This study was to determine whether Arthrobotrys flagrans, A. oligospora, and Meria coniospora would control the root-knot nematode Meloidogyne hapla on alfalfa and tomato. Alfalfa seeds were coated with a fungus-rye powder in 2% cellulose and were planted in infested soil. Three-week-old seedlings from seed treated with M. coniospora had 60% and 58% fewer galls in two experiments than did seed...

The influence of climate and time of deposition on the colonization of sheep faeces by nematophagous fungi was examined in the Mata Region of Minas Gerais State, Brazil. Sheep faeces were collected from the rectums of animals and deposited on pastures of Brachiaria decumbens in the months of July and October 1995 and January and April 1996. Samples of the deposited faeces were recovered 3, 7 an...

Aggressiveness of fifteen isolates of Phaeoisariopsis griseola and variations in angular leaf spot symptom development in common bean were studied. The isolates were selected based on their virulence and genetic differences and represented Andean, Afro-Andean and Mesoamerican groups of P. griseola. Aggressiveness was determined based on length of incubation period, rate of lesion expansion, les...

BACKGROUND Biological control of gastrointestinal nematodes of ruminants by use of nematophagous fungi would become part of any livestock parasite integral control system. Identifying autochthonous species that could then be selected for mass production is an important phase in the practical use of biological control. AIMS To search for nematophagous fungi with potential use as biological con...
