{COPULATION DISRUPTION AGENT FOR SAP-SUCKING PESTS}

The present invention relates to a mating behavior disorder agent for insect pests.

N-Cyanomethyl-4-trifluoromethyl-3-pyridinecarboxamide (generic name flonicamid) is a compound described as Compound No. 1 in Patent Document 1. Patent Document 2 discloses a pesticidal composition containing a pyridine-based compound including flonikamide and various effect enhancing components.

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

The larvae of the insect pests, which are the major pests in the field of rice cultivation, are highly proliferative and cause great damage to rice. In particular, it is the main damage caused by repetition of multiplication over several generations between brown and red beetles until the harvest time, and causing the group failure of rice. The collective death is the damage caused by rice juice and / or torture by the juice of the brown worm. Presently, the antifungal agent for fungus is a neonicotinoid-based insecticide. Recently, since the insecticidal effect of the neonicotinoid insecticide has been reduced, it has been reported that in the field of rice cultivation, instead of the neonicotinoid insecticide There is a need for a preventive or control method that can become a new mainstream.

The ecology of brownish worms is characteristic, and the present inventors have conducted studies related to their characteristic ecology in controlling wormworms including brownworms.

Brown crabs can not winter in areas north of Vietnam. For example, in Japan, the Jangshi-imago comes flying from the bottom to the bottom during the rainy season from late June to July. The flying density is considerably lower than that of the white fly that is flying from abroad, and the parasitic density at the time of flying does not cause a big problem.

However, after flying, female adult spawning occurs in the tissues of rice paddy sheath through the spawning period of about 4 days, and becomes a next generation (first generation) adult at 25 ° C through egg period 7 to 9 days and larval period 14 days . The female adult of the first generation is often of a simple type with a high growth rate. Because short-lived females do not migrate much and have a large number of laying hens, second-generation populations become localized, and even dense, densely populated, causing cluster testing at the time of the second or third generation.

It is also the same in many countries of South and South Asia where the brown crab can winter, causing serious damage by local proliferation and collective death as described above.

Further, in reality, no pesticides effective against the eggs of brown crabgrass and having safety against the environment and juveniles were found.

From these facts, the inventors of the present invention have found that, in order to find a way to prevent the damage caused by brown worms, the present inventors have found that insects such as insects, Of the population and density of the next generation.

As a result, the inventors of the present invention have found that, among the active ingredients of various pesticides, flonic amide has a mating behavior disturbing action of the insect pest, which solves the above problems, and completed the present invention. The mating behavior disturbance action in the present invention refers to an action in which a female suppresses the action of calling a male by vibration of the abdomen, thereby suppressing a series of mating behavior in which a male finds a female. As a result of this disturbance of mating behavior, the number of laying eggs of the female is decreased, and the eggs scattered do not hatch because they are unfertilized eggs.

That is, the present invention relates to a method for controlling infestation insect pests by acting flornicamid on insect pests, a method for lowering the next generation population of insect pests, and a method for disturbing the mating behavior of insect pests.

The mating action disturbance and the control method of the insect pest of the present invention can exhibit a stable high control effect over a long period of time.

Further, the present invention exhibits an effect that is not expected to lower the number of the next generation of pests, which is clearly distinguished from the use of flonic amide as a simple pesticide. For example, when the seedling box treatment is carried out, it is necessary to treat the dispersing agent a plurality of times because it is impossible to expect a long-term residual effect as a conventionally used controlling agent. In the method of the present invention, It is possible to reduce the number of times. The effect of controlling the juice and insect pests over a long period of time which is normally desired can be exerted, for example, when the present invention is applied to a seedling box treatment by application of an effect which has never been expected to reduce the number of the next generation of insects.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a graph showing the results of suppressing the next generation population when the flocamycin granules were subjected to the seedling box treatment of brown worm adults.
Fig. 2 is a graph showing the results of the suppression effect on the next generation of the population when an adult female seedlings were treated with a seedling box treatment of a granule for treatment with a flocanamide seedling box.

The active ingredient of the pesticide in the present invention is flonicamide. Flonicamid is a generic name and its chemical name is N-cyanomethyl-4-trifluoromethyl-3-pyridinecarboxamide. Flocicamid may form salts.

In the present invention, parasitic juvenile insect pests can be exemplified by ferns, mites, ferns, and the like.

Examples of the dispersing agent include polycarboxylic acids or salts thereof, ligninsulfonic acid or salts thereof and the like. In the case of using the effect enhancer, flonic amide and the effect enhancer may be mixed and formulated together, or they may be separately prepared and mixed. In actual use of these products, they may be used as they are, or diluted to a predetermined concentration with a diluent such as water.

