Description

Pest control composition and method for controlling plant diseases or plant pests using the composition

[0001] The present invention relates to a novel pest control composition and a method for controlling plant diseases or plant pests using the composition. This application claims priority to Japanese Patent Application No. 2023-212367, filed December 15, 2023, the contents of which are incorporated herein by reference.

[0002] In agricultural and horticultural fields, it has been common to use compositions suitable for controlling pests, such as insect pests, pathogens, and weeds. Furthermore, mixed compositions containing multiple active ingredients have been used for the purpose of simultaneously controlling various pests. Furthermore, for reasons such as reducing the user's workload, there are cases in which multiple-ingredient pesticides are simultaneously applied, such as by applying a pesticide (mixture) containing two or more active ingredients or by mixing several pesticides by tank mixing in a farm field.

[0003] On the other hand, with the use of chemicals over many years, resistant pests have emerged, making it increasingly difficult to control them with conventional chemicals. For this reason, there is a constant need for new pest control agents. In addition, in order to reduce the risk of the emergence of resistant pests, mixtures of active ingredients with different actions have been used (see, for example, Patent Documents 1 to 3).

[5] The pest control composition according to any one of [1] to [4], wherein the pest is at least one pest belonging to an order selected from the group consisting of Lepidoptera, Acaridae, Hemiptera, and Thripida. [6] The pest control composition according to any one of [1] to [4], wherein the pest is at least one pest belonging to a family selected from the group consisting of Noctuidae, Aphididae, Tetranychidae, and Thripidae. [7] The pest control composition according to any one of [1] to [4], wherein the pest is at least one pest selected from the group consisting of Spodoptera litura, Aphididae, Two-spotted Spider mite, and Thrips palmi. [8] The pest control composition according to [1], wherein the compound selected from at least one of the phenylpyrazole compounds, the isoxazoline compounds, and the metadiamide compounds is an isoxazoline compound, the isoxazoline compound is fluxametamide, and the pest is at least one kind of pest belonging to an order selected from the group consisting of Lepidoptera, Acarina, and Thripida.[9] A method for controlling plant diseases or plant pests, comprising applying the pest control composition according to any one of [1] to [8] to plants, seeds, or soil.

Which pest control composition is applied first is also not particularly limited as long as it is effective in controlling plant diseases or plant pests, but can be appropriately selected and determined depending on the target plant pests, plants, and other application environments.

[0033] The contents of the first and second components in the pest control composition of this embodiment are not particularly limited as long as the effect is exhibited. Two or more components can be used in combination as the second component. The mixing ratio of the first and second components is not particularly limited as long as the effect is exhibited. However, the mixing ratio (mass ratio) of the first component to the second component is preferably 1 / 300 to 300 / 1, more preferably 1 / 150 to 150 / 1, and even more preferably 1 / 50 to 50 / 1.

[0034] For example, when the pest is cotton aphid, the first component is spirotetramat, and the second component is brofuranilide, the mixing ratio (mass ratio) of spirotetramat to brofuranilide may be, for example, spirotetramat / brofuranilide = 1 / 3 to 50 / 1, for example, 1 / 2 to 30 / 1, or for example, 1 / 1 to 15 / 1. Alternatively, the concentration of spirotetramat may be 0.336 ppm or more, and the concentration of brofuranilide may be 0.075 ppm or more.

[0035] For example, when the pest is a cotton aphid, the first component is spirotetramat, and the second component is fluxametamide, the mixing ratio (mass ratio) of spirotetramat to fluxametamide may be, for example, spirotetramat / fluxametamide = 1 / 15 to 8 / 1, for example, 1 / 10 to 4 / 1, or for example, 1 / 5 to 2 / 1. Alternatively, the concentration of spirotetramat may be 0.336 ppm or more, and the concentration of fluxametamide may be 1.5 ppm or more.

