Isolation of native fungi for handling of plant parasitic nematodes of tomato’rhizosphere

摘要: 41 native fungi were isolated from five agro ecosystems in the provinces of Chimborazo (4 samples) and Tungurahua (1 sample). The main genera found were for Aspergillus, Penicillium, Trichoderma, Mucor, Alternaria, Fusarium, Acremonium, Paecylomices among others. Using the technique of bait nematodes (Wyborn et al. 1969), isolates were compared with a suspension of 90 nematodes, divided into 3 groups of 30 individuals. The nematode species used corresponded to Passalorus present in feces rabbit. after 96 hours, the number of parasitized or inactive nematodes were counted. The data obtained were analyzed by nonparametric tests (test kruskalwallis) results showed highly significant (< 0.0001), so a comparison of medians were performed, according to the ranking. The native isolates GUC, GUE, UTD, GUL, SLJ were the best statistically, followed by the PAD, SLB, SLE, SJA strains. Pathogenicity …
