Benefits of technology

[0016]The pesticide composition according to the present invention employs a compound represented by chemical formula (I) or chemical formula (II) as the pesticide efficacy potentiating agent along with the pesticidal active ingredient to potentiate the efficacy of the pesticidal active ingredient. Further, the pesticide composition according to the present invention is highly stable and does not cause chemical damage or the like.
[0017]The method for potentiating the efficacy of the pesticidal active ingredient of the present invention enables potentiation of the efficacy of the pesticidal active ingredient which is employed. As a result, it is possible to reduce the amount of pesticidal active ingredient employed and to decrease chemical damage.

Problems solved by technology

However, the method of fully drawing out the effects of the pesticidal active ingredient and enhancing the effects of the pesticide by manipulating the type of formulation has limitations.
However, while the pesticide efficacy potentiating agent disclosed in this reference is capable of potentiating the efficacy of the pesticidal active ingredient and thus decreasing the amount of pesticide employed, chemical damage sometimes depending on the use.

example 1

[0085]2.5 parts Newcol 2308LY (manufactured by Nippon Nyukazai Co., Ltd) employed as compound (I) or compound (II) (hereinafter referred to as “efficacy potentiating agent I”), 2.2 parts acetamiprid employed as the pesticidal active ingredient, and 12.5 parts γ-butylolactone and 82.8 parts dipropylene glycol employed as the solvent were mixed and dissolved to obtain a uniform pesticide composition 1.

example 2

[0086]2.5 parts of an efficacy potentiating agent I employed as the compound (I) or the compound (II), 2.2 parts acetamiprid employed as the pesticidal active ingredient, and 12.5 parts N-methyl-2-pyrrolidone and 82.8 parts dipropylene glycol employed as the solvent were mixed and dissolved to obtain a uniform pesticide composition 2.

examples 3 to 5

[0093]Efficacy potentiating agent I, employed as compound (I) or compound (II), was added by stirring to each of the commercially available pesticide formulations aqueous Mospilan {4000 fold, manufactured by Nippon Soda Co., Ltd. (identical below)}, Nab emulsion {1000 fold, manufactured by Nippon Soda Co., Ltd. (identical below)}, and Topsin M wattable powder {(1000 fold, manufactured by Nippon Soda Co., Ltd. (identical below)}, to reach a concentration of 750 ppm, 500 ppm, and 250 ppm, respectively, thereby formulating pesticide compositions 4 to 6.

Further the present invention provides a method for potentiating the efficacy of the pesticidal active ingredient comprising using a compound represented by chemical formula (I) or chemical formula (II) in combination with a pesticidal active ingredient.

Description

TECHNICAL FIELD[0001]The present invention relates to a pesticide composition containing a pesticide efficacy potentiating agent and a pesticidal active ingredient, and to a method for potentiating the efficacy of a pesticidal active ingredient.[0002]Priority is claimed on Japanese Patent Application No. 2007-226839, filed Aug. 31, 2007, the content of which is incorporated herein by reference.BACKGROUND ART[0003]Numerous pesticide compositions, such as insecticides, fungicides, herbicides, miticides, plant growth regulators and the like, have long been employed. In order to fully draw out the effects of the pesticidal active ingredient, various trials have been carried out with respect to the type of formulation, i.e., emulsion, wattable powder, granules, powder, flowable agent, etc.[0004]However, the method of fully drawing out the effects of the pesticidal active ingredient and enhancing the effects of the pesticide by manipulating the type of formulation has limitations.[0005]A ...