[0036] For example, when the pest is a cotton aphid, the first component is spirotetramat, and the second component is isocycloceram, the mixing ratio (mass ratio) of spirotetramat to isocycloceram may be, for example, spirotetramat / isocycloceram = 1 / 20 to 6 / 1, for example, 1 / 10 to 3 / 1, or for example, 1 / 5 to 2 / 1. Alternatively, the concentration of spirotetramat may be 1.12 ppm or more, and the concentration of isocycloceram may be 0.6 ppm or more.

[0037] For example, when the pest is cotton aphid, the first component is spirotetramat, and the second component is ciprofuranilide, the mixing ratio (mass ratio) of spirotetramat to ciprofuranilide may be, for example, spirotetramat / ciprofuranilide = 1 / 8 to 50 / 1, for example, 1 / 4 to 25 / 1, or for example, 1 / 2 to 15 / 1. Alternatively, the concentration of spirotetramat may be 0.336 ppm or more, and the concentration of ciprofuranilide may be 0.075 ppm or more.

[0038] For example, when the pest is common cutworm, the first component is spirotetramat, and the second component is brofuranilide, the mixing ratio (mass ratio) of spirotetramat to brofuranilide may be, for example, spirotetramat / brofuranilide = 1 / 8 to 150 / 1, for example, 1 / 4 to 80 / 1, or for example, 1 / 2 to 40 / 1. Alternatively, the concentration of spirotetramat may be 0.0336 ppm or more, and the concentration of brofuranilide may be 0.0075 ppm or more.

[0039] For example, when the pest is common cutworm, the first component is spirotetramat, and the second component is ciprofuranilide, the mixing ratio (mass ratio) of spirotetramat to ciprofuranilide may be, for example, spirotetramat / ciprofuranilide = 2 / 1 to 150 / 1, for example, 2 / 1 to 80 / 1, or for example, 2 / 1 to 40 / 1. Alternatively, the concentration of spirotetramat may be 0.0336 ppm or more, and the concentration of ciprofuranilide may be 0.025 ppm or more.

[0040] For example, when the pest is common cutworm, the first component is spirotetramat, and the second component is fluxametamide, the mixing ratio (mass ratio) of spirotetramat to fluxametamide may be, for example, spirotetramat / fluxametamide = 5 / 1 to 25 / 1, for example, 5 / 1 to 20 / 1, or for example, 5 / 1 to 10 / 1. Alternatively, the concentration of spirotetramat may be 0.00336 ppm or more, and the concentration of fluxametamide may be 0.015 ppm or more.

[0041] For example, when the pest is common cutworm, the first component is spirotetramat, and the second component is isocycloceram, the mixing ratio (mass ratio) of spirotetramat to isocycloceram may be, for example, spirotetramat / isocycloceram = 1 / 40 to 280 / 1, for example, 1 / 20 to 140 / 1, or for example, 1 / 10 to 70 / 1. Alternatively, the concentration of spirotetramat may be 1.12 ppm or more, and the concentration of isocycloceram may be 0.4 ppm or more.

[0042] For example, when the pest is twospotted spider mite, the first component is spirotetramat, and the second component is brofuranilide, the mixing ratio (mass ratio) of spirotetramat to brofuranilide may be, for example, spirotetramat / brofuranilide = 2 / 1 to 20 / 1, for example, 4 / 1 to 16 / 1, or for example, 8 / 1 to 12 / 1. Alternatively, the concentration of spirotetramat may be 0.336 ppm or more, and the concentration of brofuranilide may be 0.025 ppm or more.

[0043] For example, when the pest is twospotted spider mite, the first component is spirotetramat, and the second component is isocycloceram, the mixing ratio (mass ratio) of spirotetramat to isocycloceram may be, for example, spirotetramat / isocycloceram = 1 / 20 to 4 / 1, or may be, for example, 1 / 10 to 2 / 1, or may be, for example, 1 / 5 to 2 / 1. Alternatively, the concentration of spirotetramat may be 0.00336 ppm or more, and the concentration of isocycloceram may be 0.006 ppm or more.

