No. 08/507,483 filed on Aug. 28, 1995, which is the national phase of International Application No. PCT/JP94/02263 filed on Dec. 27, 1994, which claims priority on Japanese Application No. 5-337502 filed on Dec. 28, 1993. The entire contents of each of the above-identified applications is hereby incorporated by reference.
- 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.
- 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.

- It has been a practice to add a small amount of a chelating agent to a surfactant by which the efficacy of an agricultural chemical can be enhanced [see Japanese Patent Publication-A Nos. 2-295907 (published on Dec. 6, 1990) and 4-502618 (published on May 14, 1992), and European Patent Publication-A No. 36106]. In these cases, however, the addition of the chelating agent aims mainly at trapping substances which are contained in the water for diluting the agricultural chemical and inhibit the activity of the agricultural chemical, namely, trace metal ions (e.g., Ca++, Mg++) to thereby;soften hard water. Therefore, chelating agents are used in the prior art only in a small amount. In contrast, a chelating agent is used in a large amount in the present invention compared with the conventional cases. The present inventors have found for the first time that the efficacy of an agricultural chemical can be remarkably enhanced by using a chelating agent in a larger amount than the conventional dose together with the above-mentioned nitrogen-containing compound.
- [III] Enhancer Composition for Agricultural Chemicals
- The enhancer composition for agricultural chemicals of the present invention comprises the above-mentioned nitrogen-containing compound (A) and the chelating agent (B). When used in combination with an agricultural chemical, this enhancer composition for agricultural chemicals can enhance the efficacy of the agricultural chemical twice to thrice without causing any phytotoxicity. Namely, the enhancer for agricultural chemicals of the present invention can be safely applied to various crops without causing any phytotoxicity.
- Although the mechanism of action of the enhancer composition for agricultural chemicals of the present invention has not been necessarily clarified, it is considered as follows. The nitrogen-containing compounds employed in the present invention are those positively charged in water. Therefore, it specifically adheres to cell membranes of plants, microorganisms and insects, invades the membranes and then abnormally elevates the flowability of the cell membranes, thus causing a disturbance in the membrane functions. As a result, the amount of the agricultural chemical incorporated into the cells is increased and thus the efficacy of the agricultural chemical is enhanced. It is estimated that the chelating agent undergoes some interaction with the nitrogen-containing compound to thereby enhance the efficacy of the agricultural chemical. Accordingly, it seems that the effect of the chelating agent in the present invention essentially differs from the effect, which has hitherto been lectured, of a chelating agent of trapping trace metal ions in water and thus enhancing the efficacy of an agricultural chemical. It has been observed in practice that the effect of a nitrogen-containing compound according to the present invention in enhancing the efficacy of an agricultural chemical is strengthened by adding a chelating agent both in distilled water and in hard water.
- In the enhancer composition for agricultural chemicals of the present invention, the dose of the above-mentioned nitrogen-containing compound (A) can be reduced while maintaining the enhancing effect thereof on an agricultural chemical by further using a surfactant (C) other than the nitrogen-containing compounds (A) and/or an adjuvant for penetration of agricultural chemicals (D) therewith.

- Examples of suitable ampholytic surfactants include lauryldimethylamine oxide, Armox C/12, amine oxides, Monaterics, Miranols, betaines, Lonzaines, other amine oxides and mixtures thereof.
- Among these surfactants, nonionic surfactants, anionic surfactants and mixtures of a nonionic surfactant and an anionic surfactants are preferable, and mixtures of a nonionic surfactant and an anionic surfactants are still more preferable. Among these mixtures, those in which the weight ratio of the nonionic surfactant to the anionic surfactant ranges from 1/50 to 50/1 are desired, and those in which the weight ratio ranges from 1/30 to 15/1 are particularly desired.

Among anionic surfactants, polyoxyalkylene alkyl ether sulfates, alkylbenzene-sulfonates, and linear and branched alkyl polyoxyalkylene ether acetic acids and salts thereof are preferred and polyoxyalkylene alkyl ether sulfates and linear and branched alkyl polyoxyalkylene ether acetic acids and salts thereof are particularly preferred.

- The above-mentioned enhancer compositions listed in Tables 3, 4-1 and 4-2 were each dissolved in deionized water to give a 0.05% by weight [as sum total of compound (A), chelating agent (B) and surfactant (C)) dilution. With the use of the 0.05% by weight dilution thus obtained, commercially available herbicides, i.e., Karmex wettable powder (containing 78.5% by weight of DCMU as the active ingredient), Herbiace liquid formulation (containing 20% by weight of Bialaphos as the active. ingredient) and Roundup liquid formulation (containing 41% by weight of isopropylamine salt of Glyphosate as the active ingredient) were each diluted 500-fold. Thus three agricultural chemical compositions were obtained for each enhancer composition for agricultural chemicals.
- Fertile soil obtained from a paddy field, gravels (i.e., river sand) and a culture soil available on the market were mixed one another at the weight ratio of 7:2:1. Pots having an inside diameter of 12 cm were filled with the soil thus obtained. In order to conduct a glasshouse-test, the seeds of crabgrass were sowed in the pots and germinated. The pots wherein the growth of the crabglass was abnormal were abandoned to reduce the irregularity among pots. The pots wherein crabgrasses had been grown at a height of about 18 cm were used in the test. Spray gun (mf. by Iwata Tosoki Kogyo K.K., type RG) was used for the application of the agricultural chemical compositions to the crabgrasses. The crabgrasses in the pots were uniformly sprayed with each of the agricultural chemical compositions at a ratio corresponding to 1000 1/ha (liter per hectare) to evaluate the herbicidal efficacy.

- As Tables 5 to 12-2 clearly show, since the chelating agent further enhanced the effect of at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt in enhancing the efficacy of the agricultural chemicals in the enhancer compositions for agricultural chemicals of the present invention, the enhancer compositions for agricultural chemicals of the present invention exhibited remarkable effects of enhancing the efficacy of the agricultural chemicals.
- When a chelating agent was used alone, the efficacy of an agricultural chemical could be somewhat enhanced thereby but the effect could not attain any practically usable level.
- Accordingly, it has been found that in the enhancer compositions for agricultural chemicals of the present invention, the chelating agent specifically enhances the effect of at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt of enhancing the efficacy of the agricultural chemicals.
- The same test as the one effected in Example 1 was carried out by using Roundup liquid formulation (containing 41% by weight of active ingredient) as a herbicide, and the formulation Nos. 13, 27 and 32 of Example 1 as enhancer compositions each in the amount as specified in Table 13. Table 13 shows the results. In Table 13, the term “herbicide concn.” means the concentration of the marketed herbicide formulation in a dilution to be applied, the term “enhancer compn. concn.” means the concentration of the enhancer composition [i.e., sum total of compound (A), chelating agent (B) and surfactant (C)] in a dilution to be applied, and the term, “agricultural chemical” means the active ingredient(s) of the marketed herbicide formulation.

- The above-mentioned enhancer compositions for agricultural chemicals listed in Table 14 were each dissolved in deionized water to give a 0.05% by weight [as sum total of compound (A), chelating agent (B) and surfactant (C)] dilution. With the use of the 0.05% by weight dilution thus obtained, commercially available herbicides, i.e., Karmex wettable powder (containing 78.5% by weight of DCMU as the active ingredient), Herbiace liquid formulation (containing 20% by weight of Bialaphos as the active ingredient) and Roundup liquid formulation (containing 41% by weight of isopropylamine salt of Glyphosate as the active ingredient) were each diluted 700-fold. Thus three agricultural chemical compositions were obtained for each enhancer composition for agricultural chemicals.
