Plastic metallic mulch has provided important benefits in field tests. Metallic mulch benefits include reduction of virus vectoring aphids on cucurbits (melons, squash and cucumbers) and decreased viral infection, thus increasing the percentage of marketable fruit. A tomato test showed reduction of silverleaf whitefly populations, decreasing incidence of tomato mottle virus. The silver color of this mulch seems to confuse certain insects, because the light reflection disorients them. It is recommended that Metallic mulch be used on a trial basis. 1.25 mil.
