Embodiment 1
[0014] Example 1: Indoor bioassay of barnyardgrass with compound medicaments
[0015] Test Weed: Barnyardgrass.
[0016] Test method: using the greenhouse pot method. The soil used for the experiment was the soil specially used for the experiment, and no chemicals were applied to the collected soil plots. Put the special soil for the experiment into the flowerpot; place the flowerpot in a pot containing water, and use the bottom of the pot to infiltrate the soil to keep the soil moist. 35 barnyardgrass seeds were sown in flowerpots, covered with soil 0.5 cm after sowing, and soil spraying was carried out 24 hours after sowing, and each treatment was repeated 4 times. After the treatment, they were placed in the greenhouse for normal management, and the growth of barnyardgrass was observed regularly. The combined action of herbicidal compositions was evaluated using the Gowing method.

[0022] Example 2: Indoor determination of compound medicament on Diffusa japonicus
[0023] Test weed: Daffodil; Test method: Reference Example 1.
[0024] Result analysis:

[0027]
[0028] It can be seen from Table 2 that the compound compositions of bensulfuron-methyl, butachlor and clomazone have different combined effects on Diffusa. When the mass ratio of bensulfuron-methyl, butachlor and clomazone is, 0.1:5:10, 0.5:5:5, 0.5:15:10, 1.0:15:5, 1.0:30:10, 1.0 : 5:20, it is a synergistic effect, and the other ratios are an additive effect, especially, when the mass ratio of bensulfuron-methyl, butachlor and clomazone is 0.1:15:20, 0.1: At 30:5 and 0.5:30:20, E-E0 is above 9.0, which can also effectively reduce the dosage of active ingredients and slow down the generation of drug resistance.
