Title (EN) STARCH ENCAPSULATION OF BIOCONTROL AGENTS
(FR) ENCAPSULATION DANS UNE MATRICE D'AMIDON D'AGENTS BIOREGULATEURS
Abstract:
(EN) 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.
(FR) Des agents de régulation biologique tels que des virus et des bactéries pathogénétiques sont encapsulés dans une matrice protectrice à base d'amidon sans utiliser d'agents chimiques de réticulation. L'agent est mélangé dans une dispersion d'amidon prégélatinisée qui est ensuite soumise à des conditions appropriées à une rétrogradation. Des dispersions peuvent être formulées soit pour des granules secs soit pour des liquides atomisables. Des produits encapsulés sont utiles pour lutter contre des insectes et autres espèces nuisibles ayant des parties de bouche de mastication et des enzymes digestives d'amylase.
