Problems solved by technology

[0015] In view of the fact that Xanthin is reported to have anti-tumor and microbial growth inhibitory activities at home and abroad, but the growth inhibitory effect (phytotoxicity) of Xanthin on other plants has not been reported at home and abroad, the present invention aims at Provide a non-toxic and non-polluting natural herbicide derived from plants. By extracting cockleburin from Italian cocklebur as a herbicide, even at a low concentration of 10μg / ml, it is difficult for four common general herbicides The seedling growth of the eradicated wild weeds Lettuce, Bluegrass, Camelina and Amaranth can be significantly inhibited. As a herbicide, it can be formulated into different concentrations and used alone or in combination with other pesticides at the pre-emergence or seedling stage. It is widely used in In the development of various herbicides, it has great potential commercial application value

Embodiment 1

[0031] Example 1: Extracting Xanthin from Xanthium cockleburi as a herbicide

[0032] The purified Xanthin with a purity of 98% was prepared with acetone to a concentration of 1000 μg / ml, and then diluted to 10 μg / ml, 50 μg / ml, 250 μg / ml, and 1000 μg / ml. Place the filter paper in a petri dish with a diameter of 9 cm, and then add 3 ml of xanthine solution with a concentration of 10 μg / ml, 50 μg / ml, 250 μg / ml, and 1000 μg / ml respectively. After the acetone is completely volatilized, add 3ml of distilled water to each petri dish, and add 10 seeds of poison lettuce, bluegrass, camel grass and retroflexus amaranthus to each petri dish, and each treatment is repeated three times; After sealing the film, place it in a 25°C incubator and culture it in the dark for 5 days, then measure the seedling height and root length of the seedlings.

[0033] Statistical method of data: Firstly, one-way variance was used to detect whether the difference between the data of each group was signifi...

Embodiment 2

[0035] Example 2: Extracting Xanthin from Xanthium fruticosa as a herbicide and comparison of the action intensity of the commercial herbicide promethazine

[0036] METHODS: Using the above method, the commercial herbicide promethazin was also formulated into a concentration gradient of 10, 50, 250, and 1000 μg / ml, and the seeds of lettuce, bluegrass, camelus and retroflexus were cultivated at 25°C, and the seeds were grown at 25°C. After 5 days, root length and seedling height were measured for statistical analysis.

[0037] Results: Under the action of low concentration of 10μg / ml, except bluegrass, the growth of other tested plant seedlings were significantly affected, and the effect of concentration gradient appeared. When the concentration reached 50 μg / ml, the root lengths of lettuce, bluegrass, camel and amaranthus were 46%, 72%, 13% and 27% of the control; The root lengths of , bluegrass, camel and amaranthus were 41%, 66%, 6% and 17% of the control in turn. When the...

Abstract

The invention discloses herbicide application of xanthatin extracted from Xanthium italicum. Xanthatin extracted from Xanthium italicum is used at low concentration (10mug / ml) for remarkably inhibiting growth of common weed seedlings such as monocot and dicot weeds (Lactuca virosa, bluegrass, Peganum harmala and Amaranthus retroflexus); the Xanthatin extracted from Xanthium italicum is a natural plant ingredient, can be easily degraded in nature, is non-poisonous and non-pollution, can be prepared to be at different concentrations when being used as the herbicide, can be individually used or used with the combination of other pesticides before preemergence or in a seedling stage, can be widely applied to development of various herbicides and has wide application value; the chemical structural formula of the Xanthatin extracted from Xanthium italicum is as shown in a figure.

Description

field of invention [0001] The present invention relates to the technical field of extracting compounds from plants and applying them to herbicides. Specifically, the present invention relates to the technical field of extracting Xanthin from Xanthium fruticosa and using them as herbicides. Background technique [0002] Chemical herbicides are widely used in agriculture, forestry and animal husbandry, but they often cause pollution to the natural environment. 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, due to long-term an...
