Control of plant parasitic nematodes with trans-chalcone.

摘要

THE TRANS-chalcone (1,3-diphenyl-2-propene-1-one) is a product derived bioengineered OF PROPANE FENIL CHARACTERIZED by having two aromatic rings joined by a chain with a carbonyl SYSTEM TO BE UNSATURATED. It has been found that this molecule HAS A POWERFUL AND NEMATOSTATICA FOR ACTION NEMATICIDE plant parasitic nematodes (Formula I). The object of the invention DEFINE A NON-DESCRIBED PREVIOUSLY SUBSTANCE CONTROL plant parasitic nematodes. ALSO OBJECT OF THE INVENTION TO GIVE NEW USES TRANS-chalcone as nematicide and NEMATOSTATICO (irreversibly inhibits the hatching of second-stage juveniles nematode cyst). Such uses are not evident STATE OF THE ART. OBJECT OF THE INVENTION INDUSTRIAL APPLICATION SUSCEPTIBLE AND THEREFORE CAN BE OBTAINED BY SYNTHESIS CHEMICAL PLANT AS DIRECTLY.
