Abstract
The invention discloses a kind of corn seed coating agent, comprising active component be Boscalid, Difenoconazole, MTI-446 etc., the wherein mass ratio of Boscalid, Difenoconazole and MTI-446 is 20:1~1:10, balance of water.With the coating agent for seed of this component configuration according to pesticide-seeds ratio 1:2~1:There is good prevention effect to Maize in Earlier Stage pest and disease damage after 1000 coatings, hence it is evident that improve the indexs such as emergence rate, plant plant height, fresh weight, hence it is evident that be better than conventional coating agent.It is for the good coating agent of corn seed.This coating agent active compound is easy to get, low cost, and configuration is convenient.
Description
Technical field
The present invention relates to a kind of coating agent for seed, specifically a kind of corn seed coating agent of insect prevention prophyiaxis and promoting growth.
Background technology
China is second-biggest-in-the-world Maize Production state, and corn occupies very important in the sustainable development of China's agricultural
Status, seed vitality is increasingly paid close attention to by the people, how to ensure the vigor high of seed and becomes the focus of research.
Seed coat agent is that containing medicament and one layer of the outer bread of seed is promoted into growth regulatory substance " coat ", this layer of coat into
It is seed coat agent.Seed coat agent energy effectively preventing crops seedling stage pest and disease damage, hence it is evident that promote growth of seedling, environmental pollution journey can be reduced
Degree, dramatically increases the yield of crop.
Seed coat agent has applied many years in agricultural production, and it has a wide range of application, and cost performance is high.With drought resisting, insect prevention
Disease-resistant, increasing both production and income effect, especially to seedling stage insect, maize sheath blight, maize head smut etc., with preventing and treating effect well
Really, and well developed root system can be promoted, seedling is grown up strong and sturdy, so as to effectively improve the yield of crops.Mixed with general
Plant, soak seed, vexed kind of method is compared with other agricultural chemicals, the major advantage of seed coat agent has：
1st, with benefit higher：Seed coat agent forms a kind of diaphragm in outer covering of the seed, concentrates the efficacy of a drug, service efficiency
Height, saving of labor, time saving, material-saving.After being coated with seed coat agent, seed quality can be effectively improved, make to emerge it is neat, complete, strong be protected, together
When save seed, so as to greatly reduce production cost.
2nd, it is safe：It is hidden to use, do not hinder the world, be conducive to integrated control；Due to being seed pelleting, on plant
Persticide residue greatly reduces, and poisoning will not occur, and improves the security of the applications of pesticide；Seed pelleting is typically with warning
Color, has prevented grain, has planted regardless of will not typically be damaged to people and animals.
3rd, the drug effect phase is long：Seed coat agent typically all has the effect of slow release, and agricultural chemicals slowly discharges, do not exposed to the sun and rain and
High temperature influences, therefore the drug effect phase is long.Seed coat agent is close to seed, and the efficacy of a drug is concentrated, and utilization rate is high, thus than spraying, soil treatment, poison
The application methods such as soil save medicine, saving of labor, save and plant.
4th, effect is more：Seed coat agent be contained within insecticide, bactericide, plant growth regulator, fertilizer, rare earth etc. it is various into
Point, can be with one multiplex.Seed coat agent is hidden to be used, pollution-free to air, soil, does not hinder natural enemy, uses safety.
Existing corn seed coating agent external product is generally single dose, and controlling object is single, and home products quality is uneven, while
The product of insect prevention diseases prevention is few, and medicine component aging phenomenon is present, and is badly in need of new seed coat agent component.
The content of the invention
The invention provides a kind of corn seed coating agent, the coating agent for seed can be good at preventing and treating Maize in Earlier Stage disease pest
Evil, improves corn seed emergence rate, increases Seedling Height, root long, fresh weight and dry weight, reaches prevention early stage pest and disease damage, improves beautiful
Rice seed vitality, the purpose of increasing both production and income.
The technical scheme is that：
A kind of corn seed coating agent, it is characterised in that：By bactericide Boscalid, Difenoconazole, insecticide furan worm
Amine and auxiliary material are constituted, and the gross weight percentage composition of active ingredient is 1%~60%.
A kind of corn seed coating agent, it is characterised in that：By bactericide Boscalid, Difenoconazole, insecticide furan worm
Amine and auxiliary material are constituted, and the mass ratio of Boscalid, Difenoconazole and MTI-446 is 20:1~1:10.
A kind of corn seed coating agent, it is characterised in that：By bactericide Boscalid, Difenoconazole, insecticide furan worm
Amine and auxiliary material are constituted, and the mass ratio of Boscalid, Difenoconazole and MTI-446 is 5:1~1:1.
A kind of corn seed coating agent, it is characterised in that：The formulation of the composition pesticide is aqueous suspension seed coat agent, oil is outstanding
Floating seed coat agent or microcapsule suspension seed-coating agent.
Described corn seed coating agent, its application method is：By corn seed and coating agent for seed according to a certain percentage
It is well mixed, stored for future use after fully drying.
Remarkable result of the invention and advantage are：
The present invention has good coating effect to corn seed, there is obvious mutual promoting action between component, can be fine
Raising corn seed germination percentage, germinating energy, increase Seedling Height, root long, fresh weight and dry weight, meanwhile, the desinsection for being added
Bactericide can be good at preventing the pest and disease damage of Maize in Earlier Stage, reach strong sprout, growth promotion, anti-disease pest, the purpose of volume increase.
Bactericide is determined first (with Boscalid and Difenoconazole 5:As a example by 1, but ratio not limited to this, it is any can be with
The proportion associated is within protection scope of the present invention) with insecticide (MTI-446) to the synergic ratio of corn small brown rice planthopper
Example.According to two kinds of EC of medicament50The portfolio ratio of two medicaments is set by the abundant methods of Sun Yun, and according to co-toxicity coefficient CTC values, it is determined that closing
Suitable composition ratio.
Test objective thing is corn small brown rice planthopper, but not limited to this.Experiment uses glass-tube medicine embrane method, is made by different disposal and contained
Death toll of each treatment to corn small brown rice planthopper is investigated in medicine glass tube, respectively 4 repetitions for the treatment of.By the probit value and series of preventive effect
Linear regression analysis between the logarithm value of drug concentration, obtains the LC of each medicament50, co-toxicity coefficient is calculated according to the abundant methods of Sun Yun
(CTC) overall merit is made, and accordingly.CTC≤80 represent there is antagonism, and 80 ＜ CTC ＜ 120 are represented to have to be added and made
With CTC >=120 are synergistic effect.CTC value calculating methods are as follows：
The EC of CTC=A50* the EC of B50* 100/ (the EC of M50*(PA* the EC of B50+PB* the EC of A50)), wherein M represents mixture,
PA、PBMedicament A, the mass fraction of medicament B are represented respectively.
The indoor biometricses result of the Boscalid of table 1, Difenoconazole and MTI-446 and its compounding to small brown rice planthopper
Remarks：Medicament B is defined by 5000mg/L when CTC is calculated.
It can be seen from Table 1 that, medicament A and medicament B mixtures are 20:1~1:Show that certain synergy is made in the range of 10
With.CTC values are between 120~140.
With reference to embodiment, the invention will be further described, but not limited to this.
