rice safety, is worth
Popularization and application in agricultural production.
