Abstract
The invention provides herbicide compound containing mesotrione and terbuthylazine and a preparation method thereof. The herbicide compound comprises mesotrione and terbuthylazine, agricultural emulsifier 1601 is adopted as the emulsifier, resin-based vegetable oil is adopted as the synergist, and the rest is oil suspension filler methyl oleate or suspending agent filler water. The resin-based vegetable oil is added as the synergist, so that the pesticide effect can be significantly improved. The compound has very significant synergistic effect compared with two type of single dosage, i.e. mesotrione and terbuthylazine. The overall pesticide effect is obviously better than the mixture of single dosage. The prevention effect of the herbicide compound to gramineous weeds is 80.1 percent to 99.6 percent; and the prevention effect of the herbicide compound to broad-leaved weeds is 88.9 percent to 100.0 percent. The integrated prevention effect of the mesotrione is 67.7 percent to 69.7 percent; the integrated prevention effect of the terbuthylazine is 49.5 percent to 53 percent; and the integrated prevention effect of the herbicide compound is 83.5 percent to 99.9 percent. The herbicide compound can be prepared into oil suspension and suspending agent.
Description
Technical field
The invention belongs to the agricultural herbicide technical field, relate to a kind of herbicidal composition and method for making that contains mesotrione, Garagard.
Background technology
Northeast is sealed weeding and the malignant weeds appearance such as drug effect relatively poor phenomenon, especially barnyard grass, Commelina communis, piemarker, the rhizome of nutgrass flatsedge generally occurred in North China's corn field at present, and corn yield has been caused very large impact.Mesotrione can be prevented and kill off the annual broad-leaved of corn field and part grassy weed.Garagard is before the interior suction selectivity seedling, herbicide after seedling.Root absorption is main, and cauline leaf absorbs seldom.Be applicable to corn, Chinese sorghum, sugarcane, tea place, rubber and orchard, nursery.
But, use separately mesotrione or Garagard single dose, exist the control grass to single, the problem such as whole control efficiency is poor.
Summary of the invention
Use mesotrione, Garagard single dose control grass to single in order to solve, the problem such as whole control efficiency is poor.The present invention proposes a kind of herbicidal composition and method for making that contains mesotrione, Garagard.
Constituent and the percentage by weight of the present invention proposes a kind of herbicidal composition that contains mesotrione, Garagard are as follows:
Mesotrione is 1～30, is preferably 5-10; Garagard is 2～30, is preferably 12-20; Emulsifier is farming breast 1601, and emulsifier is 6%;
,Synergist is 15%; All the other are filler, and the addition of filler makes the gross weight of all constituents of herbicidal composition be a hundred per cent; Described filler comprises oil-suspending agent filler or suspending agent filler, and the oil-suspending agent filler is methyl oleate, and the suspending agent filler is water;
The chemical name of mesotrione is 2-(4-mesyl-2-nitro-benzoyl) cyclohexane-1, the 3-diketone; Structural formula is as follows:
The chemical name of Garagard is 2-chloro-4 special fourth amino-6-ethylamino-1,3,5-triazines; Structural formula is as follows:
A kind of herbicidal composition that contains mesotrione, Garagard that the present invention proposes can be mixed with oil-suspending agent and suspending agent.
(1)The method for making of the oil-suspending agent of the present invention proposes a kind of herbicidal composition that contains mesotrione, Garagard
,Its step and condition are as follows: (1) joins abundant the stirring 30 minutes in the stirred tank according to the proportioning of described herbicidal composition with various raw materials, will shear simultaneously in the whipping process; (2) material that stirs after 30 minutes grinds by sand mill, and particle diameter D50 must not be greater than 8 microns; (3) adding of the material after the grinding is sheared in the still and was sheared 30 minutes; Obtain a kind of oil-suspending agent that contains the herbicidal composition of mesotrione, Garagard.
(2)The method for making of the suspending agent of the present invention proposes a kind of herbicidal composition that contains mesotrione, Garagard
,Its step and condition are as follows: (1) joins abundant the stirring 30 minutes in the stirred tank according to the proportioning of described herbicidal composition with various raw materials, will shear simultaneously in the whipping process; (2) material that stirs after 30 minutes grinds by sand mill, and particle diameter D50 must not be greater than 8 microns; (3) adding of the material after the grinding is sheared in the still and was sheared 30 minutes; Obtain a kind of suspending agent that contains the herbicidal composition of mesotrione, Garagard.
A kind of herbicidal composition that contains mesotrione, Garagard that the present invention proposes is used for the postemergence weed control of corn field, particularly removes various grass family and broad leaved weed in the corn field.
A kind of herbicidal composition that contains mesotrione, Garagard that the present invention proposes uses by the using method of existing weed killer herbicide, executes spraying by common method.
Beneficial effect:A kind of herbicidal composition that contains mesotrione, Garagard that the present invention proposes, the adding turpentine-based vegetable oil is synergist, can obviously improve drug effect.Compare with two kinds of single doses of mesotrione and Garagard and to have very significantly synergistic function.Whole drug effect is mixed significantly better than single dose.
Herbicidal composition low dosage of the present invention is found out from the table 6 of application test embodiment 6 control efficiency of grassy weed, 20% herbicidal composition of the present invention, and 360 g/has, minimum is 80.1%.In the time of 720 g/has, reach 99.6%.
Find out from the table 3 of application test embodiment 3,8% herbicidal composition of the present invention, 360 g/has is 88.9 % to the control efficiency of broad leaved weed.Find out from the table 6 of application test embodiment 6,20% herbicidal composition of the present invention, 720 g/has is 100.0 % to the control efficiency of broad leaved weed.
Integrated control effect aspect, the control efficiency of mesotrione component are between the 67.7%-69.7%; The control efficiency of Garagard component is between the 49.5%-53%.Composition integrated control effect of the present invention is between the 83.5%-99.9%.This shows, the control efficiency of herbicidal composition of the present invention obviously improves, and synergy is remarkable.
Herbicidal composition of the present invention has significantly improved the control efficiency to corn field weed, has reduced peasant's drug cost, has reduced the influence degree to environment, is that agricultural production needs the most.The present invention proposes a kind of filler turpentine-based vegetable oil of using in the herbicidal composition of mesotrione, Garagard of containing is as extracting in the Chinese pine timber, the raw material natural environmental-protective, and resource is renewable.Permeability is strong because turpentine-based vegetable oil has in agricultural chemicals, plate-out ability is strong, resistance of rainwater washing against, can obviously improve drug effect, has thoroughly solved pesticidal preparations in a large number with an organic solvent, environment is produced the problem of severe contamination.A kind of herbicidal composition that contains mesotrione, Garagard that the present invention proposes prevent and kill off 1 year living broadleaved herb and grassy weed synergy obvious, especially to malignant weed special efficacys such as barnyard grass, the rhizome ofs nutgrass flatsedge, and quick-acting is obvious, can reduce the medicament usage amount.
