[0007] In addition, there is also a pre-emergent herbicide, which is Jing-Metolachlor. The principle of herbicide is that the weeds will kill the grass seeds in the germination stage, and it has no effect on the weeds with more than three leaves.

Embodiment 1

[0018] Example 1: 50% glufosinate-ammonium·fine-metolachlor EC

[0019]

[0020]

[0021] The active ingredients are weighed and dissolved in the solvent, and then the emulsifier is added and stirred evenly to obtain 50% glufosinate-ammonium·fine-metolachlor EC.

Embodiment 2

[0022] Example 2: 50% glufosinate-ammonium·fine-metolachlor EC

[0023]

[0024] The active ingredients are weighed and dissolved in the solvent, and then the emulsifier is added and stirred evenly to obtain 50% glufosinate·fine-metolachlor EC.

Embodiment 3

[0025] Example 3: 40% glufosinate-ammonium·fine-metolachlor EC

[0026]

[0027] The active ingredients are weighed and dissolved in the solvent, and then the emulsifier is added, and the mixture is evenly stirred to obtain 40% glufosinate-ammonium·fine-metolachlor EC.

Abstract

The invention discloses a synergistic weeding composition, which is characterized in that the synergistic weeding composition is prepared by using glufosinate and s-metolachlor as active ingredients in a compound way, and the weight ratio of the glufosinate to s-metolachlor is (1-80): (1:80). The synergistic weeding composition has the advantages that the weeds on the ground can be killed, the weed seeds which are about to germinate can also be killed at the same time and the efficacy duration is long; the weeding spectrum is wide and the synergistic weeding composition can be widely used for weeding in dry lands; and the toxicity is low, the sensitization is weak, the toxicity to crops, human and livestock is low, the weeds can be safely removed under the situation that the crops are not damaged, the weeding synergistic effect is obvious and the generation speed of pesticide resisting capacity of the weeds is slowed down.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a synergistic herbicidal composition. Background technique [0002] Crops have reduced crop yields due to weed damage. Therefore, it is necessary to apply a large amount of herbicides for weed control every year to recover crop yield losses. In recent years, the damage of weeds to crops has become more and more serious, and due to the abuse of herbicides, weeds have become more and more resistant to pesticides, resulting in lower weed control effects year by year. [0003] Currently, there are three popular herbicides: [0004] (1) Paraquat, whose chemical name is 1-1-dimethyl-4-4-bipyridine cation salt, is a fast-killing herbicide with contact and certain systemic effects. Its characteristics are: 1. It can be quickly absorbed by plant green tissues, causing it to die, and has no effect on non-green tissues; 2. It can be quickly combined with soil in the soil and purified, and it is...
