Embodiment Construction

[0032] 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.

[0033] field efficacy test

[0034] 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

Provided is an herbicide composition containing penoxsulam, 2-methyl-4-chlorophenoxy acetic acid and pyrazosulfuron-ethyl. The mass ratio of the effective components, namely the penoxsulam to the 2-methyl-4-chlorophenoxy acetic acid to the pyrazosulfuron-ethyl in the herbicide composition is (1-50):(0.1-20):(0.1-20), the total mass of the effective components in the preparation accounts for 1%-60% of the overall preparation mass, and the balance is auxiliary components allowable and acceptable in pesticides. The dosage forms of the herbicide composition are missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water, a microemulsion, granules, microcapsules and water aqua. Main weeds in paddy fields, such as barnyard grass, leptochloa chinensis, angiospermae, eleusine indica and winter wheat weeds including alopecurus aequalis, wild oats, polypogon fugax, bluegrass, sclerochloa dura, puccinellia distans, lolium multiflorum, bearded darnel, bromegrass, phleum paniculatum, aegilops tauschii, beckmannia syzigachne, wheatgrass, shepherd's purse, descurainia sophia, chickweed and the like, can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing penoxsulam, sodium 2-methyl-4-chloride and pyrazosulfuron-methyl. Background technique [0002] Penoxsulam Penoxsulam is a post-emergence herbicide developed by Tao Nongke Company of the United States. It is a triazolopyrimidine sulfonamide herbicide and works by inhibiting acetolactate synthase (ALS). Penoxsulam is a broad-spectrum herbicide for paddy fields, which can effectively control barnyardgrass (including barnyardgrass resistant to propanil, quinclorac and acetyl-CoA carboxylase resistance), stepwort and annual sedge family weeds, and is effective against many broad-leaved weeds, such as Heterostasis marsh, carp sausage, field greens, bamboo knot flowers, and bermudagrass. The effective period is as long as 30 to 60 days, and one application can basically control the weed damage in the whole season. At the same time, it...
