Embodiment 1

[0023] Preparation Example 1 (60% glufosinate-ammonium · 2,4-D-butyl ester suspension concentrate):

[0024] Glufosinate-ammonium 50%,

[0025] 2,4-D-Butyl Ester 10%,

[0026] Nongru 1601# 15%,

[0027] p-Oleamidoanisole Sulfonic Acid 5%,

[0028] Alkylphenol Formaldehyde Resin Ether Sulfate 4%,

[0029] Bentonite 3%,

[0030] Xanthan Gum 0.1%,

[0031] Silicone 0.4%,

[0032] Glycerol 4%,

[0033] Deionized water Make up to 100%.

[0034] The above formula is pre-crushed according to the proportion, and then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 60% glufosinate-ammonium·2,4-D-butyl ester suspension concentrate.

Embodiment 2

[0035] Preparation embodiment two: ( 60% glufosinate-ammonium · 2,4-D-butyl ester oil suspension concentrate):

[0036] Glufosinate-ammonium 50%,

[0037] 2,4-D-Butyl Ester 10%,

[0038] Vegetable oil 30%,

[0039] Bentonite 1%,

[0040] Methylated Vegetable Oil Make up to 100%.

[0041] Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix under high-speed stirring to prepare 60% glufosinate-ammonium·2,4-D-butyl ester oil suspension concentrate.

Embodiment 1

[0042] Biological assay embodiment one: Determination of the joint effect of glufosinate-ammonium mixed with 2,4-D-butyl ester on weeds in non-arable land.

[0043] In order to further understand the joint effect of the mixture of glufosinate-ammonium and 2,4-D-butyl ester on non-cultivated land weeds, the inventors conducted an indoor formula screening test on the mixture of glufosinate-ammonium and 2,4-D-butyl ester.

[0044] experiment material:

[0045] Chickweed [ Stellaria media (L.) Cyrillus] (seed collection in field preservation).

[0046] barnyard grass [ Echinochloa crusgalli (L.) Beaw Setaria] (field collection of seeds for preservation).

[0047] Test Instruments:

[0048] Controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0049] Test method: First weigh a certain mass of glufosinate-ammonium technical material with a purity of 95% and 2,4-D-butyl ester technical materia...

Abstract

The invention discloses a weeding composition containing glufosinate-ammonium and 2,4-D butylate. The mass fraction ratio of glufosinate-ammonium to 2,4-D butylate is 10:1-1:10 and the preferred mass fraction ratio is 5:1. The control effects of the weeding composition are raised obviously compared with single glufosinate-ammonium or 2,4-D butylate, the dosage of pesticides is reduced, and the adverse effects of pesticides on the ecology environment are reduced. The weeding composition has important significances on the comprehensive control of weed resistance, and has huge economic benefits and social benefits.

Description

technical field [0001] The invention relates to a herbicidal composition, which uses glufosinate-ammonium and 2,4-D-butyl ester as active ingredients and is used for preventing weeds in non-cultivated land. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Glufosinate-ammonium is a broad-spectrum contact-killing herbicide with weak systemic effect. Unlike glyphosate for root-killing, glufosinate-ammonium kills leaves first, and can be transmitted in plant xylem through pl...
