Background
Due to the long-term large amount of single unreasonable use of the herbicide, the control effect of the herbicide is obviously reduced, and meanwhile, resistant weeds are generated. The problem of herbicide resistance has become a global challenge.
In general, weed resistance occurs, and some resistant weeds or genetic types with resistance are retained and can be propagated to form a larger population. Taking barnyard grass as an example, each plant can produce 70 ten thousand seeds, which can be spread over a large area very effectively. From the field expression form, because one or the same type of herbicide is used for a large area or for a long time, the sensitivity of the originally sensitive weeds to the herbicide is reduced, so that the control effect is difficult to achieve by using the conventional dosage.
The herbicide is selected by competition, under the selection pressure of the herbicide, the gene in the weed body is mutated or the gene expression is changed, so that the detoxification capability of the herbicide is improved or the affinity of the herbicide and an action site is reduced, and the mutant generating the drug resistance finally generates a larger drug-resistant population along with the propagation and development of drug-resistant individuals. The herbicide is used singly in a large amount and in an excessive amount for a long time, and the drug resistance of the weeds is a necessary result. However, the rate of resistance formation is influenced by the characteristics of the herbicide, the biological characteristics of the weeds, the cultivation method, and other factors.
Herbicide resistance is a global challenge. The design can reduce the use cost, delay the weed resistance, is safe to the environment and can effectively solve the problem of resistant weeds in the current corn field.

Watering is carried out regularly to keep the soil humidity except that the watering can not be carried out 1-2 days after the pesticide spraying.
The weeding effect calculation method comprises the following steps:
the test results are shown in table 3.
TABLE 3
As can be seen from the results in table 3, the composition containing the xaflufen and terbuthylazine as active ingredients showed significant control effect on the grassy weeds, such as green bristlegrass, large crabgrass, broadleaf weeds, piemarker and small gooseberry.
The preferred embodiments of the present invention have been described above in detail, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention, including combinations of various technical features in any other suitable way, and these simple modifications and combinations should also be regarded as the disclosure of the invention, and all fall within the scope of the invention.
