ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an enhancer composition for agricultural chemicals, an agricultural chemical composition, a method for enhancing the effectiveness of an agricultural chemical, a use of the above-mentioned enhancer composition for agricultural chemicals for the preparation of an agricultural chemical composition, a use of the above-mentioned enhancer composition for agricultural chemicals for enhancing the effectiveness of an agricultural chemical and an agricultural chemical kit.
2. Description of the Related Art
Agricultural chemicals including insecticides, fungicides (or bactericides), herbicides, miticides (or acaricides) and plant growth regulators have been used in the forms of, for example, emulsions, wettable powders, granules, powders and flowables. In the properties of these agricultural chemical preparations, various attempts have been made to achieve the maximum effectiveness of the agricultural chemicals. However, it has been difficult to enhance the effectiveness of agricultural chemicals through adjustments in formulations. It is further difficult to develop novel agricultural chemicals. Therefore, further enhancement of existing agricultural chemicals would highly contribute to the industry.
As substances capable of enhancing the effectiveness of agricultural chemicals, surfactants comprising various nitrogen-containing compounds such as quaternary ammonium salts, betaines and amine oxides have been known (see European Patent Publication-A No. 274369, published on Jul. 13, 1988). It is known that quaternized or further polyoxyethylenated long-chain amines, among the above-mentioned compounds, are effective for this purpose. However, the enhancement effect of the above described compounds capable of enhancing the effectiveness of agricultural chemicals is not always satisfied.
Since an agricultural chemical is diluted with water prior to use, it contains a chelating agent for trapping metal ions, etc., existing in the water. For example, European Patent Publication-A No. 36106 (published on Sep. 23, 1981) has disclosed a herbicide composition comprising a phosphinothricin derivative, a specific quaternary ammonium salt and a chelating agent. However, particular examples of the quaternary ammonium salts disclosed in this patent include ammonium sulfate, ammonium nitrate, ammonium acetate and the like, and do not include organic quaternary ammonium salts generally used as cationic surfactants. Further, Japanese Patent Publication-A No. 55-98105 (published on Jul. 25, 1980) has disclosed a herbicide composition comprising a bisphosphonic acid herbicide and a chelating agent. However, this patent does not suggest the combination use of an organic quaternary ammonium salt as a cationic surfactant and a chelating agent.
DISCLOSURE OF THE INVENTION
SUMMARY OF THE INVENTION
From a standpoint that the efficacy of an agricultural chemical can be enhanced by using the agricultural chemical together with at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt, the present inventors have conducted extensive studies. As a result, they have found that the efficacies of various agricultural chemicals can be remarkably enhanced by adding a nitrogen-containing compound together with a chelating agent thereto. The present invention has been completed on the basis of this finding.
Thus, the present invention provides an enhancer composition for agricultural chemicals comprising at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt and a chelating agent, wherein the content of the chelating agent ranges from 0.01 to 30 mol per mol of the nitrogen-containing compound. The nitrogen-containing compound is preferably a nitrogen-containing surfactant selected from the group consisting of an organic tertiary amine, an organic tertiary amine salt and an organic quaternary ammonium salt.
Further, the present invention provides an agricultural chemical composition comprising an agricultural chemical, at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt and a chelating agent, wherein the content of the chelating agent ranges from 0.01 to 30 mol per mol of the nitrogen-containing compound and the weight ratio of the total of the nitrogen-containing compound and the chelating agent to the agricultural chemical ranges from 0.05 to 50.
Furthermore, the present invention provides a method for enhancing the effectiveness of an agricultural chemical which comprises applying the above-mentioned enhancer composition for agricultural chemicals with an agricultural chemical to a locus which would be benefit from such treatment, a use of the above-mentioned enhancer composition for agricultural chemicals for the preparation of an agricultural chemical composition, and a use of the above-mentioned enhancer composition for agricultural chemicals for enhancing the effectiveness of an agricultural chemical.
In addition, the present invention provides an agricultural chemical kit which comprises a container containing the above-mentioned enhancer composition for agricultural chemicals and a container containing an agricultural chemical composition, an agricultural chemical kit which comprises a container containing the above-mentioned enhancer composition for agricultural chemicals, a container containing a surfactant other than the above nitrogen-containing compounds and a container containing an agricultural chemical composition, an agricultural chemical kit which comprises a container containing the above-mentioned enhancer composition for agricultural chemicals, a container containing an adjuvant for penetration of agricultural chemicals and a container containing an agricultural chemical composition, and an agricultural chemical kit which comprises a container containing the above-mentioned enhancer composition for agricultural chemicals, a container containing a surfactant other than the above nitrogen-containing compounds, a container containing an adjuvant for penetration of agricultural chemicals and a container containing an agricultural chemical composition.
In this specification, the term “agricultural chemical” means one which is employed as an active or principle ingredient in common agricultural chemical compositions or preparations, and examples thereof include a fungicide (or a bactericide), an insecticide, a miticide (or an acaricide), a herbicide, a plant growth regulator and the like.
Further the scope and the applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples which follow, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
