Embodiment 1

[0015] Embodiment 1: indoor pot test

[0016] Test method: Fill a plastic bowl with holes in the bottom with air-dried fine soil, and place it in a plastic box with sufficient water. The air-dried fine soil absorbs water through soil osmosis, and sows after the water is saturated. The weed barnyardgrass is sown in plastic bowls, 30 grains / bowl. After sowing, cover with 0.2-1.0cm of fine soil according to the size of the seeds, and place them in a solar greenhouse for cultivation. Water every other day to keep the soil moist. Dingmiao when the weeds emerge neatly. When the weed barnyardgrass grows to the 2-3 leaf stage, spray the stems and leaves.

[0017] Treatment and investigation methods: Spray stems and leaves at the 2-3 leaf stage of weeds, and regularly observe the damage of weeds after spraying. 21 days after application, the fresh weight of aboveground parts of weeds was investigated, and the fresh weight inhibition rate was calculated.

[0023] Embodiment 2 field control effect test

[0024] Test drug:

[0025] Formulation 1: 22.8% quinclomidone penoxsulam oxaziclozone dispersible oil suspension concentrate

[0026] quinclomid 20%, penoxsulam 1.2%, oxaziculone 1.6%, Nongru 500 5%, soil temperature 805%, sodium lauryl sulfate 4%, organic silicon 3%, bentonite 4 %, methyl oleate makes up 100%.

[0027] Formulation 2: 26% quinclomidone penoxsulam oxaziclozone dispersible oil suspension concentrate

[0028] 20% quinclomid, 2% penoxsulam, 4% oxaziculone, 4% Nongru 500, 6% soil temperature 80, 5% sodium lauryl sulfate, 2% organic silicon, bentonite 3.5%, methyl oleate makes up 100%.

[0029] Test weeds: Weeds in paddy fields: barnyardgrass, stephenia, sedge, and bermudagrass.

[0030] Test method: In the 1-3 leaf stage of weeds, spray the stems and leaves once, and investigate the fresh weight control effect after 21 days. Control effect (%)=[(fresh weight of weeds in clear water control group-fresh weight of ...

Abstract

The present invention provides a herbicidal composition containing quinocazone, the active components comprising quinocazone, penoxsulam and oxaflutole; and quinocazone, penoxsulam and The mass ratio of oxaflutole is 5-20:0.3-0.9:0.4-1.5; the composition of the invention has obvious synergistic effect, and the control effect is higher than that of a single agent; it can be used for the control of annual weeds in paddy fields.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, and in particular relates to a herbicidal composition containing quinclodone and an application thereof. Background technique [0002] Chloroquinone is a new type of herbicide with dual mechanism of action in paddy fields. It also has soil and stem and leaf treatment activity. It has good effect on paddy fields such as barnyardgrass, crabgrass, clove, and snakehead sausage. It has fast action speed, It has the advantages of broad herbicidal spectrum and high safety. Chloroquine can penetrate into the plant through the surface of stems and leaves, and can also be absorbed through roots. Its mode of action is absorption from stems, leaves and roots, and absorption from stems and leaves is the main mode of action. The results of indoor activity test and field efficacy test show that 20% quinclozone dispersible oil suspension concentrate has higher activity and better control effect on barnyardgr...
