Abstract

In a greenhouse experiment, Arthrobotrys conoides and A. oligos­poral showed the highest efficiency in reducing M.incognita population during the first 4 weeks affter planting. Paecilomyces lilacinus, Verticilli­urn chlamytiosporium and Trichoderma harzianvm, on the other hand, gave their maximum effect 8 weeks after planting. Out of all fungi test­ed, P. lilacinus achieved significantly the highest percentages of reduc­tion on both nematode galling and L2 in soil, 8 weeks after planting. V. chlamydosporium and Trichoderma harzianum generally resulted in mod­erat reductions of nematode counts, during all the tested intervals. After 12 weeks from planting, nematode suppression declined in all tested fungal treatments; however, P. filacinus was the most effective and Arthrobotrys spp were the least effective.
