As compared with general seed-coating agent and seed-dressing agent, said invented product possesses the advantages of rapid drying speed, uniform and firm coated film, low toxicity, safety and obvious effect for regulating and promoting plant growth.
Description
The present invention relates to a kind of usefulness and contain various chemically reactive substances, and the suspension with filming function is handled the seed coating medicine and the manufacture method thereof of crop seeds.
The seed of crops is handled with chemical pesticide (insecticide or bactericide) and is had many good qualities, and the one, help keeping a full stand of seedings; The 2nd, help volume increase; The 3rd, help preventing the propagation of the entrained damage by disease and insect of seed.In general, in order to prevent and treat the crops seedling stage diseases and pests, the peasant of China often at the sowing scene directly with chemical pesticide to the seed processing of dressing seed.This way exists many shortcomings, and the one, most seed dressings belong to hypertoxic type, as 3911, furans pellet etc., self-protection poor consciousness when the peasant dresses seed causes pesticide poisoning easily, also is easy to cause the death of nontarget organism (as birds); The 2nd, the surface of the seed of on-the-spot directly seed dressing is wetter, is unfavorable for mechanical planting; The 3rd, directly the agricultural chemicals on top layer, seed dressing back easily comes off in the sowing process, makes the deleterious of kill harmful biology; The 4th, because the purpose of seed dressing is more single, seed dressing or desinsection, or sterilization, being difficult to provides plant growth regulator and growth institute essential trace element to seed simultaneously.Make the shortcoming that the surface of the seed is moistening and the longevity of residure is short in order to overcome direct seed dressing, China has the minority manufacturer production to have the coating agent for seed of filming function at present.But the product that they produce also has following shortcoming, the one, and kind of clothing agent is many to be purpose with simple desinsection or sterilization, comprehensive function is relatively poor; The 2nd, by ability, it is even to be difficult for bag jail bag to the bag of seed for the film forming agent of selecting for use; The 3rd, slightly influential to the sprouting of seed, have and cause late-maturing possibility; The 4th, be insecticide with 3911 and furans pellet of severe toxicity, product toxicity is very high, and since agricultural go up and use these agricultural chemicals throughout the year, undesirable to the preventive effect of insect; The 5th, owing to added film forming agent, the on-the-spot seed that uses is air-dry slow, and this is especially outstanding in the northern area shortcoming.
In view of existing seed dressing and the seed coating medicine weak point technically of handling seed, the object of the present invention is to provide the rapid draing of a kind of energy, the coating ability is strong, efficient kill harmful biology, and the low toxicity type coating agent for seed of required little fertilizer of seed and coordinate plant growth can be provided.
The objective of the invention is to realize by following measure: added the chemical pesticide of 10-50% in the coating agent for seed of being invented, this agricultural chemicals can be an insecticide, can be bactericide, also can be the compound of the two.According to the use present situation of China's agricultural chemicals in the last few years, we have selected for use Imidacloprid and cyfluthrin to make insecticide in the coating agent for seed.Imidacloprid is a kind of interior absorption heterocycle worm agent of high-efficiency broad spectrum, and its effect characteristics are to suppress the what acyl acetylcholinergic receptor of insect, thereby disturb the pest movements nervous system, and it is malfunctioning that chemical signal is transmitted.Because this insecticide is different fully with the conventional pesticides mechanism of action, so no cross resistance problem.This medicine toxicity is low, and to the natural enemy of insect, useful insect influence is little, environmentally safe.Absorption is very strong in it, and sucking mouthpart insect (as aphid) is had extraordinary killing effect, and the longevity of residure is long, is particularly suitable for doing kind of a clothing agent.In order to enlarge insecticidal spectrum and to improve insecticide efficiency, also add another functional and relatively safer insecticide cyfluthrin of tagging, it can prevent and treat soil insect effectively.These two kinds of chemical pesticides are worked in coordination, and can prevent and treat the various agricultural insect, and consumption are few, and toxicity is low, and is safe in utilization.As being main purpose with the sterilization, chemical pesticide can be the 10-50% bactericide in the prescription, and we have selected the mixture of carbendazim and captan for use.Carbendazim is a systemic fungicide, can enter kind of skin and embryo behind dressing, kills the surface of the seed and hides the germ of seed inside; In addition, it enters young shoot and young root behind seed germination, thereby the protection seedling avoids infecting of soil-borne disease bacterium.Carbendazim can be prevented and treated fusarium wilt effectively, root rot, anthracnose etc.Captan is the broad spectrum protection bactericide, and the disease of various plants is had very high control efficiency, can be used as the root rot of plurality of cereals and vegetable crop, damping off, eqpidemic disease, the control of downy mildew and anthracnose.The two mixes use, than using better effects if separately.If not only think desinsection but also think sterilization, can add the insecticide of 10-25% and the bactericide of 10-25% simultaneously in the prescription.
