Biologiese beheer van plantparasitiese nematodes met die swam Paecilomyces lilacinus by aartappels, sitrus en wingerd

[摘要] ENGLISH ABSTRACT: Paecilomyces Ii/acinus, ras 251 (geregistreer in terme van wet 36 van 1947 as Suid-Afrika se eerstenatuurlike nematisiede en kommersieel beskikbaar as PI Plus) is as biologiese beheer agent getoets byaartappels en in geïntegreerde beheer programme by sitrus en wingerd teen respektiewelik Me/oidogynespecies, Ty/enchu/us semipenetrans en verskeie ektoparasitiese nematodes. Die swam toon belofte virdie beheer van hierdie nematodes en het terselfdertyd nie 'n nadelige effek op nie-teiken, voordeligeorganismes in die grond nie. Veral in kombinasie met chemiese middels, as deel van geïntegreerdeprogramme, kan dit lei tot verminderde gebruik van hoogs toksiese middels en dus meeromgewingsvriendelike landboupraktyke.Biological control of plant parasitic nematodes on potatoes, citrus and grapevine with thefungus, Paecilomyces liIacinus.Paecilomyces liIacinus, race 251 (registered in terms of act 36 of 1947 as South Africa's first naturalnematicide, commercially available as PI Plus) was tested as a biological control agent on potatoes andin integrated control programs on citrus and grapevine against Me/oidogyne species, Ty/enchu/ussemipenetrans and various ectoparasitic nematodes respectively. The fungus shows promise for thecontrol of these nematodes, without having a harmful effect on non-target, beneficial organisms in thesoil. Especially in combination with chemical products, as part of integrated programs, this can lead toless use of highly toxic compounds and thus to more environmentally friendly agricultural practices.
