ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an insecticidal and miticidal composition and a method for killing insects and mites.
BACKGROUND OF THE INVENTION
There have been used various compositions for control of insect pests such as mites such as spider mites, and aphids. For example, JP-A-55-57506 discloses a composition for control of insect pests which comprises a combination of sorbitan fatty acid ester or its ethylene oxide adduct and a water soluble polymer. However, the composition has disadvantage that it does not have satisfactory effects if it is used in a low concentration and the effects, if it is expressed, do not last long. Moreover, these mites and insect pests, in general, easily acquire tolerance to drug and therefore the insecticidal and miticidal effects fade away little by little.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an insecticidal and miticidal composition which does not have phytotoxicity but has satisfactory effects even if it is used in a lower concentration and whose effects last long.
The present invention provides an insecticidal and miticidal composition which comprises at least one fatty acid ester selected from the group consisting of glycerin monooleate, glycerin monolinolate, glycerin monocaprylate, glycerin mono/dioleate (a mixture of glycerin monooleate and glycerin dioleate), glycerin di/trioleate (a mixture of glycerin dioleate and glycerin trioleate), glycerin mono/dilinolate (a mixture of glycerin monolinolate and glycerin dilinolate), glycerin mono/diricinoleate (a mixture of glycerin monoricinoleate and glycerin diricinoleate), glycerin diacetomonolaurate, sorbitan laurate, sorbitan oleate, diglycerin laurate, diglycerin oleate, diglycerin monolaurate, diglycerin monooleate, tetraglycerin oleate, hexaglycerin laurate, decaglycerin laurate, propylene glycol monolaurate, and propylene glycol monooleate; and a nonionic surfactant.
PREFERRED EMBODIMENTS OF THE INVENTION
The present invention is accomplished based on the discovery that a combination of a specific fatty acid ester and a nonionic surfactant has remarkably excellent insecticidal and miticidal effects as compared with a combination of other fatty acid ester and a nonionic surfactant.
The present invention provides a miticidal composition which comprises at least one fatty acid ester selected from the group consisting of glycerin monooleate, glycerin monolinolate, glycerin mono/diricinoleate, glycerin diacetomonolaurate, sorbitan laurate, diglycerin laurate, tetraglycerin oleate, propylene glycol monolaurate, and propylene glycol monooleate; and a nonionic surfactant.
Preferably, the miticidal composition of the present invention comprises at least one fatty acid ester selected from the group consisting of glycerin mono/diricinoleate, glycerin diacetomonolaurate, sorbitan laurate, diglycerin laurate, tetraglycerin oleate, and propylene glycol monolaurate; and a nonionic surfactant.
The present invention provides an insecticidal composition which comprises at least one fatty acid ester selected from the group consisting of glycerin monooleate, glycerin monolinolate, glycerin monocaprylate, glycerin mono/dioleate, glycerin di/trioleate, glycerin mono/dilinolate, glycerin mono/diricinoleate, glycerin diacetomonolaurate, sorbitan laurate, sorbitan oleate, diglycerin laurate, diglycerin oleate, diglycerin monolaurate, diglycerin monooleate, tetraglycerin oleate, hexaglycerin laurate, decaglycerin laurate, propylene glycol monolaurate, and propylene glycol monooleate; and a nonionic surfactant.
The present invention provides an aphicidal composition which comprises at least one fatty acid ester selected from the group consisting of glycerin monooleate, glycerin monocaprylate, glycerin mono/dioleate, glycerin di/trioleate, glycerin mono/dilinolate, glycerin mono/diricinoleate, glycerin diacetomonolaurate, sorbitan laurate, sorbitan oleate, diglycerin laurate, diglycerin oleate, diglycerin monolaurate, diglycerin monooleate, tetraglycerin oleate, hexaglycerin laurate, decaglycerin laurate, and propylene glycol monolaurate; and a nonionic surfactant.

The present invention provides a composition for killing thrips which comprises at least one fatty acid ester selected from the group consisting of glycerin monolinolate, glycerin monocaprylate, glycerin mono/dioleate, glycerin di/trioleate, glycerin mono/dilinolate, glycerin mono/diricinoleate, glycerin diacetomonolaurate, sorbitan laurate, sorbitan oleate, diglycerin laurate, diglycerin oleate, diglycerin monolaurate, diglycerin monooleate, tetraglycerin oleate, hexaglycerin laurate, decaglycerin laurate, propylene glycol monolaurate, and propylene glycol monooleate; and a nonionic surfactant.
Preferably, the composition for killing thrips of the present invention comprises at least one fatty acid ester selected from the group consisting of glycerin diacetomonolaurate, glycerin monocaprylate, glycerin mono/dilinolate, sorbitan oleate, diglycerin oleate, and propylene glycol monooleate; and a nonionic surfactant.
Preferably, the nonionic surfactant used in the present invention is polyoxyethylene alkyl ether wherein the alkyl group has 6 to 24 carbon atoms, preferably 6 to 18 carbon atoms and the molar number of added ethylene oxide is 3 to 20, preferably 3 to 10.
In the composition of the present invention, the amount of the nonionic surfactant is preferably 1 to 40 parts by weight, more preferably 5 to 20 parts by weight, most preferably 8 to 10 parts by weight, per 100 parts by weight of the fatty acid ester.
The composition of the present invention preferably comprises a medium chain fatty acid triglyceride as an auxiliary agent for the preparation. The medium chain fatty acid triglyceride is very stable fats and oils and used in the field of lubricants and cosmetics. An alkyl group in the medium chain fatty acid triglycerides has preferably 7 to 11 carbon atoms. If the medium chain fatty acid triglyceride is used in the composition of the present invention, the amount thereof is preferably 1 to 40 parts by weight, more preferably 5 to 20 parts by weight and most preferably 5 to 10 parts by weight per 100 parts by weight of the fatty acid ester.