In order to improve the sprouting ability of seed, increase the output of crops, in the seed coating medicine of being invented, add a small amount of plant growth regulator, as add the 0.001-0.003% brassin lactones, can promote seed germination, strengthen the seedling growing way, improve the crop disease-resistant ability and shorten crop growth period (results in advance).Most important want be, brassin lactones can improve the bactericidal effect of bactericide significantly, it has played the bactericide synergist at this.For the purpose of increasing production, also in prescription, added 2-10% trace copper and iron MnZn boron molybdenum, the material of adding is copper sulphate, ferrous sulfate, manganese sulphate, zinc sulphate, boric acid and ammonium molybdate.
The film forming agent that can adopt has multiple, and water-fast resin emulsion is arranged, as polyvinyl acetate emulsion, and polyacrylic acid emulsion, the polyacrylonitrile emulsion of partial hydrolysis, polyvinyl chloride emulsion etc.; The water-soluble cellulose family plastics of energy are also arranged, polyvinylpyrrolidone, natural materials chitosan etc.Ability from film forming, the pliability of coating and wearability, the difficulty or ease of seed coating medicine manufacture process and the aspects such as rate of release of coating are considered comprehensively, adopt cellulosic plastics such as methylcellulose, hydroxyethylcellulose, the methylol methylcellulose, HEMC, hydroxypropyl methylcelluloses etc. are relatively good.These instant water are dissolved in the cellulose family film forming agent of organic solvent again, as hydroxypropyl methylcellulose, have easy bag jail bag evenly, the intensity height of coating, and scratch-resistant performance is strong, with dyestuff, advantage such as the compatibility of agricultural chemicals is good, and the ability of anti-metal ion is strong.Although this class material has many common properties,, be best with the hydroxypropyl methylcellulose as film forming agent; This be because it in dissolubility, dispersiveness, stability, equalization, the adhesiveness aspect all is better than other cellulose ethers.In the aqueous solution of hydroxypropyl methylcellulose, add a small amount of other water-soluble cellulose ether, can increase the viscosity of solution effectively, improve its dispersion and suspendability.Account in the ratio of total prescription 2-8% at film forming agent, the optimal proportion of hydroxypropyl methylcellulose and other water-soluble cellulose ether is 4-8: 1.In order to increase the pliability of coating, in prescription, also must use plasticizer.The kind of plasticizer is many, and sorbitol is arranged, glycerine, triethanolamine, polyethylene glycol, polyoxyethylene resin, polyvinyl alcohol etc.By investigating, find that these plasticizer performances are more or less the same, consider that from price use sorbitol relatively good, the ratio of it and film forming agent is 1: 4-8.
For the bigger agricultural chemicals of solvability in water miscible or the water, under the normal temperature agricultural chemicals of liquid perhaps, only need add emulsifier during emulsification and just can realize emulsification well.But for both water insoluble, be insoluble to the solid pesticide of oil again, when emulsification, preferably add a spot of wetting agent.In the coating agent for seed of being invented, added the 0.2-0.8% wetting agent and drawn back powder, with quick humidification and the dispersion that helps the solid pesticide particle.For the particulate that makes agricultural chemicals can stably suspend in water for a long time, in prescription, added 3-10% farm chemical emulgent phenethyl phenol polyethenoxy ether+calcium dodecyl benzene sulfonate, the ratio of the two is 1-3: 1; In order to increase bactericide and little fertile ability of infiltrating seed, also added the penetrating agent JFC of 1-5%.
In kind of the manufacturing process of clothing agent, owing to used surfactant and film forming agent, often produce a large amount of foams and be unfavorable for grinding and pulverizing.In order to reduce the foam of seed coating medicine manufacturing process, do the generation that defoamer can suppress foam effectively with the silicone emulsion of 0.1-0.3%.In addition, make coating agent for seed suspension become unstable in order to prevent and treat multigelation, the special polyalcohols antifreezing agent that in prescription, has used 4-8%, the antifreezing agent that can select for use has ethylene glycol, and propane diols and glycerine consider that from price spent glycol is optimum.
In order to overcome the dry slow shortcoming of coating agent for seed in the past, the special 5-15% low-carbon alcohols solvent that in prescription, added.That can adopt has ethanol and an isopropyl alcohol etc., considers that the latter's volatility and organic-dissolvable are higher than ethanol, selects for use isopropyl alcohol better.Aposematic use is in order to point out people's seed treated, can not to eat again; Whether simultaneously can also examine or check seed and wrap evenly, addition is generally prescription total amount 0.3-0.9%.Although this compound has certain antimicrobial effect,, in order to prevent possible sex change, still in prescription, added preservative.The kind of preservative has a lot, as parabens, and Sodium Benzoate, potassium sorbate, triumphant loose CG, benzisothiazole-3-ketone etc.The addition of preservative should decide according to its normal usage amount separately, as uses triumphant loose CG, and addition is 0.02%, as uses benzisothiazole-3-ketone, and then addition is 0.1%.
