NEW OR UNCOMMON PLANT DISEASES AND PESTS.

This article looks at the two plant diseases and pests. Root-knot eelworm was recorded on several crops in eastern England. Meloidogyne artiellia has been described from oats and other crops but not from the grasses. In 1952, females of a Meloidognye species differing in some respects from the described species were found in small galls on the roots of Lolium multiflorumLam. undersown in an oat crop near Swansea, Wales. The Rose Line Pattern is considered to be a form of Rose Mosaic. Clearly defined wavy yellow bands were present on the young red leaves, sometimes conforming to an oak-leaf pattern. Quite often the line marking was confined to a strip across the distal end of the leaf.
