Embodiment 1

[0014] Example 1: Determination of the combined effect of glufosinate-ammonium and saflufenacil on purslane and goosegrass.

[0015] 1. Test agents: 96.5% glufosinate-ammonium technical; 97.4% saflufenacil technical.

[0016] 2. Test materials: purslane and goosegrass, which are weeds in the experimental field of Zhaoqing Zhenge Biotechnology Co., Ltd.

[0017] 3. Test drug preparation

[0018] Preparation of glufosinate-ammonium agent: Weigh 0.7772 g of 96.5% glufosinate-ammonium technical product, and dilute it to 500 mL with 1% acetone and 0.1% Tween-80 aqueous solution to obtain glufosinate-ammonium mother solution with a concentration of 1500 mg / L. In the determination, glufosinate-ammonium single agent or mixed agent was prepared with this mother liquor.

Abstract

The invention discloses a weeding composition. The weeding composition comprises a glufosinate weed killer and saflufenaci which are taken as effective ingredients and the balance of acceptable adjuvant in pesticide preparation, wherein the sum of the mass percentage of the glufosinate weed killer and the mass percentage of the saflufenaci in the composition is 10-85%, and the mass ratio of the glufosinate weed killer to the saflufenaci is (1:12)-(12:1). The weeding composition disclosed by the invention is more prominent in the control efficiency on weeds which cannot be well controlled by the single glufosinate weed killer, so that weeding spectrum range is expanded; as for lasting period, the weeding composition product disclosed by the invention can reach more than 30 days, even longer, and is more thorough and lasting when compared with a single glufosinate product and a single saflufenacil product; the weeding composition disclosed by the invention presents obvious synergetic effect within a certain proportion range; the control effect of the weeding composition is obviously improved when compared with a single agent; the use amount of the glufosinate is effectively reduced; the composition application times is reduced, however, weeding effect can be achieved; the composition application cost is reduced; environment pollution is reduced.

Description

Technical field: [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition comprising glufosinate-ammonium and saflufenacil. Background technique: [0002] Glufosinate-ammonium, CAS number: 77182-82-2, molecular formula: C 5 h 15 N 2 o 4 P, molecular weight: 198.1574 is a phosphonic acid derivative of L-glutamic acid, which causes plant death by irreversibly inhibiting glutamine synthetase and destroying related processes. Glufosinate-ammonium is a broad-spectrum contact herbicide successfully developed by Hearst (later owned by Bayer), and it is one of the largest herbicides produced in the world. It was used on the market in the 1880s, and it has strong herbicidal activity, which can effectively control almost all kinds of weeds tested, but it has no selectivity for crops. Glufosinate-ammonium and its salts are non-selective systemic herbicides with good post-emergence activity against many grass weeds. With long-term and lar...
