Description

Mating behavior disruptor for sucking pests

The present invention relates to a copulation disruption agent for sucking pests.

N-cyanomethyl-4-trifluoromethyl-3-pyridinecarboxamide (generic name flonicamid) is a compound described as Patent No. 1 in Patent Document 1. Patent Document 2 describes a pesticidal composition containing a pyridine-based compound containing flonicamid and various efficacy enhancing components.

European Patent Publication No. 580374 International Publication Gazette WO 2009/128409

Root beetles, which are sucking pests that are regarded as the main pests in the field of rice cultivation, have a high growth potential and cause enormous damage to rice. In particular, the brown planthopper repeatedly grows over a number of generations until the harvest season, and the main damage is caused by the dryness of rice. “Tsubo withering” refers to the damage that rice dies and / or surrenders due to the sucking damage of the brown planthopper. At present, neonicotinoid insecticides are the mainstream as a control agent for planthoppers, but recently, planthoppers with reduced susceptibility to neonicotinoid insecticides have been seen. In the field of rice cultivation, there is a demand for a control agent or control method that can replace neonicotinoid insecticides and become a new mainstream.

The ecology of the green planthopper is characteristic, and the present inventors conducted research in connection with the characteristic ecology in the control of planthoppers including the green planthopper.
Tobiro planta cannot overwinter in areas north of Vietnam. For example, in Japan, the long-winged adult worms that fly from the lower part of the jet stream from overseas during the rainy season from late June to July are the source. The flying density is considerably lower than that of the overseas flying white smelt, and the parasitic density at the time of flying does not cause a big problem.
However, after flight, adult females lay eggs in the tissue of rice leaf sheaths after a pre-laying period of about 4 days, and at 25 ° C, the next generation (first generation) adults after an egg period of 7-9 days and a larval period of 14 days. It becomes. First-generation female adults often have short wings with a high growth rate. Short-cage females do not move much and have a large number of eggs, so the second generation population is locally and geometrically dense, and witheres at the time of the second or third generation. cause.
In Southeast Asian countries in the sub-Vietnam where the brown planthopper can winter, the same damage as described above is caused by local growth and withering.
Furthermore, at present, no pesticide has been found that is effective against brown planthopper eggs and has safety to the environment and beneficial insects.
From such things, the present inventors, in order to find a method to prevent the damage of the brown planthopper, do not spawn adult adults and first generation adults, make it difficult to spawn and prevent eggs from hatching, etc. We focused on reducing the next generation population and density of pests.

As a result, the present inventors have found that flonicamid, among various active ingredients of agricultural chemicals, has the effect of disturbing the copulation behavior of sucking pests, which solves the above problems, and completed the present invention. The copulation behavior disturbing action in the present invention refers to an action of suppressing a series of mating actions in which a female searches for a female by suppressing the action of calling the male by vibration of the abdomen. As a result of disturbing the mating behavior in this way, the number of female laying eggs decreases, and furthermore, the eggs laid are not hatched because they are unfertilized eggs.
That is, the present invention relates to a method for controlling sucking pests by causing flonicamid to act on sucking pests, a method for reducing the next generation population of sucking pests, and a method for disturbing the mating behavior of sucking pests.

The mating behavior disrupting agent and control method for sucking pests according to the present invention can exhibit a stable and high control effect over a long period of time.
In addition, the present invention is completely different from the use of flonicamid as a simple pesticide, and has an unexpected effect of reducing the next-generation population of pests. For example, when a seedling box treatment is performed, a conventionally used control agent cannot be expected to have a long-lasting residual effect, and therefore it is necessary to treat the spray agent a plurality of times. It is possible to reduce the number of times of agent treatment. Applying the completely unexpected effect of “reducing the next generation of pests” disclosed by the present invention, for example, when applied to a seedling box treatment, it is usually desired to control sucking pests over a sufficiently long period of time. The effect is demonstrated.

It is a graph which shows the result of the next generation population suppression effect at the time of conducting the adult flying planthopper release test by the seedling box processing of flonicamid granule. It is a graph which shows the result of the next generation population suppression effect at the time of conducting the adult planthopper release test by the seedling box process of the granule for flonicamid seedling box process.

The active ingredient for agricultural chemicals in the present invention is flonicamid. Flonicamid is a common name and its chemical name is N-cyanomethyl-4-trifluoromethyl-3-pyridinecarboxamide. Flonicamid may form a salt.

