NETTLEHEAD IN HOPS

SUMMARY Under the name “Nettlehead” two quite distinct diseases, “true” and “false,” have been noticed. In the case of “False” Nettlehead the bine usually dies away in August and the root system is in a state of decay; in the “True” form the bine remains green though growth is retarded, at the same time the root system remains in an apparently healthy state. The “True” form is usually to be found starting from the edge of a garden especially where the garden slopes down to a deep ditch or high hedge. “Fahe” Nettlehead, on the other hand, may be found distributed throughout the garden. The Beet eelworm, Heterodera Schachtii, may be found in all hop gardens, but its presence is not correlated with “Nettlehead.” “True” Nettlehead has been in greater evidence the year following a bad attack of aphis.
