The impacts of two organic soil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their chemical composition and effect on microbial activity. Also they will have different effects on soil properties and directly and indirectly affect...

Seven species of plant parasitic nematodes were found to be associated with leatherleaf fern (Rumohra adiantiformis) in central Florida. Of these, Pratylenchus penetrans, Tylenchorhynchus claytoni, and Criconemoides curvatum were commonly encountered. Nematode communities generally included two or three species of plant parasitic nematodes, with greatest diversity in nematode species occurring ...

Plants are in constant communication with a multitude of diverse organisms. Some symbioses, such as the association of nitrogen-fixing bacteria and mycorrhizal fungi with plant roots, are beneficial to the plant. Others, such as the interaction of plants with viral, microbial, fungal, and nematode pathogens, are harmful. Most plant-organism interactions go unnoticed simply because they are unde...

Organic matter and its replenishment has become a major component of soil health management programs. Many of the soil's physical, chemical, and biological properties are a function of organic matter content and quality. Adding organic matter to soil influences diverse and important biological activities. The diversity and number of free-living and plant-parasitic nematodes are altered by rotat...

Strigolactones (SLs) are a class of plant hormones that regulate diverse physiological processes, including shoot branching and root development. They also act as rhizosphere signaling molecules to stimulate the germination of root parasitic weeds and the branching of arbuscular mycorrhizal fungi. Although various types of cross talk between SLs and other hormones have been reported in physiolo...

Plant-parasitic nematodes can be very damaging to turfgrasses. The projected cancellation of the registration for fenamiphos in the near future has generated a great deal of interest in identifying acceptable alternative nematode management tactics for use on turfgrasses. Two field experiments were conducted to evaluate the effectiveness of repeated applications of several commercially availabl...

When parasitic plants and aphid herbivores share a host, both direct and indirect ecological effects (IEEs) can influence evolutionary processes. We used a hemiparasitic plant (Rhinanthus minor), a grass host (Hordeum vulgare) and a cereal aphid (Sitobion avenae) to investigate the genetics of IEEs between the aphid and the parasitic plant, and looked to see how these might affect or be influen...