In the present invention, examples of the rice parasitic sucking insects include planthoppers, leafhoppers, and stink bugs.
The planthoppers include brown planthoppers, white-spotted planthoppers, and leafhoppers. The leafhoppers include leafhopper leafhoppers and the like, and the stink bugs include akazikakasomika and akahigehosomidorikamikameka.
In the present invention, the soup pests preferably include planthoppers and leafhoppers. More preferably, a planthopper is mentioned.
More preferred is a brown planthopper.
Examples of the sucking pests to be controlled according to the present invention include sucking pests having reduced sensitivity to neonicotinoid insecticides.

In the present invention, flonicamid is selected from the group consisting of nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, animal and vegetable oils, mineral oils, water-soluble polymers, resins and waxes. In addition, at least one efficacy enhancing component can be used in combination.

In the present invention, flonicamid can be formulated in various forms such as emulsions, powders, wettable powders, liquids, granules, suspensions and the like by blending with various adjuvants as in the case of conventional agricultural chemical preparations. . Examples of the auxiliary agent include a carrier, a suspending agent, a thickening agent, a stabilizer, a dispersing agent, a wetting agent, a penetrating agent, an antifreezing agent, an antifoaming agent, and the like. Carriers are divided into solid carriers and liquid carriers, and solid carriers include starch, sugar, cellulose powder, cyclodextrin, activated carbon, soybean powder, wheat flour, rice bran powder, wood powder, fish powder, milk powder, and other animal and vegetable powders. Talc, kaolin, bentonite, organic bentonite, calcium carbonate, calcium sulfate, sodium bicarbonate, zeolite, diatomaceous earth, white carbon, clay, alumina, silica, sulfur powder, mineral powder such as slaked lime, etc., liquid carrier As: water; alcohols such as ethyl alcohol and ethylene glycol; ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, and isophorone; ethers such as dioxane and tetrahydrofuran; and aliphatic hydrocarbons such as kerosene, kerosene, and liquid paraffin Toluene, xylene, tri Aromatic hydrocarbons such as tilbenzene, tetramethylbenzene, cyclohexane and solvent naphtha; Halogenated hydrocarbons such as chloroform and chlorobenzene; Acid amides such as N, N-dimethylformamide; Acetic acid ethyl ester, fatty acid glycerin ester, etc. And nitriles such as acetonitrile; sulfur-containing compounds such as dimethyl sulfoxide; N-methyl-2-pyrrolidone and the like. Examples of the dispersant include polycarboxylic acid or a salt thereof, lignin sulfonic acid or a salt thereof, and the like. When using the efficacy enhancing component, flonicamid and the efficacy enhancing component may be mixed and formulated together, or separately formulated and mixed. In actual use of these preparations, they can be used as they are or after diluting to a predetermined concentration with a diluent such as water.

In the present invention, flonicamid can be treated in a nursery box or treated in a paddy field. In the method of the present invention, a seedling box treatment is desirable because a particularly significant effect can be achieved by sucking the soup pest. This is because flonicamid which is an active ingredient of agricultural chemicals having high water solubility can be efficiently taken into the plant body by the action of sucking up the drug from the root of rice by the seedling box treatment.

In the present invention, flonicamid can be formulated into various forms as described above, but from the viewpoint that the seedling box treatment is desirable, it is desirable to use a granule for the seedling box treatment.
As a granule for treatment of a seedling box suitable for exerting the effects of the present invention, a composition containing flonicamid and a poorly water-soluble resin is used. In the preparation, flonicamid and the poorly water-soluble resin are difficult to form a matrix, that is, flonicamid is difficult. The composition characterized by forming the composition taken in by water-soluble resin is mentioned, It mentions in full detail below.

