Benefits of technology

The present invention provides an enhancer composition for agricultural chemicals that can significantly enhance the effectiveness of various agricultural chemicals by adding a nitrogen-containing compound and a chelating agent to the chemical. The nitrogen-containing compound can be an organic tertiary amine, a tertiary amine salt, or a quaternary ammonium salt. The chelating agent can be a specific type of nitrogen-containing compound called a tertiary amine. The content of the nitrogen-containing compound and the chelating agent in the composition can range from 0.01 to 30 mol per mol of the nitrogen-containing compound. The invention also provides an agricultural chemical composition containing this enhancer composition and a method for enhancing the effectiveness of agricultural chemicals by applying this enhancer composition. The nitrogen-containing compound can be added in a ratio of 0.01-30 mol per mol of the chelating agent. The invention also provides an agricultural chemical kit that includes the enhancer composition and other components such as a surfactant or an adjuvant for penetration of agricultural chemicals. The nitrogen-containing compound can be selected from a group of compounds such as amines, quaternary ammonium salts, and tertiary amine salts.

Problems solved by technology

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.
However, the enhancement effect of the above described compounds capable of enhancing the effectiveness of agricultural chemicals is not always satisfied.
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.
However, this patent does not suggest the combination use of an organic quaternary ammonium salt as a cationic surfactant and a chelating agent.

example 2

[0185] Female imagines of Tetranychus kanzawai kishida were planted onto kidney bean leaf disks at a ratio of 30 imagines per lot on three runs and then incubated at 25.degree. C. for 24 hours. Subsequently, the whole leaf disks were dipped in a test solution for 5 seconds. After taking out of the test solution and allowing to stand at 25.degree. C. for 48 hours, the leaf disks were observed and the miticidal ratios thereof were determined on the basis of the result in the untreated lot (refer to the following equation). 2 Miticidal ratio ( % ) = the number of living mites of an untreated lot - the number of living mites of a test lot the number of living mites of an untreated lot .times. 100

[0186] As miticides, Nissorun V emulsion (containing 55% by weight of active ingredients including 50% by weight of hexythiazox and 5% by weight of DDVP) and Osadan wettable powder 25 (containing 25% by weight of phenbutatin oxide as the active ingredient) were each diluted 3,000-fold with the u...

example 3

[0189] Rice planthopper larvae of the third instar were incubated and used in an efficacy test on insecticides in triplicate runs by the dipping method (each lot having 10 larvae). The insecticidal ratio was determined in the same manner as the one employed for the determination of the miticidal ratio. Commercially available insecticides, i.e., Sumithion emulsion (containing 50% by weight of MEP as the active ingredient) and Malathon emulsion (containing 50% by weight of malathon as the active ingredient) were each diluted 3,000-fold with the use of deionized water, and the dilutions thus obtained were used. As the enhancer compositions for agricultural chemicals, those employed in Example 1 were used in such a manner as to adjust the concentration of each enhancer composition [i.e., sum total of compound (A), chelating agent (B) and surfactant (C)] in the diluted solution to 0.1% by weight. Tables 9, 10-1 and 10-2 show the results.
