Description
Technical field
The invention belongs to technical field of pesticide, and in particular to be that a kind of collaboration containing benzothiostrobin and prothioconazoles increases
Imitate composition pesticide and its method for preventing and treating corps diseases.
Background technology
Rice green smut alias green grass or young crops powder disease, pseudo- smut, belong to fungal disease.With some short haulm compact type rice varieties
Popularization and the raising of Fertilization Level, this disease occur more and more to protrude.The empty flat grain of sick fringe is dramatically increased, fall ill it is latter as can the underproduction
5%〜10%.False smut is main to be occurred in Rice Heading blooming stage, part grain on harm fringe, at least every fringe I 2, serious
Up to 20 30.Pests occurrence rule:Main sprouted with sclerotium between overwintered in soil, the August of next year 7 of this disease forms spore seat, spore
Multiple shell of ascus are produced on stroma, a large amount of ascospores of generation and conidium in it；Can also chlamydospore be attached on seed
Survive the winter, sprout to form conidium when condition is appropriate to the occasion.Spore is propagated by air-flow to be scattered, and floral organ and children are encroached in the paddy rice cut phase
Device, causes grain to fall ill.Studied according to Institute of Plant Protection of academy of agricultural sciences of Jiangsu Province, infection process is started from after pollen mother cell meiosis
With pollen mother cell influx time, and before and after pollen mother cell influx time this period be the important period infected.
Benzothiostrobin (English common name:Benzothiostrobin), it is the dilute bactericide of phosphate (phosphinium) ester of methoxy propyl, line grain
Body respiratory chain cytochrome b cl complex inhibitors, there is good security to beneficial organism and crop, low toxicity and to environment
It is friendly.It can be widely used for preventing and treating sclerotinia sclerotiorum, rice green smut, corn southern leaf blight, citrus maize ear rot and vegetables and melon and fruit class
The various crop fungal disease such as powdery mildew, downy mildew, gray mold, brown spot, scab.Have well to beneficial organism and crop
Security, low toxicity and environmentally friendly.Multiple field control effectiveness test shows：Benzothiostrobin can be used for preventing and treating multiple diseases
Preventing and treating, particularly shows excellent preventive effect to powdery mildew of cucumber and cucumber downy mildew, and its preventive effect is better than or sterilized with import
Agent Fluoxastrobin is suitable, but active compound cost, and mu drug cost is below Fluoxastrobin.
Prothioconazoles are low toxicity bactericide, are the triazole thioketone wide-spectrum bactericides that Beyer Co., Ltd develops, and it is acted on
Mechanism is to suppress the demethylation effect of the precursor of sterol in fungi, so as to play bactericidal action, the kind not only has fine
Systemic activity, excellent protection and root out activity, and the lasting period is long, to crop safety.Prothioconazoles are mainly used in preventing and treating standing grain
All wheat class diseases are almost all had by the multiple diseases on cereal crops such as wheat, barley, peanut, paddy rice and legume
Good prevention effect, such as wheat powdery mildew, banded sclerotial blight, leaf spot, false smut, moreover it is possible to prevent and treat the soil-borne disease of rape and peanut
Evil, such as sclerotiniose, dosage is generally per hectare 200g or so, under this dosage, and its activity is superior or equal to normal at present
The bactericide kind of rule.
In agricultural production, fungal disease is damage to crops growth principal element, and species is more, host range is wide, harm
Seriously.Control crop fungal disease is mainly by chemical prevention at present, and it is induction pathogen that long-term chemical, which prevents and treats inevitable outcome,
Develop immunity to drugs.Drug-fast generation causes medicament to decline disease-controlling effect, causes the agriculture underproduction.By two kinds or two kinds with
On agricultural chemicals single dose a kind of important way as pesticides application is applied in combination according to a certain percentage.Good compounded formula not only may be used
To expand pesticide control object and application, drug effect is improved, reduction toxicity, poisoning and residual can also overcome and slow down anti-
The property of medicine is produced.At present, it is not yet found that the relevant report compounded on benzothiostrobin and prothioconazoles.
The content of the invention
It is a kind of to Synergistic composition pesticide of the harmful fungoid with improvement activity present invention aims at providing.It is described
Synergistic composition pesticide prevention effect is good, composition is low, to crop safety.
Another object of the present invention is to provide the application of the Synergistic composition pesticide, the Synergistic agricultural chemicals
Composition can be used for preventing and treating false smut, rice blast, powdery mildew, downy mildew, sclerotiniose of multiple kinds of crops disease etc..
The Synergistic composition pesticide of the present invention is realized by tests below scheme：A kind of Synergistic agricultural chemicals group
Compound, it is characterised in that its active component at least includes benzothiostrobin and prothioconazoles.
Further, the benzothiostrobin and the weight of prothioconazoles ratio are 1:30-30：1, preferably 1：10-5：1.
Further, in the composition pesticide active component weight percentage be 2-80%, preferably 10-60%,
Remaining is agricultural chemicals auxiliary element conventional in Pesticide formulation, selected from surfactant and/or auxiliary agent, filler etc..
Further, composition pesticide of the invention can be prepared into arbitrarily by the conventional method in Pesticide formulation
A kind of formulations of pesticide, including but not limited to missible oil, wettable powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion, seed
One kind in inorganic agent.
Further, active component can be by applying or applying respectively benzene thiophene bacterium together in composition pesticide of the invention
Ester and prothioconazoles, or benzothiostrobin and prothioconazoles are applied successively.
Further, the application method of composition pesticide of the invention is that it is true that the composition pesticide is acted on into cause of disease
In bacterium and/or its living environment, or plant, plant parts, seed, soil.
Further, composition pesticide of the invention can be that each material has been in composition with finished product preparation form offer
Mixing, can also be provided with unit dose form, directly be mixed in proportion in bucket or tank using preceding, dense required for being then diluted to
Degree.
Further, composition pesticide of the invention can also add other agricultural active compositions, such as bactericide, desinsection
The agricultural active composition such as agent, herbicide, fertilizer.
Compared with prior art, composition pesticide of the invention has the beneficial effect that：
1st, in composition pesticide of the invention, active component benzothiostrobin and prothioconazoles are in certain scope to various crop
The preventing and treating of disease shows obvious synergistic function.
2nd, active component benzothiostrobin and the prothioconazoles mechanism of action are different in composition pesticide of the invention, both
Compounding use can delay the drug-fast generation of pathogen.
3rd, composition pesticide of the invention is using composition is low, prevention effect is good, to crop safety.
