Description
Technical field
The present invention relates to a kind of suspension seed-coating agent and preparation method thereof, its active ingredient is ethiprole and fosthiazate.
Background technology
Ethiprole, that a kind of Phenylpyrazole insecticides, insecticidal spectrum are wide, to insect taking stomach poison function as main, have concurrently and tag and certain systemic action, its mechanism of action is to hinder the chloride metabolism of insect γ-aminobutyric acid control, therefore the important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleoptera are had to very high insecticidal activity, to crop without poisoning.This medicament can impose on soil, also can foliar spray.Impose on effectively chrysomelid, the wireworm of control of maize root and cutworm of soil.When foliage spray, diamond-back moth, imported cabbageworm, rice thrips etc. are all had to high-level preventive effect, and the lasting period is long.
Fosthiazate, agricultural nematocide, kills nematode scope wide, to root-knot nematode, pratylenchus, stem eelworm, Cyst nematode etc. have good control efficiency, and the motion of nematode is had to the very strong nematode power that encumbers and kill, and efficacy stability is effective.In plant, there is fine conduction, can effectively preventing in nematode invaded plants body, also can effectively kill the nematode in intrusive body.Simultaneously to overground part insect, as to aphid, tetranychid, thrips etc. also have the double effect of controlling.It is long to kill the nematode lasting period, and annual crop 2-3 month, perennial crop 4-6 month.
If two kinds of medicaments use separately, its property of medicine is single, and two kinds of composite reagents are as seed coat agent, can reduce dispenser cost savings resource, reaches the double effect of controlling of effect of holding concurrently.
Summary of the invention
In order to overcome the above problems, the present invention proposes a kind of suspension seed-coating agent that contains ethiprole and fosthiazate and preparation method thereof, object is that ethiprole and fosthiazate carry out composite its advantage of giving full play to.
In the present invention, the content of active ingredient is: ethiprole 1-55%, fosthiazate 1-65%; Preferably than being, ethiprole 5-40%, fosthiazate 5-40%.
In the present invention, active ingredient ethiprole and the fosthiazate total content mass ratio in preparation is 1-80%, preferably than being 10-50%.
The formula of the suspension seed-coating agent the present invention relates to is:
Ethiprole 1-55%
Fosthiazate 1-65%
Emulsifier 3-5%
Dispersant 2-5%
Film forming agent 4-8%
Antifreezing agent 2-5%
Thickener 0.1-3%
Warning colouration 0.1-0.5%
Defoamer 0-0.3%
Water surplus
The preparation method of this seed coat agent is: take each raw material by above proportioning, then heat water to 50 DEG C, film forming agent and warning colouration stirring are added, solvent becomes film forming solvent completely, again active ingredient, emulsifier, dispersant, antifreezing agent, thickener etc. are dropped into ball mill grinding 2-5 hour, make particle diameter all below 5 μ m, can make.
The seed coat agent stable chemical nature the present invention relates to, 54 ± 2 DEG C of condition lower seal storages are after 14 days, heat storage resolution ratio is less than 5%, suspensibility is more than 90%, reach the international regulation for seed coat agent, by adding special film forming agent, for seed pelleting, there is the lasting period long, safety and low toxicity, synergy outstanding feature.Can be for the soil insect of the crops such as control peanut, corn, wheat, paddy rice as grub, mole cricket, wireworm, various nematodes etc.; The suckings pest such as control aphid in seedling stage, small brown rice planthopper, thrips, powdery mildew, leafhopper.

Ethiprole proportionings different from fosthiazate are to capsicum root-knot nematode co-toxicity
Reagent agent
The former medicine of 95% ethiprole, the former medicine of 93% fosthiazate, above-mentioned former medicine provides by research and development centre of Qingdao Hailir Pesticides and Chemical Co., Ltd..
Experimental subjects
Capsicum root-knot nematode (
meloidogyne incognita)
Evaluation method is liquid infusion method.Active component adds appropriate acetone solution on request, is then diluted to the mother liquor of 10000ppm as testing liquid by purified water.Then mother liquor is diluted to 2 times of concentration of experimental concentration, adds 100 μ l, and then add the root-knot nematode suspension of equivalent in each hole of 96 orifice plates, at 25 DEG C, place after one week with the nematode death toll in each hole of microscopic examination and survival number dark place.
table 6 drug effect computational methods:
The theoretical control efficiency (%) of composition pesticide, use Colby formula determine and with the effect comparison of observing:
Colby formula: E=X+Y-X*Y/100
E: when active components A working concentration in composition is a, the theoretical preventive effect of composition when active component B working concentration is b,
X: preventive effect when active components A working concentration is a,
Y: preventive effect when active component B working concentration is b.
When exceeding theoretical preventive effect explanation composition, the preventive effect of observing has synergistic effect.
table 7 ethiprole and fosthiazate single dose are to pepper root tie lines worm Toxicity Determination
table 8 ethiprole and fosthiazate complex preparation are for pepper root tie lines worm Toxicity Determination
Result of the test shows, the composite control of ethiprole and fosthiazate root-knot nematode has obvious synergistic effect.
