Abstract
Purposes the invention discloses octyl trichlamide as active constituent in terms of control of nematode, belongs to technical field of pesticide.The invention has the benefit that the purposes the invention discloses octyl trichlamide as active constituent in terms of the control of nematode especially in terms of plant nematode prevention and treatment, mematocide using octyl trichlamide as active constituent, with excellent preventive effect, and can delay the resistance development of nematode when preventing and treating nematodiasis.
Description
Technical field
Use the present invention relates to technical field of pesticide more particularly to octyl trichlamide as active constituent in terms of control of nematode
On the way.
Background technique
Nematode belongs to Nemathelminthes Nematoda, also known as worm, is a kind of low invertebrate, and figure is small,
It is observed that, soil, fresh water are usually lived in, in seawater, some of them can colonize in plant, cause disease below microscope
Evil, such is known as plant nematode.Plant nematode is China's grain, vegetables, important cause of disease in industrial crops production
Absorption of the plant to moisture and nutrition can be greatly reduced in the direct feeding of object, nematode, and the secretion during nematode metabolism is also
The cell and tissue that host plant can be stimulated cause plant lopsided, and wound caused by feeding is returned phytopathogen invasion and provided
Convenience declines the agricultural product underproduction and quality.Global Important Economic crop is up to several every year because losing caused by nematodiasis
10000000000 dollars, the underproduction has become the important threat of China's agricultural production every year up to 12% caused by China causes harm because of nematode
One of.
Plant nematode mainly includes a Turbatrix, Ditylenchus, Heterodera, Meloidogyne, quasi- sliding sword line
Eimeria, Bursaphelenchus, root needle nematode etc..More serious nemas, which occurs, for China the various crops such as cucumber
Root knot nematode disease, soybean cyst nematode, wheat anguina disease, Potato Rot Nemotode disease, aphelenchoides besseyi disease, pine line
Parasitosis, citrus Tylenchulus Semipenetrans disease etc..In actual agricultural production process, application chemical agent is prevention and treatment plant nematode diseases
The most effective means, but the problem of being easy to produce by chemical prevention is the generation of pest resistance to insecticide, and effect is preferable at present
Chemical prevention medicament it is optionally few, wherein most nematicide has compared with high toxicity people and animals, some kinds to crop also
Phytotoxicity.
Octyl trichlamide is a kind of environment-friendly type amino acids high molecular polymer fungicide, can generate ionization in aqueous solution,
Strong electropositive is contained in hydrophilic group part, and absorption is usually in all kinds of pathogens of negative electricity, to inhibit fungi, bacterium, disease
The breeding of poison solidifies germ protein, is denaturalized germ enzyme system, in addition the film that polymer is formed plugs the micro- life in this part
The ion channel of object makes its death by suffocation immediately, to reach optimal bactericidal effect, broad-spectrum has absorbability and pole
Strong permeability also has upward, downward, biaxial flexural member effect, has efficient, low toxicity, wide sterilization spectrum, environmental-friendly feature,
There is good preventive effect to most fungies, bacterium, virus.Experiment is surveyed it is now discovered that octyl trichlamide, which has nematode, preferably kills work by raw
Property, and be not easy to induce nematode generation resistance, it is conducive to lasting control, to plant safety height, in nematode especially phytotrophy line
It is significant in the prevention and treatment of worm, and do not have the report of this aspect, octyl trichlamide belongs to the activity of nematode to be found for the first time.
Summary of the invention
Purposes the present invention provides octyl trichlamide as active constituent in terms of control of nematode, it is especially raw in agricultural
Producing aspect has excellent preventive effect to plant nematode, can delay the resistance development of nematode.
Purposes of the octyl trichlamide as active constituent in terms of control of nematode.
Octyl trichlamide is preparing the purposes in mematocide as active constituent.
The mass fraction of octyl trichlamide described in the mematocide be 0.1%-90%, remaining for pesticide adjuvant at
Point.
Preferably, the mass fraction of octyl trichlamide described in the mematocide is 0.5%-80%, remaining is auxiliary for pesticide
Auxiliary component.
The dosage form of the mematocide is missible oil, suspending agent, wettable powder, water dispersible granules, aqueous emulsion, micro emulsion
Agent, soluble concentrate, granule or microcapsule formulations.
The insecticide-applying way of the mematocide is pouring root, leaching root, soaks seed, spread fertilizer over the fields, ditch spread, cave apply, be sprayed, infuse and do
It is one or more of.
The nematode can be the parasitic nematode in Cereal, veterinary antibiotics or ornamental plant.
The beneficial effects of the present invention are: the invention discloses octyl trichlamide as active constituent in terms of control of nematode especially
The purposes of plant nematode prevention and treatment aspect, the mematocide using octyl trichlamide as active constituent have when preventing and treating nematodiasis
Excellent preventive effect, and the resistance development of nematode can be delayed.
Specific embodiment
Octyl trichlamide is a kind of environment-friendly type amino acids high molecular polymer fungicide, has efficient, low toxicity, wide sterilization spectrum, ring
