Article: Formulating Biologicals: Encapsulation and Stability

Jim Bullock, August 2019

When formulating biological actives for crop protection, the main challenge is that of stability – in the case of natural extracts such as peptides and proteins there can be chemical or physical mechanisms for instability and in the case of microbials,biological stability can be an issue. Additionally, the stability of the product to degradation by UV light can also be important and challenging.

One of the ways in which formulators can protect the active against degradation is by using microencapsulation technologies. As well as improving stability, microencapsulation can be used control the rate of release of an active or to reduce the exposure of the user to the active for reasons of safety…
