Abstract EN
The interaction between Meloidogyne incognita (race 2) and Rhizoctonia solani (AG 4) in a root rot disease complex of green beans (Phaseolus vulgaris) was examined in a greenhouse pot experiment.
Three week-old seedlings (cv.
Contender) were inoculated with the nematode and/or the fungus in different combinations and sequences.
Two months after last nematode inoculation, the test was terminated and data were recorded.
The synchronized inoculation by both pathogens (N + F) increased the index of Rhizoctonia root rot and the number of root galls; and suppressed plant growth, compared to controls.
However, the severity of root rot and suppression of plant growth were greater and more evident when inoculation by the nematode preceded the fungus (N fi F) by two weeks.
Nematode reproduction (eggs/g root) was adversely affected by the presence of the fungus except by the synchronized inoculation.
When inoculation by nematode preceded the fungus, plant growth was severely suppressed and roots were highly damaged and rotted leading to a decrease of root galls and eggs.