In the present invention, the flonicamide can be treated in a seedling box or treated with rice. In the method of the present invention, seedling box treatment is preferable in that the juice is sucked into the juice insect pests to exhibit a particularly remarkable effect. This is because the flocicamid, which is a pesticidal active ingredient having a high water solubility, can be efficiently taken into the plant by the action of sucking up the medicine from the root of rice by the seedling box treatment.

In the present invention, as described above, the flonic amide can be prepared in various forms, but from the viewpoint that the seedling box treatment is preferable, it is preferable to use the seedlings for seedling box treatment among them.

In order to exhibit the effect of the present invention, suitable granules for treating seedling boxes include a composition containing florinamic acid and a hardly water-soluble resin, wherein the flonicamide and the hardly water-soluble resin are contained in a matrix, To form a composition which is incorporated into the composition of the present invention, which will be described in detail below.

It is known that the active ingredient flonikamide used in the present invention is a compound having a very high water solubility (water solubility at 20 캜: 5200 mg / L). Since it is required to control the elution of the active ingredient of the pesticide since it is necessary to maintain the efficacy of the medicinal product for a long time, it is required to apply a compound having a very high water solubility such as flonycamide to the present application mode It has been said that it is difficult. The above composition is an effective one in solving the problem caused by the water solubility of the flonicamide. The amount is 0.1 to 30% by weight, preferably 0.5 to 25% by weight.

The average particle diameter of the flonic amide used in the present invention is 1 to 500 mu m, preferably 1 to 100 mu m, more preferably 5 to 50 mu m.

Examples of the hardly water-soluble resin that can be used in the present invention include ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-vinyl acetate copolymer, styrene-acrylic acid copolymer, acrylic acid ester, acrylic silicone copolymer, Resins, and petroleum resins. The hardly water-soluble resin is preferably used as an emulsion, and an ethylene-acrylic acid copolymer emulsion is particularly preferable. Examples of the ethylene-acrylic acid copolymer emulsion include HYTEC S-3111, HYTEC S-3121, and HYTEC S-3127 (manufactured by Tohoku Kagaku Kogyo Co., Ltd.). These resin emulsions may be used singly or in combination. The blending amount thereof 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, zircrite, sericite, acidic clay, diatomaceous earth, zeolite, pearlite and attapulgite can be used . Although the amount is not particularly limited, it is in the range of 40 to 99.8% by weight, preferably 60 to 98.5% by weight.

Since the composition uses a hardly water-soluble resin, the wetting agent is preferably added since the degree of familiarity with water is poor and the medicine may float after transplanting into a field cultivated in earnest. Examples of the wetting agent include sodium dioctylsulfosuccinate, sodium alkylbenzenesulfonate, higher alcohol sulfate ester, sodium alkylnaphthalenesulfonate, polyoxyethylene phenyl ether sulfate, polyoxyethylene styrylphenyl ether sulfate, polyoxyethylene alkyl ether and the like. And preferably, polyoxyethylene styrylphenyl ether sulfate. These wetting agents may 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 may be prepared by a conventional method for producing pesticides, for example, an extrusion assembly method, a power assembly method, an electric flow assembly method, a fluidized bed assembly method, a compression assembly method, a stirring mixing assembly method, a cover assembly method or a tableting method.

For example, after mixing flouricamide, wetting agent and carrier uniformly, a lightly water-soluble resin emulsion is added and kneaded with a kneader or the like, followed by granulation by an extrusion granulator such as dome granulation, have.

In addition, in order to further control the dissolution rate according to the desirability of the composition, a dissolution control agent such as paraffin can be added.

In addition to the above-described components, the composition may contain, as optional components, for example, for the purpose of stably maintaining the agricultural chemical active ingredient in the pesticide preparation of the present invention and / , A surfactant, an auxiliary agent, and the like.

In the present invention, if necessary, it can be used in combination with an agricultural chemical ingredient other than flonicamide, for example, a bactericide, an insecticide, a biting agent, a nematicide, an antiviral agent, an attractant, a herbicide, In this case, a superior effect may be exhibited. For example, it is possible to improve the range of application, the timing of chemical treatment, the activity of controlling, and the like in a desired direction. In addition, the active ingredient compounds of flonic amide and other pesticides may be prepared separately by mixing them at the time of dispensing, or they may be used together. For example, in the case of producing the above composition, flonic amide and other pesticide ingredients can be formulated together. The present invention includes the case where the active ingredients are mixed and used as described above.