The active ingredient flonicamid used in the present invention is known to be a compound having a very high water solubility (water solubility at 20 ° C .: 5200 mg / L). Since chemicals for nursery box treatment need to maintain their efficacy over a long period of time, it is required to control the elution of active ingredients of agricultural chemicals, while a compound with extremely high water solubility such as flonicamid is applied to this usage mode. It has been difficult to do. The composition is an effective embodiment for solving the problems caused by the aqueous solubility of flonicamid. The blending amount is 0.1 to 30% by weight, preferably 0.5 to 25% by weight.
The average particle size of flonicamid used in the present invention is 1 to 500 μm, preferably 1 to 100 μm, and more preferably 5 to 50 μm.
As the poorly water-soluble resin that can be used in the present invention, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / veova copolymer, styrene / acrylic acid copolymer, acrylic ester, Acrylic / silicone copolymer, polyethylene oxide, urethane resin, petroleum resin and the like can be mentioned. The poorly water-soluble resin is desirably used as an emulsion, and in particular, an ethylene / acrylic acid copolymer emulsion is desirable. Examples of the ethylene / acrylic acid copolymer emulsion include HYTEC S-3111, HYTEC S-3121, and HYTEC S-3127 (manufactured by Toho Chemical Industry Co., Ltd.). These resin emulsions can be used alone or in combination. The blending amount is 0.1 to 30% by weight, preferably 1 to 15% by weight in terms of solid content.
The carrier used in the present invention is not particularly limited, and for example, a carrier such as clay, bentonite, talc, calcium carbonate, gericite, sericite, acid clay, diatomaceous earth, zeolite, perlite, attapulgite and the like can be used. . The blending amount is not particularly limited, but is in the range of 40 to 99.8% by weight, preferably 60 to 98.5% by weight.
Since the composition uses a poorly water-soluble resin, it does not fit well with water, and the drug may float after transplantation into Honda. Therefore, it is desirable to add a wetting agent. Examples of the wetting agent include sodium dioctyl sulfosuccinate, sodium alkylbenzene sulfonate, higher alcohol sulfate ester, sodium alkyl naphthalene sulfonate, polyoxyethylene phenyl ether sulfate, polyoxyethylene styryl phenyl ether sulfate, polyoxyethylene alkyl ether, and the like. Desirably, polyoxyethylene styryl phenyl ether sulfate is used. These wetting agents can be used alone or in combination. When a wetting agent is used, the blending amount is not particularly limited, but is 0.01 to 10% by weight, preferably 0.1 to 5% by weight.
The composition is a granulation method usually used in the production of agricultural chemicals, for example, extrusion granulation method, tumbling granulation method, tumbling fluidized granulation method, fluidized bed granulation method, compression granulation method, stirring and granulation method. It can be prepared by a granulation method, a coating granulation method, a tableting method or the like.
For example, after uniformly mixing flonicamid, a wetting agent and a carrier, adding a slightly water-soluble resin emulsion, kneading with a kneader, etc., granulating with an extrusion granulator such as Dome Gran, drying, and sizing You can get things.
In addition, an elution control agent such as paraffin can be added to the composition to further control the elution rate as desired.
In the composition, in addition to the components described above, as an optional component, for example, the purpose of stably maintaining the pesticidal active ingredient in the pesticidal formulation of the present invention and / or the purpose of improving the granulation property when granulating Thus, a surfactant, an auxiliary agent and the like can be contained as necessary.

In the present invention, if necessary, agrochemical components other than flonicamid, such as fungicides, insecticides, acaricides, nematicides, antiviral agents, attractants, herbicides, plant growth regulators, etc. Can be used in combination, and in this case, a more excellent effect may be exhibited. For example, it is possible to improve the application range, the timing of chemical treatment, the control activity, and the like in a preferable direction. Flonicamid and the other active ingredient compounds of other agricultural chemicals may be prepared separately and mixed at the time of spraying, or both may be used together. For example, when preparing the composition, it can be formulated together with flonicamid and other agrochemical ingredients. The present invention includes a case where the active ingredients are mixed and applied in this way.

Test Example 1 Control effect against brown planthopper by treatment with flonicamid seedling box 1.2 mg × 1.2 cm cell seedlings (3 / strain) at a ratio of 1.5 mg ai / strain, prepared according to Formulation Example 1 The agent was processed in a nursery box. One day after the flonicamid treatment, the rice was extracted from the cell together with the soil, transplanted one strain per pot, and the water depth was maintained at 3 cm. Two small greenhouses were prepared, and 24 pots for flonicamid treatment and no treatment were installed in each small greenhouse. Ten , 17 and 30 days after transplanting, 100 adults of Nilaparvata lugens / greenhouse were released. After the release, the number of adults per 24 rice lines and the number of newly born next-generation larvae that infested rice at regular intervals were measured. The results are shown in Table 1 and FIG. In FIG. 1, ◯-○ (circle) represents the number of adult larvae (head) in the flonicamid-treated group, and Δ-Δ (triangle mark) represents the number of adult larvae (head) in the untreated group.

In Table 1 and FIG. 1, from the transition of the number of untreated adult larvae, the 29th day after rice transplantation was the first generation peak, and the 57th day after rice transplantation was the second generation peak. It can be inferred that the number of adult larvae decreased on the 39th day after rice transplantation is the state before the eggs hatched by the first generation adults. In addition, the 3 adult release is assumed to be a situation where the brown planthopper flew from another area in an actual paddy field. Under this circumstance, the peak of the first generation was not observed in the flonicamid-treated group, and the number of second-generation adult larvae was greatly suppressed.

