Description
Technical field
The present invention relates to a kind of herbicidal composition for Sugarbeet Fields, the composition disposably can effectively prevent and kill off Sugarbeet Fields
In annual broadleaf weed.
Background technique
Beet is a kind of height that economic value is high, and widely used crop is the main sugar source other than sugarcane, the crop
It widely cultivates, makes a variation very big.Sugar beet is most important business type, the cultivation of fodder beet and foliage heet and most of
Crop is the same.
The herbicide effects of existing Sugarbeet Fields are undesirable, need further to be improved.
Summary of the invention
The Sugarbeet Fields mixture herbicide combination containing metamitron, ethofumesate that the purpose of the present invention is to provide a kind of
Object, the herbicidal composition weeding range wide spectrum, controlling object are annual broadleaf weed, and mixture preparation uses different weedings
Mechanism has preferable preventive effect to above the average age for marriage malignant weed.
The present invention provides a kind of mixture herbicide composition for Sugarbeet Fields, the active component of the herbicidal composition by
Metamitron, ethofumesate composition.In the binary herbicidal composition, analyzed according to equivalent line principle, benzene
Metribuzin: the mass ratio of ethofumesate is (3.6562~9.8079): theoretically can reach maximum synergy to Chenopodiaceae preventive effect when 1 and makees
It is (3.7880~8.6481) with metamitron: the mass ratio of ethofumesate: theoretically reachable to pale persicaria preventive effect when 1
To maximum synergistic effect, comprehensively consider the synergy situation to two kinds of weeds, it is believed that metamitron: ethofumesate mass ratio is
(3.7880~8.6481): 1 mixture is most obvious to weeds synergistic effect, prevents and kill off the annual broad-leaved of Sugarbeet Fields for two kinds of medicament mixtures
The optimum proportioning of weeds.
The mechanism of action: ethofumesate: inhibit lipid synthesis, absorbed, then be transmitted to leaf, be not easy by after maturation by bud and root
Leaf absorb.Metamitron: for photosynthetic electron transfer inhibitor, action site is located at photosystem II, main to be absorbed by root,
It is transmitted to leaf upwards.
A kind of mixture herbicide composition for Sugarbeet Fields, it is characterized in that: the active component of the herbicidal composition
It is made of metamitron, ethofumesate: wherein metamitron: the weight percent of ethofumesate is 3.7880~

Agriculturally any dosage form of acceptable can be made in herbicidal composition of the present invention, including but not limited to:
Suspending agent, oil suspending agent, water dispersible granules, wettable powder, missible oil, aqueous emulsion etc..
The present invention is used for Sugarbeet Fields weeding, compares general single dose, and synergistic effect is obvious, can reduce spraying times, raising pair
The safety of Sugarbeet Fields reduces remaining threat, reduces the pollution to environment.The different herbicide of two kinds of mechanisms of action is mixed
Match, it is possible to reduce the generation of drug resistance.The composition is efficient, to Sugarbeet Fields safety and moderate cost.
There is addition or synergy to make Sugarbeet Fields annual broadleaf weed after metamitron and ethofumesate mixture
With no antagonism.Illustrate the two mixture for preventing and treating Sugarbeet Fields annual broadleaf weed with reasonability.
Below with reference to embodiment, the invention will be further described.
Specific embodiment
Embodiment 1:
A kind of mixture herbicide composition for Sugarbeet Fields, following weight percentage of each component are as follows:
For configuring 1000kg herbicide: weighing the metamitron 200kg that mass fraction is 100%, quality point respectively
The ethofumesate 50kg, dispersing agent 25kg, emulsifier 10kg that number is 100%, thickener 4kg, preservative 1kg, antifreezing agent
15kg, defoaming agent 1kg, water complement to 1000kg.
The preparation method of the Sugarbeet Fields mixture herbicide successively includes following steps:
Step 1: dispersing agent, emulsifier is soluble in water, it is uniformly mixed.
Step 2: metamitron is dissolved in mixed solution, and sand milling obtains aqueous solution I.
Step 3: thickener and ethofumesate are mixed, and preservative is added and is sanded, obtains solution II.
Step 4: II mixed material feeding of aqueous solution I and solution is ground repeatedly.By antifreezing agent, defoaming agent be sprayed mixer into
