Description

  The present invention relates to (RS) -N- [2- (1,3-dimethylbutyl) thiophen-3-yl] -1-methyl-3-trifluoromethyl-1H-pyrazole-4-carboxamide (generic name penthiopyrad) And a composition containing at least one pyrethrin or synthetic pyrethroid as an active ingredient is applied to plant seeds to prevent plant pest damage.

  Pest damage can occur not only in the above-ground parts of plants but also in soil. Most of the damage in the soil is caused by eating pests that damage the roots, i.e. plant roots, or by entering plant pathogens from damaged sites that have been harmed by the pests.

  Seed germination, sprouting, and initial plant growth are particularly important because the roots and stems of the growing plants are small and the entire plant can wither even in small amounts of damage. Control of pests that attack seeds and plant parts on the ground during the initial stage of plant growth has been variously studied in the agricultural field. Currently, it is common to apply pesticides mainly to soil or foliage to control pests that harm crops after germination.

  The foliage treatment usually requires treatment when pests are present in order to be most effective. Therefore, when it is difficult to treat the medicine due to rain or the like, there are cases where the effect cannot be exhibited. Furthermore, in order to efficiently control pests, it is necessary to closely observe the occurrence of pests. It is known that a synthetic pyrethroid agent exhibits an excellent control effect against lepidopterous pests such as weevil by applying to the soil surface as such a foliar treatment agent or at the time of sowing. However, since this type of insecticide is extremely toxic to aquatic organisms such as fish, great attention must be paid to spillage during soil surface treatment or foliage spraying or transfer to water due to drift.

  Penthiopyrad as a bactericidal compound is applied by seed disinfection, foliar spraying, and other methods such as rice blast (Piculararia oryzae), sesame leaf blight (Cochliobolus miyabeanus), blight (Rhizoctonia solani), and idiotic buri , Wheat powdery mildew (Erysiphe graminis), leafy leaf disease (Pyrenophora graminea), snow rot (Typhula sp,), naked smut (Ustylago tritici), grape powdery mildew (Uncinula necto) Podosphaera leukotricha, powdery mildew of cucurbits (Sphaerotheca fulignea) Although it is described in JP-A-9-235282 that it is effective in preventing the disease by applying methods such as spraying treatment, smearing treatment, dipping treatment or dressing treatment to plant seeds. No indication is given.

  In addition, as conventional agents for preventing plant diseases by applying to plant seeds, there are benomyl agents, thiophanate methyl agents, prochloraz agents, pephrazoate agents, etc., which are spraying treatment, smearing treatment, dipping treatment or powdering to seeds. It is known to be effective in clothing processing. However, among these agents, it has been reported that benomyl agents and thiophanate methyl agents have reduced control effects on some pathogens such as rice blast fungus and sesame leaf blight fungus. Prochloraz is applicable to rice blast disease, sesame leaf blight, stupid seedling disease, tulip bulb rot, and rakkyo dry rot in seed treatment, but there is no report that other diseases can be prevented. Similarly, although the pefazoate agent is applied to rice blast, sesame leaf blight, stupid seedling, wheat red snow rot, and tulip bulb rot in seed treatment, there is no report that other diseases can be prevented.

  An object of the present invention is to provide an improved method for preventing damage to pests such as phytopathogenic fungi and pests that damage plant seeds and plants grown from them by applying to plant seeds.

  As a result of intensive studies in view of such circumstances, the present inventors have found that a composition comprising penthiopyrad and at least one pyrethrin or synthetic pyrethroid as an active ingredient exhibits a high preventive effect on a plurality of diseases and pests at a low dose, and an existing drug It has been found that a stable preventive effect is exhibited even against resistant bacteria of the present invention, and the present invention has been achieved.

  That is, the present invention is a method for preventing disease and pest damage of plant seeds and plants grown from them, characterized in that a composition comprising penthiopyrad and at least one pyrethrin or synthetic pyrethroid as active ingredients is applied to the plant seeds.

  The method of the present invention exhibits a high preventive effect against disease and insect damage occurring on plant seeds at a low dose, and also exhibits a stable preventive effect against existing resistant bacteria.

  An example of a disease that can be prevented by the method of the present invention is shown below.
