In the field of rice cultivation, the planthoppers, which are regarded as the main insect pests, have high fertility and cause great harm to rice. In particular, the brown planthopper is tied to the harvesting period and has been repeatedly propagated for several generations, causing the hopper burn to be the main hazard. The so-called "burning" is the hazard of rice death and/or fall caused by the harm of the brown planthopper. Nowadays, the new nicotine-based insecticides are the main control agents for the planthoppers, but in recent years, the planthoppers in the field of rice cultivation have been rapidly observed due to the rapid observation of the susceptibility to the new nicotine insecticides. Seek to be a new mainstream control agent or prevention method.

The ecological characteristics of the brown planthopper, the inventor of this case is related to the control of the planthopper containing the brown planthopper, and its characteristics are related to the study.

The brown planthopper is unable to winter in the area north of Vietnam. For example, in Japan, mainly during the rainy season from late June to July, long-winged adult insects flying from the lower jet stream are used as sources of origin. Compared with the white flyback that is also flying overseas, the density of flying is quite low, and it does not cause big problems in the parasitic density at the time of flying.

However, after flying, the female adult system lays eggs in the rice sheath sheath tissue during the pre-emergence period of 4 days, and goes to the next generation (the first generation) at 25 ° C for 7 to 9 days and the larval period for 14 days. Generation) adult. Most of the female adults of the first generation have a short-wing type with a high reproductive rate. Because the short-winged females do not move, the number of eggs laid is also large. The second generation of individual groups is local and the density is increased by geometric progression, causing sputum burning in the second generation or the third generation.

In addition, even in the Southeast Asian countries where there are too many Vietnam, the brown planthoppers have the same hazards caused by local reproduction and calcination.

In addition, there is a pesticide that is not effective against the eggs of the brown planthopper, and has safety against the environment and beneficial insects.

In view of the fact that the inventors of the present invention have focused on the method of preventing and controlling the damage of the brown planthopper, focusing on the method of not allowing the flying adult and the first generation adult to lay eggs, making it difficult to lay eggs, and preventing the eggs from hatching, etc., The number or density of individuals in the next generation is reduced.

As a result, the inventors of the present invention have found that among various active ingredients of the agricultural chemical, flunidom has solved the problem, and the present invention has been completed by the action of the action of the sucking insects. The term "interference action" in the present invention refers to a behavior that inhibits the female to use the vibration of the abdomen to call the male, and suppresses the action of the male to find one of the females. In this way, the result of interfering with the mating action, the number of eggs laid by the females is reduced, and further the eggs are not hatched because the eggs are unfertilized.

That is, the present invention relates to a method for controlling the sucking of pests by causing flunidom to act on sucking pests, a method for reducing the number of individuals under the sucking pests, and a method for interfering with the feeding action of the sucking pests.

The anti-tailing action interfering agent and the control method of the sucking pest of the present invention can achieve a stable and high control effect for a long period of time.

Further, the present invention draws a clear line with the use of flunidom as a simple pesticidal agent, achieving a completely unexpected effect of lowering the number of individuals in the next generation of pests. For example, in the case of the nursery box treatment, in the conventional control agent, since the residual effect for a long period of time cannot be expected, the dispersing agent must be treated plural times, but at least the number of times of the dispersing agent treatment can be reduced. The completely unexpected effect of "reducing the number of individuals in the next generation of pests" disclosed in the present invention is applied, for example, to the case of the nursery box treatment, and the control effect of the sucking pests is maintained for a sufficiently long period of time which is usually desired. .

(Best form of implementing the invention)

The active ingredient of the pesticide in the present invention is fluniin. Flonidamide is generally known by the chemical name N-cyanomethyl-4-trifluoromethyl-3-pyridinecarboxamide. Flunidamide has a salt formation.

In the present invention, the rice parasitic sucking pests can be exemplified by flying mites, leaf mites, mites and the like.

Examples of the mites are: brown planthopper, white-backed planthopper, spotted locust, etc.; leaf mites can be exemplified by black-tailed spider mites; and mites can be exemplified by blind mites and red-striped scorpions.

In the present invention, the sucking pests are preferably exemplified by planthoppers and spider mites. More preferred examples are: locusts.

The dispersant can be exemplified by a polyvalent carboxylic acid or a salt thereof, lignosulfonic acid or a salt thereof and the like. In the case where the potency enhancing component is used, flunidom may be mixed/formulated together with the potency enhancing component, or may be separately prepared and mixed. When these preparations are actually used, they can be used as they are, or diluted with a diluent such as water to a predetermined concentration.

