Parasitism of Nonhost Cultivars by Ditylenchus dipsaci |
|
| Authors: | G D Griffin |
| Abstract: | The alfalfa race of Ditylenchus dipsaci parasitized and caused characteristic symptoms on nonhost seedlings of sweet clover, onion, tomato, sugarbeet, and wheat in controlled growth-chamber studies. Although the nematode was unable to reproduce on any of the cultivars, it caused plant mortality ranging from 20% on sugarbeet and tomato to 100% on onion. |
