Embodiment

[0032] Example: Combined toxicity experiment of different proportions of acesulam and florasulam.

[0033] 1.1 Drugs to be tested:

[0034] 96% of acesulam technical and 96% of florasulam technical, all of which are provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0035] 1.2 Test target:

[0036] Pig's calamity.

[0037] 1.3 Experimental steps:

[0038] Potted stem and leaf treatment method (NY / T1155.4-2006): put quantitative soil in a plastic pot with a height of 6 cm and a diameter of 9 cm, sow 15-20 grains of the target weed seeds in the plastic pot, and cover with 0.5 After the weeds grow to the 2-4 leaf stage, the stems and leaves are sprayed with 1 mL of liquid per pot, and each treatment is repeated 4 times, and the treatment without chemicals is set as control. After the treatment, the plants were cultured in the greenhouse, and the growth of the target weeds was regularly observed. After 15 days, the symptoms and growth inhi...

Abstract

The invention discloses a weeding composition containing pyroxsulam and florasulam. The mass ratio of the effective components of pyroxsulam to florasulam in the weeding composition is equal to (1-70): (70-1), the total mass of the pyroxsulam and florasulam in the weeding preparation accounts for 1%-80% of the whole preparation mass, and the balance is allowable and acceptable auxiliary components in a pesticide. The weeding composition can be in the form of missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water, microemulsion, granules, or micro capsules. The weeding composition is mainly used for preventing and killing broad leaf weeds and grassy weeds in a wheat paddock.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing acesulfame and florasulam. Background technique [0002] Pyxesulfame is a sulfonamide systemic conduction type, selective post-emergence herbicide in winter wheat fields, with broad herbicidal spectrum, high herbicidal activity and fast drug effect. Pyrosullam has a good control effect on gramineous weeds such as brome, kanko, Japanese kanko (including resistant kanko, resistant japonica), hard grass, etc. Wild geranium and other broad-leaved weeds have better control effect. The chemical name of acesulfame is N-(5,7-dimethoxy[1,2,4]triazol[1,5-α]pyrimidine-2-methoxy-4-(trifluoromethyl )-3-pyridinesulfonamide, its chemical structural formula is [0003] . [0004] Flumesulam is a super-efficient herbicide of the triazolopyrimidine sulfonamide class, and florasulam is a systemic conduction herbicide, which can be transmit...
