摘      要：Root-knot nematodes(RKNs)are obligate endoparasites that feed on their host plants to complete its life cycle,representing a major threat to agriculture and economy *** development of new management strategies becomes essential as effective chemical nematicides are progressively being ***,we analysed grape pomace-derived biochars,pyrolysed at 350°C(BC350)and 700°C(BC700),focusing on their potential for RKN *** thermal treatment of grape pomace caused an increase in the concentration of carbon and plant macro-and micronutrients,which were largely present in a water-soluble *** radiation-based Fourier transform infrared microspectroscopy data showed a general loss of carboxylic functional groups during pyrolysis,partially contributing to the alkalinisation of both biochars,mostly in *** electron microscopy coupled with energydispersive X-ray spectroscopy analysis revealed a highly porous structure filled with different crystals composed of elements such as K,Ca,Mg,P,Si or Al,which could be a suitable environment for the growth of ***-derived aqueous extracts showed phytotoxicity to tomato seedlings at high concentrations,and disappeared upon dilution,but no toxic effect was observed on the nematode’s infective ***,the infective and reproductive traits of a Meloidogyne javanica population in tomato were significantly reduced(*** masses and eggs per plant)in washed-biochar-treated soil in pots(0.75%;BC350W).Therefore,the large amount of grape waste generated after wine production can be transformed into a valuable product such as biochar,effective for RKNs control,thus reducing the waste management problem and contributing to a circular economy.
