Description

  The present invention relates to an insecticidal composition for home gardening. More specifically, the surface activity found in an aqueous formulation (insecticidal composition for home gardening) containing an insecticidal component and a specific surfactant (alkylbenzene sulfonic acid or salt thereof) that is applied without dilution. The present invention relates to an insecticidal composition for home gardening in which phytotoxicity caused by the agent is reduced.

  Conventionally, insecticides, fungicides, and insecticides that are diluted with water as agricultural chemicals for general farmers have been sold. In addition, pesticides for home gardening that are diluted with water are also sold. However, since it takes time and effort to dilute with water, pesticides, fungicides and insecticides that can be sprayed without dilution are now available. Bactericides have become the mainstream pesticide for home gardening. Since agricultural chemicals for general farmers are diluted, auxiliary components (surfactants, stabilizers, etc.) in the agricultural chemical are also diluted, so the risk of phytotoxicity to plants due to auxiliary components is small, In the case of pesticides sprayed for the purpose of pest control in home gardening, the toxicity of the ingredients to plants may be a problem. Especially in home gardening, the appearance of petals is regarded as important, and the occurrence of chemical damage to petals should be considered It has become. For agricultural chemicals for home gardening, surfactants such as alkylbenzene sulfonic acid or its salts, which are considered to have high phytotoxicity but high emulsification stability, are intended for general farmers in order to improve spreadability or maintain long-term emulsification stability. It may be used at higher concentrations than pesticides, and there is a high risk of phytotoxicity occurring in plants (Agricultural Chemicals Formulation Guide, edited by the Japanese Pesticide Society, page 177, published in October 1997; Non-Patent Document 1). Plant petals are susceptible to phytotoxicity due to the effects of alkylbenzene sulfonic acid or its salts, and it is therefore desirable to reduce the phytotoxicity.
