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 Cof 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 1 |