In the present invention, fluniin is capable of treating a nursery box or a paddy field. In the method of the present invention, since a particularly remarkable effect is achieved by causing the pest to absorb juice, it is desirable to treat the seedling box. Flunidamine, an agricultural active ingredient having a high water solubility, can be effectively inhaled into a plant by sucking it from the root of the rice in accordance with the nursery box treatment.

In the present invention, although it can be formulated into various forms as described above, it is desirable to prepare a granule for treating a seedling box from the viewpoint of the desired seedling box treatment.

A granule suitable for the treatment of the seedling box for exerting the effects of the present invention can be exemplified by a composition having the following characteristics: using a composition containing fluniin and a poorly water-soluble resin, the preparation of fluniflune and The poorly water-soluble resin is a matrix, that is, a composition obtained by forming a water-soluble resin containing flunisamine, which will be described in detail below.

A compound having a very high water solubility of the active ingredient of the present invention, which is used in the present invention (water solubility at 20 ° C: 5200 mg / L). Since the medicament for the treatment of the nursery box must be sustained for a long period of time, it is sought to control the melt extrusion of the agricultural active ingredient, and on the other hand, it has become difficult to apply a compound having a very high solubility in water such as finnish to the present use form. This composition is effective in solving the problem of solubility in the water of the finnishide. The blending amount is from 1 to 30% by weight, preferably from 0.5 to 25% by weight.

Oxidized polyethylene, urethane resin, petroleum resin, and the like. The poorly water-soluble resin is desirably used as an emulsion. It is particularly desirable to be an ethylene-acrylic acid copolymer emulsion. Examples of the ethylene-acrylic acid copolymer emulsions include HYTEC S-3111, HYTEC S-3121, HYTEC S-3127 (manufactured by Toho Chemical Co., Ltd.), and the like. These resin emulsions can be used not only alone but also after mixing. The solid content is from 0.1 to 30% by weight, preferably from 1 to 15% by weight, based on the blending amount.

The carrier to be used in the present invention is not particularly limited, and for example, clay, bentonite, talc, calcium carbonate, sericite, Zeeklite (trade name), acid gypsum powder, diatomaceous earth, zeolite, wave iron, green can be used. Carriers such as waves and stones. The blending amount is not particularly limited and is in the range of 40 to 99.8% by weight, preferably 60 to 98.5% by weight.

This composition is inferior in affinity to water in order to use a poorly water-soluble resin, and it is desirable to add a wetting agent since it floats after transplanting rice fields. Examples of the humectant are sodium octyl sulfosuccinate, sodium alkylbenzene sulfonate, higher alcohol sulfate, sodium alkylnaphthalene sulfonate, polyoxyethylene phenyl ether sulfate, polyoxyethylene styryl phenyl. An ether sulfate, a polyoxyethylene alkyl ether or the like is exemplified as polyoxyethylene styrylphenyl ether sulfate. These humectants can be used not only alone but also after mixing. In the case of using a wetting agent, the blending amount is not particularly limited and is 0.01 to 10% by weight, preferably 0.1 to 5% by weight.

The composition can be produced by a granulation method generally used in the manufacture of agricultural chemicals, for example, by extrusion granulation, rotary granulation, rotary flow granulation, fluidized bed granulation, compression granulation, stirring and mixing. It is prepared by a granulation method, a coating granulation method, a tableting method, and the like.

For example, after uniformly mixing the fluniin, the wetting agent, and the carrier, the water-insoluble resin emulsion is added, and the mixture is kneaded by a kneader or the like, and granulated by a die granulator such as a dome-granule. The composition can be obtained after granulation.

Further, in order to further control the melt extrusion speed in accordance with the requirements, the composition can be added with a melt extrusion controlling agent such as paraffin.

In addition to the above-mentioned components, for example, in the agricultural chemical preparation of the present invention, for the purpose of stably securing the active ingredient of the agricultural chemical and/or improving the granulation property at the time of granulation, if necessary, A surfactant, an adjuvant, or the like can be contained as an optional component.

In the present invention, if necessary, it is possible to mix and use agricultural ingredients other than finnish, for example, fungicides, insecticides, mites, nematicides, antiviral agents, attractants, herbicides, plant growth regulators. In this case, further excellent effects are also exhibited. For example, the application range, the period of the drug treatment, the control activity, and the like can be improved in a preferable direction. Further, flunidomide and other agricultural active ingredient compounds may be used by mixing the preparations at the time of dispersion, or may be used together. For example, in the case of modulating the composition, it is also possible to prepare the florine together with other pesticide components other than the other. In the present invention, in such a manner, the case where the active ingredient is mixed and applied is also included.
