The present disclosure provides a method for controlling Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4). The present disclosure mainly aims to solve the problem of effectively inhibiting the Foc TR4, but the existing fungicides cannot effectively inhibit the Foc TR4 without damage to banana plants. By treating with the fungicide disclosed by the present disclosure, the growth of the Foc TR4 can be limited, and there is no adverse effect on banana plants.

In crop production in the fields of agriculture, horticulture and the like, the damage caused by insect pests etc. is still immense, and insect pests resistant to existing insecticides have emerged. The present invention has been made in view of such circumstances, and an object of the present invention is to develop and provide a novel agricultural or horticultural insecticide. Another object of the present invention is to provide an agent capable of eliminating ectoparasites or endoparasites of animals. These objects are achieved by a condensed heterocyclic compound having a substituted cyclopropane-oxadiazole group represented by the general formula (1):
