Description
Summary:Micro‐organisms can be used to provide a crop protection effect, but to exploit this it is necessary to deliver viable micro‐organisms as a formulated product suitable for agronomic application, which presents a significant challenge to formulation technology. Gram‐negative bacterial cells can be formulated in a dry form which is shelf‐stable at elevated temperatures for periods exceeding six months. This paper presents the key physical requirements of the dried formulation required to generate this stability, and a predictive mathematical model of the kinetics of microbial degradation as a function of key physical parameters, for example storage temperature and relative humidity. © 1999 Society of Chemical Industry
