Abstract
The invention belongs to the technical field of snail control and particularly discloses an efficient snail controlling suspending agent and a preparation method thereof. The suspending agent takes metaldehyde and/or niclosamide ethanolamine as active ingredients and a natural surfactant as an emulsifying agent, and has an efficient snail controlling effect. According to the invention, the pesticide effect of the snail controlling chemical can be enhanced and the snail controlling agent can keep a high pesticide effect in a wide environment range.
Description
Technical field
The spiral shell technical field that the present invention relates to go out, more specifically, relates to the one spiral shell suspending agent and preparation method thereof that efficiently goes out.
Background technology
People use the methaldehyde and niclosamide ethanolamine salt as harmful mollusks such as the oncomelanias in Pomacea canaliculata, slug and beach or the water body in killing water field for a long time, these two kinds of medicines are all insoluble in water, the common granulation agent of the methaldehyde, cannot be used in the place that needs spraying operation; Niclosamide ethanolamine salt is made wetting powder conventionally, and pulvis dissolubility and dispersiveness are poor, causes the inequality of dispenser difficulty and liquor strength, affects sn ail control effect.In recent years also have these two kinds of medicines are made into suspending agent, as: 40% methaldehyde suspending agent, 25% niclosamide ethanolamine salt suspending agent etc., but in some environment, the drug effect of these medicaments is subject to larger inhibition.For example, the drug effect of traditional methaldehyde suspending agent is obviously subject to the impact of soil moisture, in the time that dosage is identical, sn ail control effect reduces and strengthens with earth humidity, have spiral shell region (as: ridge etc.) sn ail control effect fine at relatively drier, in moist region, (field plate, ditch, canal etc.) sn ail control effect is poor.Or the drug effect of traditional niclosamide ethanolamine salt suspending agent is subject to rich phosphorus surround inhibition, affected by phosphoric acid salt chemical fertilizer particularly serious.When in the water body in the places such as Dang Gou, canal, paddy field, phosphorus content is higher, the drug effect of niclosamide ethanolamine salt will be subject to larger inhibition, and sn ail control effect significantly declines.
Summary of the invention
The present invention is easily subject to the inhibition of environmental factor in order to overcome the drug effect of traditional molluscacide suspension, a kind of new spiral shell suspending agent that efficiently goes out is provided.It is emulsifier that the present invention adopts eco-friendly natural surfactant, taking the methaldehyde and/or niclosamide ethanolamine salt as former medicine, a kind of molluscacide efficiently of preparation, not only can strengthen the drug effect of these two kinds of snail killing agents, and make them in wider environmental field, also can keep higher drug effect.
To achieve these goals, the present invention is achieved by following scheme.
The one spiral shell suspending agent that goes out, taking the methaldehyde and/or niclosamide ethanolamine salt as main ingredient, prepares taking natural surfactant as emulsifying dispersant; Described suspending agent is made up of each component of following mass percent:

As preferred embodiment, described natural surfactant is the one or more combination in bay alkyl glucose amide, castor oil glucose amide, cocoyl glucose amide, polymer chitosan, Tea Saponin or sophorolipid.
Preferably, described defoamer is organic silicon modified by polyether alkane; Described thickener is xanthans, carboxymethyl cellulose or urea; Described antifreeze is propane diols or ethylene glycol.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts natural surfactant as emulsification, the dispersant of manufacturing the methaldehyde and/or niclosamide ethanolamine salt suspending agent, not only plays the effect of emulsion dispersion, and has four kinds of effects below:
1. pair methaldehyde and niclosamide ethanolamine salt suspending agent molluscicidal effect have obvious synergistic effect, thereby reduce the waste of medicament and the pollution to environment.
2. in the water body that is rich in phosphate, ammonium chloride etc., also can keep good sn ail control effect.A large amount of urban domestic wastewater, the a large amount of fertilizer such as phosphate-containing, ammonium chloride using in industrial wastewater, farmland that waste water, food processing and the animal product processing that particularly phosphorus-containing detergent produces produces, the phosphate that Sediments discharges, these all make in water body phosphate equal size higher, and more difficult removing, even also can only remove 0 ~ 50% phosphorus through secondary biochemical treatment, therefore in fact the phosphate equal size of water body is conventionally higher, i.e. body eutrophication.
The drug effect of traditional niclosamide ethanolamine salt suspending agent is subject to rich phosphorus surround inhibition, affected by phosphoric acid salt chemical fertilizer particularly serious.When in the water body in the places such as Dang Gou, canal, paddy field, phosphorus content is higher, the drug effect of niclosamide ethanolamine salt will be subject to larger inhibition, and sn ail control effect significantly declines.Molluscacide agent prepared by the present invention, in the water body of rich phosphorus, also can keep good sn ail control effect.
3. the insect killing effect of pair Pomacea canaliculata ovum, Oncomelania Eggs is obvious.If molluscicide can be killed Pomacea canaliculata, oncomelania in the ovum phase, be a kind of more satisfactory situation, but methaldehyde suspending agent is not obvious to the insect killing effect of Pomacea canaliculata ovum, Oncomelania Eggs, the present invention prepares molluscacide spiral shell ovum is had to good insect killing effect.
4. medicament, in the larger environment of earth humidity, also can have strong sn ail control effect.The drug effect of traditional methaldehyde suspending agent is obviously subject to the humidity effect of soil, when dosage is identical, sn ail control effect reduces and strengthens with earth humidity, there is spiral shell region (as: ridge etc.) sn ail control effect fine at relatively drier, in moist region, (field plate, ditch, canal etc.) sn ail control effect is poor, molluscacide prepared by the present invention, at the environment of high humidity, also can keep the sn ail control effect of more efficient.
