摘要：

This article presents our preliminary experimental data on the release kinetics and encapsulation efficiency of urea formaldehyde (UF) crosslinked matrices of starch (St), guar g-um (GG), and starch + guar gum (St + GG) for the controlled release of solid (chlorpyrifos) and liquid (neem. seed oil) pesticides. The data reveal variable release rates in relation to the polymer type and especially the pesticide type. It is possible to slow the release rates of pesticides using cheaply available materials such as starch and guar gum. (C) 2001 John Wiley & Sons, Inc.
