PROBLEM TO BE SOLVED: To provide a multilayer mulch film for agriculture which is excellent in increased soil temperature suppression and the protection from insect pest which comes flying by optimally controlling the reflection of sunlight.SOLUTION: The invention provides an insect repellent mulch film 1 for agriculture having a light reflex layer 10 containing a titanium dioxide and metal microparticles. The thickness of the light reflex layer 10 is in the range of 5-30 μm, the concentration C1 of the titanium dioxide is in the range of 10-25 wt.%, and the reflectance of the light reflex layer is 10% or more in the wavelength of 360 nm, and 60-80% in the wavelength of 450 nm.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】太陽光線の反射を最適に制御して地温上昇抑制と害虫飛来防止に優れた農業用多層マルチフィルムを提供する。【解決手段】二酸化チタンと金属微粒子を含有する光反射層10を有する農業用虫除けマルチフィルム1であって、光反射層10の厚みが5~30μmの範囲にあり、二酸化チタンの含有濃度C1は10~25wt%の範囲であり、光反射層の反射率が波長360nmで10%以上、波長450nmで60~80%であることを特徴とする農業用虫除けマルチフィルム。【選択図】図1
