Interaction of Population Levels of Fusarium oxysporum f. sp. vasinfectum and Meloidogyne incognita on Cotton.
In autoclaved greenhouse soil without Fusarium oxysporum f. sp. vasinfectum, Meloidogyne incognita did not cause leaf or vascular discoloration of 59-day-old cotton plants. Plants had root galls with as few as 50 Meloidogyne larvae per plant. Root galling was directly proportional to the initial nematode population level. Fusarium wilt symptoms occurred without nematodes with 77,000 fungus prop...
متن کامل1274 Origin and evolution of Fusarium oxysporum f. sp. vasinfectum: A case study in Australia
In Australia, indigenous Fusarium oxysporum consist of at least five genetically distinct lineages and the two strains (VCG 11&12) of F. oxysporum f. sp. vasinfectum (Fov) are genetically related to lineage A, suggesting that they evolved locally. This is consistent with the observation that virulence of a lineage A isolate increased after 10 successive infections on susceptible cotton in the g...
متن کاملInteractions of concomitant species of nematodes and Fusarium oxysporum f. sp. vasinfectum on cotton.
Meloidogyne incognita, Hoplolaintus galeatus, and North Carolina and Georgia populations of Belonolaimus longicaudatus were introduced singly and in various combinations with Fusarium oxysporum f. sp. vasinfectum on wilt-susceptible 'Rowden' cotton. Of all the nematodes, the combination of the N. C. population of B. longicaudatus with Fusarium promoted greatest wilt development. H. galeatus had...
متن کاملLocal origin of two vegetative compatibility groups of Fusarium oxysporum f. sp. vasinfectum in Australia
Pathogenicity and genetic diversity of Fusarium oxysporum from geographically widespread native Gossypium populations, including a cotton growing area believed to be the center of origin of VCG 01111 and VCG 01112 of F. oxysporum f. sp. vasinfectum (Fov) in Australia, was determined using glasshouse bioassays and AFLPs. Five lineages (A-E) were identified among 856 isolates. Of these, 12% were ...
متن کاملSurvival of Fusarium oxysporum f. sp. vasinfectum Chlamydospores Under Solarization Temperatures
Bennett, R. S. 2012. Survival of Fusarium oxysporum f. sp. vasinfectum chlamydospores under solarization temperatures. Plant Dis. 96:1564-1568. Solarization is an effective soil treatment against race 4 of Fusarium oxysporum f. sp. vasinfectum. Despite the lack of effective alternatives, solarization is rarely used in cotton because of its high cost. Use of solarization might be increased if so...
