Abstract
The invention discloses a process for producing a suspended seed coating. The production process comprises the steps of burdening, mixing, stirring, grinding and the like. The suspended seed coating comprises thiram, carbofuran and triadimenol according to a certain mass ratio. With adoption of the technical scheme, after the produced suspended seed coating is mixed with seeds, effects of regular seedlings, robust seedlings and promotion of root system growth can be achieved, and lodging resistance of corns is greatly improved. The seeds can be used while being mixed, the seeds are dried within three minutes and are not needed to be aired, a bin gate is not blocked, the seeding operation is good, seedlings are not in shortage, and waste is avoided. In addition, the suspended seed coating produced by the invention is quick in film formation, uniform in coloring and transparent, a film layer is not dissolved in water and swells along with expansion of the seeds, but cannot be cracked, drugs slowly release, the drug effect is persistently exerted, the suspended seed coating is safe to use, and the conditions that the seedlings grow late, the seeds are covered and rotted, germination and growth are influenced and the like are avoided. Moreover, the process is successfully used in multiple domestic seed production enterprises, the seed drying process after coating is directly eliminated for the enterprises, the seeds are packaged while being mixed, so that the seed production cost is greatly reduced.
Description
Technical field
The present invention relates to pesticide producing field, specifically, relate to a kind of production technology of suspension seed-coating agent.
Background technology
Along with wideling popularize of straw-returning, corn soil insect is becoming increasingly rampant, especially wireworm large area is broken out, the seed coat agents such as Imidacloprid, Diacloden, beta-cypermethrin have certain effect to grub, cutworm, mole cricket etc., but to the control efficiency extreme difference of wireworm, cause corn to drop in production over a large area, in wireworm control, carbofuran effect is good.In good fortune gram alcohol, carbofuran content is 8%, and the control efficiency to wireworm after seed dressing is obvious, and emergence rate improves 15.2% than contrast field.
In good fortune gram alcohol dressing field, the generation of aphid, thrips, small brown rice planthopper reduces respectively 95.7%, 93.4%, 98.3% than the contrast field of not dressing seed, and greatly reduces the occurrence probability of MRDV.
Maize diseases has head smut, root rot, leaf spot, bacterial wilt, smut etc., wherein head smut is difficult to control most, both at home and abroad mostly all taking Tebuconazole, fludioxonil, Metalaxyl-M, tmtd, carbendazim, carboxin, Triadimenol as main, the composition wherein behaving oneself best is Triadimenol, remarkably productive at maize head smut, simultaneously also good other diseases of control of maize.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, a kind of suspended seed coating agent producing process is provided, and the suspension seed-coating agent of this explained hereafter has that film forming is fast, uniform coloring is bright, rete is met water and can not be dissolved, expand, do not break, sustained release, bring into play lastingly the feature of drug effect with the expansion of seed.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of suspended seed coating agent producing process, is characterized in that, described production technology comprises the following steps:
A, batching, choose tmtd, carbofuran, Triadimenol, wetting dispersing agent, xanthans, ethylene glycol, film forming agent, rhodamine toner and water, and its mass percent is followed successively by: 11.2: 8: 0.8: 4: 0.15: 5: 4: 0.5: 66.35;
B, Jiang Shui add in reactor, then add in mass ratio wetting dispersing agent, and film forming agent and ethylene glycol, stir;
C, add tmtd in mass ratio, carbofuran, Triadimenol stirs;
D, add rhodamine toner to stir in mass ratio;
E, by the mixed liquor stirring be discharged in colloid mill, be ground to material evenly, without caking;
F, by colloid successively by the horizontal sand mill of 4 series connection, mixed material is milled to particle diameter below five microns;
G, with pump squeezing into modulation kettle from sand mill material out, in mass ratio xanthans is added in modulation kettle, open modulation kettle, modulation evenly, obtains suspension seed-coating agent.
Improve as one:
Described film forming agent is 10% aqueous solution of polyvinyl alcohol 1788.
As further improvement:
In described steps A-G, temperature is no more than 50 DEG C, and pressure differential is no more than 0.2MPA.
Owing to having adopted technique scheme, after the seed dressing of suspension seed-coating agent that the present invention produces, can play that seedling is neat, the effect of Miao Zhuan, promotion root growth, greatly improve the lodging tolerance of corn; And dress seed and can now mix existing use, 3 minutes dry kinds, without the kind of drying in the air, do not block up door, sow, are not short of seedling, do not waste; In addition, the suspension seed-coating agent film forming that the present invention produces is fast, and uniform coloring is bright, and rete is met water and can not be dissolved, expansion with seed is expanded, do not break, and sustained release, lasting performance drug effect, is used safety, there will not be seedling evening, vexed kind, rotten kind, impact to emerge, affect the situations such as growth; Duo Jia production of hybrid seeds enterprise is successfully used at home, has directly saved dry kind of process after dressing for enterprise, now mixes existing dress, greatly reduces seed production cost.
Embodiment
Embodiment: a kind of suspended seed coating agent producing process, taking the suspension seed-coating agent of producing double centner as example, described production technology comprises the following steps:
A, batching, choose 11.2kg tmtd, 8kg carbofuran, 0.8kg Triadimenol, 4kg wetting dispersing agent, 0.15kg xanthans, 5kg ethylene glycol, 4kg film forming agent, 0.5kg rhodamine toner and 66.35kg water;
B, 66.35kg water is added in reactor, then add 4kg wetting dispersing agent, 4kg film forming agent and 5kg ethylene glycol, stir;
C, add 11.2kg tmtd, 8kg carbofuran, 0.8kg Triadimenol stirs;
D, add 0.5kg rhodamine toner to stir in mass ratio;
E, by the mixed liquor stirring be discharged in colloid mill, be ground to material evenly, without caking;
