Embodiment

[0030] Example: Combined toxicity test of different ratios of propasulfuron-methyl and saflufenacil.

[0031] 1.1 Drugs to be tested:

[0032] 97% of the original drug of Probensulfuron-methyl, 96% of the original drug of saflufenacil, the above-mentioned original drugs are provided by the R&D Department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target:

[0034] Daughter.

[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 da...

Abstract

A weeding composition is disclosed. The weeding composition comprises effective ingredients, namely propoxycarbazonesodiurn and saflufenacil, and the mass ratio of propoxycarbazonesodiurn to saflufenacil is 1-50:50-1. The effective ingredients propoxycarbazonesodiurn and saflufenacil in the preparation account for 1%-80% of the mass of the whole preparation, and the rest is auxiliary ingredients which are allowed to be used and accepted in a pesticide. Dosage forms of the weeding composition include missible oil, a suspending agent, wettable pulvis, water dispersible granules, an emulsion in water, a micron emulsion, a particulate agent and microcapsules. The weeding composition has wide weed control spectrum and is mainly used to control and remove gramineous weeds in cereal crops such as wheat, barley and rye, including annual weeds, part of perennial weeds and most broad leaf weeds.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing propasulfuron-methyl and saflufenacil. Background technique [0002] Probensulfuron-methyl is a new type of sulfonylurea herbicide developed by Bayer AG of Germany. Its chemical name is 2-(4,5-dihydro-4-methyl-5-keto-3-propoxy-1H-1,2,4-triazol-1-yl)formylaminosulfonylbenzene Methyl formate sodium salt. Probensulfuron-methyl is mainly used for post-emergence stem and leaf treatment, mainly for the control of gramineous weeds in cereal crops such as wheat, barley, and rye fields, including annual weeds and some perennial weeds such as oats, oats, and wind. Bentgrass, Thatch, Goose View Grass, Abiragrass, Bromegrass that are difficult to remove, and some broad-leaved weeds, white chestnut and blue cabbage, etc. [0003] Saflufenacil is a uracil herbicide developed by BASF. Its chemical name is N-[2-chloro-4-fluoro-5-(3-methyl-2,6...
