Ecophysiological Parameters:
Microbial Antagonists
Commercial microbial antagonist formulations performed poorly against Tylenchulus semipenetrans and Paratrichodorus lobatus compared to the nematicides Aldicarb, cadusafos and metalaxyl (Walker and Morey, 1999a)
Green Manures:
Paratrichodorus lobatus reached high levels in pots containing unamended soil but was not detected in pots containing soils amended with Brassica cultivars Ebony and Indian mustards, and Rangi rape residues (Walker and Morey, 1999b).
