Reproduction of Pratylenchus penetrans on 24 Common Weeds in Potato Fields in Québec.
Twenty-four weeds commonly found in commercial potato fields in Quebec were evaluated for their host suitability to the root-lesion nematode, Pratylenchus penetrans, under greenhouse conditions. Brown mustard (Brassica juncea) and rye (Secale cereale) were included as susceptible controls and forage pearl millet hyb. CFPM 101 (Pennisetum glaucum) as a poor host. Pratylenchus penetrans multiplie...
متن کاملHost Suitability of Commercial Sunflower Hybrids to Pratylenchus zeae.
Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...
متن کاملInterpreting Upland Rice Yield and Pratylenchus zeae Relationships: Correspondence Analyses.
Correspondence analyses were used to explore the relationships between yield and populations of Pratylenchus zeae in an upland rice field and in a greenhouse experiment. Initial soil (Pi) and final root (Pf) population densities of P. zeae, and yield (Y) of rice cv. UPL Ri5 were determined at 490 spots in the field. Very low Y was linked to very high Pf. Low Y was linked to medium or high Pi an...
متن کاملEffect of Temperature on Reproduction and Motility of Pratylenchus vulnus.
Reproduct ion of Pratylenchus vulnus Allen and Jensen on rose was repor ted faster at 32.2 C than at 23.9 and 15.6 C (6). Reproduct ion on alfalfa tissue was faster at 25 C than at 20 and 30 C (3), while on 'Lovell ' peach and bush bean, reproduct ion was faster at 28.3 C than at 24.4, 20.6, 16.7, and 12.8 C (1). Populat ions of P. vulnus and other species of root-lesion nematodes are often rai...
متن کاملEffects of Pratylenchus zeae and Quinisulcius acutus Alone and in Combination on Sorghum.
Host-parasite relationships of Pratylenchus zeae and Quinisulcius acutus, alone or in combination, were studied on sorghum in the greenhouse and laboratory. Q. acutus at 1,000 or 5,000 nematodes per 15-cm-d pot and P. zeae at 500 nematodes per pot significantly suppressed plant height and fresh and oven dry shoot and root weights. A mixture of 1,000 Q. acutus and 500 P. zeae per pot resulted in...
