Abstract
The invention discloses herbicide for the stem and leaf treatment of hemerocallis fulva. The herbicide comprises the active ingredients including quizalofop-p-ethyl and fluroxypyr-mepthyl in the weight ratio of 2 to 7:8, wherein the active ingredients account for 25 to 37.5 percent of the total weight of the herbicide composition. The herbicide disclosed by the invention has a good herbicidal effect on hemerocallis fulva fields, is safe to crops, and is a compound herbicide with an ideal effect on preventing and controlling weeds in hemerocallis hybridus fields at present.
Description
Technical field
The present invention relates to pesticide herbicide technical field, specifically a kind of weed killer herbicide for the process of tawny daylily cauline leaf.
Technical background
Chemical herbicide application technology improves constantly in the development of China, by the developing test of more than 60 years, weed killer herbicide defines and comparatively improves ripe Chemical Weeding System on paddy rice, wheat, soybean, cotton, corn and part economic crops, achieves significant economic benefit and social benefit.But at chemical weeding particularly some short open country Perennial Flowers, because of its strange land introduce a fine variety, the reason such as to plant for many years, cause in ground, garden and mostly be perennial root or the malignant weeds such as cogongrass, Mao Xiang, ivy glorybind, field bindweed, kitchen garden, these weeds are with radical bud and seed amount reproduction, growth rate is very fast, and acrial part has been removed under ground portion germinates again new tender shoots out very soon, artificial weeding is difficult to be eradicated.Again because perennial root plant is shorter, while some nonselective herbicide managements of weeds, poisoning can be caused to Perennial Flowers, not have ripe technology to be used for reference application.
In recent years, use 33% pendimethalin missible oil after the people such as Shandong Agricultural University Du E report hemerocailis middendorffi transplant planting, 72% isopropyl methoxalamine missible oil carries out the test of soil treatment management of weeds and carry out cauline leaf spraying with the sethoxydim of variable concentrations, fluazifop and prevent and kill off the experimental study of potted plant hemerocailis middendorffi grassy weed, but, the ground mixed life such as grassy weed and broad leaved weed often of production garden, need to expand herbicide spectrum, reach the object of effective management of weeds.
Summary of the invention
Object of the present invention is just to provide a kind of weed killer herbicide for the process of tawny daylily cauline leaf, can prevent and kill off the annual and perennial grass family in tawny daylily field, can prevent and kill off annual and perennial broadleaf weed again, and to tawny daylily and succession crop safety.
The technical scheme that the present invention takes:
A kind of weed killer herbicide for the process of tawny daylily cauline leaf, the Quizalotop-ethyl (2-[4-(6-chloro-2-quinoxaline oxygen base)-phenoxy group] ethyl propionate) of its active component to be mass ratio be 2 ~ 7:8 and the different monooctyl ester of fluroxypyr (the fluoro-pyridine of amino-3, the 5-bis-chloro-6-of 4--2-fluoroacetic acid).
Described active component accounts for 25 ~ 37.5% of herbicidal composition gross weight, suitably can adjust according to the proportioning of amount of application when using and active component.
The processing of present composition preparation adopts Conventional processing methods to make pesticidal preparations, and the preferred formulation of the present invention is emulsifiable concentrate.
The quality group of the preferred emulsifiable concentrate of the present invention becomes: Quizalotop-ethyl 5-17.5%, and the different monooctyl ester 20% of fluroxypyr, emulsifier 3-10%, solvent complements to 100%.
The present invention is by after two kinds of medicament mixtures, annual and the perennial grassy weed such as barnyard grass, green foxtail, Ma Tang, alkali grass, kitchen garden, field bindweed, ivy glorybind and annual and perennial broadleaf weed can be prevented and treated, expand herbicide spectrum, reach the object of effectively control, reduce the using dosage of medicament in field simultaneously, save Financial cost, reduce medicament to the pollution of environment, and improve the control efficiency to perennial root and malignant weed.
Weed killer herbicide of the present invention can reach good herbicidal effect to tawny daylily field, and to crop safety, is the desirable complex weedicide of current hemerocailis middendorffi field weed control effect.
Embodiment
Embodiment 1
Quizalotop-ethyl 5%, the different monooctyl ester 20% of fluroxypyr, polyoxyethylene fatty acid ester 3%, dimethylbenzene complements to 100%, stirs the different monooctyl ester emulsifiable concentrate of formation 25% Quizalotop-ethyl fluroxypyr.
Embodiment 2
Quizalotop-ethyl 11%, the different monooctyl ester 22% of fluroxypyr, polyoxyethylene nonylphenol ether 5%, acetone complements to 100%, stirs the different monooctyl ester emulsifiable concentrate of formation 33% Quizalotop-ethyl fluroxypyr.
Embodiment 3
Quizalotop-ethyl 17.5%, the different monooctyl ester 20% of fluroxypyr, neopelex 10%, dimethylbenzene complements to 100%, stirs the different monooctyl ester emulsifiable concentrate of formation 37.5% Quizalotop-ethyl fluroxypyr.
These are only preferred embodiment of the present invention; not limit the scope of the invention; the present invention also available conventional pesticide formulation method makes other formulations as suspending agent, aqueous emulsion, wetting powder etc., and material conventional in kind other pesticidal preparations all available of solvent, emulsifier and defoamer replaces.
Concrete technology implementation result: in the weeds 2-6 leaf phase, uses the present invention 37.5% Quizalotop-ethyl fluroxypyr different monooctyl ester missible oil dosage 225ml/hm
2, 450ml/ hm
2, 675ml/ hm
2, 900ml/ hm
2, be watered 450kg/ hm
2, after spray medicine 7,15,30d investigates weeds strains number, calculate strain preventive effect, observe hemerocailis middendorffi by poisoning situation and weed growth situation simultaneously.The herbicidal effect of dispenser after 30 days the results are shown in Table 1.
After medicine, 15d, 30d, 60d observe weed killer herbicide on the impact of hemerocailis middendorffi plant height, blade, flower, and 90d investigates the tiller number of each process.
By range estimation, after hemerocailis middendorffi dispenser 30d, middle low concentration 225ml/hm
2, 450ml/ hm
2, 675ml/ hm
2time there is no symptom of chemical damage, only high concentration 900ml/ hm
2time there is radical leaves yellow, the phenomenon such as withered.During investigation result after test 60d, 90d proves, during low concentration, hemerocailis middendorffi can normal growth and tillering.Visible use drug concentration of the present invention is at 450 ~ 675ml/ hm
2can reach good herbicidal effect, and to crop safety, be the desirable complex weedicide of current hemerocailis middendorffi field weed control effect.
