Encapsulation can be used to mitigate the degradation of pesticides in a hostile environment. The design of the right release profile, however, is critical to tune the balance between the degradation and uptake into plants for pest control. In this paper, we use Compound A, an insecticide that undergoes rapid degradation in soil, as an example to demonstrate how mathematical modeling combined with a greenhouse study, can be utilized to suggest an optimal release profile and help the design of controlled-release formulation for an active ingredient (AI). First, a mathematical model was constructed to understand the minimum dosage requirement to meet the 1-month insect control target. Then a spiking greenhouse test with the defined use rate was designed to validate the model. Combination of these data led to the determination that the minimum dosage in microbiologically active soil for 1-m.. View More»
