Abstract
The invention discloses a pesticide for preventing and controlling soil insects in the tobacco field. The pesticide is characterized in that the pesticide is an allicin solution or allicin sustained release capsules with the effective concentration of 0.1-1%; allicin has strong garlic smell, has the functions of sterilizing and killing insects, and has strong contact killing action on slugs; slugs and agrotis ypsilon are injurious insects which are sensitive to smells, and after allicin is diluted and is sprayed in a well cellar, slugs and agrotis ypsilon can escape quickly when smelling strong allicin smell; the well cellar is about 20cm in depth, the temperature of the bottom of the well cellar is about 20 DEG C after transplanting, allicin is degraded slowly at about 20 DEG C in a relatively closed environment, and still has heavy smell after about 15 days, the sustained release dosage form of the allicin is degraded slowly, the pesticide effect can keep for more than 30 days, the production requirement can be met, and the pesticide is a high-efficiency, low-toxicity, no-residue and environment-friendly pesticide agent.
Description
Technical field
The present invention relates to a kind of medicine preventing and treating Soil Pests in Tobacco Fields and preparation method thereof, particularly the method for allicin control Soil Pests in Tobacco Fields.
Background technology
Guizhou is opium district of China second, tobacco planting area is larger, producing season, tobacco can be subject to the invasion of various damage by disease and insect, to group's phase after tobacco transplant, soil insect is that it is mainly noxa element, and wherein Agriolimax agrestis Linnaeus and black cutworm are two the most serious class soil insects of causing harm during current Guizhou Flue-cured Tobacco is produced.
Agriolimax agrestis Linnaeus another name is without slug spiral shell, be commonly called as slug, sticky raw meat worm, non-irrigated spiral shell, software snail, all there is distribution in the torrid zone, subtropics, temperate zone, and Agriolimax agrestis Linnaeus happiness is dark, moist, the environment of many humus, the optimum temperature of its activity is 15 ~ 25 DEG C, is common Soil Pests in Tobacco Fields.
Black cutworm larvae is commonly called as grub, cutworm, cuts worm, root eating insect, agrotis, and its Suitable ranges is 18 ~ 26 DEG C, likes wetland environment, is one of important soil insect of tobacco.
Agriolimax agrestis Linnaeus and black cutworm mainly cause harm seedbed and transplant to group a phase cigarette seedling.The modal transplanting method of current Guizhou Tobacco is that well cellar for storing things formula is transplanted, and this transplanting method can be the temp. and humidity that seedling provides suitable, promotes the early growth and quick tiller of tobacco; But simultaneously also for the growth of soil insect provides best temperature and humidity conditions and illumination condition, the large generation of Agriolimax agrestis Linnaeus and black cutworm is often caused after transplanting, serious harm tobacco growing, has become one of principal element of Tobacco Leaves in Guizhou growth of causing harm at present.
The medicine of control conventional in current production also slug is metaldehyde class medicine, if insecticides such as the drug main decises of control cutworm, although Be very effective, but often need repeatedly dispenser, and medicine can only just onset after contacting pests, in the time that pest damage is heavier, insecticidal effect has certain limitation, and there is the problem of residue of pesticide after repeatedly using.
Summary of the invention
The technical problem to be solved in the present invention is: the medicament and the operation technique thereof that provide a kind of easy to use, efficient, low-residual, solve the deficiencies in the prior art.
Technical scheme of the present invention is: a kind of medicine preventing and treating Soil Pests in Tobacco Fields, and this medicine is concentration is that one of percentage is to millesimal allicin solution or allicin spansule.
Prevent and treat a preparation method for the medicine of Soil Pests in Tobacco Fields, comprise following steps:
(1) allicin oil phase materials preparation in allicin slow-releasing pill:
Configuration allicin solution A 1: be dissolved in by allicin in dimethylbenzene, configuration quality percent concentration is the allicin xylene solution A1 of 0.1-99.9%;
The maize cob meal material A 2 of preparation absorption allicin: by solution A 1 and 60-200 order maize cob meal in mass ratio 12-1:1 mix;
(2) aqueous phase material preparation in allicin slow-releasing pill: configuration aqueous phase solution B1: carboxymethyl cellulose, sodium alginate, xanthans and polyethylene glycol are dissolved in the water, obtained carboxymethyl cellulose and sodium alginate mass percent concentration are respectively 0.2-10%, the aqueous phase material solution B 1 of xanthans mass percent concentration 0.1-1%, polyethylene glycol mass percent concentration 0.1-1%;
(3) curing molding of allicin slow-releasing pill:
Prepared by allicin oil water mixed solution: by the maize cob meal material A 2 being adsorbed with allicin and aqueous phase material solution B 1 in mass ratio 1:1.5-100 mix, formation allicin oil water mixed solution C1;
Allicin slow-releasing pill extrudes curing molding: be expressed into by C1 in consolidation liquid, get final product curing molding, obtains allicin slow-releasing pill.
Described consolidation liquid formula is 0.1-0.5% acetic acid and 1-4% calcium chloride mixed solution.
Beneficial effect of the present invention: allicin (Allicin) is the class organosulfur compound extracted from the bulb of Liliaceae allium garlic, main component is the materials such as garlicin, diallyl disulfide, methacrylic trithio, methacrylic two sulphur and allyl sulfide, there is strong garlic smell, and have the effect of sterilization and desinsection, there is strong action of contace poison to slug.Slug and cutworm are all insects comparatively responsive to smell, spray after allicin is diluted in well cellar for storing things, its strong garlic smell can make slug and cutworm flee from rapidly, and the well cellar for storing things degree of depth is generally at about 20 centimeters, and after transplanting, well cellar for storing things bottom temp is generally at about 20 degree, in relatively airtight environment, allicin is comparatively slow about 20 degree degradeds, within about 15 days, still has larger smell, and its alleviation formulation is then degraded slower, more than 30 days can be maintained, can Production requirement be met.
When not using emulsifier, realize the preparation of water-in-oil type allicin slow-releasing pill.Utilize the strong absorption property of the porous of maize cob meal to be fixed in maize cob meal by liquid allicin liquid, then by the good dispersion of solid content maize cob meal in aqueous phase, realize dispersed in aqueous phase system of allicin.Subsequently by curing molding, dispersion is solidified, form the oil/water mixed stability dispersion comprising allicin, and obtain allicin slow-releasing pill.
