Description
Technical field
The present invention relates to a kind of medicine for preventing and treating Soil Pests in Tobacco Fields and preparation method thereof, more particularly to allicin preventing and treating cigarette
The method of field subterranean pest-insect.
Background technology
Guizhou is the second largest cigarette district of China, and tobacco planting area is larger, and in production season, tobacco can be subject to various pest and disease damages
Invasion, to group's phase after tobacco transplant, subterranean pest-insect is its predominantly noxa element, and wherein Agriolimax agrestis Linnaeus and black cutworm is mesh
Two class subterranean pest-insects of the most serious that cause harm in preceding Guizhou Flue-cured Tobacco production.
Agriolimax agrestis Linnaeus alias is commonly called as slug, viscous raw meat worm, non-irrigated spiral shell, software snail without slug spiral shell, and the torrid zone, subtropical zone, temperate zone are equal
It is distributed, Agriolimax agrestis Linnaeus like the environment of dark, moist, many humus, its movable optimum temperature is 15~25 DEG C, is common cigarette
Field subterranean pest-insect.
Black cutworm larvae is commonly called as grub, cutworm, cuts worm, cutworm, agrotis, and its Suitable ranges is 18~26
DEG C, like wetland environment, it is one of important subterranean pest-insect of tobacco.
Agriolimax agrestis Linnaeus and black cutworm are mainly causes harm seedbed and transplants the tobacco seedlings for extremely rolling into a ball a phase.Current Guizhou Tobacco is most common
Transplanting method be that well cellar for storing things formula is transplanted, the transplanting method can provide suitable humiture for seedling, the early growth and quick tiller of promotion tobacco；
But also often caused after transplanting for the growth of subterranean pest-insect provides best temperature and humidity conditions and illumination condition simultaneously
Agriolimax agrestis Linnaeus and the big generation of black cutworm, serious harm tobacco growing, turned at present cause harm Tobacco Leaves in Guizhou growth it is main because
One of element.
The medicine for preventing and treating also slug commonly used in production at present is Metaldehyde class medicine, and the medicine for preventing and treating cutworm is main
It is the insecticides such as decis, although effect is significant, but generally requires multiple dispenser, and medicine can only just rise after contacting pests
Effect, in the pest damage heavier time, insecticidal effect has a certain limitation, and there are residues of pesticides after being used for multiple times.
The content of the invention
The technical problem to be solved in the present invention is：A kind of medicament easy to use, efficient, low-residual is provided and its skill is used
Art, has solved the deficiencies in the prior art.
The technical scheme is that：A kind of medicine for preventing and treating Soil Pests in Tobacco Fields, the medicine is that concentration is 1 percent
To millesimal allicin solution or allicin spansule.
A kind of preparation method of the medicine for preventing and treating Soil Pests in Tobacco Fields, comprises the steps of：
（1）In allicin slow-releasing pill prepared by allicin oil phase materials：
Configuration allicin solution A 1：Allicin is dissolved in dimethylbenzene, configuration quality percent concentration is 0.1-99.9%
Allicin xylene solution A1；
Prepare the maize cob meal material A 2 of absorption allicin：By solution A 1 and 60-200 mesh maize cob meal 12- in mass ratio
1:1 is well mixed；
(2) prepared by allicin slow-releasing pill reclaimed water phase materials：Configuration aqueous phase solution B1：By carboxymethyl cellulose, sodium alginate,
Xanthans and polyethylene glycol are dissolved in the water, and carboxymethylcellulose calcium is obtained and sodium alginate mass percent concentration is respectively 0.2-
10%, xanthans mass percent concentration 0.1-1%, the aqueous-phase material material solution B 1 of polyethylene glycol mass percent concentration 0.1-1%；
(3) curing molding of allicin slow-releasing pill：
It is prepared by allicin oil water mixed solution：The maize cob meal material A 2 and aqueous-phase material material solution B 1 of allicin will be adsorbed with
In mass ratio 1:1.5-100 is well mixed, and forms allicin oil water mixed solution C1；
Allicin slow-releasing pill extrudes curing molding：C1 is expressed into solidify liquid, you can curing molding, obtains allicin
Slow-releasing pill.
The solidification formula of liquid is 0.1-0.5% acetic acid and 1-4% calcium chloride mixed solutions.
Beneficial effects of the present invention：Allicin（Allicin）It is to be extracted from the bulb of Liliaceae allium garlic
One class organosulfur compound, main component is garlicin, diallyl disulfide, methacrylic trithio, methallyl
The material such as the sulphur of base two and allyl sulfide, there is strong garlic smell, and plays the role of sterilized and desinsection, has to slug and tags strongly
Effect.Slug and cutworm are the insects more sensitive to smell, are sprayed after allicin is diluted in well cellar for storing things, and its is strong
Garlic smell can be such that slug and cutworm flees from rapidly, and well cellar for storing things depth is general at 20 centimeters or so, well cellar for storing things bottom temp after transplanting
Typically at 20 degree or so, in relatively closed environment, allicin is relatively slow in 20 degree or so degradeds, still has compared with air within 15 days or so
Taste, its alleviation formulation is then degraded more slowly, can be maintained more than 30 days, can meet Production requirement.
In the case where emulsifying agent is not used, realize prepared by water-in-oil type allicin slow-releasing pill.Using maize cob meal
Be fixed to liquid allicin liquid in maize cob meal by porous strong absorption property, then by solid content maize cob meal in water phase
Good dispersion, realize that allicin is dispersed in aqueous phase system.Then by curing molding, dispersion is consolidated
Change, form the oil/water mixed stability dispersion comprising allicin, and obtain allicin slow-releasing pill.
