Embodiment

[0030] Example: Combined toxicity test of different proportions of fenfentrazone and cyanazine.

[0031] 1.1 Drugs to be tested:

[0032] 96% of the original drug of fenfentrazone and 96% of the original drug of cyanazine were provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target:

[0034] barnyard grass.

[0035] 1.3 Experimental steps:

[0036]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...

Abstract

The invention discloses a weeding composition containing topramezone and cyanazine. The weeding composition is characterized by taking the topramezone and the cyanazine as effective components, and the mass ratio of the topramezone to the cyanazine is 1-70 to 70-1; in the preparation, the total mass of the effective components, namely the topramezone and the cyanazine accounts for 1-80 percent of the mass of the whole preparation; and other components in the weeding composition are pesticidally allowable and acceptable auxiliary components. The weeding composition can be in the form of missible oil, suspension agent, wettable powder, water diffusion particle, water emulsion, microemulsion, granules and micro capsules. The weeding composition is mainly used for preventing and removing various gramineous weeds and broad-leaf weeds.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing fenfentrazone and cyanazine. Background technique [0002] Fenfenpyrazone (Pyrazenone) is a triketone post-emergence stem and leaf treatment agent. The drug has high activity and extremely low dosage. It has a wide suitable period for post-emergence use, flexible use, and a wide herbicidal spectrum. A grassy weed and a broadleaf weed, the chemical name of fenflumezone is [3-(4,5-dihydro-1,2-oxazol-3-yl)-4-formyl-O-tolyl ] (5-hydroxyl-1-methylpyrazol-4-yl) ketone, its chemical structural formula is . [0003] Cyanazine is a selective systemic conduction herbicide with a broad-spectrum herbicide. It is suitable for controlling a variety of grass weeds and broad-leaved weeds in corn, pea, broad bean, potato, sugarcane, cotton and other crop fields. The chemical name of cyanazine is 2-chloro-4-(1-cyano-1-methylethylamino)-6-ethyla...
