Starch of biocontrol agent occluded

摘要

Biological control agents such as pathogenic bacteria and viruses have been encapsulated in a protective, starch matrix without the use of chemical crosslinking agents. The agent is blended into a dispersion of pregelatinized starch, which is thereafter subjected to conditions suitable for retrogradation. Dispersions can be formulated either for recovery of dry granules or as sprayable liquids. Encapsulated products are useful in controlling insects and other pest species having chewing mouth parts and amylase digestive enzymes.
