Embodiment 1

[0020] In this study, the invasive plant Solidago canadensis was used to kill apple snails in rice fields. The specific steps include:

[0021] 1. Collect the invasive plant Solidago canadensis, wash and dry in the shade in a ventilated place;

[0022] 2. Dry the shredded plant material in a constant temperature vacuum drying oven at 40°C to constant weight, crush it through a plant sample grinder, pass through a 40-mesh sieve, transfer the dry powder sample into a plastic bag and seal it, and place it in a desiccator Save it for later use.

[0023] 3. When in use, add solidago canadensis powder 9.0g / L into the water body, and all apple snails will be killed after 72 hours.

[0024] The technical method provided by the invention can effectively kill apple snails. Put apple snails of the same size and normal activities into a beaker filled with 400mL of dechlorinated tap water, add 2.4g and 3.6g of goldenrod canadensis powder respectively, add the same amount of dechlorinated...

Embodiment 2

[0026] 1. Collect solidago canadensis materials in the wild, wash them, dry them in the shade in a ventilated place, and cut them into pieces;

[0027] 2. Put the shredded Solidago canadensis in a constant temperature vacuum drying oven at 40°C and dry to constant weight, crush it through a plant sample grinder, pass through a 40-mesh sieve, transfer the dry solidago canadensis powder into a plastic bag and seal it , stored in a desiccator for later use.

[0028] 3. Adult apple snails are very harmful to rice and have strong resistance. Therefore, the toxicity of solidago canadensis dry powder to adult apple snails is selected in this example. At room temperature 25-30°C, put 80 birds / m2 in the pot 2 Adult apple snails (more than 6.5g / snail weight) are treated with treatment solutions with concentrations of 1.0g / L, 3.0g / L, 6.0g / L, 9.0g / L, 12.0g / L, and 15.0g / L, respectively, to remove Chlorinated tap water was used as a control. Observing and recording at different times, it...

Abstract

The invention relates to the technical field of the application of natural active ingredients of vegetal sources, and in particular to an application of Canada goldenrod in eradicating Amazonian snails. According to the mass concentration of 1.0g / L to 15.0g / L, Canada goldenrod powder is sprayed into water in which the distribution density of Amazonian snails does not exceeds 85 Amazonian snails / m2, and can effectively eradicate the Amazonian snails in the water. The plant material, Canada goldenrod, used in the invention is an alien invasive plant which is common in a lot of regions in China, growth is rapid, yield is extremely high, Canada goldenrod is easy to obtain, and the production cost is extremely low; the treatment method is simple and easy to implement, and obstacles in operation do not exist in the process of use; the vegetal ingredients of the natural resource cannot cause environmental pollution and produce pesticide residue and heavy metal residue, and therefore are favorable for environment protection. The product prepared by the method of the invention can effectively control and eradicate the invasive animal, Amazonian snails, a new approach is provided for the resource utilization of the alien harmful invasive plant, and turning harm into good and making waste profitable is realized.

Description

technical field [0001] The invention relates to the technical field of application of plant-derived natural ingredients, in particular to the application of solidago canadensis in killing apple snails. Background technique [0002] Pomacea canaliculata is a global aquatic mollusk invasive animal. It was introduced into China in the 1980s, and then spread rapidly to the southern provinces of my country. A female snail can reproduce 325,000 young snails in one year. It is harmful to rice and other crops in my country. The biodiversity of the waters has been seriously affected. At present, the method of controlling apple snails in my country is mainly chemically synthesized drug molluscicide, which has a wide range of applications and quick results, but there are also problems such as environmental pollution, high cost, and high toxicity to non-target organisms. WHO recommends the development of plant-derived medicines for molluscicide. Molluscicides derived from plant natural...
