Embodiment 1

[0041] Take 5kg of fresh tubers of Aracea, prepare according to the preparation process of Aracea concentrate, and obtain 5000mL of Aracea concentrate; prepare 1000mL of Streptomyces according to the preparation process of Streptomyces stock solution and take another 1000mL of azone; the rest is water. All the components are prepared according to the combination formula to prepare the combination molluscicide of Aracea and Streptomyces.

Embodiment 2

[0043] 10kg of fresh tubers of Araceae, prepared according to the preparation process of the n-butanol phase of Araceae, to obtain 2.72kg of wettable molluscicide dry powder of Aracea n-butanol extract, and dissolve the powder with an appropriate amount of water when using; separately take 1000mL of Streptomyces stock solution and Azone ; the rest is water. All the components are prepared according to the combination formula to prepare the combination molluscicide of Aracea and Streptomyces.

[0044] See Appendix 1 for application examples, Appendix 2 for the impact on fish, and Appendix 3 for Streptomyces inoculation and culture.

[0045] Annex 1: the test report of the mollusc control test (retest) of the present invention

experiment example 1

[0047] The experiment adopts soaking method. The experiment was carried out under the condition of temperature control at (20±1)°C. Take 100 live snails as a group, put every 20 into a nylon mesh bag, respectively immerse the snails of each group (3 bags or 5 bags in each group) into 1000ml of different concentrations of Araceae single component and the combination of the present invention to kill the snails Niclosamide aqueous solution and chlorine-free clear water were also set up as controls in the glass jar of the aqueous solution of niclosamide. After treatment for 1d, 2d, and 3d, a bag of oncomelania in each treatment was randomly taken out, rinsed several times with chlorine-free water, and then put into clean water to stand for 1 day, and then checked for survival: the crawlers in the open hermitage were live snails, The rest were identified as dead or alive by crushing and dissecting the thorns. The experiment was repeated 3 times, and the average value was taken as...

Abstract

The invention provides a combined molluscicide prepared by rhizoma arisaematis and streptomycete, the formula is that 1. rhizoma arisaematis concentrated liquor of 1-5% with a proportion of 1.1-1.5, 2. stock solution of streptomycete (the bacterial content is 5*10 8 per ml) of 1-1.5%, 3. azone (agricultural chemical grade, is equal to or bigger than 95%) of 0.5-1%, 4. the rest is water.The above percent represents volume ratio, after stirring the above materials, the combined molluscicide of the present invention can be formed.The other formula of the invention is wettable snail-killing powder preparation combined by rhizoma arisaematis n-butyl alcohol. The combined wettable snail-killing powder preparation consists of 1. rhizoma arisaematis n-butyl alcohol extract wettable powder preparation, 2. drying powder preparation for stock solution of streptomycete, 3. azone (agricultural chemical grade, is equal to or bigger than 95%) of 0.5-1%. The parts of 1 and 2 are mixed by a mass ratio of 1-5:1, then the mixture is added with suitable amount of water to be dissolved, and azone is added by 0.5-1% of the bulk volume content.After uniformly stirring, the combined snail-killing powder preparation is formed. The present invention has characteristics of abundant raw material resources, low cost, continuous and stable snail-killing effect, and the invention meets the requirement of environment protection.

Description

technical field [0001] The invention relates to a molluscicide for killing snails, in particular to combining a material rich in steroidal saponins and calcium oxalate needle crystals extracted from the tubers of Aracea snails with a dilution of Streptomyces purplishans for killing water and land A plant and microbial combination molluscicide for amphibian snails. Background technique [0002] Schistosomiasis is a major infectious disease that seriously endangers people's health and life safety and affects economic and social development. Oncomelania is the only host of schistosomiasis, and eradicating oncomelania is an important strategy and measure for schistosomiasis prevention and control in schistosomiasis endemic countries. At present, chemical molluscicides are still the main molluscicides in China. However, according to years of molluscicide experience, it is difficult to block the transmission of schistosomiasis by chemical molluscicide alone. For example, the cur...
