It is an object of the present invention to provide a pest control composition capable of exerting a high effect on pests such as spider mites and aphids even at low concentration using a food/food additive with high safety to the human body and the environment. The present inventors have intensively studied to solve the above problem and found that, among polyglycerol fatty acid esters widely used as a food additive, a composition containing a polyglycerol fatty acid ester which has an HLB of 5 or less and is liquid at ordinary temperature and also a nonionic surfactant has a high effect on pests even at low concentration, and that the possibility for pests to develop resistance to the composition is extremely low, and the present invention has been completed.
A pest control composition consisting of
A pest control composition consisting of a pest-controlling effective amount of a polyether-modified organopolysiloxane as a nonionic surfactant and a polyglycerol fatty acid ester having an HLB of 5 or less selected from the group consisting of hexaglycerol pentaoleate, decaglycerol decaoleate, decaglycerol erucate and polyglycerol condensed ricinoleate.
A method for controlling a pest consisting of