Test Example 2: Mating behavior disturbing action against a brown planthopper 10 seeds of rice were sown on 40 mm × 40 mm absorbent cotton to prepare a rice seedling having a height of about 5 cm. Rice seedlings were immersed in an aqueous solution containing 200 ppm of the active ingredient flonicamid, air-dried, and placed in a glass vial (inner diameter 40 mm × height 75 mm; capacity 50 ml). An adult non-mating leafhopper ( Nilaparvata lugens ) raised from the age of the old larvae was bred with drug-untreated rice seedlings. From the 6th day after emergence, the animals were bred on immersion-treated rice for 24 hours. On the 7th day after emergence, after 24 hours had passed after each male and female were put together on the soaked rice, the male was removed, and the female was then allowed to lay eggs until the 14th day of emergence. The number of next-generation larvae was measured by comparing the number of newly born next-generation larvae in immersion-treated rice seedlings (flonicamide treated group) and drug-untreated rice seedlings (untreated group). Moreover, when one male and one female were put together, they were observed for 2 hours to confirm the presence or absence of mating behavior.
In order to confirm that no next-generation larvae were generated in an unmated state, an unmated female was bred alone in an untreated group, and the number of next-generation larvae was measured (unmated group). The results are shown in Table 2.

Test Example 3: Mating behavior disruptive effect on a brown planthopper line that is less sensitive to neonicotinoid insecticides The testimony of the planthopper of Test Example 2 is less sensitive to the common name imidacloprid, a typical neonicotinoid insecticide The same test was conducted in place of the brown planthopper, and the number of next-generation larvae was measured in comparison with the flonicamid treated group and the untreated group. The results are shown in Table 3.

Test example 4: Disrupting effect of mating behavior on white- spotted plant The white- spotted planthopper in Test example 2 was replaced with a white- spotted planthopper ( Sogatella furcifera ), and the same test was conducted. Was measured. The results are shown in Table 4.

Test Example 5: Mating behavior disruption effect on Japanese brown planthopper The Japanese brown planthopper of Test Example 2 was replaced with Japanese brown planthopper ( Laodelphax striatella ), and the same test was carried out. The number of next-generation larvae compared with the flonicamid treated group and the untreated group Was measured. The results are shown in Table 5.

From the results of Test Examples 2 to 5, it can be seen that, in the present invention, copulation behavior disturbance is caused to various planthoppers and the number of next-generation individuals is suppressed. Moreover, it turns out that this invention shows the outstanding effect also to the brown planthopper which has fallen sensitivity to the imidacloprid conventionally used as the mainstream of the planthopper control agent.

Test Example 6: Disturbance of mating behavior against brown planthopper A rice seedling was tested according to Test Example 2 except that it was treated with an aqueous solution containing the active ingredients flonicamid 50, 12.5, 3.1 and 0.8 ppm. It was. Table 6 shows the results of measuring the number of generations of next-generation larvae in comparison with the flonicamid-treated group and the non-treated group.

Test Example 7 Mating Action Disturbing Action on White-Spotted Plant A rice seedling was tested according to Test Example 4 except that it was treated with an aqueous solution containing the active ingredients flonicamid 50, 12.5 and 3.1 ppm. Table 7 shows the results of measuring the number of generations of next-generation larvae in comparison with the flonicamid-treated group and the untreated group.

Test Example 8 Mating Behavior Disturbing Action for Brown Bean Spike A test was conducted according to Test Example 5 except that rice seedlings were treated with an aqueous solution containing the active ingredients flonicamid 50, 12.5, and 3.1 ppm. Table 8 shows the results of measuring the number of generations of next-generation larvae in comparison with the flonicamid-treated group and the non-treated group.

Test Example 9: Mating behavior disturbing action against a brown planthopper line that is less sensitive to neonicotinoid insecticides Tested according to Test Example 3 except that rice seedlings were treated with an aqueous solution containing 0.8 ppm of the active ingredient flonicamid Went. Table 9 shows the results of measuring the number of generations of next-generation larvae in comparison with the flonicamid-treated group and the non-treated group.

From the results of Test Examples 6 to 9, in the present invention, even when a low concentration of active ingredient such as 3.1 ppm is treated for various planthoppers, the mating behavior is disturbed and the number of next generation individuals is suppressed. I understand that. In addition, for the brown planthopper whose sensitivity to imidacloprid, which has been conventionally used as the mainstream of the planthopper control agent, even when a low concentration active ingredient such as 3.1 ppm is processed, It can be seen that the effect is excellent.

