No. 54091-06-4, available from Kumiai).

The safeners are preferably bisfenoxazole acid (CAS: 163520-33-0), cyprosulfamide (CAS: 221667-31-8), pyraclostrobin (CAS: 135590-91-9), quinoquine (CAS: 135590-91-9) : 99607-70-2), one or more of gibberellic acid (CAS: 7-06-5), furilazole (CAS: 121776-33-8), metcamifen (CAS: 129531-12-0).

The compositions of the present invention may be diluted or used directly by the user prior to use. Its preparation can be prepared by the usual processing method, that is, after mixing the active substance with a liquid solvent or a solid carrier, and then adding one or more of surfactants such as dispersing agent, stabilizer, wetting agent, adhesive, defoaming agent, etc. kind.

The specific formulations of the herbicidal composition are dispersible oil suspensions, water suspensions, suspoemulsions, wettable powders, emulsifiable concentrates, water dispersible granules (dry suspensions), water emulsions, and microemulsions.

Briefly, the compositions of the present invention can be mixed with solid and liquid additives conventionally used in prior art formulations.

The present invention also provides a use of the herbicidal composition for controlling weeds; and a method for controlling unwanted plant growth, comprising applying the herbicidal composition to plants, plant parts, plant seeds or The area where plants grow.

In addition, the compositions of the present invention can be applied by spraying to the foliage of the plants to be treated, ie to weeds, especially to surfaces that are infested or susceptible to infestation.

When the herbicidal composition of the present invention is applied, an unexpected synergistic effect is obtained, and the herbicidal activity is more pronounced than the expected sum of the activities of the individual herbicides, and the activity of the individual herbicides. The synergistic effects are reduced application rates, a wider weed control spectrum, and faster and longer lasting herbicidal action, characteristics that are desirable in weed control practice. In terms of the described properties, these new compositions are clearly superior to existing herbicides, resulting in reduced use and more environmentally friendly.

The synergistic herbicidal composition of the present invention also has the following advantages:

(1) The composition of the present invention is environmentally friendly and is easily degraded in the environment.

(2) The herbicidal composition of the present invention has low cost and convenient use, and its popularization and application have huge economic and social benefits.

B) Drug efficacy test

Post-emergence stem and leaf spray treatment:

1) Test conditions

1.1), test target

The duck tongue grass, barnyard grass, and exotic sedge were collected from the outpost farm in Heilongjiang; crabgrass and multiflora ryegrass were collected from Huai'an, Jiangsu; The above weeds were cultivated in pots, using a 180х140mm plastic nutrient bowl, placed in an enamel plate, with the surface soil (4/5 places) collected from the farmland and air-dried and screened. The soil humidity was initially controlled at 20%. Weed seeds with plump and uniform grains were soaked in warm water at 25°C for 6 hours, germinated in a biochemical incubator (dark) at 28°C, and the weed seeds that had just exposed white were evenly placed on the soil surface. -1cm.

1.2), culture conditions

It is carried out in a controllable solar greenhouse, with a temperature of 20 to 30°C, natural light, and a relative humidity of 57% to 72%. The soil type is loam, the organic matter content is 1.63%, pH=7.1, alkaline hydrolyzable nitrogen 84.3 mg/kg, available phosphorus 38.5 mg/kg, available potassium 82.1 mg/kg.

1.3), instruments and equipment

3WP-2000 walking spray tower, Nanjing Agricultural Machinery Research Institute, Ministry of Agriculture. GA10 type 1/10,000 electronic balance (Germany); ZDR2000 intelligent data recorder (Hangzhou Zeda Instrument Co., Ltd.); SPX type intelligent biochemical incubator (Ningbo Jiangnan Instrument Factory).

2) Experimental design

2.1), reagents

The required active ingredients, diflufenazone, cyclofenazone, diflufenazone, and triflufenazone are produced by the company, and others are purchased by the reagent company. The original medicines were all made of acetone as solvent, diluted with 0.1% emulsifier Tween-80 aqueous solution, and diluted with current use.

2.2), test processing

2.2.1), dose setting

When determining the ratio or content of A and active ingredient B, the function characteristics and toxicity of the two agents should be measured, and the main purpose of use of the formula should also be considered. In this study, on the basis of the preliminary test, the single and mixed dosages of A and B active ingredients are shown in the table respectively. The water containing no drug, the same solvent and emulsifier was used as a blank control.

2.2.2), test repetition

Each treatment was repeated 4 times, with 3 pots per treatment, and 20 weed seeds were sown in each pot, with a total of 60 plants per treatment.

2.3), processing method

2.3.1), processing time and times

The test shared medicine once. When the weeds are in the 1-leaf stage, thin the seedlings, keep 15 weeds in each pot, keep 45 weeds in each treatment, and then continue to cultivate to 2-3 leaves for treatment.

2.3.2), use of instruments and methods of medication

The cultivated test materials were placed evenly on a platform with an area of 0.5m ² , and the stems and leaves of the 3WP-2000 walking spray tower were sprayed, and the spray volume was 30 kg/ha. The spray pressure is 0.3MPa. After all the liquid medicine is sprayed, close the air valve, open the spray tower door after 30 seconds, and take out the nutrition bowl. Then open the air valve, spray 50mL of water, and clean the spray pipe.

3) Test method

Use potted plants. See 1.1 for weed cultivation, and carry out with reference to "Pesticide Indoor Bioassay Test Guidelines for Herbicides". See 2.3.2 for the medication method, and the stem and leaf treatment method is adopted. After the treatment, they were transferred to the greenhouse for routine cultivation, and the water layer of 1-2 cm was always maintained during the experiment.

4) Data investigation and statistical analysis

4.1), investigation method

Using the absolute number investigation method, the whole seedlings of surviving weeds were cut off along the soil surface with a blade, and the fresh weight of the weeds was weighed with an analytical balance. For dead weeds, the fresh weight is zero.

4.2), investigation time and frequency

The investigation was conducted 20 days after the treatment, and a total of 1 investigation was conducted.

4.3), statistical analysis of data

The theoretical fresh weight inhibition rate (E0=X+Y-X*Y/100) of the mixed combination of each treatment was calculated by the Gowing method, and then compared with the measured inhibition rate (E) to evaluate the combined effect of the two on weeds. E-E0 values greater than 10% are synergistic effects, less than -10% are antagonistic effects, and between -10% and 10% are additive effects. And according to the actual control effect and herbicide characteristics, formula balance and other factors to determine the best ratio. In the formula, X is the fresh weight inhibition rate when the amount of active ingredient A is P; Y is the fresh weight inhibition rate when the amount of active ingredient B is Q.
