Abstract
The invention relates to paintball-pellet-type projectiles containing insect pheromones encapsulated in an aqueous oil-in-water-type formulation. Said formulations can release said pheromones in a sustained manner. Said projectiles are characterised in that they contain the aqueous formulation of encapsulated pheromone compatible with the envelope of the projectile composed of oxo-degradable polymer. The aim of the invention is to use said projectiles to treat trees against insect pests by spraying and bursting said projectiles on the trunks of said trees.
Claims16
A projectile comprising a shell and a fill material wherein the shell comprises
- an oxo-degradable thermoplastic polymer or copolymer which is selected from the group consisting of oxo-degradable polyefins, and in that the fill material consists of an aqueous formulation of “oil-in-water” emulsion type wherein the aqueous phase comprises a gelling agent and the oil phase comprises a matrix consisting of a mixture of oil and/or wax and pheromone.