Test Example 1 Effect of flocicamid seedling box treatment on brown worms

The seedlings prepared according to Formulation Example 1 were treated in a seedling box at a ratio of 1.5 mg ai / week to the seedlings of 1.2 cm x 1.2 cm cell seedlings (3 pcs / week). One day after the flonicamid treatment, rice was released from the cell per soil, transplanted into one pot for one week, and the water depth was maintained at 3 cm. Two small greenhouses were prepared, and 24 ports of each treated and untreated with flonicamid were installed in each small greenhouse. Transplantation 10, 17 and 30 days after the brown myeolgu (Nilaparvata lugens) Each 100 adult two / greenhouse was insecticide (放蟲). After the insecticide, the number of adults per 24 weeks of rice and the number of newly-generated larvae of the next generation, which were parasitized on rice for a certain period of time, were measured. The results are shown in Table 1 and Fig. In Fig. 1, ∘ - ∘ (circled) indicates the number of adult larvae (two) in the flonicamid treatment and Δ - Δ (triangles) indicates the number of adult larvae in the control untreated .

In Table 1 and Fig. 1, from the transition of the 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. The decrease in sex larvae counts on the 39th day after transplanting rice can be presumed to be the state in which the first-generation adults have spawned eggs before hatching. In addition, three adult catches assume a scene where brown crabs fly from another area in an actual rice field. In this situation, no peak of the first generation was observed in the flonicamide treatment, and the second-generation larvae largely suppressed.

Test Example 2: Mating behavior disturbance against brown worms

10 rice seedlings were sown on a 40 mm x 40 mm cotton cloth, and rice seedlings having a height of about 5 cm were prepared. The rice seedlings were immersed in an aqueous solution containing 200 ppm of the active ingredient flornicamid, air-dried and placed in a glass vial bottle (inner diameter 40 mm x height 75 mm; capacity 50 ml). Of the adult US mating state of 1 at the time of the two breeding age larvae brown myeolgu (Nilaparvata lugens) it was housed in a medicament non-treated rice seedlings. From the 6th day to the 24th day after the wing formation, the rice was bred in the dipped rice. On the seventh day after the winging, the male was removed after 24 hours from the incubation of one male of each male on the soaked rice, and the female was scattered to the 14th day after the winging. The number of the larvae of the next generation larvae was measured in comparison with that of the immature treated rice seedlings (flonicamid treatment) and untreated rice seedlings (untreated). In addition, the presence of mating behavior was confirmed by observing for 2 hours when one male of each male was combined.

In order to confirm that there is no next generation larvae in the non-fertilized state, the number of the next generation larvae was measured by cultivating the non-fertilized females alone in the control (non-fertilized). The results are shown in Table 2.

Test Example 3: Mating behavior disturbance of brownish worms with reduced sensitivity to neonicotinoid insecticides

The brownish worms of Test Example 2 were replaced with brownish worms whose sensitivity was lowered to the generic name imidacloprid, which is a representative neonicotinoid-based insecticide, and the test was similarly conducted to prepare the next generation larva Were measured. The results are shown in Table 3.

Test Example 4: Mating behavior disturbance against the white mussels

The brownish worms of Test Example 2 were replaced by Sogatella furcifera and similarly tested, and the number of generations of the next generation larvae was measured in comparison with the treatment with the flonicamid and the control. The results are shown in Table 4.

Test Example 5: Mating behavior disturbance effect on anchovy

Brown myeolgu of Test Example 2, for myeolgu by replacing (Laodelphax striatella) and similarly subjected to the test, compared with respect to the flow NIKA mid-treated and untreated, were measured the number of occurrences of the next generation larvae. 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, mating behavior disturbance is caused to various worms, thereby suppressing the next generation population. In addition, it can be seen that the present invention exhibits an excellent effect even for brown worms whose sensitivity has been reduced to imidacloprid, which has heretofore been used as a mainstream of the worm-controlling agent.

Test Example 6: Mating behavior disturbance against brown worms

The test was carried out in accordance with Test Example 2, except that rice seedlings were treated with an aqueous solution containing 50, 12.5, 3.1 and 0.8 ppm of the effective components flonicamide. The results of measurement of the number of larvae of the next generation in comparison with the treatment with flonicamid and untreated control are shown in Table 6.

Test Example 7: Mating behavioral disturbance against anchovy

The tests were carried out in accordance with Test Example 4, except that rice seedlings were treated with an aqueous solution containing 50, 12.5 and 3.1 ppm of the active ingredient flonikamide. Table 7 shows the results of measuring the number of larvae of the next generation in comparison with the treatment with flonicamid and untreated control.

Test Example 8: Mating behavior disturbance effect on anchovy

The tests were carried out in accordance with Test Example 5, except that rice seedlings were treated with an aqueous solution containing 50, 12.5 and 3.1 ppm of the active ingredient flonikamide. Table 8 shows the results of measuring the number of larvae of the next generation in comparison with the treatment with flonicamid and the untreated control.

