Abstract
The invention discloses a kind of Rapeseed Field herbicides special.It comprises active ingredient and auxiliary agent, and wherein active ingredient is by Quizalotop-ethyl, florasulam with 2,4-dichlorphenoxyacetic acid is composite forms, and the mass ratio of described Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid is 10-12:3-5:1; The content of described active ingredient is 15-75wt%.The present invention, by after composite to Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid, expands its fungicidal spectrum.Not only to grassy weed, there is good preventive effect, to broad leaved weeds such as ox chickweed, Herba Galii Teneri, mustard of cracking rice, Descurainia sophia, tongue of sparrow grass, Mazus japonicus, Veronicas, also there is good preventive effect, enhance drug resistance and crop safety simultaneously.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of Rapeseed Field herbicides special, belongs to field of agricultural production technologies.
Background technology
Rape, is pakchoi again, bitter dish, is the young stem and leaf of crucifer rape, and originate in China, color is dark green, and side, as Chinese cabbage, belongs to the mutation of Cruciferae Chinese cabbage.The South and the North is widely cultivated, and the four seasons all have for producing.The weeds of Rapeseed Field are divided into grassy weed and broad leaved weed.Grassy weed mainly contains amur foxtail, fescue, annual bluegrass, caput grass etc.Broad leaved weed mainly contains ox chickweed, Herba Galii Teneri, mustard of cracking rice, Descurainia sophia, tongue of sparrow grass, Mazus japonicus, Veronica etc.Existing wheatland weed killer herbicide mostly is single dose, and the herbicidal effect of single dose is poor, only can remove portion single variety weeds; Also have composite weed killer herbicide at present, but the broad spectrum activity of weeding is poor, cost, environmental pollution are larger.
Quizalotop-ethyl, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, molecular formula: C

4; Molecular weight: 372.8.Its mechanism of action is: absorbed by weeds cauline leaf, and Bidirectional Conduction up and down in plant corpus, is accumulated in top and intercalary meristematic, and T suppression cell fatty acid synthesizes, and makes weeds downright bad.It is a kind of novel dry land cauline leaf inorganic agent of high selectivity, has the selectivity of height, have good preventive effect to the grassy weed in broad leaf crop field between grassy weed and dicotyledonous crops.
Florasulam, chemical name: the fluoro-5-methoxyl group of 2', 6'-bis--8-fluorine [1,2,4] triazole [1,5-c] pyrimidine-2-sulfonanilide, molecular formula: C

3s.Florasulam is inner-adsorption conduction-type herbicide, can conduct to weeds complete stool, and thus herbicide is thorough, can not recur.Florasulam broad weed-killing spectrum, can prevent and kill off the most of broad leaved weed of wheatland, comprises the difficult anti-weeds such as clearvers, corn gromwell and has extraordinary inhibitory action.
2,4-dichlorphenoxyacetic acid, also claims 2,4-to drip or 2,4-D.Plant growth regulator and weed killer herbicide.Use can enter in plant corpus from root, stem, leaf as weed killer herbicide, degraded slowly, therefore can accumulate finite concentration, thus interference plant corpus internal hormone balance, destroy nucleic acid and proteometabolism, promote or suppress some organ growth, make the distortion of weeds cauline leaf, stem foot is thicker, swollen splits.
Summary of the invention
The invention provides a kind of Rapeseed Field herbicides special, this weed killer herbicide is by Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid is composite forms, and its fungicidal spectrum is wide, and use safety.
Technical scheme of the present invention is: a kind of Rapeseed Field herbicides special, comprise active ingredient and auxiliary agent, wherein active ingredient is by Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid is composite to be formed, the mass ratio of described Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid is 10-12:3-5:1; The content of described active ingredient is 15-75wt%.
Preferably, the mass ratio of described Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid is 10:4:1.
Above-mentioned weed killer herbicide can add auxiliary agent and make missible oil, microemulsion, wetting powder etc.
The formula of missible oil is (weight ratio): Quizalotop-ethyl 10-12%, florasulam 3-5%, 2,4-dichlorphenoxyacetic acids 1%, emulsifier 15-25%, cosolvent surplus.
Described emulsifier is the mixture of one or more in dodecyl sodium sulfonate calcium, castor oil polyoxyethylene ether, aliphatic acid polyethenoxy ether, polyoxyethylene nonylphenol ether, polyoxyethylene aliphatic alcohol ether.
Described cosolvent is the mixed solvent of one or more in dimethylbenzene, toluene, dimethyl formamide, solvent naphtha.
Optimization formula is (weight ratio): Quizalotop-ethyl 10%, florasulam 4%, 2,4-dichlorphenoxyacetic acid 1%, dodecyl sodium sulfonate calcium 12%, castor oil polyoxyethylene ether 8%, dimethylbenzene (cosolvent) surplus.
Preparation method: first Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid are dissolved in cosolvent, then add emulsifier, obtain cream preparation.
Using method: rape early tillering stage dispenser, 35-45 milliliter/mu, does the spraying of even cauline leaf.
The invention has the beneficial effects as follows:
(1) the present invention is by after composite to Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid, expands its fungicidal spectrum.Not only to grassy weed, there is good preventive effect, to broad leaved weeds such as ox chickweed, Herba Galii Teneri, mustard of cracking rice, Descurainia sophia, tongue of sparrow grass, Mazus japonicus, Veronicas, also there is good preventive effect.
(2) the present invention enhances its drug resistance and crop safety by composite to Quizalotop-ethyl, florasulam and 2,4-dichlorphenoxyacetic acid.
(3) the present invention applies 2,4-dichlorphenoxyacetic acid, use can enter in plant corpus from root, stem, leaf as weed killer herbicide, degraded slowly, therefore can finite concentration be accumulated, thus interference plant corpus internal hormone balance, destroy nucleic acid and proteometabolism, promote or suppress some organ growth, making that the distortion of weeds cauline leaf, stem foot are thicker, swollen to be split.It as the growth regulator of corn, can promote corn growth, bears fruit, play the effect of volume increase simultaneously.
