Objective(s):
The purpose of the Plasticulture Working Group (PLAST) is to encourage and facilitate the mutual exchange of ideas and information concerning the use of plastics in various aspects of horticultural research, extension, education, and industry.

Innovative uses of plastics will be discussed in the context of high tunnel tomatoes; row covers for vegetable crop production in tropical and temperate climates; and one presentation will focus on utilizing biodegradable mulch (BDM) to increase sustainability of high tunnel tomato production in northwestern Washington.  An update on recycling of used agricultural plastics will be provided by an industry member.  Because of high soil and organic matter contamination, used agricultural plastics are notoriously hard to recycle.  Several successful attempts have been made in the past 2-3 years, and examples of these will be discussed, including a full recycling process in California that includes washing systems, shipment to overseas recyclers, and incineration to provide energy for cement-making operations in Florida and Guatemala.  There will be another talk on how high tunnels are being used to extend the growing season of fresh vegetables in an urban environment (Philadelphia).  While high tunnels for vegetable production offer well-defined benefits, growers have difficulty practicing crop rotation and this increases risks of soil-borne diseases.  Accordingly, the influence on grafting on fruit yield and quality of tomatoes grown in high tunnels will be discussed in relation to a recent trial at the Rutgers Ag Research and Extension Center, Bridgeton, NJ. Finally, a recently retired land grant extension specialist will discuss his new E-advisory service for over 100 strawberry plasticulture growers in 12 eastern states. The Strawberry Plasticulture E-Advisor, serves to “translate” weather forecast information from SkyBit Inc.’s patented Strawberry Canopy Forecast, into actionable, preventive measures - using row covers and/or sprinkler irrigation.
