Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, and in particular to one kind is with chlorine fluorine pyridine ester and third
Careless amine/butachlor/mefenacet is the Herbicidal combinations of the Synergistic of active ingredient, it is adaptable to prevent and kill off rice terrace annual
Weeds.
Background technology
Paddy rice is one of main cereal crops of China, and herbicides for use in paddy is a great problem in production.With weeding skill
Many weeds in the development of art and the emergence of herbicide, farmland are increasingly difficult to kill.Different herbicides are compounded into
To solve a kind of trend of weed problem at present.
Chlorine fluorine pyridine ester is the 2nd arylpicolinic acids esters weeding that Tao benefit agriculture is developed after fluorine chloropyridine ester
Agent.Chlorine fluorine pyridine ester, with absorbability, can be conducted and accumulated through xylem and bast by the blade and root absorption of plant
The separate living tissue in weeds is tired out, so as to play activity of weeding.Chlorine fluorine pyridine ester is cauline leaf process after bud, for including paddy rice
Many crops, many areas prevent and kill off grassy weed, broad leaved weed and nutgrass flatsedge.Such as barnyard grass, bald barnyard, rice barnyard grass, moleplant seed grass
Section weeds, piemarker, rhizoma alismatis, water amaranth, three-coloured amaranth, artemisiifolia, lamb's-quarters, Horseweed Herb, Brittle Falsepimpernel Herb, climbing seedbox herb, Monochoria korsakowii, arrowhead, Siberian cocklebur etc. are wealthy
Leaf weeds, the sedge weed such as difformed galingale herb, chufa, cyperus iria, the rhizome of nutgrass flatsedge, miliary fimbristylis herb.Due to chlorine fluorine pyridine ester
The mechanism of action is novel, so as to solve known resistance problem, including to acetolactate synthestase（ALS）Inhibitor, acetyl
CoA carboxylase enzyme（ACCase）Inhibitor, p-hydroxyphenypyruvate dioxydenase（HPPD）Inhibitor, propanil, dichloroquinoline
Acid, glyphosate, triazine herbicide etc. produce the weeds of resistance.There is extraordinary activity to rice terrace resistance barnyard grass.
Pretilachlor and butachlor belong to acetamide-group herbicides, and the mechanism of action of pretilachlor is cell division inhibitor, are applicable
Barnyard grass, bald barnyard, moleplant seed, eleusine indica, needle spikesedge herb, water amaranth, difformed galingale herb, false loosestrife, Monochoria vaginalis etc. are prevented and kill off in rice terrace
Annual gramineae and broad-leaved section weeds.Butachlor is mainly absorbed by weed bud and immature secondary root, suppresses internal egg
White matter is generated, and is made the enlargement of weeds shoot, deformity, is ultimately resulted in death.Only a small amount of butachlor can be absorbed by rice seedling, Er Qie
Internal rapid safe catabolism, thus rice seedling has larger drug-resistant capability to it.Butachlor stability in soil is small, steady to light
It is fixed, it can be decomposed by edaphon, to second stubble crop safety.It is mainly used in transplanting, dry rice seedling rice field, effective anti-divided by kind
The grassy weed of sub- rudiment, annual nutgrass flatsedge and annual broadleaf weed, such as barnyard grass, moleplant seed, difformed galingale herb, crack rice Sha
Grass, needle spikesedge herb etc..There is favorable effect to Monochoria vaginalis, Drilgrass, cusp flower and firefly Lin etc., but it is a variety of to water Rhizoma Sparganii, angustifolia arrowhead herb etc.
Year, raw weeds were nearly unavailable.
Mefenacet is selective inner sucting conduction type acyl aniline herbicide, is cell division inhibitor, to young former female
The division of cell has especially strong inhibitory action.It is main to be absorbed by bud scale and root, conducted through xylem and bast to weeds
Young shoot and tender leaf, prevent weed growth point cell division elongation, growth be gathered in quickly after grassy weed contacts this medicine
At point.Suppression cell division, increase are played to cell particularly mother cell, so as to hinder the growth of barnyard grass until dead.Can have
Effect prevents and kill off grassy weed, has special efficacy in rudiment to 2 leaf phases to barnyard grass, to moleplant seed, needle spikesedge herb, wartwort, Monochoria vaginalis, successively
Dish, difformed galingale herb, flat nutgrass flatsedge, cyperus iria and aquatic nutgrass flatsedge also has certain preventive effect for many years.
The content of the invention
In consideration of it, it is an object of the invention to provide a kind of Herbicidal combinations and its preparation.The Herbicidal composition for rice field
With significant synergistic function, expansion herbicide controlling spectrum, prevention effect are good, safety and environmental protection, and the Herbicidal combinations can be prepared into
Wettable powder, water dispersible granules, aqueous suspension agent, suspension emulsion, microemulsion, aqueous emulsion, missible oil, can make as agent for removing grass in paddy field
With.
To realize the goal of the invention of the present invention, the present invention provides following technical scheme：

2）Field control effectiveness test
Reagent agent：The embodiment S1-15 of chlorine fluorine pyridine ester and pretilachlor；The embodiment S1-15 of chlorine fluorine pyridine ester and butachlor；
The embodiment S1-15 of chlorine fluorine pyridine ester and mefenacet.
Comparison medicament：Comparative example D1-4.
Subjects：Grass family：Barnyard grass；Broad-leaved section：Monochoria vaginalis；Cyperaceae：Difformed galingale herb.
Test method：
According to the area of experimental plot, the good various medicaments of precise, and be watered after dilution, using knapsack sprayer, carry out
Even spraying, the special Fan spray head of sprinkler selection herbicide.During spraying, it should be noted that decoction is uniformly sprayed application into experimental plot
In, accomplish the phenomenon sprayed without drain spray, more.20d, 40d observe weeds death condition after medicine respectively after experiment, and relatively more various
The activity of weeding of medicament, is specifically shown in Table 4-1,4-2,4-3,5-1,5-2,5-3.In addition, crop is also observed in 1-15d after medicine
The condition of production, to investigate whether medicament has poisoning to crop, be specifically shown in Table 6-1,6-2,6-3.
Table 4-1 uses chlorine fluorine pyridine ester and effect of the pretilachlor after 20 days
Table 4-2 uses chlorine fluorine pyridine ester and effect of the butachlor after 20 days
Table 4-3 uses chlorine fluorine pyridine ester and effect of the mefenacet after 20 days
Table 5-1 uses chlorine fluorine pyridine ester and effect of the pretilachlor after 40 days
