Abstract
The present invention relates to insecticide composition which belongs to the technical field of composite pesticide. The insecticide composition is characterized in that the insecticide composition contains two kinds of effective components of the following weight percentage content: 0.1 to 6.0% of hexaflumuron, and 5 to 40% of triazophos. The insecticide composition utilizes the characteristics of low toxicity and long validity periods of the hexaflumuron and the characteristics of good quick effectiveness, low cost, etc. of the triazophos; synergy performance is obvious, co-toxicity coefficients achieve 283.8 to 341.7, disinsection spectra are wide, quick effectiveness and validity periods are good, and the cost of the insecticide composition is lower than 1/2 of the cost of the hexaflumuron through recompounding the hexaflumuron and the triazophos, and the insecticide composition can be used for preventing and curing lepidopterous pests of crops, such as paddy rice, cotton, vegetables, etc.
Description
[technical field]
The invention belongs to the composite pesticide technical field, be specially a kind of insecticides.
[background technology]
Fluorine bell urea (have another name called lid and loose, Hexaflumuron, XRD-473, Dowco-473), and its chemical name: N-[(3,5-two chloro-4-(1,1,2,2-tetrafluoro ethyoxyl) phenyl amino) carbonyl]-2,6-difluoro benzamide, molecular structural formula is:
Be dissolved in polar solvent, solvability is 27 micrograms per litre in water, and is stable to light.To the higher mammal low toxicity: big white mouse acute oral LD
50Greater than 5000 mg/kg; Acute through skin LD
50Greater than 2000 mg/kg, acute suction LD
502.5 mg/kg.High malicious to fish: rainbow trout LD
50(96 hours) are greater than 0.032 mg/litre.Eyes there is serious spread effect.Fluorine bell urea is the insect hormone insecticides, in the world the 4th generation agricultural chemicals, suppress insect and cast off a skin and food speed, based on stomach poison function, have action of contace poison concurrently, and ovicidal action arranged.Its quick-acting is poor, and the lasting period is long, is mainly used in control Lepidoptera, Homoptera and Diptera pest.
Hostathion (having another name called triazophos), its chemical name: O, O-diethyl-O-1-phenyl-1,2,4-triazole-3-base thiophosphate, molecular structural formula is:
Belong to one of organophosphorous pesticide, not soluble in water, dissolve in multiple organic solvent.Toxicity to higher mammal is medium: big white mouse acute oral LD
5082 mg/kg; Acute through skin LD
501100 mg/kg.Poisonous to honeybee, to ichthyism, carp LD
50(48 hours) about 1 mg/litre.Hostathion is broad spectrum insecticide, miticide, kills the effect of nematode in addition.Have stomach toxicity and action of contace poison, plant tissue is had permeability.Quick-acting is good, and the lasting period is shorter, domestic aphid and the lepidoptera pest that is widely used on control paddy rice, cotton, the fruit tree.Hostathion is the pesticide species that China's the nineties is gone into operation, and is one of principal item that replaces high-toxic pesticide (as acephatemet) at present, and the agricultural chemicals price is lower.Domesticly be used to prevent and treat the 70-80% that the snout moth's larva of rice, rice leaf roller account for output.
[technology contents]
The object of the invention is to overcome above-mentioned two kinds of insecticides deficiency of use separately, integrates both advantages, and is composite through rationally, and a kind of technical scheme of insecticides is provided.
Described a kind of insecticides is characterized in that containing two kinds of active princlples of fluorine bell urea and Hostathion, and weight percentage is: fluorine bell urea: 0.1-6.0%, Hostathion: 5-40%.
Described a kind of insecticides is characterized in that containing fluorine bell urea: 0.5-5%, Hostathion: 5-30%.
Described a kind of insecticides is characterized in that containing fluorine bell urea: 1-4%, Hostathion: 10-30%.
Described a kind of insecticides is characterized in that containing fluorine bell urea: 1-3%, Hostathion: 10-25%.
Described a kind of insecticides is characterized in that containing fluorine bell urea: 1-2%, Hostathion: 10-20%.
Described composite pesticide preparation can be a missible oil, removes the fluorine bell urea, the Hostathion active princlple that contain said ratio, and surplus is conventional solvent, emulsifier.Also can be made into water (little) emulsion.Described solvent, emulsifier and content proportioning are the known routine techniques of those skilled in the art, do not repeat them here.
Preparing process is: by said ratio fluorine bell urea and the former medicine of Hostathion are used dissolution with solvents respectively, mix and stir, add emulsifier again, stir, active constituent content is carried out in sampling and emulsifiability detects, and refills the bottle packing.
Described insecticides, utilize the low toxicity of fluorine bell urea, the lasting period is long, utilizes Hostathion quick-acting good, characteristics such as low cost, by above-mentioned composite, synergy is obvious, and co-toxicity coefficient reaches 283.8-341.7, insecticidal spectrum is wide, quick-acting and lasting effect are all good, and cost is lower more than 1/2 than fluorine bell urea, can be used for preventing and treating the lepidoptera pest of crops such as paddy rice, cotton and vegetables.
[embodiment]
Prescription one: fluorine bell urea: 1%, Hostathion: 14%, surplus is conventional solvent, emulsifier.
Prescription two: fluorine bell urea: 1.5%, Hostathion: 13.5%, surplus is conventional solvent, emulsifier.
Prescription three: fluorine bell urea: 2%, Hostathion: 13%, surplus is conventional solvent, emulsifier.
Described solvent is: dimethyl formamide, pyridine, acetonitrile, ethyl acetate, methyl alcohol, dimethylbenzene etc.
Described emulsifier is: agricultural newborn 0201B, 0203B etc.
Preparing process as previously mentioned.
Field control effectiveness test through how, 15% fluorine bell urea, triazophos emulsifiable solution are prevented and treated rice-stem borer, in Hubei, every mu of usefulness 60,70 and 80ml, control efficiency is respectively 90.42%, 96.15% and 95.03%; The effect of control rice leaf roller is respectively 97.43%, 99.0% and 99.72%.The Zhejiang Changshan, every mu of medication 60,70 and 80ml reach 91%, 96.7% and 87.5% respectively to the striped rice borer preventive effect; The rice leaf roller preventive effect is reached 70.24%, 82.65% and 86.33% respectively.In Hubei, control paddy stem borer every mu of medication 60,70 and 80MI, control efficiency is respectively 80.03%, 89.54% and 95.08%.More than test all increases 5-10% than single preventive effect with fluorine bell urea or Hostathion.
