Problems solved by technology

In terms of using plant preparations to kill oncomelania, the Hubei Institute of Schistosomiasis Prevention and Control once used turmeric saponin, which is extracted from the plant turmeric, to kill oncomelania. , harmless, but its price is too expensive, it takes about 2000 yuan / mu to kill oncomelania, so it is not easy to promote
So far, there is no commercial application of an economical and cheap plant molluscicide at home and abroad.

Embodiment 1

[0018] Experiment on Oncomelania snails soaked in oil-tea camellia seed cake soaking liquid indoor

[0019] This test adopts dip killing method, and the temperature is controlled at 25°C±1°C. Freshly dried Camellia oleifera seed cake (purchased from Qichun County, Hubei Province) after oil extraction in the same year was taken, and the Camellia oleifera seed cake was crushed into 20 mesh camellia seed cake powder with a pulverizer, which was used as raw material for indoor oncomelania dipping and killing. In each treatment of this embodiment, the usage amount of camellia oleifera seed cake is calculated based on the amount of camellia oleifera seed biscuit powder applied per cubic meter. Considering that the present embodiment is carried out in a plastic basin, the embodiment will simulate the wet state of the outdoor environment. First, according to the concentration requirements of each treatment, the dry camellia seed cake powder is weighed according to 1 kg of camellia see...

Embodiment 2

[0026] Oncomelania snail-killing test of camellia seed cake + ammonium bicarbonate dipping and single ammonium bicarbonate dipping

[0027] In order to verify the killing effect of the application of camellia seed cake powder and ammonium bicarbonate, a commonly used fertilizer for rice, on snails in paddy fields, the applicant conducted an indoor snail killing test with camellia seed cake + ammonium bicarbonate dipping and ammonium bicarbonate alone. The experimental design and material processing method are the same as in Example 1.

[0028] The dosage of single ammonium bicarbonate is 75g / m 3 , times, 125g / m 3 , times, 175g / m 3 , times, 225g / m 3 , times, 275g / m 3 1, 2, 5 treatments, and two controls of clear water and commonly used drug niclosalate, and the application rate of oilseed cake powder was uniformly set at 50g / m 3 , time, the treatment design of camellia oleifera seed cake+ammonium bicarbonate is shown in Table 2, and the application rate of the chemical age...

Embodiment 3

[0034] Experiment of spraying oncomelania seed cake outdoors on snails

[0035] Test materials: the freshly dried Camellia oleifera seed cake is pulverized to 20 mesh with a pulverizer, the niclosalate is the same as in Example 1, and the source of ammonium bicarbonate is the same as in Example 2. The experiment was designed according to the treatment concentrations in Table 4. The identification method of Oncomelania dead or alive is the same as in Example 1.

[0036] Test materials and methods: The preparation method of oil tea seed cake soaking liquid is the same as that in Example 1. The test site is the oncomelania breeding beach within the scope of Xintan Town, Honghu City, Hubei Province, and the test beach is divided into 7 treatment plots, each with an area of ​​1m 2 , The sections are separated by ditches with a depth of 10cm and a width of 10cm. 25g / m2 for test area 1-3 2 Camellia seed cake spraying, 75g / m2 for zone 4-6 2 Camellia seed cake spraying, 120g / m2 fo...

Abstract

A method for controlling the oncomelania by using the tea-oil tree's seed cake includes such steps as pulverizing by 20 meshes, and proportionally applying directly or after immersed for 4-10 hr.

Description

technical field [0001] The invention relates to a method for killing oncomelania snails by using camellia oleifera cake, and belongs to the technical field of comprehensive prevention and control of agricultural harmful organisms. Background technique [0002] Oncomelania snail is the only intermediate host of Schistosomiasis japonicum. Elimination of snails is the key to control the spread of schistosomiasis. However, the traditional molluscicide methods have different defects, and the cost of molluscicide by physical engineering is huge; by chemical methods, sodium pentachlorophenate and niclosalate are usually used to kill molluscs (Qian Wanhong et al. Advances in research on plant molluscicides, Schistosoma chinensis Disease Control Journal, 2002, 14 (1): 67-69), a large amount of data shows that it is all poisonous to people, livestock, and fish, and it is easy to destroy the ecological environment, causing environmental pollution, a...