[0044] For example, when the pest is twospotted spider mite, the first component is spirotetramat, and the second component is fluxametamide, the mixing ratio (mass ratio) of spirotetramat to fluxametamide may be, for example, spirotetramat / fluxametamide = 1 / 50 to 5 / 1, for example, 1 / 5 to 1 / 1, or for example, 1 / 100 to 1 / 4. Alternatively, the concentration of spirotetramat may be 0.00336 ppm or more, and the concentration of fluxametamide may be 0.5 ppm or more.

[0045] For example, when the pest is two-spotted spider mite, the first component is spirotetramat, and the second component is ciprofuranilide, the mixing ratio (mass ratio) of spirotetramat to ciprofuranilide may be, for example, spirotetramat / ciprofuranilide = 5 / 1 to 15 / 1, for example, 5 / 1 to 10 / 1, or for example, 5 / 1 to 7 / 1. Alternatively, the concentration of spirotetramat may be 0.336 ppm or more, and the concentration of ciprofuranilide may be 0.025 ppm or more.

[0046] For example, when the pest is the diamondback moth, the first component is spirotetramat, and the second component is brofuranilide, the mixing ratio (mass ratio) of spirotetramat to brofuranilide may be, for example, spirotetramat / brofuranilide = 1 / 1 to 15 / 1, for example, 1 / 1 to 10 / 1, or for example, 1 / 1 to 7 / 1. Alternatively, the concentration of spirotetramat may be 0.0112 ppm or more, and the concentration of brofuranilide may be 0.0075 ppm or more.

[0047] For example, when the pest is the diamondback moth, the first component is spirotetramat, and the second component is ciprofuranilide, the mixing ratio (mass ratio) of spirotetramat to ciprofuranilide may be, for example, spirotetramat / ciprofuranilide = 1 / 3 to 5 / 1, for example, 1 / 2 to 4 / 1, or for example, 1 / 2 to 3 / 1. Alternatively, the concentration of spirotetramat may be 0.0112 ppm or more, and the concentration of ciprofuranilide may be 0.0075 ppm or more.

[0050] Sample Preparation and Test Methods (1) Sample Preparation and Test Methods for Evaluating Cotton Aphids A 1% agar solution was prepared and poured into a glass tube bottle with a diameter of 40 mm and a depth of 60 mm to 80% and allowed to solidify at room temperature. A small amount of 1% agar was then added as an adhesive, and a cucumber leaf with a diameter of 35 mm was placed face down on top. Approximately seven adult cotton aphids were released, and the glass tube was placed upside down on a grid and left in a thermostatic chamber at 25°C. After 24 hours, the adults were removed, and the first-instar larvae were counted.

[0051] The test agent was prepared to a predetermined concentration using a 0.01% Gramin S solution. 7 ml of the test agent was sprayed onto the counted glass tube bottles using a rotary spray tower and air-dried. The bottles were then left in a thermostatic chamber at 25°C, and after a predetermined number of days, the number of live and dead insects attached to the leaves and on the grid was counted, and the mortality rate (%) ((number of dead insects / number of test insects) * 100) was calculated.

[0052] (2) Sample preparation and test method for evaluation of Spodoptera litura The test agent was prepared to a predetermined concentration using a 0.03% Gramin S solution. The test solution was transferred to a cup, and cabbage leaves were placed in it and immersed for 15 seconds. After air drying, the leaves were transferred to another cup, and third-instar Spodoptera litura larvae were released into the cup. The test samples were left in a thermostatic chamber at 25°C, and after a predetermined number of days, the number of live insects and dead insects were counted, and the mortality rate (%) ((number of dead insects / number of test insects) * 100) was calculated.

