3In the disclosure text, the physicochemical property of above-claimed cpd and the above-claimed cpd control efficiency to rice blast has been described also.In addition, the disclosure textual description above-claimed cpd good to the result of treatment of rice blast and residual activity and preventive effect, these effects are different from the result of treatment of conventional rice blast control agent.
The mechanism of action of the compound of formula (1) expression is not illustrated as yet fully.But, expect that these compounds have the mechanism of action that is different from conventional rice blast control agent, for example also can show control efficiency because of other resistant strain to kasugarnycin, organophosphorus reagent and strobilurins compound, show bactericidal activity in addition, and can not suppress melanic biosynthesis in the medium.
It is reported that the strobilurins Fungicidal compounds has good control efficiency or high bactericidal activity for the many rice fungus diseases that comprise rice blast or multiple mycosis or pathogen (it is as the fungi of these diseases that cause barley and wheat, fruit and vegetables main points of cultivation).The good control efficiency of strobilurins compound and the mechanism of action thereof for example are described in Noyaku Handobukku (agrochemistry handbook) 2001 (being published in calendar year 2001 by protection association of Japanese plant) and Ippan Itaku ShikenSeisekisho (general contrast experiment's report) (being published by protection association of Japanese plant).
Rice blast is severe diseases in the rice cropping.Rice blast is by the Pyricularia Sacc. fungi parasitogenic plant disease of (a kind of mould also belongs to Fungi Imperfecti).Up to the present, many good rice blast control agent and prevent and treat method have been reported.
Yet in some cases, even after using described control agent, also can specific meteorological condition (as abnormality cold summer gas and very long rainy season) and owing to the cause of disadvantageous cultivation condition (as the mismanagement to seedling and fertilising) breaks out rice blast.For those reasons, wish to develop the control agent that rice blast is had better control efficiency.In addition, the increase of the increase of recent part-time peasant's quantity and older's quantity of being engaged in agriculture has caused a kind of technology that can prolong the disease control time and reduce the application times and the amount of labour of needs development.In addition, from saving the angle of labour and the amount of application that reduces agricultural chemicals, wish to develop the chemical reagent that can show control efficiency simultaneously to multiple diseases.
Summary of the invention
By assessing the resultant effect of above-mentioned various active, these active duration etc., the inventor has now found that a kind of compound (2 that contains formula (1) expression, 3-dimethyl-6-the tert-butyl group-8-fluoro-4-8-hydroxyquinoline derivative) and at least a blend compositions that is selected from the strobilurins bactericide activity that can not lose each active component, have synergistic function simultaneously, and rice blast is shown excellent control efficiency.Also find in this connection when above-mentioned composition in due course machine use and when when time of application lags behind opportune moment, said composition can be the control efficiency that rice blast has excellence to a kind of representative disease of paddy rice with low dosage chronically.Finished the present invention based on this discovery.

Evaluation experimental
Experiment A: by before rice blast is propagated, using to the control efficiency of rice blast (when the suitable control
Experiment during machine)
Potted plant compost is put into the plastics cylinder, and (about 30cm * 50cm), (kind: Koshihikari) kind is gone in this cylinder, carries out intensive growing and cultivation then with the kind rice after the vernalization.This rice is used for experiment.
In glass greenhouse, cultivate about 2 weeks of this rice under 25 ℃ and night 20 ℃ of conditions by day.During the stage, ill leaf (this leaf has been inoculated Pyricularia oryzae (family 037) in advance and rice blast occurred) is placed on the rice of intensive plantation to three or four leaves when rice is long, under wet condition, places then with inoculation Pyricularia oryzae 24 hours.Then the rice strain is put back in the described glass greenhouse once more.After this 7 or 8 days, observe and scab occurred, carry out first time chemicals subsequently and use.In this case, (use the Neoesterin (trade name of 5000 times of dilutions with 10% aqueous acetone solution; By KUMIAICHEMICAL INDUSTRY CO., LTD. system) as being added into wherein spreader-sticker) will test with chemical liquid and be diluted to predetermined concentration.Amount with every cylinder 15ml is used each the experiment chemical liquid that makes thus by spray gun.When for the first time chemicals is used and is carried out after 6 or 7 days that the second time, chemicals was used, with the first time chemicals execute and carry out second time chemicals in a like fashion and use.
After this chemicals is used, in glass greenhouse, rice is controlled.During this period, with 1 to 2 day be the interval, place following 24 hours of wet condition to quicken the formation and the propagation of rice blast rice.
Last chemicals was used back ten days, to every cylinder 40 plant, observed the lesion area of the blade surface of a slice leaf position that is positioned at leaf below, the top, measured the percentage that lesion area accounts for treatment region.Measure the percentage that lesion area accounts for the district of being untreated in the mode identical in addition with treatment region.For every kind of experimental chemistry reagent, determine the protection value by the treatment region gained result and the district gained result that is untreated by following formula.
Protection value=[1-(the lesion area percentage in the lesion area percentage of the treatment region/district of being untreated)] * 100
Preventive effect and residual effect by following method determination experiment chemical reagent: whether after the predetermined number of days after wherein chemical reagent is handled, observing lesion area percentage increases.Thus, whether increase to determine preventive effect and residual effect according to last protection value.
Experimentize for each group of forming by the chemical reagent shown in the following table A1-A3.Carrying out once or twice chemicals uses.
The results are shown among the Table A 1-A3.

Experiment B: by after rice blast is propagated, using to the control efficiency (using the experiment that lags behind) of rice blast
Potted plant compost is put into the plastics cylinder, and (about 30cm * 50cm), (kind: Koshihikari) kind is gone in this cylinder, carries out intensive growing and cultivation then with the seed rice after the vernalization.This rice is used for experiment.
In glass greenhouse, cultivate about 2 weeks of this rice under 25 ℃ and night 20 ℃ of conditions by day.During the stage, ill leaf (this leaf has been inoculated Pyricularia oryzae (family 037) in advance and rice blast occurred) is placed on the rice of intensive plantation to three or four leaves when rice is long, under wet condition, places then with inoculation Pyricularia oryzae 24 hours.Then the rice strain is put back in the described glass greenhouse once more.After this 7 or 8 days, observe and scab occurs.Afterwards, place following 24 hours of wet condition infecting for the second time quickening once more rice, and in this cylinder, propagate rice blast.Quicken rice blast and propagate the back after about 3 or 4 days, confirm to have secondary scab seldom, carry out first time chemicals subsequently and use.
All the condition with experiment A is identical for other experiment conditions (as experiment chemical liquid condition, application process, administration interval, use rice blast development and the calculating of the method for preventing and treating, lesion area percentage and the calculating of protection value after the beginning).When carrying out that the second time, chemicals was used, its chemicals administration interval is identical with the interval of experiment A.
Test for every group that forms by the chemical reagent shown in the following table B1-B4 for each family.
