Embodiment Construction
[0031]In order to make the technical solutions, objectives and advantages of the present invention clearer, the present invention is described with the following specific examples, but the present invention is not limited to these examples. The effect experiment of the present invention adopts the mode of field test, and unless otherwise specified, the ratios mentioned below are all ratios of parts by mass.
[0032] field efficacy test
[0033] The test was carried out in the wheat field test base in Henan Province. The soil fertility was consistent and medium. The humidity was moderate during the test. The main weeds in the test site were pigtails, brome, etc., and the weeds were evenly distributed. The test results are as follows:

Abstract
A weeding composition containing tribenuron methy mesosulfuron-methyl and clodinafop-propargylis disclosed. The mass ratio of the effective compositions tribenuron methyl, mesosulfuron-methyl and clodinafop-propargyl in the weeding composition is 1-50:0.1-20:0.1-20, the effective compositions in the preparation accounts for 1%-60% by mass of the whole preparation, and the other compositions are acceptable auxiliary compositions allowed to be used in pesticides. The dosage forms of the weeding composition are missible oil, suspending agent, a wettable powder, a water-dispersable granule, an emulsion in water, a micro emulsion, a granula, a micro capsule and a water aqua. The weeding composition is capable of effectively preventing main weeds in paddy field, such as barnyard grass, Chinese sprangletop, digitaria sanguinalis, goosegrass herb and the like , and winter wheat weeds such as alopecurus aequalis Sobol, wild oats, polypogon fugax Nees ex Steud., poa pratensis, sclerochloa dura, puccinellia tenuiflora, italian ryegrass, lolium temulentum, bromus inermis, phleum paniculatum, aegilops tauschii, beckmannia syzigachne, agropyron cristatum, capsella bursa-past, descuminia sophia, malachium aquaticum and the like.
Description
technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tribenuron-methyl, mesosulfuron-methyl and clodinafop-propargyl. Background technique [0002] Tribesulfuron-methyl is a selective systemic conduction herbicide, which is mainly used to control various annual broad-leaved weeds. Well, it also has a certain control effect on Kochia scoparia, chickweed, Polygonum, and pig scorpion. The chemical name of tribenuron-methyl is 2-[N-(4-methoxy-6-methyl-1,3,5 -Triazin-2-yl)-N-methylcarbamoylsulfonyl]methyl benzoate, its chemical structural formula is. [0003] [0004] Mesulfuron-methyl is a sulfonylurea herbicide, which is mainly absorbed through the stems and leaves of plants, conducted through the phloem and xylem, and a small amount absorbed through the soil, inhibiting the activity of acetolactate synthase in sensitive plants, resulting in branched-chain aminofacic acid The sy...