[0053] (3) Sample preparation and test method for evaluation of diamondback moth The test agent was prepared to a predetermined concentration using a 0.03% Gramin S solution. The test solution was transferred to a cup, and cabbage leaves were placed in it and immersed for 15 seconds. After air drying, the leaves were transferred to another cup, and third-instar diamondback moth larvae were released into it. The samples were left in a thermostatic chamber at 25°C, and after a predetermined number of days, the number of live insects and dead insects were counted, and the mortality rate % ((number of dead insects / number of test insects) * 100) was calculated.

[0054] (4) Sample preparation and test method for evaluation of two-spotted spider mites A 9 cm petri dish was lined with absorbent cotton and water was poured up to the top of the cotton. Two kidney bean leaves cut into 2 cm x 4 cm pieces were placed on top of the dish with a gap between them, with the underside facing up. Four to five adult female two-spotted spider mites were released and left in a thermostatic chamber at 25°C for 24 hours. The adult females were then removed and the number of eggs laid was counted.

[0055] The test agent was prepared to a predetermined concentration using a 0.01% Gramin S solution. The counted green bean leaf discs were sprayed with 7 ml of the test agent using a rotary spray tower, air-dried, and then left in a thermostatic chamber at 25°C. After a predetermined number of days, the number of unhatched eggs, live insects, dead insects, and insects that had escaped from the leaves were counted under a microscope, and the sum of the egg killing rate % ((unhatched eggs / number of test eggs) * 100) + insect mortality rate % (((number of dead insects + number of escaped insects) / number of test eggs) * 100) was calculated.

[0056] (5) Sample preparation and test method for evaluating Bemisia tabaci (biotype Q) A 1% agar solution was prepared and poured into a glass tube bottle with a diameter of 40 mm and a depth of 60 mm to 80% and allowed to solidify at room temperature. A small amount of 1% agar was then added as an adhesive, and a 35 mm diameter cabbage leaf was placed face down on top. Approximately 10 adult Bemisia tabaci were released, and the glass tube was placed upside down on a grid and left in a thermostatic chamber at 25°C. After 72 hours, the adults were removed, and after leaving it for another week, the number of hatched first-instar larvae was counted. Unhatched eggs were removed with tweezers.

[0057] The test agent was prepared to a predetermined concentration using a 0.03% Gramin S solution. 7 ml of the test agent was sprayed onto the counted glass tube bottles using a rotary spray tower and air-dried. The bottles were then left in a thermostatic chamber at 25°C, and after a predetermined number of days, the number of live and dead insects parasitizing the leaves was counted, and the mortality rate (% [(dead insects / number of test insects) * 100]) was calculated.

[0058] Example 1 A pest control composition containing spirotetramat as a first component and broflanilide as a second component was prepared. The pest control composition was used against first-instar larvae of cotton aphid, a pest belonging to the order Hemiptera and family Aphididae, by spraying the composition on cucumbers, leaf discs, and insect bodies. The results obtained 1 day, 2 days, and 3 days after treatment are shown in Tables 1 to 7.

[0063] Based on the mortality rates at each predetermined concentration shown in Tables 1 and 2, the predicted mortality rate for each concentration combination can be calculated using the Colby formula shown in formula (F1) below: E = X + Y - XY / 100 ... (F1) In formula (F1), X represents the observed value (mortality rate) of agent A at concentration x, Y represents the observed value (mortality rate) of agent B at concentration y, and E represents the mortality rate expected when agents A and B are mixed.

[0064] The results are analyzed as follows: if the observed value is greater than the predicted value, it indicates a synergistic effect; if the predicted value is greater than the observed value, it indicates an antagonistic effect; and if the observed value and predicted value are the same, it indicates an additive effect.

In Table 84, the values ​​in parentheses indicate the mortality rates predicted by the Colby formula. As a result, six days after treatment, the mortality rates were 47.0% and 91.6%, respectively. This result indicated a synergistic effect compared to the mortality rates predicted by the Colby formula (16.1% and 62.7%, respectively).

