Description

A kind of azedarach plant resource nano controlled-release suspending agent
Technical field
The invention belongs to the nuisanceless fertilizer technical field, be specifically related to a kind of azedarach plant pesticide composition.
Background technology
Plant can run into various damage by disease and insect in the occurring in nature process of growth, fungus disease particularly, its kind is many, and disease is serious, and, dark fund sick etc. sick such as sick, the red gold of gold is that the disease of control occurs generally, comparatively to be difficult on many crops, bring huge loss to agricultural production, mainly occur in the parts such as tender seedling, bud, the tip of crop, when serious, blade is withered, curling, the browning look, withered.A large amount of chemical means that use are prevented and treated at present, yet domesticly for the medicament of preventing and treating powdery mildew, mainly contain the unicity of for many years medication of methyl and the particularity of chemicals, be easy in use operating personnel and ecotope be made to serious harm, and have in a large number residual, easy-clear, do not cause injury to edible people, and therefore country is own through banning use of highly toxic pesticide, greatly develop the green non-pollution vegetables, so be badly in need of developing the public nuisance-free agricultural chemicals that low toxicity is even nontoxic.Causing harm of farmland weed often causes a large amount of underproduction of crops every year.Use chemical herbicide to remain the Main Means of current weed control, but, due to a large amount of and unreasonable use chemical herbicide, caused the problems such as environmental pollution, residue of pesticide and herbicide resistance, be subject to extensive concern.Therefore, exploitation is efficient, the new herbicides of low toxicity, low-residual, becomes problem in the urgent need to address.Find bioactivator from plant, and then the environmentally friendly agricultural chemicals of development of new, be the hot fields of the outer research of Present Domestic.
China is large agricultural country, and about 400,000,000 m2 of area occur the crop diseases and pest crop smothering throughout the year, and annual the need produced and used 800,000 tons, agricultural chemicals, and agricultural chemicals has become indispensable factor in agricultural production.Being widely used of agricultural chemicals, although production development has been played to important function, also occurred pesticide resistance problem such as insect pest, disease, to the pollution of environment and in agricultural and animal products residual and accumulation problem, injure natural enemy, destroy balance of nature, cause pest resurgence problem etc.This development to novel pesticide has proposed higher requirement.Especially, since entering 21 century, along with the cry of people's uphold nature, protection of the environment, concern food security is day by day surging, harmless boilogical agricultural chemicals industry and biological control area research have obtained rare opportunity to develop.
Biotic intrusion is considered to cause the one of the main reasons of the interior ecosystem degradation of world wide and the loss of biodiversity.Instruction plant is by replacing native plants and then setting up the integrality that single species group threatens the ecosystem.Invasion mechanism and the impact of determining exotic plant are most important to predicting its spreading rate, formulation prevention and control and even ecological reconstruction (ecologicalrestoration) measure.At present, for the reasonable utilization of adventive instruction plant, report is also arranged, the Activities of Some Plants extract all possesses desinsection, antibiotic characteristic.But not yet form the commercialization pesticidal preparations, market in urgent need is a kind of is conducive to environmental protection, effectively sterilization, weeding, and can be applicable to the large nuisanceless bactericidal and herbicidal medicament of plant of producing.Will be at invasion habitat choose reasonable plantation substituted plant source pesticide by this research, thus realize its continuous and effective is controlled and technical support.
Summary of the invention
The invention provides a kind of azedarach plant resource nano controlled-release suspending agent, it is characterized in that, it comprises that the raw material of following parts by weight prepares: azedarach 10-30 part, yellow top chrysanthemum 10-20 part water 10-20 part, nano controlled-release carrier 30 as one kind-35 part;
The preparation method of described nano controlled-release carrier is:
(1) silicon hydroxyapatite, kaolin are mixed according to the mass fraction proportioning of 30-40:27-35, join in the mixed solution of 250 parts of methyl-sulfoxides (DMSO) and 50 parts of methyl alcohol, in 55 ℃, stir 50 hours, filter, and wash and remove excessive methyl-sulfoxide (DMSO) for 3 times with the hot ethanol of 60 ℃ of temperature, put into vacuum drying chamber, dry 24 hours of 60 ℃ of temperature, grinding is sieved, and obtains modified composite one time;
(2) 1 part of modified composite, 25 parts of potassium acetates and 35 parts of distilled water are mixed, in temperature 50 C, stir more than 10 hours, in 30 ℃ of temperature, first under ultrasonic electric power 350W condition, disperse 4.5 hours, and then disperse 4 hours under ultrasonic electric power 250W condition.Filter, and wash 3 times with distillation, 80 ℃ of vacuum drying 24 hours, grinding is sieved, and obtains twice-modified compound; (3) above-mentioned 1 part of twice-modified compound is disperseed to 60min at the 600W power ultrasonic, with constant temperature heating device, be heated to 90 ℃, and stir (1200r/min) 60 minutes with mechanical agitator; Obtain the nano controlled-release carrier complexes.
The preparation method of described composition is; Get azedarach 10-30 part, yellow top chrysanthemum 10-20 part according to described parts by weight, in water, soak after 2.5 hours, being warmed to 50 ℃ keeps 30 minutes, then add the cellulase of (unit of activity of 10 parts is 100U) to carry out enzymolysis, the enzyme digestion reaction temperature is 30-50 ℃, the enzyme digestion reaction time is 1.5 hours, filters and obtains Chinese herbal medicine fluid; The 75% alcohol immersion 80min that 300 parts of the described herbal liquid medicines made is added to 10 times of weight, be heated to 70 ℃ times and heat up in a steamer 45min, filters, and collects extract; Filter residue adds 70% ethanol of 5 times of weight again, be heated to 80 ℃ times and heat up in a steamer 45min, filter, collect extract, the extract of described collection is started to stir at 20 ℃, and add successively 10 parts of organosilicons, 0.5 part of dibutyl hydroxy toluene, 300 parts of soft water, 10 parts of stabilizing agents, 10 parts of wetting dispersing agents, 10 parts of antifreezing agents, 10 parts of defoamers, described nano controlled-release carrier 30 as one kind-35 part; Mixing is sized mixing, pre-dispersed by high-shear emulsion machine; The gained dispersed paste is moved into to the sand milling tank, pass into cooling water and carry out sand milling, sand milling after 4~5 μ m reach 98% or more, filters detection after debugging, the qualified finished product that is to the suspension particle diameter of material.The application of plant pesticide composition in control Cereal, fruit tree, vegetables.
Of the present inventionly can be used for broadcasting soil treatment before rear seedling, prevent and kill off the sterilization idiocratic of farmland weed and wide spectrum.Compared with prior art, it is good, environmentally safe that distinctive formula synergy formulation of the present invention has a herbicidal effect, and the weeds characteristics such as be difficult for developing immunity to drugs, have a extensive future.Formulation of the present invention is remarkable to its prevention against usual damages effect of fruit, wheat, paddy rice and vegetables.Bactericidal and herbicidal agent of the present invention relatively safely to eyes, skin nonirritant, is low toxicity through its acute toxicity of day skin evidence to people and animals, in atmosphere and soil, easily decomposes, and non-poisonous material is residual; The present invention's seed dressing is little on the impact of farmland natural enemy, contributes to keep ecotope, more friendly to environment, meets the production requirement of crop.The fertilizer efficiency time lengthening is more than 3 months, and the agricultural chemicals availability improves 18%, improves the producer's benefit.
