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 characterized in that the shell comprises an oxo-degradable thermoplastic polymer or copolymer 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.
Use of a projectile according to one of the preceding claims for protecting a stand of trees against an insect pest characterized by the fact that the projectile is projected and bursts on the trunk of the trees of the stand to be protected;
- preferentially the projectile is projected with sufficient force to cause the shell to burst and to cause all or part of the fill material to adhere to the trunk.
