Description
Affiliated technical field
The invention belongs to the chemical pesticide field, the application of particularly a kind of microcapsules slow release method in the agent of agricultural-chemical suspension kind clothing.
Background technology
The agent of kind clothing belongs to a kind of novel agrochemical on the domestic and international market; it is that raw material is composite forms by insecticide, bactericide, compound fertilizer, trace element, film forming agent etc.; the medicine, the fertile joint product that adopt advanced technologies to process; with kind of a clothing agent crop seeds is carried out dressing; all be protected inside and outside can making seed, not only can prevent and cure diseases, defending insect and killing, but also can promote plant growth; improve output, in extensive use all over the world.
At present, planting clothing agent and breeding packaging technique is the important means of agricultural sustainable development, is the important component part of " seed engineering " project of China's emphasis enforcement.But,, be that the Main Ingredients and Appearance person is in the majority with high-toxic pesticide carbofuran, the different sulphur phosphorus of methyl, thimet etc. from the kind of present kind of clothing agent registration.The many institutes of the toxicity of chemical pesticide pay close attention to, the agent of kind clothing more should consider operate and application process in to the safety and the residue problem of people, animal.For example just limit the use of the agent of high seed culture of viruses clothing, because the residue problem of high seed culture of viruses clothing agent has limited the outlet of peanut in peanut producing region, Shandong.Develop, develop, manage green nuisance free pesticide, become the new strategy that agricultural chemicals enterprise realizes sustainable development.
Summary of the invention
Technical problem to be solved by this invention is to provide the application technology of a kind of controlled release formulation of capsule in suspension seed-coating agent, thus the kind clothing agent that forms of scheme have efficiently, low toxicity, characteristics pollution-free, with low cost.
Technical solution of the present invention can realize according to following mode:
The application of controlled release formulation of capsule in suspension seed-coating agent is characterized in: carry out successively as follows:
(a) bulk drug is made controlled release formulation of capsule, particle diameter is at 5～10 microns;
(b) with solid material bactericide and part of auxiliary, little fertilizer and after suitable quantity of water is mixed, grind by sand mill, particle diameter reaches 5～15 microns;
(c) the abundant mixing of controlled release formulation of capsule of material that the b step is formed and the formation of a step adds film forming agent, dispersant, antifreezing agent, emulsifier, dispersant again, and mixing is made suspension seed-coating agent.
The above-mentioned raw materials medicine can be phoxim.
Formed kind of clothing agent of the present invention has efficiently, low toxicity, pollution-free, meets country's requirement to agricultural chemicals aspect agricultural product.Hot suspension seed-coating agent control peanut soil pest, stem rot drug effect result more than 16%

Embodiment
Embodiment 1:
The present invention makes controlled release formulation of capsule earlier with the insecticide phoxim in the suspension seed-coating agent, and then adding of germicide and other auxiliary agent are made kind of a clothing agent.After adopting the microcapsules slow release method, phoxim is wrapped by polymeric membrane, forms the invisible bead of the several microns of diameter.In storage process, the film formed capsule skin of macromolecule is isolated phoxim and water, greatly reduce its resolution ratio, make its heat storage resolution ratio drop to 3～5% by 40～50%, simultaneously after using, polymeric membrane controlled phoxim progressively discharges, and prolongs the duration of control soil insect to the infringement of seed.
The production stage of hot soybean peanut suspension seed-coating agent is followed successively by more than 16%:
(a) the phoxim bulk drug is made controlled release formulation of capsule, the capsule skin is macromolecular material (PADI and TDI), and phoxim is wrapped in wherein, shears by stirring, and the microcapsules particle diameter is at 5～10 microns; Its concrete procedure of processing is: 1) be mixed: with phoxim bulk drug, high score ascus leather material (PADI and TDI), emulsifier 0203B, solvent benzol after accurate metering, drop into blending tank successively, phoxim accounts for 25% (weight percentage) of total inventory, emulsifier 0203B: PADI: TDI: the ingredient proportion of solvent benzol is 1: 3: 3: 2 (weight portions), stirred 10 minutes, 15 ℃～20 ℃ of temperature, discharging is used for next procedure; 2) polymerization: with water and pulp powder by the ingredient proportion of 50: 1 (weight portion) after accurately measuring, drop into successively in the polymerization tank and fully stirred 10 minutes, and then drop into the 1st road and be mixed after mixed ingredients in the operation stirs, add quantitative liquid caustic soda (concentration is 25%NaOH) again, continue to stir 5 minutes, regulate the pH value to 9-10, can squeeze in the curing jar and be cured 20 ℃～25 ℃ of temperature requirements; 3) solidify: when material stirs about 50 minutes in solidifying jar, add quantitative ammonium chloride and water again, ingredient proportion 1: 1 (weight portion), 25 ℃ of temperature requirements continue to stir 40 minutes again.Treat that the pH value reduced at 7 o'clock, the Phoxim microcapsule sustained release agent is made, and stores standby.
(b) solid material fungicide carbendazim, auxiliary agent (dispersing agent MF), little fertilizer and suitable quantity of water are mixed evenly by the emulsify at a high speed clipper, grind by sand mill, particle diameter reaches 5～15 microns;
(c) material that (b) step is formed and (a) the abundant mixing of controlled release formulation of capsule of step formation, again with the film forming agent polyvinyl alcohol, emulsifier 0203B, antifreeze glycol, dispersant OX-656 were by 1: 1: 4: 2 (weight portions) add, and mixing is made hot soybean peanut suspension seed-coating agent more than 16%.
