  Vapormate^TM has potential as a niche methyl bromide replacement for disinfestation of fresh produce. It contains 16.7% (by weight) of ethyl formate dissolved in liquid CO₂ (equivalent to 11% by volume when vaporised). Ethyl formate is a GRAS compound approved as a food additive by the USFDA. It has long been registered in Australia for use as a dried fruit fumigant (registered by Orica as Eranol®).

Ethyl formate occurs naturally in foods, kills insects rapidly, has low human toxicity and breaks down quickly into natural products. Vapormate^TM is o­ne of BOC’s Envirosol ® products which uses liquid CO₂ as a solvent-propellant to dispense bioactive compounds either as non-flammable gaseous mixture (such as Vapormate^TM) or as aerosol particles. In addition to eliminating flammability, the synergistic effects of CO₂ may enhance the efficacy of the active compounds. Registration of Vapormate^TM is proceeding in Australia and New Zealand. Crop & Food Reaserch in New Zealand and UC Davis in California are investigating the efficacy of Vapormate^TM for fruit and vegetable disinfestation and CSIRO in Australia are evaluating its potential for protecting stored grain from insect pests.

This paper will review research regarding efficacy of Vapormate^TM o­n a range of quarantine pests and summarise produce tolerance for a range of fruits and vegetables. In addition, an update will be provided o­n application methods and o­n progress with registration.
