Embodiment 1

[0030] Biological Assay Example 1: Determination of the joint effect of the mixture of glufosinate-ammonium and clethodim on weeds in non-cultivated land.

[0031] In order to further understand the joint effect of the mixture of glufosinate-ammonium and clethodim on non-cultivated land weeds, the inventors conducted an indoor formula screening test on the mixture of glufosinate-ammonium and clethodim:

[0032] experiment material:

[0033] Crabgrass [Digitaria sanguinalis (L.) Scop.] (seed collection and preservation in the field).

[0034] Barnyardgrass [Eleusine indica (L.) Gaertn.] (seeds collected and preserved in the field).

[0035] Test Instruments:

[0036] Controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0037] experiment method:

[0038] First weigh a certain quality of the original drug of glufosinate-ammonium with a purity of 95%, and the original drug of clethodim with a pu...

Embodiment 2

[0048] Biological Assay Example 2: Field efficacy test of the combination of glufosinate-ammonium and clethodim in controlling weeds in non-cultivated land.

[0049] Test agents and dosage:

[0050] (1) 30% glufosinate-ammonium clethodim oil suspension concentrate (20% glufosinate-ammonium: 10% clethodim), the active ingredient dosage is 40 g / mu (1#).

[0051] (2) 25% glufosinate-ammonium · clethodim suspension concentrate (20% glufosinate-ammonium: 5% clethodim), the active ingredient dosage is 40 g / mu (2#).

[0052] Control drug and dosage:

[0053] (3) 20% glufosinate-ammonium water solution, the active ingredient dosage is 100 g / mu (3#).

[0054] (4) 240 g / L clethodim EC, the active ingredient dosage is 10 g / mu (4#).

[0055] Application period: weeds 2-3 leaf stage, mixed with water and sprayed evenly.

[0056] Table 3. Field efficacy test results of controlling weeds in direct-seeding non-arable land.

[0057]

[0058]Test results: See Table 3, as can be seen fro...

Abstract

The invention discloses a bare place weeding composition containing glufosinate ammonium and clethodim. A weight part ratio of glufosinate ammonium to clethodim is 30:1-1:10, and preferably 10:1-1:1. The weeding composition has an obviously higher control effect than single doses, reduces the use dosage of pesticides, reduces the unfavorable influences of the pesticide on the ecologic environment, is of great significance of comprehensively controlling the weed resistance, and has good economic and social benefits.

Description

technical field [0001] The invention relates to a herbicidal composition, which uses glufosinate-ammonium and clethodim 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 plant tran...
