摘要：

The pesticides diazinon, trifluralin, and alachlor were successfully encapsulated into temperature-responsive Intelimer microcapsules. The pesticides were differentially released into aqueous solutions at predictable rates in response to temperature. The response of corn (Zea mays L.) insect pests Diabrotica balteata LeConte (banded cucumber beetle) and Diabrotica virgifera LeConte (western corn rootworm) with the insecticide diazinon confirmed the temperature activity relationship of the encapsulated formulations compared to a commercial formulation. Encapsulation of trifluralin reduced com injury in response to soil applications and reduced the need for immediate soil incorporation compared to the commercially used emulsifiable concentrate formulation. Encapsulated alachlor prolonged the control of large crabgrass [Digitaria sanguinalis (L.) Scop.] and reduced leaching in soil compared to an emulsifiable concentrate formulation.
