Description

DESCRIPTION
PLANT DISEASE CONTROL COMPOSITION AND METHOD FOR CONTROLLING PLANT DISEASE BY APPLICATION OF SAME
TECHNICAL FIELD
[0001] The present invention relates to a plant disease control composition, which is characterized by comprising as active ingredients thereof at least one quinoline compound represented by general formula (I) indicated below in the present description or a salt thereof (group a), and one or more fungicidal compound selected from the group consisting of compounds (b-1) to (b-106) (group b), and to a method for controlling plant disease by applying that composition.
BACKGROUND ART
[0002] Numerous chemical agents have conventionally been used to control plant diseases. However, the frequent use and over-administration of chemical agents having a similar structure and similar mode of action to control the same types of plant diseases has resulted in the significant problem of plant pathogens becoming resistant to these chemical agents.
[0003] On the other hand, there is currently a growing demand among consumers for agricultural products that are grown using reduced levels of agricultural chemicals as well as a social demand for a reduction in the burden that agricultural chemicals place on the environment.
[0004] In addition, in the case of treating agricultural crops by mixing two or more types of chemical agents by tank mixing at farm fields where chemical agents are actually used, the combining of incompatible chemical agents may cause a mutual reduction in the effects of the chemical agents or result in a considerable risk of causing phytotoxicity.
[0005] In consideration of such circumstances, there is a desire for a plant disease control composition that is highly effective against organisms that are resistant to existing chemical agents and exhibits higher efficacy using a smaller amount of active ingredient. Moreover, there is also a desire for a highly compatible plant disease control composition and method for controlling plant disease composed of components (compounds) having different basic structures and different modes of action in order to prevent plant pathogens from acquiring resistance.
[0006] A quinoline compound represented by general formula (I) is known to - -
demonstrate control effects as a fungicide against rice blast {Pyricularia oryzae) and against gray mold (Botrytis cinerea) in tomatoes, cucumbers and green beans by treating plants by seed disinfection or foliage spraying and the like (Patent Documents 1 to 4), while the mixing of a quinoline compound represented by general formula (I) with a certain type of fungicide is disclosed in Patent Document 5.

DISCLOSURE OF THE INVENTION
Problems to be Solved by the Invention
[0008] As a result of examining combinations of quinoline compounds represented by general formula (I) and other fungicidal components, the inventors of the present invention found that, by combining a quinoline compound represented by general formula (I) with a specific fungicidal compound, superior control effects (synergistic effects) are obtained against various plant pathogens that could not have been predicted from the individual components alone, stable preventive effects are demonstrated against organisms resistant to existing chemical agents, and the occurrence of chemical damage is not observed, thereby leading to completion of the present invention.
[0009] An object of the present invention is to provide a novel plant disease control composition, and method for controlling plant disease by applying that composition, that exhibits a plurality of disease spectra against various types of plant pathogens, demonstrates high plant disease control effects against organisms resistant to existing chemical agents, demonstrates a high level of activity even if the amount of active ingredient administered in a pathogen-rich environment is reduced, and is observed to be free of the occurrence of phytotoxicity.

[0034] The plant disease control composition of the present invention allows the obtaining of synergistic controlling effects in comparison with the case of using each of the active ingredients alone. The synergistic controlling effects and a degree thereof can be confirmed by using various test methods such as the method of Colby (see Colby SR, "Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weed, 15, 1967, 20-22). This is currently a most efficacious method to determine a combination effect of two agents, and as described below in detail, during a comparison of a theoretical value calculated by Colby's formula with an actual measured effect (actual value), it is judged to be synergistic when the actual value is greater than the theoretical value, whereas to be antagonistic when the actual value is greater than the theoretical value. In the case the difference between an actual value and a theoretical value is larger, the synergistic effect is presumed to be higher. Thus, as a preferable embodiment of the present invention, there is provided a plant disease control composition comprising a combination of effective ingredients that exhibit a difference between an actual value and a theoretical value, of 5% or more, more preferably 10% or more, and still more preferably 20% or more.
[0035] Although the plant disease control composition in the present invention may be used as is, it is normally used by mixing with a carrier, and is used by formulating into a wettable powder (WP), suspension concentrate (SC), granule (GR), dustable powder (DP), soluble concentrate (SC), water dispersible granule (WG), or emulsion concentrate (EC) and the like at a suitable time according to commonly known methods by adding a formulation additive such as a dispersing agent, wetting agent, binder, thickener, preservative, colorant or stabilizer and the like as necessary. Other types of formulations known in the art are also applicable in the present invention. As used herein, the name of preparation (formulation) types and codes are essentially based on OECD Guidance Documents for Pesticide Registration (http://www.oecd.org/env/ehs/pesticides-biocides/oecdguM
egistration.htm). The content of the active ingredient in the form of the quinoline compound (I: group a compound) in these preparations is normally a weight ratio within the range of 0.005% to 99%, preferably within the range of 0.1%) to 90% and even more preferably within the range of 0.3% to 80%. In addition, the content of the active ingredient in the form of the fungicidal compound of group b in these preparations is normally a weight ratio within the range of 0.005%) to 99%, preferably within the range of 0.1 % to 90% and even more preferably within the range of 0.3% to 80%. The total of the quinoline compound (I: group a compound) and the fungicidal compound of group b is normally a weight ratio within the range of 0.01% to 99%, preferably within the range of 0.1% to 90% and even more preferably within the range of 0.3% to 80%. The mixing ratio between the quinoline compound (I: group a compound) and the fungicidal compound of group b is normally a weight ratio of the fungicidal compound of group b to the quinoline compound 1 of 0.01 to 1000 and preferably a weight ratio of the fungicidal compound of group b to the quinoline compound 1 of 0.01 to 500, more preferably 1 of 0.01 to 100, still more preferably 1 of 0.01 to 50 and most preferably 1 of 0.01 to 25. Within this range, it would be easy to find a most preferable mixing ratio of actually combined individual compounds. It would also be possible to speculate a preferable mixing ratio of similar combinations in terms of a mode of action or chemical structure of the fungicidal compound of group b, based on the measured combinations having synergistic effects.
[0036] In the plant disease control composition of the present invention, although varying according to the preparation form, the combined content of active ingredients in the form of the quinoline compound (I: group a compound) and the fungicidal compound of group b is normally 0.01%) to 30% by weight in the case of a dustable powder, 0.1%) to 80%) by weight in the case of a wettable powder, 0.5% to 20%) by weight in the case of a granule, 2% to 50% by weight in the case of an emulsion concentrate, 1%) to 50% by weight in the case of a suspension concentrate, and 1% to 80% by weight in the case of a water dispersible granule. It is preferably 0.05 to 10% by weight in the dustable powder, 5 to 60% by weight in the wettable powder, 5 to 20%) by weight in the emulsion concentrate, 5 to 50% by weight in the suspension concentrate, and 5 to 50% by weight in the water dispersible granule. The content of additives is 0% to 80%) by weight, and the content of the carrier is the amount obtained by subtracting the total content of active ingredient compounds and additives from 100% by weight.

