can be used to encapsulate aqueous solutions, lipophilic substances, and emulsions of lipophilic and aqueous materials. Finely divided suspensions with particle sizes up to 400 microns (0.4 mm) also can be encapsulated.can be produced as small as about 0.2 mm and as large as about 15 mm in diameter at present. As compared with conventional microcapsules of only a few microns in diameter, Hydrocapsules provide a more favorable surface-volume ratio, with a reduced chance of desiccation. Because they contain a larger internal volume than conventional microcapsules, the cost of encapsulating a quantity of bait should be less than with microcapsules. are large enough to be directly detectable by target pests, such as fire ants, which carry them into the nest and consume the contents. are "rainproof" since they are designed to contain 100% water indefinitely and they can be stored in bulk in water. can provide protection of the contents from UV - since they are made using a UV process. However, additives can be put into the polymer shell to allow degradation and eventual breakdown by UV over time once the capsules are put into the field.Contents are sequestered from exposure to air and anti-oxidants such as alpha-tocopherol, BHA, BHT, or tertiary butyl hydroquinone also can be included to reduce oxidation of fatty acids and other labile agents. are 'flowable' and ameliorate problems in distributing otherwise sticky/gooey baits. They can be used to encapsulate biopesticides or entomopathogenic organisms such as protozoa, bacteria, viruses, fungi, & nematodes, as well as IGRs and conventional pesticides. |
