Embodiment 1

[0014] Example 1: Indoor bioassay of compound medicament on barnyardgrass

[0015] Weeds tested: barnyardgrass.

[0016] Test method: use the greenhouse pot method. The soil used for the test is the soil specially used for the test, and no chemicals are applied to the soil plots collected. Put the special soil for the test into the flower pot; place the flower pot in a pot filled with water, and keep the soil moist by using the bottom of the pot to irrigate. 35 barnyardgrass seeds were sown in flowerpots, covered with soil 0.5cm after sowing, seedlings were established during the 2-leaf period, and 20 barnyardgrass with the same growth potential were kept in each pot until they grew to the 3-leaf stage. A series of single doses of different concentrations and different combinations of mixtures were prepared, and the stems and leaves were sprayed with a potter spray device, and each treatment was repeated 4 times. After treatment, they were placed in the greenhouse for norma...

Embodiment 4

[0035] Example 4 Determination of the efficacy of compound medicaments on weeds in non-cultivated land

[0036] Weeds: barnyardgrass, daughter of a daughter, bermudagrass, special-shaped sedge.

[0037] Application method: set up 2 chemical treatments, 1 blank control, and repeat 3 times; the area of ​​each plot is 25m2, arranged randomly. Spray the stems and leaves with a sprayer. 14 days after spraying, the fresh weight control effect of weeds was investigated.

[0038] Result analysis: the compound composition of glyphosate or glufosinate-ammonium, fluorfen-propargyl and oxyfluorfen has a good control effect on weeds in non-cultivated land.

Abstract

The invention provides a ternary weeding composition. Active ingredients of the ternary weeding composition comprise an active ingredient A, an active ingredient B and an active ingredient C. The active ingredient A is glyphosate or glufosinate-ammonium, the active ingredient B is flumioxazin, and the active ingredient C is oxyfluorfen. The mass ratio of the active component A to the active component B to the active component C is 1-100: 0.1-30: 0.1-20. The weeding composition disclosed by the invention can be used for preventing and removing weeds in uncultivated areas and has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition comprising glyphosate or glufosinate-ammonium, fluflumecil propargyl and oxyfluorfen and application thereof. Background technique [0002] Glyphosate is a systemic conduction type herbicide with good systemic and conduction properties. It is mainly absorbed through the green part of the weed and quickly transmitted to all parts of the plant, killing the weed by its roots. [0003] Glufosinate-ammonium is an acid herbicide, an inhibitor of glutamine synthesis, a non-selective contact herbicide with partial systemic action, within a short period of time after application, the ammonium metabolism in the plant is in disorder, and the ammonium ion of the cytotoxic agent is in the Accumulation in plants, at the same time, photosynthesis is severely inhibited to achieve the purpose of weeding; it has a better control effect on non-cultivated land weeds ...