Test Example 10: Mating behavior disturbing action against leafhopper leafhopper The leafhopper of Experiment example 2 was replaced with leafhopper leafhopper ( Nephotettix cincticeps ), and the same test was conducted, and rice seedlings were treated with flonicamid treated with an aqueous solution containing the

active ingredient flonicamid

200, 50 ppm. The number of next-generation larvae was measured in comparison with the ward and the untreated ward. The results are shown in Table 10.

From the results of Test Example 10, it can be seen that the present invention suppresses the number of next-generation individuals against the leafhopper leafhopper in the present invention.

Test Example 11 Control effect against brown planthopper by treatment with flonicamid nursery box A pest control composition prepared according to Formulation Example 2 in a ratio of 6, 12, 24 and 36 g ai / box in a 30 cm × 60 cm nursery box Processed. Untreated zone and dinotefuran granule (trade name: Starkle box granule, manufactured by Mitsui Chemicals Agro) Treatment zone (24 g ai / box) and imidacloprid granule (trade name: Admeier box granule, manufactured by Bayer CropScience) A treatment zone (24 g ai / box) was installed. Flonicamide was treated on the day of transplantation, and transplanted to a field of 32 m ² in 1 ward by a rice planting machine. 36, 43, 51, 57, and 65 days after transplantation, 500 adults of brown planthopper and 12,000 eggs were released on 100 m ² of the field. The number of adults per 24 strains of rice and the number of newly born next-generation larvae infested with rice in

transplants

78, 89 and 96 were measured. The results are shown in Table 11. For reference, FIG. 2 shows a graph of the flonicamid-treated section as a representative example of the 24 g ai / 10a flonicamid-treated section. ●-● (black circle) represents the number of adult larvae (head) in the 24 g ai / 10a flonicamid-treated group, and □-□ (white square mark) represents the number of adult larvae in the imidacloprid granule-treated group (head). .DELTA .-. DELTA. (White triangles) represent the number of adult larvae (head) in the dinotefuran granule-treated group, and xx (x mark) represents the number of adult larvae (head) in the untreated group.

5 times of insect release were carried out in paddy fields in the southwestern warm districts when the brown planthopper flew from other areas. From the transition of the number of untreated adult larvae, the first generation (next generation) peak was on the 89th day after rice transplantation. In the control agent Starkle granule treatment group, the density of the formed larvae was suppressed until 70 days after transplantation after the start of the investigation, but thereafter it started to increase. Similarly, in the control agent Admeier box granule treatment group, the density of the formed larvae was suppressed until 70 days after the transplantation, which started the investigation. However, the density started to increase, and the first generation (next generation) peak occurred on the 89th day after the transplantation. Was observed. Under this circumstance, the peak of the first generation (next generation) was not observed in the flonicamid treatment group, and the number of formed larvae was significantly suppressed until 89 days after transplantation. This result shows that the present invention is particularly useful in the situation of controlling rice parasitic sap pests where there is a demand to suppress the increase in the number of insect pests as long as possible after the chemical treatment.

Test Example 12 Control effect against brown planthopper by treatment with flonicamid stalks and leaves The plant was transplanted to a field of 32 m ² in 1 ward by a rice planting machine. 36, 43, 51, 57, and 65 days after transplantation, 500 adults of brown planthopper and 12,000 eggs were released on 100 m ² of the field. 70 days after transplantation, flonicamid was treated with foliacamide at a heading period with a spraying amount of 150 L / 10a. An untreated zone, a pymetrozine wettable powder (trade name: Chess wettable powder, manufactured by Syngenta) treatment zone and a dinotefuran aqueous solvent (trade name: Starkle granule aqueous solvent, manufactured by Mitsui Chemicals Agro Co., Ltd.) treatment zone were installed. Immediately before treatment, the number of adult worms per 24 strains of rice and the number of newly born next-generation larvae infested with rice after 2, 8, 19, 26 and 33 days of treatment were measured. The results are shown in Table 12.

5 times of insect release were carried out in paddy fields in the southwestern warm districts when the brown planthopper flew from other areas. From the transition of the number of untreated adult larvae, the 19th day of treatment was the peak of the first generation (next generation). It can be inferred that the number of adult larvae decreased on the 26th day of treatment is the state before the eggs hatched by the first generation adults. Both the control agent, pymetrozine wettable powder and dinotefuran aqueous solvent treatment group showed a high density suppressing effect. Under this circumstance, the first generation (next generation) peak was not observed in the flonicamid-treated group, and the number of formed larvae was suppressed to the same level as the control agent until 2 to 3 weeks after the treatment.
