biopesticide based on chitosan and entomopathogenic nematodes.

摘要

The invention consists of a new pesticide formulation, biostimulant and fungicidal effects linking action biostimulation by the chitosan to the biological control of plagues in agricultural and forest crops due to phytopathogenic insects by entomopathogen nematodes of the families Steinernematidae and Hererohabditidae. There is a synergistic action between bioestimualnte and biological pesticide due to the action of symbiotic bacteria Xenorhabdus and Photorhabdus genera queportan nematodes of these families. The aforementioned action is synergically enhanced by the bio-stimulating effect of chitosan on plants to promote root development and degree of lignification and cause elicitaciónde genes producing phytoalexins as a defensive mechanism.
