摘要： An insect pest-repelling film or sheet is disclosed, having a reflective spectrum in a ultraviolet region of a wavelength of less than 0.4 .mu.m, particularly a reflective spectrum peak at a wavelength of less than 0.4 .mu.m, a reflective spectrum having not less than 1.4 of a ratio (R.sub.A /R.sub.B) of the ultraviolet reflectance (R.sub.A) and a visible light reflectance of a wavelength of 0.5 .mu.m (R.sub.B) and a visible light transmission of not less than 40%. The film is useful as a cover of houses and tunnels or mulching of ground for crop culture or as a repellent for various insect pests in agriculture, forestry, and gardening.

摘要： The invention provides an agricultural film of a polyolefin composition from 0.02 to 0.5 part by weight of an .omega.-hydroperfluoroalkyl group-containing fluorine compound surfactant and from 0.5 to 5 parts by weight of a nonionic dripping agent per 100 parts by weight of a polyolefin resin. The agricultural film can prevent fog generation in houses, tunnels or the like in horticulture use facilities.
