Problems solved by technology

[0003] Studies have found that Mikania micrantha extract can cause damage to the main organs and tissues of apple snails
However, causing damage does not mean that it can be completely killed. There are still no reports on the form of Mikania micrantha that can kill apple snails and the concentration that needs to be achieved. Therefore, there are still great difficulties in practical application of using Mikania micrantha to kill apple snails.

Embodiment 1

[0019] This embodiment provides a method for using Mikania micrantha to kill snails, and the specific steps include:

[0020] (1) Collect the entire invasive plant Mikania micrantha, wash the plant materials, and dry in the shade in a ventilated place;

[0021] (2) The cut plant materials are dried in a constant temperature blast drying oven at 60°C for 24 hours, crushed by a plant sample crusher, passed through a 40-mesh sieve, and the dry powder sample is put into a plastic bag, sealed, and dried. Keep in the device for future use;

[0022] (3) When using, add 5 g / L of Mikania micrantha dry powder to a distribution density of about 60 snails / m 2 In the water bodies of rice fields, the snails were completely killed after 3 days.

Embodiment 2

[0024] In this embodiment, Mikania micrantha is used to kill snails, the specific steps include:

[0025] (1) Collect the entire invasive plant Mikania micrantha, wash the plant materials, and dry in the shade in a ventilated place;

[0026] (2) The cut plant materials are dried in a constant temperature blast drying oven at 60°C for 24 hours, crushed by a plant sample crusher, passed through a 40-mesh sieve, and the dry powder sample is put into a plastic bag, sealed, and dried. Keep in the device for future use;

[0027] (3) When using, add Mikania micrantha dry powder at 0, 0.005g / L, 2g / L, 5g / L, 10g / L to the distribution density of about 70 snails / m 2 Among the farmland ditches, the mortality rate of the snails in the 2g / L, 5g / L, and 10g / L treatment groups reached 91%, 100% and 100% respectively after 3 days, and all the three treatments could completely kill the snails after 5 days; and 0 The mortality rate of snails in the two treatment groups of, 0.005g / L was 0 regardless of w...

Abstract

The invention belongs to the technical field of utilization of ampullariidae killing plant resources and particularly relates to a method for killing ampullariidae by using mikania micrantha. The method for killing the ampullariidae by using the mikania micrantha comprises the following steps: throwing mikania micrantha powder into water containing the ampullariidae for directly killing the ampullariidae, wherein the using amount of the mikania micrantha powder is 005-15 g / L. The method for killing the ampullariidae by using the mikania micrantha has the advantage that the plant material mikania micrantha is a common invasive plant in southern China, is easy to obtain and can effectively kill the ampullariidae at a certain using amount.

Description

technical field [0001] The invention belongs to the technical field of utilization of snail-killing plant resources, and in particular relates to a method for killing apple snails by using Mikania micrantha. Background technique [0002] Apple snail is a dangerous and harmful invasive organism that has attracted much attention in the world in recent years. It has strong stress resistance, miscellaneous feeding habits, large food intake, astonishing fecundity and extremely fast growth rate. It has great impact on rice production and rice field biodiversity in southern my country The danger is serious. At present, the agents used to control apple snails in my country are basically chemical agents. In addition to easily polluting the environment, there are also problems of high price and high toxicity to non-target organisms. The development and utilization of molluscicidal plant resources is an important way to biologically kill molluscs. The use of botanical pesticides to co...
