First Report of Gray Leaf Spot (Pyricularia grisea) on Perennial Ryegrass (Lolium perenne) in New England

ACREMONIUM-ENDOPHYTES OF PERENNIAL RYEGRASS (Lolium perenne) IN FRANCE

13-17 ABSTRACT Infection with endophytic fungi (Acremonium spp.) was detected in seeds of wild populations of perennial ryegrass (Lolium perenne) collected in France by private breeding companies and INRA. In total, 262 populations were examined and 70% contained Acremonium. It is worth noticing that most populations are endophyte infected but generally endophyte infection rates per population ...

The effects of maleic hydrazide on growth control of perennial ryegrass (lolium perenne L.CV. yarandi)

Expression Analysis of Rice Defense-Related Genes in Turfgrass in Response to Magnaporthe grisea.

ABSTRACT Magnaporthe grisea (anamorph = Pyricularia grisea) causes blast on rice (Oryza sativa) and gray leaf spot on turfgrass. Gray leaf spot is a serious disease on St. Augustinegrass (Stenotaphrum secundatum), perennial ryegrass (Lolium perenne), and tall fescue (Festuca arundinacea). Virulence assays performed in this study revealed that M. grisea collected from rice could also cause disea...

Aploneura lentisci (Homoptera: Aphididae) and Its Interactions with Fungal Endophytes in Perennial Ryegrass (Lolium perenne)

Aploneura lentisci Pass. is endemic to the Mediterranean region where it is holocyclic, forming galls on its primary host, Pistacia lentiscus and alternating over a 2-year period between Pistacia and secondary hosts, principally species of Gramineae. This aphid is widely distributed in Australia and New Zealand on the roots of the common forage grasses, ryegrass (Lolium spp.) and tall fescue (S...
