Description
Technical field
The invention belongs to pesticide sterilizing composite field, and in particular to be a kind of containing fluorobenzene ether amide and kasugarnycin
Composition pesticide and application thereof.
Background technology
Rice blast is one of rice disease of whole world rice region harm most serious.The disease throughout the year can be to paddy rice
Cause harm, its harm has seedling rice blast, leaf pest, pulvinus pest, section rice blast etc. throughout each position of paddy rice, causes paddy rice within 1 year
Underproduction 10-20%.In China's occurring area more than 3,800,000 hectares, year loss paddy reaches several hundred million kilograms to the disease.At present, water
The utilization of the anti-pest kind of rice and the use of chemical pesticide are still the preventing and treating effective measure of rice blast, but because of anti-pest kind
The toxicity and cause of disease of unification, the complexity and pathogenic diversity of physiological races of rice blast fungus heredity, and chemical pesticide
The resistance to the action of a drug of bacterium, Rice Resistance pest kind and chemical pesticide are used and are all subject to certain restrictions in production, therefore, research and development are effective
Preventing and treating rice blast turn into hot research direction at present.
Fluorobenzene ether amide（Exploitation code name Y13149）It is new succinate dehydrogenase inhibitors, to the late blight of potato, water
The sheath and culm blight of rice, powdery mildew etc. have efficient sterilizing activity, with Uptake and translocation, and with the low spy of resistance to rainwater shower, consumption
Point, preventive effect does not interact anti-apparently higher than like product thifluzamide, the bactericide with most of bactericide in the market
Property, while especially it has the bactericidal activity of wide spectrum, can prevent and treat the multiple diseases in various crop, therefore as grinding at present
Study carefully focus, fluorobenzene ether amide structural formula is as follows：
。
Kasugarnycin by springtime streptomycete (Streptomyceskasugaensis) produced by, belong to aminoglycoside antibiosis
Element, is a kind of low toxicity, interior habit bactericide.Since the research and development, it is just widely used in kasugarnycin in Asia and South America
Agricultural.Its preventing and treating to rice blast (including leaf pest, rice head pest, paddy pest) etc. is especially pronounced, typically can reach more than 80%.
Moreover, the applicable crops of kasugarnycin can prevent also including potato, cucumber, celery, sorghum, capsicum, Kidney bean, oranges and tangerines etc.
Control the beet life tail spore on beet, the carrot soft Erwinia on potato, the pseudomonas on Kidney bean, the vacation list on cucumber
Spore bacterium, leaf muld of tomato, cucumber bacterial angular leaf spot etc..But due to long-term use cause it is obvious to the prevention effect of rice blast under
Drop, its consumption rises significantly, and prevention effect is greatly reduced.
The pesticide activity component of the different mechanisms of action is compounded, is had the advantages that small investment, R＆D cycle are short, especially
It is that composition pesticide of the exploitation with synergistic function more turns into the focus studied at present, therefore, researcher both domestic and external is confused
Confusingly strengthen research and development capabilities.Present inventor exactly under such technical background, by substantial amounts of toxicity screen and
Field control effectiveness test, is found surprisingly that and is compounded fluorobenzene ether amide and kasugarnycin, to various works in certain scope
Thing disease has obvious synergistic function, and especially preventing and treating rice blast has excellent prevention effect, by entering one
Step research completes the present invention.At present, there is no the relevant report compounded on fluorobenzene ether amide and kasugarnycin.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided a kind of applied widely, low cost, prevention effect
Good pesticide sterilizing composite, the pesticide sterilizing composite has significant Synergistic in the range of certain compound proportion
Effect.
Application another object of the present invention is to provide the pesticide sterilizing composite, the pesticide sterilizing composite is wide
It is general suitable for preventing and treating Cereal, melon and fruit and crop disease, be particularly suited for preventing and treating rice blast, late blight of potato etc..
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of pesticide sterilizing composite, its active component includes fluorobenzene ether amide and kasugarnycin, wherein, fluorobenzene ether amide and spring
The weight ratio of thunder mycin is 30:1-1:20, wherein, the weight ratio preferably 20:1-1:10.
Further, the weight percentage of active component is 5-90%, preferably 10- in the pesticide sterilizing composite
60%, remaining is the auxiliary element of routine in formulations of pesticide processing, the content of specific active ingredient and the close phase of the species of formulation
Close, it is also relevant with the mixed ratio and synergistic effect degree of another compound with a kind of compound, while also sick with target
Evil is relevant.
Further, bactericidal composition of the invention is by being aided with the conventional auxiliary element in Pesticide formulation, for example
Surfactant and/or carrier/filler, the surfactant can be dispersant, wetting agent, stabilizer, thickener, bonding
One or more in agent, disintegrant, defoamer, the bactericidal composition can be processed into suitable agricultural production appointing of using
Anticipate a kind of formulation, for example, can be any in water dispersible granules, wettable powder, suspending agent, microemulsion, aqueous emulsion, suspension emulsion
Kind.
Further, in bactericidal composition of the invention can also contain other agricultural active compositions, including but not limited to its
Its bactericide, Insecticides (tech) ＆ Herbicides (tech), safener, synergist, plant growth regulator, fertilizer, biostimulant etc..
Further, bactericidal composition of the invention can be that each material has been in composition with finished product preparation form offer
Mixing, it is also possible to provided with unit dose form, directly mixed in proportion in bucket or tank using preceding, it is dense required for being then diluted to
Degree.
Further, bactericidal composition of the invention can be with itself concentration form or with general conventional formulation shape
Formula is used, property according to target disease it is different using pourings, spraying, atomizing, dress seed, spread fertilizer over the fields or brushing method, its use is total
Active ingredient usage amount changes according to weather condition, crop condition or application process.
Compared with prior art, pesticide sterilizing composite of the invention has the beneficial effect that：
1st, fluorobenzene ether amide and the kasugarnycin mechanism of action are different in bactericidal composition of the invention, and both mutually compound not
Conflict can be produced, synergistic function can be produced, reduce pesticide dosage, reduce drug cost, and can overcome and/or delay
The drug-fast generation of pathogen；
2nd, bactericidal composition drug effect of the invention is than being used alone prevention effect more preferably, and dosage is lower, is widely used in anti-harnessing the river
The crop diseases such as rice, potato, tomato, are particularly suited for preventing and treating rice blast, late blight of potato etc..
Bactericidal composition security of the invention is higher, and crop is produced without poisoning, and beneficial natural enemy is had no adverse effects.
