Abstract
The present invention relates to liquid formulations containing pheromones, in particular sex pheromones of insects, as an active ingredient, supported by an inert liquid material whereby a film-forming resin is formed on the surface of the liquid material when exposed to oxygen. The liquid pheromone formulations may be sprayed onto the leaves of plants and cured in situ on the leaves. The cured pheromone formulation is capable of controlled release of the pheromone over a period of time.
Claims15
A liquid formation for spraying onto the leaves of plants comprising an amount of pheromone effective to control insects;
- a mixture of copolymers of vinyl-ethylene with vinyl acetate and butylphthalate, and a solvent;
- whereby a film is formed on the surface of the liquid formulation when exposed to oxygen.
A liquid formulation for spraying onto leaves of plants comprising between about 5 and to 25 wt % of a pheromone;
- between about 60 and 90 wt % of a mixture of copolymers of vinyl-ethylene with vinyl acetate and butylphthalate;
- and between about 5 to 20 wt % of a solvent.
A method of controlling insects comprising applying a liquid formulation onto leaves of plants, the liquid formulation comprising an amount of pheromone effective to control insects;
- a mixture of copolymers of vinyl-ethylene with vinyl acetate and butylphthalate;
- and a solvent;
- whereby a film is formed on the surface of the liquid formulation when exposed to oxygen.
