DOUDA O. (2005): Host range and growth of Stem and Bulb Nematode (Ditylenchus dipsaci) populations isolated from garlic and chicory. Plant Protect. Sci., 41: 104–108. Host range and growth of two Ditylenchus dipsaci (Stem and Bulb Nematode) populations on onion, garlic, leek, spinach and chicory were compared. Inoculation was conducted by placing a droplet of 1.5% CMC suspension containing nema...
متن کاملParasitism of Nonhost Cultivars by Ditylenchus dipsaci.
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.
متن کاملWater loss and morphological changes during desiccation of the anhydrobiotic nematode Ditylenchus dipsaci
Ditylenchus dipsaci is an anhydrobiotic nematode which can withstand direct exposure to extreme desiccation. Water loss has been determined gravimetrically and morphological changes quantified by light microscopy. Water loss occurs in two distinct phases, with a permeability slump 2 min after the onset of desiccation. The permeability slump remains after treatment with sodium azide or carbon di...
متن کاملFactors affecting the infection of alfalfa seedlings by Ditylenchus dipsaci.
Experiments were conducted to determine the effects of plant confinement, soil type, watering practices, stage of seed germination, inoculum level, and method of applying inoculum on stem nematode (Ditylenchus dipsaci) infection of alfalfa (Medicago sativa) seedlings grown in soil. Results indicated that (i) confining seedlings together with the nematodes in small vials offered no advantage ove...
