Plastic mulch technology has come a long way in the last 15 years and has made another exponential jump in the last five years.
Traditionally plastic films used in plasticulture production systems were simple, single-layer, low-density polyethylene films. These are reasonably priced and for the production systems they were and are still used in, they suited the purpose.
Historically speaking, they were used in combination with methyl bromide for soil fumigation purposes. Methyl bromide use is now gone for pre-plant fumigation in Florida, and growers are left with other options such as Telone, chloropicrin, Vapam, K-Pam, Paladin, and now Dominus.
