Abstract
The present invention relates to the Herbicidal combinations containing foramsulfuron and halosulfuronmethyl and atrazine, it is made up of effective constituents A, B, C and suitable insecticides adjuvant, wherein effective constituents A is foramsulfuron Tianjin, B is halosulfuronmethyl, C is atrazine, the percentage by weight of effective constituents A, B, C in the composition is respectively 1%~20%, 1%~20%, 1%~50%, and remaining is insecticides adjuvant.Instant component is reasonable, has synergistic effect, makes up the defects of incompleteness of herbicide controlling spectrum or activity for some weed caused by herbicide single use are relatively low, the defects of quick-acting is poor, reduces resistance risk caused by single compound or dual use.The prevention effect of the present invention is significantly improved than single dose, reduces the dosage of agricultural chemicals, reduces adverse effect of the agricultural chemicals to ecological environment；Comprehensive regulation important in inhibiting to Weed Resistance, there is huge economic benefit and social benefit.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and its application field, and specifically one kind is with foramsulfuron, chlorine pyrrole
Sulfometuron Methyl and the Herbicidal combinations that atrazine is active ingredient, suitable for preventing and kill off corn field annual grassy weeds.
Background technology
Foramsulfuron (foramsulfuron), sulfonylurea systemic herbicide, can be that weeds cauline leaf and root are inhaled
Receive, then conducted in plant, cause sensitive plant growth retardation, cauline leaf chlorisis, gradually withered, generally 20-25
It is dead, but needs longer time to some perennial weeds in the case where temperature is relatively low.The dispenser medicine before 4 leaf phases after bud
Imitate, dispenser drug effect declines when seedling is big.The medical instrument has an activity of weeding before bud, but activity is low compared with after bud, can prevent and kill off it is annual and
Perennial grassy weed, part broad leaved weed.Experiment shows that the weeds strong to Drug Sensitivity have And-gather grass, green bristlegrass, wild swallow
Wheat, Amaranthus retroflexus；The medium weeds of sensitiveness have Ben's knotweed, rule grass, purslane, Monochoria vaginalis, Siberian cocklebur and piemarker, nutgrass flatsedge；Sensitiveness
Poor weeds mainly have lamb's-quarters, black nightshade, Commelina communis, summer cypress and weasel hemp nettle.
Halosulfuronmethyl (halosulfuron-methrl), it is sulfonylurea wide spectrum selective inner-adsorption conduction-type herbicide,
Mainly absorbed by root system, can also be absorbed by cauline leaf, shifted rapidly in weeds plant body, suppress growth, weeds are gradual
Death, annual broadleaf weed and sedge weed can be prevented and kill off, suitable for crops such as corn, rice.
Atrazine (atrazine), it is sym-trinitrobenzene corn herbicide, is mainly absorbed by plant root
And conduct upwards, suppress the photosynthesis of weeds, make its withered.Its herbicide controlling spectrum is wider, can prevent and kill off a variety of annual gramineaes
And broad leaved weed, suitable for the dry crops such as corn, sorghum, sugarcane, fruit tree, nursery, forest land prevent and kill off lady's-grass, barnyard grass, green bristlegrass,
Nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, especially there is preferably selectivity to corn (because having removing toxic substances in Corn
Mechanism), also there is certain inhibitory action to some perennial weeds.
Foramsulfuron, halosulfuronmethyl, the compounding of atrazine are without relevant report.
The present invention possesses the prospect of industrial applications, by certain technological means, can be suspended by suspending agent, oil of excipient
Agent, water dispersible granules, wettable powder, effervescent tablet, granulae effervescentes etc. are easy to the formulation agriculturally used.
The present inventor has made intensive studies to foramsulfuron, halosulfuronmethyl, atrazine mixture, finds formamide sulphur
Grand, halosulfuronmethyl, atrazine mixture have Synergistic response, especially to eleusine indica (Eleusine indica), barnyard grass
(Echinochloa crusgalli), the rhizome of nutgrass flatsedge (Cyperus rotundus L.) have obvious Synergistic to respond.
The content of the invention
It is an object of the invention to solve the deficiency of existing herbicide, there is provided one kind has synergistic function, expands and kill
Grass spectrum, the Herbicidal combinations for the corn field that use cost is low, prevention effect is good.
The technical scheme is that：A kind of Herbicidal combinations, by effective constituents A, B, C and suitable insecticides adjuvant group
Into wherein effective constituents A is foramsulfuron, B is halosulfuronmethyl, C is atrazine, and effective constituents A, B, C are in the composition
Percentage by weight be respectively 1%~20%, 1%~20%, 1%~50%, remaining is insecticides adjuvant.
Described Herbicidal combinations those skilled in the art can be aided in from suitable pesticidal preparations according to known methods
Composition, excipient suspending agent, dispersible oil-suspending agent, water dispersible granules, wettable powder, effervescent tablet, granulae effervescentes etc. is adapted to
The formulation agriculturally used.
The processing technology of the various preparations of Herbicidal combinations of the present invention is prior art, can have been become according to different situations
Change.
The insecticides adjuvant used in Herbicidal combinations of the present invention include solvent, emulsifying agent, wetting agent, stabilizer, dispersant,
Disintegrant, binding agent, thickener, pH adjusting agent, defoamer, antifreezing agent, filler, carrier etc. are beneficial to active ingredient in the formulation
Known substance that is stable and playing drug effect, all it is to be commonly used in pesticidal preparations or allow the various composition used, specific composition and use
Amount is determined according to recipe requirements by testing.
The frequency of administration and amount of application of Herbicidal combinations of the present invention change with crops, weeds, weather condition and had a small amount of
Change, can reach the purpose effectively prevented and treated by using appropriate dosage.
It is single or two that triple combination (i.e. foramsulfuron halosulfuronmethyl atrazine) of the present invention can solve herbicide
Deficiency when member uses, expand herbicide controlling spectrum, and composition has Synergistic response, especially to eleusine indica (Eleusine
Indica), barnyard grass (Echinochloa crusgalli), the rhizome of nutgrass flatsedge (Cyperus rotundus L.) have obvious collaboration
Synergy responds, and offer excellent fix can be prevented and kill off for corn field annual grassy weeds, especially to eleusine indica (Eleusine
Indica), barnyard grass (Echinochloa crusgalli), the corn of the rhizome of nutgrass flatsedge (Cyperus rotundus L.) dominant weed
Field, there is positive effect for the corn field weed comprehensive regulation.
