Description
Technical field
The present invention relates to a kind of Semen Tritici aestivi special pesticide, diseases prevention, strong sprout, the multifunctional suspending seed-dressing agent of volume increase, belong to pesticidal preparations
Technical field.
Background technology
Semen Tritici aestivi is the cereal crops of China's total output second.Semen Tritici aestivi easily affected by adverse weather and disease at Seed germinating and growing at first days and
The phenomenon that emergence rate is low occur, after wheat during jointing stage, banded sclerotial blight, full rot fall ill heavier, growth promoter later stage aphid generation phenomenon
Ratio is more serious, and these problems result in the degradation of yield and quality of wheat.Therefore, it is effectively improved seed vitality, cultivates and strengthen
Seedling, raising Resistance of Wheat To Adversity, effectively preventing and treating sprout term disease and Later growth aphid damage seem increasingly important.
In recent years, wheat seed dressing agent, owing to saving the plurality of advantages such as medicine, saving of labor, environmental protection, is increasingly paid attention to by wide farmers,
There is also multiple different types of wheat seed dressing agent in the market.Wheat seed coating agent is by the effective ingredient such as insecticide, antibacterial
And auxiliary agent is ground, mix, directly or after dilution, be coated on the surface of the seed can be formed and there is some strength and permeability
Protecting film.
Seed coat agent containing farm chemical ingredients can effectively prevent and treat Wheat Diseases And Insect Pests.Seed coat agent scalable plant containing plant growth regulator
Growth conditions, it is possible to the synthesis of various materials and transhipment in regulation and control plant.Seed coat agent containing various nutritional labelings can improve little
Wheat emergence rate, make Semen Tritici aestivi formed strong sprout, improve Resistance of Wheat To Adversity.
Presently disclosed wheat seed coating agent, typically contains insecticide, antibacterial, plant growth regulator, trace element etc. 4 kinds
One or more in composition, as Chinese patent literature CN103609590A (application number: 201310500654.6) discloses one
Plant and improve wheat seeding rate and the seed dressing of wheat yield, although this invention has parasite killing, sterilization, plant growth regulating, nutrition concurrently
Etc. effect, and containing a great number of elements phosphorus and potassium, but it is prone to the chelated microelement absorbed without Semen Tritici aestivi, and alphamethrin
Strong toxicity, uses year after year, and potential hazard is bigger.
It is a kind of starch base compound seed coating material that CN104892258A (application number CN201510342279.6) discloses, including living
Property composition and film former, the mass parts composition of described active component is as follows: antibacterial 4-6 part, insecticide 4-6 part, salicylic acid
0.02-0.08 part, potassium dihydrogen phosphate 0.12-0.48 part, heteroauxing 0.02-0.06 part, trace element solution 0.2-0.6 part, point
Powder 0.02-0.06 part, attapulgite clay 5-10 part；The chemical antibacterial of this invention employing and insecticide, be low toxicity low residual
The medicament stayed, and a rot, droop and insect in seedling stage are had preferable prevention effect, with the addition of etherification starch, acetic acid fibre
Dimension element ester, chitosan, polyvinyl alcohol, the compounding use of graft starch, have superpower water absorbing properties；Increase caking property, film forming
Property.But this invention function is based on sterilization, and trophic function is auxiliary, does not focuses on the raising of crop anti-adversity performance, and seed coat agent is dense
Spend on the low side.
CN102126887A (application number CN201010560855.1) discloses a kind of seed dressing, and described seed dressing contains following
The component of weight portion: hydroscopic high-molecular resin 4-6, tetramethyl 1,3-propanedicarboxylic acid 0.4-0.6, thiram 8-12, carbofuran 8-12, phosphorus
Acid dihydride potassium 8-12, trace element and fulvic acid 8-12, this seed dressing is applicable to multiple kinds of crops and industrial crops, drought resisting, rush
Plant growth is effective, long action time.This invention strengthens emphatically crop drought resistance ability, preventing and treating subterranean pest-insect, promotes that crop is raw
Long effect, but do not have clear and definite effect in terms of, volume increase degeneration-resistant crop.
Floating type seed coat agent is one of highly important dosage form in modern agriculture, the environment-friendly type agent that Ye Shi FAO (Food and Agriculture Organization of the United Nation) is recommended
Type, its dispersibility and plate-out ability are relatively good, and suspensibility is high, and the ability sticking to Semen Tritici aestivi surface is stronger, resistance of rainwater washing against,
With water as disperse medium, the problem such as the inflammable and poisoning not produced by organic solvent, and without dust harzard, to operator with
Environmental security, also has that particle is little, active surface is big, penetration is strong, low cost, drug effect high.Under existing situation,
Integrate solution pest and disease damage, nutrition in strong sprout, high-efficiency multi-function seed coat agent degeneration-resistant, that increase production await developing further.
Summary of the invention
Degradation under wheat yield, quality is caused for Wheat Seedling disease, nutritional deficiency and the infringement of the middle and late growth stage wheat aphid, adverse circumstance etc.
Problem, the present invention provides a kind of multifunctional suspending seed-dressing agent being integrated containing pesticide, nutrient substance and plant growth regulator, can
To realize planting efficient saving of laborization, it is ensured that Semen Tritici aestivi finally realizes high and stable yields.
Summary of the invention:
The Semen Tritici aestivi multifunctional suspending seed-dressing agent of the present invention is by pesticide activity component imidacloprid and CGA-173506, nutrient substance biphosphate
Potassium, potassium fulvate, chelated zinc, Chelated Manganese and chelated copper, boric acid, plant growth regulator, film former, wetting agent, dispersion
Agent, thickening agent, antifreezing agent, defoamer, warning coloration and distilled water composition, be that a kind of collection solves pest and disease damage, nutrition in strong sprout, resists
The inverse multi-function seed coating agent being integrated with volume increase.
