    DETAILED DESCRIPTION
    In one embodiment of the present invention, the method of protecting a seed or the body of a plant growing from a seed against an arthropod pest comprises the steps of:
    a) form a groove in the ground;
    b) that includes
    place in the groove formed in the previous stage a seed that retains triacloprid at least on its surface and
    apply to the groove formed in the previous stage a pesticidal composition comprising one or more synthetic pyrethroid compounds selected from group I (group I: the group consisting of sphevalerate, beta-cypermethrin, theta-cypermethrin, deltamethrin, fenpropatrin, tau-fluvalinate, beta-ciflutrin, acrinatrine, alpha-cypermethrin, biphentrine, cycloprotrin and etofenprox; and
    c) close the groove.
    The shape of the groove formed in the soil at stage a is not particularly limited and can usually be a linear groove having a V-shaped section. The depth of the groove may vary depending on the species of crop to be cultivated, the land conditions of the cultivation area, the cultivation conditions, the meteorological conditions and the like. For example, in the case of corn, the depth is usually 1 to 10 cm, preferably 2 to 8 cm and more preferably 2 to 6 cm.

    by a component attached to the seeder.
    In step b, the placement of a seed that retains at least its surface thiacloprid and the application of a pesticidal composition comprising one or more synthetic pyrethroid compounds selected from group I (hereinafter also referred to as "synthetic pyrethroid compound of the present invention "), which is also referred to herein as" synthetic pyrethroid composition of the present invention ", can be carried out simultaneously or separately. If carried out separately, the placement of the seed in the groove may be followed by the application to the groove of the synthetic pyrethroid composition of the present invention, and the application of the synthetic pyrethroid composition of the present invention to the groove may be followed by the placement of the seed in the groove.
    Thiacloprid ((Z) -3- (6-chloro-3-pyridylmethyl) -1,3-thiazolidin-2-ylidenecyanide) is a known compound and is described, for example, in "The Pesticide Manual - 16th edition (published by BCPC); ISBN 978-1-901396-86-7 ", page 1102. Thiacloprid has been used as an insecticide and is available as a commercial formulation or can be produced by a known procedure.
    In the present invention, a seed that retains at least its surface tiacloprid means a seed that has been previously treated with tiacloprid and can be obtained by treating a seed with a composition comprising thiacloprid (hereinafter referred to as "composition of the present invention"). The composition of the present invention relates to a formulation obtained by mixing thiacloprid with a solid vehicle or an appropriate liquid vehicle, adding thereto a surfactant or other adjuvant for formulation, if necessary, and formulating the resulting product as a powder. water dispersible, a water dispersible granule, a fluidizable concentrate, a powder composition or the like. When using the composition of the present invention it is usually mixed with a binder. The composition of the present invention may also contain a binder. Examples of the composition of the present invention containing a binder include a fluidizable concentrate for seed treatment (FS).
    As a binder, an adhesive substance that has no phytotoxic effects on the seeds is used. Specifically, at least one selected from the group consisting of the following may be used: polyvinyl acetate, polyvinyl alcohol, celluloses, including

    ethyl cellulose, methyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose and carboxymethyl cellulose, polyvinyl pyrrolidone, polysaccharides, including starch, modified starch, dextrin, maltodextrin, alginate and chitosan, proteins, including gelatin and zein, gum arabic, lacumide, methacum, lacumide, lacumide, methacum, lacumide, lacumide, lacumide, methacrylic acid The amount of binder is usually in the range of 0.00005 to 5%, preferably 0.0001 to 1% and more preferably 0.0005 to 0.5%, based on the weight of the seeds.
    Examples of the process for seed treatment include smeared treatment, immersion treatment, powder coating treatment and granule treatment. The smeared treatment is a procedure in which if necessary the composition of the present invention is mixed with a binder, subsequently diluted with water if necessary, spread on a seed and dried. The immersion treatment is a process in which a seed is immersed in a liquid obtained by mixing if necessary the composition of the present invention with a binder and subsequently the resulting is diluted with water if necessary and then dried. The powder coating treatment is a procedure as follows: if necessary the composition of the present invention is mixed with a binder and if necessary it is subsequently processed to give a powder to obtain a solid composition, and the solid composition of the present invention adheres to the seeds and dries. The granule treatment is a procedure as follows: if necessary the composition of the present invention is mixed with a binder and if necessary it is subsequently processed giving a powder to obtain a solid composition, and the solid composition of the present invention is adheres to the seeds; and the resulting product is molded to give a granule and dried. The seed thus obtained is a seed coated with the composition of the present invention. In the present invention, said seed can be used immediately after treatment with the composition of the present invention, but is usually used one or more days after treatment. The phrase "that retains thiacloprid at least on its surface" means that it encompasses not only a state of retention in which thiacloprid is adhered to the surface of the seed, but also a state of retention in which thiacloprid penetrates into the interior of the seed across the surface of the seed.
    In the present invention, "which is coated" does not only refer to a state in which the surface of the seed is fully coated, but refers to a state in which the composition of the present invention is adhered to a surface partial of the seed.

    Therefore, it is not necessary to coat the entire surface of a seed. It is preferred that at least 80% of the total surface area of a seed be coated and it is more preferred that at least 90% of the total surface area of a seed be coated. When the seeds are to be treated with a pesticide or the like, it is a general practice to add a dye to the pesticide or the like to ensure that the pesticide or the like has properly adhered to the seeds. Consequently, taking as an example the adhesion treatment of thiacloprid in the present embodiment, the addition of a certain dye to the composition comprising thiacloprid makes it possible to determine, using image analysis, etc., the proportion of the retention area of tiacloprid with respect to to the total surface area of the seed, based on the proportion of the surface area to which the dye adheres with respect to the surface of the seed.
    In the present embodiment, the amount of thiacloprid conserved by a seed may vary appropriately depending on the culture conditions of the crop, weather conditions and the like, and is usually 0.01 to 40 g, preferably 0.05 to 10 g and more preferably 0.5 to 5 g, per kilogram of seeds.
    Examples of the procedure for placing the seed in the groove in stage b include a procedure that involves manual placement and a procedure that involves placement using a seeder that operates manually or mechanically.
    In step b, examples of the synthetic pyrethroid compound of the present invention contained in the pesticide composition applied to the groove include sphevavarate, beta-cypermethrin, theta-cypermethrin, deltamethrin, fenpropatrin, tau-fluvalinate, beta-ciflutrin, acrinthrin, alpha- cypermethrin, biphentrine, cycloprotrin and etofenprox.
