Abstract:
In a continuing program to develop biodegradable plastics for mulch and other agricultural applications, we found that incorporating water-soluble, biodegradable plasticizers and low-density polyethylene into starch ethylene acrylic acid copolymer (EAA) films increased the rates of biodegradation without adversely affecting plastic properties. Adding a strong base to the starch-EAA formulation caused the films to have semipermeable or dialysis characteristics. A new technique was developed for encapsulating pesticides that is based on a starch-borate complex. In addition to a wide range of other applications, starch-encapsulated herbicides may play an important role in controlling weed problems associated with plastic tunnels, without crop injury.
