Importance
The genus Pratylenchus is considered one of the most important among plant-parasitic nematodes because of its wide range of hosts and worldwide distribution. They may reduce root growth or inhibit root development by forming local lesions on young roots. The lesions may also lead to secondary infections by fungi or bacteria, increasing the plant's susceptibility. The overall root damage associated with Pratylenchus can cause poor growth, reduce crop yields, or kill off the plant completely. These nematodes hold economic importance if crop loss is drastic and profits decrease.

Famous quotes containing the word importance:
“Society is the stage on which manners are shown; novels are the literature. Novels are the journal or record of manners; and the new importance of these books derives from the fact, that the novelist begins to penetrate the surface, and treat this part of life more worthily.”
—Ralph Waldo Emerson (1803–1882)
“The importance of its hat to a form becomes
More definite. The sweeping brim of the hat
Makes of the form Most Merciful Capitan,
If the observer says so....”
—Wallace Stevens (1879–1955)
“There are of course people who are more important than others in that they have more importance in the world but this is not essential and it ceases to be. I have no sense of difference in this respect because every human being comprises the combination form.”
—Gertrude Stein (1874–1946)
