Description
Technical field
The present invention relates to technical field of pesticide, especially a kind of niclosamidum floating on water diffusion pulvis and its preparation side
Method.
Background technology
Japanese schistosomiasis is to have a strong impact on the infectious parasitic of our people's health.The blood reached maturity is inhaled
Worm cercaria escapes from infection oncomelania, once people and animals' Human Water Contact, cercaria invasion then easy infection snail fever, it was reported that 98% with
On schistosoma japonicum cercariae be static state on the water surface, therefore the water surface kill cercaria be control blood fluke infect key measure.
Niclosamidum is the choice drug of spiral shell of going out, and is the molluscacide that onsite application is uniquely recommended by the World Health Organization, has
Spiral shell effect of going out is good, the advantage such as low to mammal and phytotoxicity, at the same to blood fluke cercaria have kill effect, at present
Killing oncomelania and cercaria formulation are largely wettable powder, suspending agent, granule, film-spreading oil solution, are also had been reported that using floating
Granule, traditional controlling mode hangs pack mode using wettable powder, suspending agent sprays, and these controlling modes, decoction is all difficult to
The uniform spread water surface, it is bad to cercaria prevention effect, and preventing and treating is wasted time and energy, in-convenience in use, although film-spreading oil solution is compared with other
Formulation preventing and treating cercaria effect is good, using relatively convenient, but film-spreading oil solution contains the easy polluted-water of solvent, as floating particle agent
Its complex process, production cost is higher, causes to be difficult to promote the use of.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency of the prior art, there is provided one kind is easy to use, is produced into
This is low, insecticide efficiency is high, the niclosamidum floating on water of safety and environmental protection diffusion pulvis.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of niclosamidum floating on water spreads pulvis, including niclosamidum 1-10%, oily matter 2-10%, diffusant
5-20%, adsorption stuffing 1-10%, floating substance supply 100%.
Preferably, the oily matter is from white oil, soybean oil, methyl oleate, one kind of pine nut base vegetable oil.Paraffin,
One or more in alkyl fatty esters, glyceride, animal tallow, vegetable oil, bobbin oil.
Preferably, the diffusant is castor oil polyoxyethylene ether, AEO, three phenethyl phenol polyoxy second
Alkene ether, sulphosuccinates, polyoxyethylene polyoxypropylene base ether block copolymers.
Preferably, the adsorption stuffing is hydrophobic adsorption filler.
Preferably, the hydrophobic adsorption filler is hydrophobic silica, calcium stearate, magnesium stearate.
Preferably, one kind that the floating substance is selected in hollow glass bead and perlite.
A kind of preparation method of niclosamidum floating on water diffusion pulvis, diffusant is mixed with oily matter, Ran Houyou
Adsorbent is adsorbed, then is sufficiently mixed with the niclosamide active compound after air-flow crushing, floating substance by mixer.
Preferably, the niclosamidum floating on water diffusion pulvis is packed using water-soluble bag.
It is using the beneficial effect of technical scheme：
1st, it is easy to use due to being packed using water-soluble bag, it can throw in water body, this point is more advantageous than film-spreading oil solution；
2nd, efficiency high lower than floating particle agent production cost；
3rd, after water body is thrown, after the dissolving of water-soluble bag, powder can spread rapidly after meeting water to surrounding, and active ingredient is uniform
It is distributed on the water surface, can effectively kills cercaria effect；
4th, due to being free of hazardous solvent in preparation, prevention effect is good, effective ingredient consumption is small, water body will not be produced dirty
Dye, therefore, niclosamidum floating on water diffusion pulvis should be another the Labor-saving novel form for preventing and treating cercaria.

Embodiment 6
Indoor 2% niclosamidum floating on water diffusion pulvis kills schistosoma japonicum cercariae experiment
The work cercaria 20-50 bars newly escaped are added with oese to be positioned in 6 hole Bacteria Culture plates, it is flat per hole area 9.5
Square centimetre, compared with dechlorination running water, 2% niclosamidum exhibition floating on water diffusion pulvis prepared by embodiment 2 is added per hole
0.25g, 0.5g, 1g, 2g, 3g, it is repeated 4 times.Survival condition of the Microscopic observation cercaria in each concentration group decoction is being dissected, with tail
The larva of a tapeworm or the cercaria of a schistosome, which expands and throws away motionless person through fine needle stimulation, is set to death.As a result it is as follows：
Medicinal powder is applied by dosage, is spread rapidly in the water surface, 1g/9.5cm2Dosage can effectively kill tail within lower 10 minutes
The larva of a tapeworm or the cercaria of a schistosome, more than 90% controls, and dosage increasing insect killing effect is better, so life habit and chlorine nitre willow with reference to schistosoma japonicum cercariae
Amine floating on water spreads the characteristics of pulvis, the method for proposing a new preventing and treating cercaria, dosage, root is calculated according to water surface area
According to result of the test, every square metre of 3-4 milliliters (30 milligrams) can effectively controls cercaria.Niclosamidum is studied according to Cao Guoqun etc.
Water body concentration reach 0.3mg/L continuous contacts 0.5h can 100% kill cercaria, according to 1 meter of deep water body calculate every square metre with
Amount, which reaches 300 milligrams, can effectively control cercaria, after carrying out improving dosage form, greatly reduce dosage, active ingredient also only exists
In water surface, the acute toxicity to fish etc. is reduced.