Test Example 9: Mating behavior disturbance of brownish worms with reduced sensitivity to neonicotinoid insecticides

A test was conducted in accordance with Test Example 3, except that rice seedlings were treated with an aqueous solution containing 0.8 ppm of the active ingredient flonicamide. Table 9 shows the results of measuring the number of the next generation larvae in preparation for the treatment with flonicamid and the untreated control.

From the results of Test Examples 6 to 9, it can be seen that, in the present invention, mating behavior is disturbed and the next generation population is suppressed even when a low concentration active ingredient, such as 3.1 ppm, is treated for various worms. In addition, even in the case of brown worms whose sensitivity has been reduced to imidacloprid, which has been conventionally used as a mainstream of an antiseptic agent, the present invention is also effective in the case of treating an effective component at a low concentration such as 3.1 ppm .

Test Example 10: Mating behavior disturbance action on endoptera,

The brownish worms of Test Example 2 were replaced by Nephotettix cincticeps and similarly tested. The rice seedlings were treated with an aqueous solution containing 50 ppm of the active ingredient flornicamide 200 mg In contrast, the number of next generation larvae was measured. 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 populations to the endoptera.

Test Example 11 Effect of Floricanamide seedling box treatment on brown worms

The composition for pest control was prepared in a 30 cm x 60 cm seedling box at a ratio of 6, 12, 24 and 36 g ai / box to the seedling box. (24 g ai / box) and imidacloprid granules (trade name: Admiral box granules, manufactured by Bayer Cropsien Co., Ltd.) treatment (manufactured by Mitsui Chemicals, Inc.) 24 g ai / box) was installed. On the day of transplantation, flonicamid was treated and transplanted into a field of 32 m ² per plant by the planting machine. After transplanting 36, 43, 51, 57 and 65 days, 500 eggs each of Brown wilted larvae and 12000 eggs were insected against 100 m ² of field. Transplants 78, 89 and 96 measured the number of adults per 24 weeks of rice and the number of newly generated larvae of parasitized rice. The results are shown in Table 11. In addition, as a reference, FIG. 2 is a graph showing a case of a 24 g ai / 10 a flonicamide treatment for a flonicamide treatment. ● - ● (black circles) indicates the number of sexually active larvae in the 24 g ai / 10 a flonicamide treatment, and □ - □ (white square) indicates the number of sexual dams in the imidacloprid- (Two), Δ - Δ (white triangles) indicates the number of adult larvae in the dinotefuran granulation treatment, and × - × (marks) indicates the number of adult larvae in the control- .

Five insect repellents were carried out according to the time when brown crab was flying from another area in rice fields of southwest Nanji. From the transition of the untreated sex larvae, the 89th day after rice transplantation was the first generation (next generation) peak. In the control starch box treatment, parasitic larvae density was suppressed up to 70 days after transplantation initiation, but then converted to increase. Similarly, in the control solution additive box, the density of parasitic larvae was suppressed up to 70 days after transplantation of irradiation initiation, but then changed to increase, and the first generation (next generation) peak was observed on day 89 after transplantation. Under this situation, no peak of the first generation (next generation) was observed in the flonicamid treatment area, and the number of the newly emerging larvae was largely suppressed up to 89 days after transplantation. This result indicates that the present invention is particularly useful in the scene of rice parasitic juice pest control where there is a demand to suppress the increase in the number of pest populations as long after treatment as possible.

Test Example 12 Effect of treatment with florinamid foliage on brown worms

1 implanted in the field of the sphere 32 m ² by a planting. After transplanting 36, 43, 51, 57 and 65 days, 500 eggs each of Brown wilted larvae and 12000 eggs were insected against 100 m ² of field. After 70 days of transplantation, flocicamid was foliarized in a dispensing quantity of 150 L / 10 a on the heading. (Trade name: Chess hydrating agent, manufactured by Shinzenta) and a treatment solution of dinotefuran receiving agent (trade name: Starck granule accepting agent, manufactured by Mitsui Chemicals, Inc.) were provided. Immediately before treatment, after treatment 2, 8, 19, 26 and 33 days, the number of adults per 24 weeks of parasitized rice and the number of newly generated larvae of the next generation were measured. The results are shown in Table 12.

Five insect repellents were carried out according to the time when brown crab was flying from another area in rice fields of southwest Nanji. From the transition of the untreated adult larvae, the 19th day of treatment was the first generation (next generation) peak. The decrease in sex larvae count on the 26th day of treatment can be presumed to be the state in which the eggs laid by the first generation adult eggs are before hatching. The inhibitory effects of both of the antimetabolite and dinotefuran concentrates were inhibited by the high concentration. Under this situation, first generation (next generation) peaks were not observed in the flonicamide treatment, and the number of emergent larvae was suppressed until 2 to 3 weeks after the treatment.

The present invention can be used for the control of the insect pests, which are insect pests, which are major pests in the field of rice cultivation.
