Embodiment

[0030] Example: Combined toxicity test of different proportions of fenflutrazone and chlorpyrazosulfuron-methyl.

[0031] 1.1 Drugs to be tested:

[0032] 97% of the original drug of oxentrazone and 96% of the original drug of chlorpyrazosulfuron were provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target:

[0034] purslane.

[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...

Abstract

The invention discloses a phytocidal composition. The mass ratio of effective components including topramezone and halosulfuron-methyl in the phytocidal composition is (1-50):(50-1), the total mass of the effective components including the topramezone and the halosulfuron-methyl in the phytocidal composition accounts for 1-80% of the mass of the whole preparation, and the remaining components of the phytocidal composition are auxiliary components allowably used and received in pesticides, and the dosage form of the phytocidal composition is missible oil, suspending agent, wettable powder, water dispersible granule, emulsion in water, microemulsion, granula, and microcapsule. The phytocidal composition is mainly used for preventing and extirpating annual warm-season gramineous weeds, broad leaf weeds and sedge weeds in wheat, corn, rice, sugarcanes and lawns.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing fentrazone and chlorpyrazosulfuron-methyl. Background technique [0002] Oxenzazone is a benzoyl pyrazolone herbicide, and its chemical name is [3-(4,5-dihydro-1,2-oxazol-3-yl)-4-formyl- 0-methylphenyl] (5-hydroxy-1-methylpyrazol-4-yl) ketone, post-emergence stem and leaf treatment is absorbed by roots, seedlings, and leaves, and is transmitted to the top and base of the plant to the meristem tissue, inhibits p-hydroxyphenylpyruvate dioxygenase, inhibits plastoquinone and indirectly inhibits carotenoid biosynthesis, chloroplast synthesis and function disturbance. It has a wide herbicidal spectrum and can control annual warm-season grass weeds and broad-leaved weeds with good effect and long-lasting effect. [0003] Clopyrazosulfuron-methyl is a novel sulfonic acid urea herbicide developed by Nissan Chemical Company and developed...
