Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of disinsection prophylaxis composition on crop pests and disease of a kind of fluorine-containing azoles ring bacterium amine and anabasine.
Background technology
Fluorine azoles ring bacterium amine (sedaxane) is a kind of new and effective low toxicity bactericide, causing effect, being mainly used in preventing and treating smut by suppressing germ succinate dehydrogenase.
Imidacloprid, Diacloden, thiacloprid, clothianidin all belong to Novel tobacco alkaloid compound, act on the nicotinic acetylcholine receptors of insect, having stronger interior suction, tag and stomach poison function, is the specific drug of controlling sucking insects and disease and chewing type insect and disease.
Seed coating technology is a kind of very universal seed treatment new technology grown up in traditional seed soaking or seed dressing technical foundation.By seed that is dry or moisture state; wrapped with compositions such as the agricultural chemicals containing binding agent or fertilizer; make to form the protective layer with certain function and coated intensity outward at seed; this process becomes seed pelleting; the composition wrapped in outside seed is referred to as seed coat agent, is a kind of for crop or other plant seed treatment, the pesticidal preparations with film forming characteristics.Seed coat agent great advantage is outside seed, to form one deck more firmly film.Seed coat agent imbibition and not dissolved in soil, allows normally germinate required moisture and air of seed to pass through, the material slow releasing such as contained agricultural chemicals and seed manure.So, seed coat agent have kill soil insect, seedling stage insect, control sprout term disease and systemic disease, improves percentage of seedgermination, promotes seedling healthy growth, the effects such as less seed consumption, finally reach preventing disease pest control, strong sprout of keeping a full stand of seedings, improves the object of output.
The problem that prevention and elimination of disease and pests the most easily produces is drug-fast generation, and secondly for control spectrum is single, repeatedly dispenser when peasant uses, cause environmental pollution serious, crop residue of pesticide are large, unfavorable to human health.Applicant is by the bactericide of the different mechanism of action and pesticide compositional, reach the two anti-object of a spray, effectively the various disease of control crop, expand the control spectrum of former single dose, do not directly act on crop, and residue of pesticide are decomposed between the crop growth stage, to crop noresidue or low-residual, to eater's safety, and synergistic effect is remarkable, Environmental compatibility is fabulous, considerably reduces pesticide usage amount, reduces the dispenser cost of peasant.
Fluorine azoles ring bacterium amine, Imidacloprid, Diacloden, thiacloprid, the resistance that clothianidin single dose Long-Time Service may bring occurs, degradation problem under drug effect, the disinsection prophylaxis composition that the present invention proposes contains the composition pesticide of fluorine azoles ring bacterium amine, by fluorine azoles ring bacterium amine and Imidacloprid, Diacloden, thiacloprid, clothianidin is composite, add appropriate auxiliary agent and make various formulation, for preventing and treating the application of insect on crops and disease, be mainly used in preventing and treating cutworm, wireworm, grub, thrips, aphid, midge worm, aleyrodid, rice fulgorid, rice leaf roller, striped rice borer, paddy stem borer, longicorn, scale insect, tea lesser leafhopper, cotton bollworm, cotton boll resembles, beet armyworm, rice leafhopper, diamond-back moth, smut, rice blast, root rot, damping off, the effect of powdery mildew or epidemic disease is very outstanding, there is the effect that a spray two is anti-.

By table 11-14 can find out fluorine azoles ring bacterium amine and Imidacloprid, Diacloden, thiacloprid, the composite rear control maize head smut of clothianidin proportioning 1:100 to 80:1 time, synergy index is all greater than 1, both explanations mixture in 1:100 to 80:1 scope all shows synergistic effect, especially when fluorine azoles ring bacterium amine and Imidacloprid or clothianidin are at 10:1 to 1:30, fluorine azoles ring bacterium amine and Diacloden are when 20:1 to 1:25, fluorine azoles ring bacterium amine and thiacloprid are when 10:1 to 1:35, and synergistic effect is more obviously given prominence to.
Application Example three:
For examination disease: cotton black cutworm
Test medicine provides by Shaanxi Meibang Pesticide Co., Ltd..
Experimental scheme: through effective lethal concentration scope of preliminary experiment determination fluorine azoles ring bacterium amine Imidacloprid, Diacloden, thiacloprid, the former medicine of clothianidin and the two different ratio mixture.
The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.First by Toxicity Determination, synergy index is greater than 1 expression synergistic effect, is less than 1 for antagonism, is summation action, on this basis, then carries out field trial between equaling 1.
Computing formula is as follows:
According to investigation result, by following formulae discovery lethality and corrected mortality
Be dependent variable (y) by the probit value of corrected mortality, with the logarithm value of using dosage (gram of/kilogram of seed) be independent variable (x), input CASIOfx180p calculator, asks the LC of each medicament
50, LC
90, 95% confidence limit, b value, standard error SD, with Imidacloprid, Diacloden, thiacloprid, clothianidin for contrast medicament (toxicity index is for 1), calculate the relative virus force index of fluorine azoles ring bacterium amine Imidacloprid, Diacloden, thiacloprid, clothianidin, evaluate fluorine azoles ring bacterium amine Imidacloprid, Diacloden, thiacloprid, clothianidin to the biologically active of cotton black cutworm.With Imidacloprid, Diacloden, thiacloprid, clothianidin for insecticide, fluorine azoles ring bacterium amine is that synergist calculates synergy index.
LC when synergy index=medicament is alone
50lC when value/medicament adds synergist
50value.
