The compound herbicide adopts the compound use of the ketone herbicide, the safener, various herbicides and the adsorption additive, not only can expand the weeding range and improve the control effect, but also can effectively prolong the suitable pesticide application period and effectively remove gramineous weeds and broadleaf weeds in each growth period in the corn field.
Description
Technical Field
The application relates to the field of pesticides, in particular to a herbicide and a preparation method thereof.
Background
Corn is an annual herbaceous plant of corn of the family Gramineae, is an important food crop and feed crop in China, is widely planted in various regions of the south and the north, and has a wide planting area in China. But weeding is very critical in the planting process of corn.
The common weeds in the corn field are various in types, and comprise various annual grasses (such as green bristlegrass, crabgrass and the like), perennial grasses (such as spiny sedge, endive and the like) and broadleaf weeds (such as amaranthus retroflexus, purslane and the like), the occurrence and seedling emergence peak periods of different types of weeds are different, the seedling emergence peak period of the annual weeds is from late 4 months to late 5.4 months, the seedling emergence peak period of the biennial weeds is from late 5.4 months, the seedling emergence peak period of the perennial weeds is from late 5.4 months to late 5.4 months, and the seedling emergence peak period of the perennial weeds is from late 5.4 months, and the corn field is a weed peak period from 4 months to 5.4 months.
In the actual process of corn field production, the use of chemical herbicide is an important measure for reducing the weeds in corn and ensuring the high and stable yield of corn, and is also the most economic and effective means for preventing and killing weeds in farmland, however, the common herbicide on the market has the pesticide effect of 10-15 days at present, the treatment time is short, and the weeds in each growth cycle cannot be effectively inhibited in the effective time after the pesticide is spread.
Disclosure of Invention
In order to solve the problem of short weeding effect of the existing herbicide, the application provides a herbicide and a preparation method thereof.
In a first aspect, the present application provides a herbicide, which adopts the following technical scheme:
a herbicide comprises an active component A, an active component B, an active component C and an adsorption aid;
the active component A is selected from one or more of mesotrione, isoxaflutole, tembotrione, topramezone, sulfontopyrazole and sulcotrione;
the active component B is selected from one or more of isoxadifen, mefenpyr, cloquintocet-mexyl and gibberellic acid;
the active component C is selected from one or more of thiencarbazone-methyl, bromoxynil octanoate, atrazine and terbuthylazine.
By adopting the technical scheme, mesotrione, isoxaflutole, tembotrione, topramezone, sulfonylopyrazole and sulcotrione belong to triketone herbicides, the triketone herbicides have a wide weed control spectrum and are environment-friendly, broad-leaved weeds in corn fields can be effectively controlled, and part of gramineous weeds in corn fields, such as barnyard grass, green bristlegrass, large-area commercial popularization and use are also controlled, but the herbicides can kill crops per se generally, so that the safeners such as isoxadifen, mefenpyr, cloquintocet, gibberellic acid and the like are compounded for use, the plants can be protected, and the pesticide effect can be increased; because each herbicide has specific selectivity and a weed control spectrum, a single herbicide cannot completely control all weeds in the whole growth period of crops, and the biological communities of farmland weeds are various, long-term use of the single herbicide can not only cause succession of the weed communities but also cause drug resistance of the weeds, so that the application measures of nicosulfuron, thiencarbazone-methyl, ametryn, atrazine and terbuthylazine are adopted, the weeding range can be enlarged, the control effect is improved, pesticide residues are reduced, the resistance of the weeds is delayed, the suitable application period can be effectively prolonged, the grassy weeds and broad leaf weeds in each growth period in a corn field can be effectively removed, and simultaneously, the pesticide effect time of the triketone herbicide is about 15.4d on average and is cleared up in the soil, the inhibition effect of the grassy weeds growing in the later period is weak, so that an adsorption auxiliary ingredient is added, the adsorption amount of the herbicide in the soil is increased, the herbicide clearing time is delayed, the pesticide effect is further prolonged, the herbicide effect is effectively increased, the weed in each time period in the corn field is inhibited, and the crop yield is increased.
Preferably, when the active component A is tembotrione, the active component B is isoxadifen, and the active component C is bromoxynil octanoate.
By adopting the technical scheme, the tembotrione is mainly used for weeding in corn fields, has high activity, low residue, environmental protection, safety to animals and broad-spectrum weeding activity, can prevent and kill off various broadleaf weeds and gramineous weeds in the corn fields, is effective to partially resistant weeds, and has the effects of expanding a weed spectrum, improving the prevention and killing effect, reducing pesticide residue and delaying the occurrence and development of drug resistance and drug resistance of weeds by reasonable compounding or mixing with bromoxynil octanoate.
Preferably, the mass part ratio of the active component A to the active component B to the active component C to the adsorption aid is 5.4-7.
By adopting the technical scheme, the herbicide is obtained according to the proportion and has the optimal weeding effect.
Preferably, the adsorption aid is prepared by the following steps:

TABLE 3 (50 d later plant control effect%)
When the pesticide is sprayed for 50 days, the plant control effect is reduced to a certain extent compared with 18 days, but the difference of the plant control effect of the adsorption aid is far smaller than that of the plant control effect of the plant without the adsorption aid, as can be seen by combining examples 1-7 and comparative example 1 and combining tables 2 and 3.
It can be seen from the combination of examples 1 to 7 and table 2 that the herbicide added with the adsorption adjuvant has better early-stage plant control effect than the herbicide without the adsorption adjuvant, and the adsorption adjuvant can not only delay the digestion of the herbicide, but also effectively improve the weeding effect of the herbicide.
By combining example 1, example 8 and comparative example 1 with tables 2 and 3, it can be seen that the herbicidal effect of the herbicide is greatly improved by the combined use of the methylated vegetable oil and the adsorption adjuvant.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