[0258]

[0259] Table 85 below shows the mortality rates of insects when spirotetramat 0.336 ppm and ciproflanilide 0.0075 and 0.025 ppm were used in combination. In Table 85, the values ​​in parentheses indicate the mortality rates predicted by the Colby formula. As a result, six days after treatment, the mortality rates were 17.3% and 73.9%, respectively. This result indicated a synergistic effect compared to the mortality rates predicted by the Colby formula (12.1% and 61.0%, respectively).

[0260]

[0261] For comparison, spiromesifen was used instead of spirotetramat to prepare a pest control composition containing spiromesifen and broflanilide. The pest control composition was used in a cabbage leaf immersion test against third-instar larvae of the diamondback moth, a pest belonging to the Lepidoptera, Noctuidae family. The results three days after treatment are shown in Table 86.

[0262]

[0263] Based on the mortality rates at each predetermined concentration shown in Tables 75 and 86, the predicted mortality rates for each concentration combination can be calculated using the Colby formula described above.

[0264]

[0265] The combined use of spiromesifen at 0.15 ppm and brofuranilide at 0.025 ppm resulted in a mortality rate of 75% three days after treatment. This result indicated no synergistic effect compared to the mortality rate (80% three days after treatment) predicted from the mortality rate of spiromesifen at 0.15 ppm alone (0.0% three days after treatment) and the mortality rate of brofuranilide at 0.025 ppm alone (80% three days after treatment).

[0266] Example 15 A pest control composition containing spirotetramat as a first component and broflanilide as a second component was prepared. The pest control composition was used against first-instar larvae of Bemisia tabaci, a pest belonging to the Hemiptera and Aleyrodidae families, by applying it to cabbage, leaf discs, and the insect bodies. The results 7 days after treatment are shown in Tables 88 to 92.

[0267] Table 88 below shows the mortality rate when spirotetramat was used alone.

[0268]

[0269] Table 89 below shows the mortality rate when broflanilide was used alone.

[0270]

[0271] Based on the mortality rates at each predetermined concentration shown in Tables 88 and 89, the predicted mortality rates for each concentration combination can be calculated using the Colby formula described above.

[0272] Table 90 below shows the mortality rates for the combined use of spirotetramat at 0.336 ppm and broflanilide at 0.025, 0.075, 0.25, 0.75, and 2.5 ppm. In Table 90, the values ​​in parentheses indicate the mortality rates predicted by the Colby formula. Seven days after treatment, the mortality rates were 32.9, 31.8, 44.9, 27.6, and 31.4%, respectively. These results indicated a synergistic effect compared to the mortality rates predicted by the Colby formula (18.6, 27.5, 18.6, 18.6, and 18.6%, respectively).

[0273]

[0274] Table 91 below shows the mortality rates for the combined use of spirotetramat at 1.12 ppm and broflanilide at 0.025, 0.075, 0.25, 0.75, and 2.5 ppm. In Table 91, the values ​​in parentheses indicate the mortality rates predicted by the Colby formula. As a result, seven days after treatment, the mortality rates were 28.6, 26.6, 37.5, 21.2, and 23.0%, respectively. These results indicated a synergistic effect compared to the mortality rates predicted by the Colby formula (15.5, 24.7, 15.5, 15.5, and 15.5%, respectively).

[0275]

[0276] Table 92 below shows the insect mortality rates resulting from the combined use of spirotetramat at 3.36 ppm and broflanilide at 0.025, 0.075, 0.25, 0.75, and 2.5 ppm. In Table 92, the values ​​in parentheses indicate the insect mortality rates predicted by the Colby formula. As a result, seven days after treatment, the insect mortality rates were 65.6, 73.9, 66.4, 85.7, and 76.2%, respectively. These results indicated a synergistic effect compared to the insect mortality rates predicted by the Colby formula (52.7, 57.9, 52.7, 52.7, and 52.7%, respectively).
