Polyethylene spunbond nonwoven date-bunch covers are an urgently needed, price-competitive alternative to mesh covers made of synthetic monofilament yarn. They are the first improvement to the ideal date-bunch cover that USDA researchers theorized seventy years ago, by adding dust and mold spore exclusion, yet providing sufficient shade and vapor transmission for proper ripening. Black mold is insignificant even under close tree spacing and “wet summer” conditions. The lowered temperature and increased humidity inside the cover promotes pliable, smooth skin instead of dry and brittle as commonly occurs with covers made of monofilament mesh fabric. Covers made of polyethylene spunbond nonwoven fabric are lighter, less abrasive, compress easier, and thus are far more user-friendly. Ripe dates can be held on-tree longer than was ever possible before without accumulating dust or losing quality, which renders unnecessary the labor-intensive practice of multiple pickings, and saves cold storage costs.
