Abstract
Controlled release of juvenile hormones into aqueous environment is accomplished with aliginate gel discs containing the juvenile hormone; said gel discs comprising a solubilizing agent, a water soluble algin, a salt which yields cations which gelatinize alginates, a biocide and a juvenile hormone, such as 4-ethylphenyl geranyl ether epoxide.
Claims3
A method for the controlled release and protecting of an insect juvenile hormone from chemical degradation when said hormone is applied to an aqueous environment employing gel discs, said discs comprising a water soluble algin, a calcium salt which yields cations which gelatinize alginates, a solubilizing agent to control gel formation, a biocidally effective amount of a biocide to protect said discs from attack by microorganisms and an insect juvenile hormone.
