Description
Technical field
The present invention relates to agriculture field, in particular it relates to a kind of herbicidal composition, and the use of the herbicidal composition
On the way.
Background technology
Corn is one of staple food crop of China's plantation, national corn seeding area in 2015 up to 36,940,000 hectares,
Northeast and North China are mainly distributed on, its total yield is up to 2.2 hundred million tons.At present, domestic maize market demand is continuously increased, this require after
It is continuous to improve corn yield.Weeds in field strives water, strives fertilizer with corn, is one of principal element for influenceing corn yield, if not being subject to
Preventing and treating, can cause a large amount of underproduction of corn.The weeds of main harm corn field have：Lady's-grass, barnyard grass, green bristlegrass, eleusine indica, anti-branch
Amaranth, purslane, acalypha copperleaf, lamb's-quarters, Ji, field bindweed etc..And seedling stage harm is maximum, short and small, bar spire Huang of plant etc. can be caused
Have a strong impact on corn yield, can underproduction amplitude up to 35% or so.
The major herbicides kind for preventing and kill off weeds in field currently used for corn field after seedling has：Acetamide-group herbicides, such as first grass
Amine, Acetochlor etc., the drug effect of such herbicide are had a great influence by external climate condition, such as influenceed by soil moisture content, during soil moisture content difference
Herbicidal effect significantly reduces；Triazine herbicide, such as atrazine, flutter Kusatsu, simajine etc., wherein with atrazine use compared with
It is more, active highest safer to corn；Phenoxy carboxylic acid herbicides, such as the chlorine sodium salt of 2 first 4,2,4-D butyl esters etc., such weeding
Agent is generally used for cauline leaf process, prevents and kill off that corn field is annual and perennial broadleaf weed, have efficiently, quick, wide spectrum, low-residual
The features such as, but the security of crop is had a great influence by the breeding time of environmental condition (especially temperature and humidity condition), crop, using not
When being also easy to produce poisoning, meanwhile, this kind of medicament is drift strong, and poisoning is also easy to produce to crop around；Sulfonylurea herbicide, as cigarette is phonetic
Sulphur is grand, rimsulfuron etc., can effectively prevent and kill off corn field grassy weed and broad leaved weed, and its maximum feature is that high activity (uses
Dosage is generally in 5~100g/hm2), hypotoxicity and good environmental characteristics；Three ketones herbicide, such as mesotrione, it is main to use
Broad leaved weed is prevented and kill off after maize bud, especially effective to sulfonylurea resistant weed；Other class herbicides, such as paraquat and grass
The steriland herbicides such as sweet phosphine, spraying can be oriented after 40 centimetres of height of corn, effectively prevent and kill off a variety of weeds；Make it
The kinds such as grand, Dicamba, Brominal prevent corn field broad leaved weed.
With the increase of corn field herbicide service life, weeds are increasing to the resistance of existing herbicide, corn field
Between the Weed species and quality that is difficult to prevent and kill off it is increasing.Therefore, it is a kind of efficient, less toxic, low-residual new there is an urgent need to develop
Type corn field herbicide.
The content of the invention
It is an object of the invention to provide a kind of herbicidal composition and application thereof, to overcome current herbicide to be difficult to height
Effect, environmental protection, synthetically prevent and treat the defects of crops weeds in field.
To achieve these goals, first aspect present invention：A kind of herbicidal composition is provided, the composition contains first
Acid amides sulphur is grand, mesotrione and atrazine, and the weight ratio of the foramsulfuron, mesotrione and atrazine is 1：(0.01-
90)：(0.01-90).
Second aspect of the present invention, there is provided use of the herbicidal composition as described above in the weeds in field of preventing and treating crops
On the way.
Pass through above-mentioned technical proposal, foramsulfuron, mesotrione and atrazine in herbicidal composition of the invention
It is applied in combination, broad weed-killing spectrum, and a variety of weeds in field can be prevented and treated simultaneously according to special ratios, relative to oligomict first
Acid amides sulphur is grand, mesotrione or atrazine can obtain the effect of notable synergistic, and dosage is low, has both delayed herbicide resistance
Generation again it is cost-effective.The herbicidal composition of the present invention is applied to the preventing and treating of corn weeds in field, and security is good, to ecology
The protection of environment serves positive effect.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