[0065] Test Example 1 Tomato Gray Mold Preventive Test
Tomato plants (variety: Ohgata Fukuju) planted in plastic pots having a diameter of 5 cm were grown indoors to the second to third leaf stage. Wettable powder prepared in compliance with Preparation Example 1 and Comparative Preparation Example 1 containing the compounds indicated in Table 2 were diluted with water to a prescribed concentration followed by spraying with a sprayer in 5 ml aliquots per 2 pots. After the chemical had dried, a conidia suspension of Botrytis cinerea which prepared from previously cultured in PDA medium was inoculated by spraying onto the plants. Following inoculation, the pots were placed in the humidified chamber of an artificial inoculation room (25 °C) and after 2 days, the pots were taken out and controlling effects were examined. During the examination, the percentage of affected area exhibiting lesions on a single tomato leaf was determined in accordance with the following incidence degree indicators. In addition, control values were calculated according to the equation indicated below from the average incidence degree of each treated group. The spray test results and theoretical values as determined according to Colby's formula are shown in Table 2.
[0066] Incidence Degree Indicators
Indicator Incidence Degree
0 No lesions
0.5 Lesion area of about 1% to 2%
1 Lesion area of less than 5%
2 Lesion area of less than 25%
3 Lesion area of less than 50%
4 Lesion area of less than 75%
5 Lesion area of less than 95%
6 Lesion area of 95% or more or withered
Furthermore, the average values of each treated group and an untreated group were used for incidence degree.
[0067] Control values were calculated from the equation indicated below.
Control value = (1 - leaflet incidence rate of treated
group/leaflet incidence rate of untreated group) x 100
Furthermore, synergistic effects were evaluated using Colby's formula.
Colby's formula is expressed as X = P + Q - P x Q/100, where X represents the theoretical value of the control value, P represents the control value in the case of spraying a certain chemical agent alone, and Q represents the control value in the case of spraying the chemical agent used in combination alone. In the case the actual measured effect is greater than the effect X as calculated with the aforementioned Colby's formula, the action resulting from combining two types of active ingredients is indicated to be more than additive, that is, to be synergistic.

[0081] Test Example 2 Rice Blast Preventive Test
Rice plants (variety: Sachikaze) planted in plastic pots having a diameter of 5 cm were grown indoors to the third to fourth leaf stage. Wettable powder containing the compounds indicated in Table 3 were sprayed in the same manner as in Test Example 1 , and after the chemical had dried, a conidia suspension of prepared from Pyricularia oryzae which had been previously cultured in oatmeal medium was inoculated by spraying onto the plants. Following inoculation, the pots were placed in the humidified chamber of an artificial inoculation room (20°C to 23 °C), and taken out on the next day and then transferred to a greenhouse. Control effects were examined 7 days after inoculation. During the examination, the number of lesions on the rice per pot was determined in accordance with the following incidence degree indicators, and control values and theoretical values as determined according to Colby's formula were calculated in the same manner as in Test Example 1. The results are shown in Tables

[0117] Test example 7 Cucumber downy mildew preventive test
In a greenhouse, cucumber (variety: Sagamihanshiro) planted in a plastic pot having a diameter of 5 cm was grown to the 3rd to 5th-leaf stage. Spray was carried out in the same manner as in Test example 1 , and after drying the chemical liquid, the pots were transferred into a greenhouse. After 3 days from the spray, a zoosporangium suspension of Pseudoperonospora cubensis was inoculated. After inoculation, the pots were placed in a high-humidity chamber (20 to 25 °C), transferred into a greenhouse on the next day, and controlling effects were examined after 7 days from the inoculation. A ratio of lesion area occupied per one leaf of cucumber was determined according to the same index as in Test example 1, and the control value and the theoretical value according to Colby's formula were similarly calculated.
