Abstract

La présente invention concerne un agent de lutte physique contre des petits insectes nuisibles comportant de l'eau et un polymère hydrosoluble qui se dissout dans l'eau et forme un film par l'évaporation de l'eau. Lorsque l'agent de lutte physique est pulvérisé sur des petits insectes nuisibles, le polymère hydrosoluble s'adhère à une aile ou une patte du petit insecte nuisible abasourdi. Au fur et à mesure de l'évaporation de l'eau dans l'agent de lutte physique, le polymère hydrosoluble forme un film, et interdit le vol ou la marche des petits insectes nuisibles, et finit par les exterminer. La présente invention réduit l'utilisation de pesticides pour prévenir l'empoisonnement d'humains et ne pas gêner la croissance de cultures. La présente invention utilise l'eau comme solvant pour assurer une efficacité économique, et peut facilement éliminer le polymère hydrosoluble des cultures par une utilisation répétée.
