Embodiment 1

[0029]The effect of sabinene on the growth of seedlings of common weeds, taking foxtail, alfalfa and retroflexus as examples:

[0030] Prepare sabinene with a purity of 95% into an emulsion suspension with a concentration of 10 μl / mL in distilled water containing 0.5% acetone by volume fraction, and then dilute the prepared emulsion suspension to 0.25 μl in sequence with distilled water containing 0.5% acetone by volume fraction / mL, 0.5μl / mL, 1μl / mL, 2μl / mL, 5μl / mL, put filter paper in a 9cm diameter Petri dish, and then add 4mL of 0.25μl / mL, 0.5μl / mL, 1μl / mL, 2μl / mL, 5μl / mL of the prepared emulsion suspension, add 10 grains of green foxtail, alfalfa and retroflexus amaranthus to each petri dish, repeat the treatment three times for each, seal it with a parafilm and place it at a temperature of 25°C After cultivating in the incubator for 5 days, measure the seedling height and root length of the seedlings;

Embodiment 2

[0034] The effect of sabinene on the growth of common weeds, such as foxtail, alfalfa, and amaranth:

[0035] Sabinene with a purity of 95% was prepared into an emulsion suspension with a concentration of 100 μl / mL in distilled water containing 0.5% acetone by volume fraction, and after shaking to form a milky white suspension, the seedlings of Setaria sativa, alfalfa and Amaranthus retroflexus were treated with Spray the healthy potted plants evenly, and observe the poisonous effect on the plants after 12 hours overnight;

[0036] Results: After 12 hours overnight, the seedlings of Setaria sativa, alfalfa and Amaranthus retroflexi all showed obvious albino and withered death phenomena, that is, the effect of the herbicide was achieved, and the specific effect was seen. image 3 .

Abstract

The invention relates to application of a natural monotepene compound sabinene in preparing a herbicide. As is shown through research tests, when the compound is applied with the low concentration of5 micrometers/milliliter, monocotyledons setaria viridis can be killed, and the compound has an obvious inhibition effect on dicotyledons amaranthus retroflexus and alfalfa. The compound contains plant volatile oil components and has fragrance, herbicidal activity and a certain pest repelling effect; the compound is prepared to different concentrations, and separately used or mixed with other pesticides for use before the seedling stage or in the seedling stage, can be naturally degraded, does not pollute the environment, can be used as a herbicide, and has huge potential commercial value.

Description

technical field [0001] The invention relates to the technical field of applying natural compounds in plant volatile oil to herbicides, in particular to the application of plant volatile oil component sabinene in herbicides. Background technique [0002] Chemical herbicides are widely used, but a variety of synthetic chemical herbicides tend to persist in nature for a long time due to the lack of corresponding microorganisms to decompose them, thus threatening the safety of soil and groundwater resources that human beings rely on for survival. However, natural ingredients extracted from nature are used as herbicides because they are easy to decompose and have no residue in nature, and they are increasingly valued. In addition, although some chemical herbicides can be decomposed in the soil, they have a single target. Due to long-term and large-scale application, weeds gradually evolve resistance, reducing or even losing their efficacy. Under such circumstances, it is particu...
