Quinclorac belongs to HPPD inhibitors, and can be used for preventing and removing annual weeds in sorghum fields, corn fields and wheat fields. The mequintocet-mexyl has similar framework to that of the quintocet-mexyl, the herbicidal spectrum is similar to that of the quintocet-mexyl, and the activity is higher. Clethodim and methyl clethodim are known, and patent document CN 104557739B reports clethodim and methyl clethodim and their herbicidal activity. The structure of the clethodim and the methyl clethodim is as follows:
when R in the formula (1)1Is H, R2Is 2, 6-dimethylphenyl, R3Is CH3，R4、R5、R6、R7And R8When both are H, the compound of formula (1) is clethodim; when R in the formula (1)1Is CH3，R2Is 2, 6-dimethylphenyl, R3Is CH3，R4、R5、R6、R7And R8And when the total amount of the compounds is H, the compound shown in the formula (1) is the mequintocet-mexyl.

Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Example 1: and (3) measuring indoor toxicity of the topramezone and the quinocetone.
Test subjects: barnyard grass.
The test method comprises the following steps: a greenhouse potting method. On the basis of indoor initial measurement, a series of concentration gradients are respectively set for the sulfonepyraflufen, the clethodim and the composition. The indoor bioassay was carried out with water containing no drug, the same solvent and emulsifier as blank control. Repeating the treatment for 4 times, treating for 3 pots, sowing 20 full and uniform pre-pregermination weed seeds in each pot, performing soil spray treatment (with a crawler-type crop sprayer, spray pressure of 1.90kg/cm2, spray liquid amount of 450L/ha, and crawler speed of 1.50km/h) after sowing for 24h, and investigating fresh weight control effect of overground parts after 21 days.
Calculating the medicament ED50 value according to DPS software; calculating the virulence index and the cotoxicity coefficient (CTC) of the medicament according to the Sun Yunpei method. When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Measured virulence index (ATI) ═ (standard agent ED 50/test agent ED50) × 100; theoretical virulence index (TTI) ═ a agent virulence index × percentage of a in the mixture + B agent virulence index × percentage of B in the mixture; co-toxicity coefficient (CTC) × 100 [ measured toxicity index (ATI) of the mixture)/Theoretical Toxicity Index (TTI) of the mixture ].
