Reproduction of Pratylenchus penetrans on Potato and Crops Grown in Rotation with Potato.
The relative suitability of potato and crops frequently grown in rotation with potato as hosts for Pratylenchus penetrans was evaluated. Suitability of rye, wheat, corn, oat, sorgho-sudangrass, and potato were compared in pot studies based on ratios of final population : initial population density and densities of nematodes in roots at harvest. Population densities increased more on potato, oat...
متن کاملEffects of Temperature on Pratylenchus neglectus and on Its Pathogenicity to Barley.
In a petri-dish study, development of the nematode Pratylenchus neglectus was observed every 4 days, and stage-specific development times were estimated, using a parameter estimation algorithm for a distributed-delay population model. The lower threshold temperature for development of a population of P. neglectus was 7.75 C. Temperatures above 25 C were unfavorable for this population on barley...
متن کاملBiology and Pathogenicity of Pratylenchus neglectus on Alfalfa.
Pratylenchus neglectus reduced the growth of alfalfa cultivars in greenhouse and growth chamber studies. Inocula (1,000, 5,000 and 10,000 nematodes per plant) reduced shoot dry weights of Ranger by 16, 27, and 40%, of Lahontan by 16, 32, and 40%, and of Nevada Synthetic XX (Nev Syn XX) by 18, 26, and 37%, respectively, at 26 ñ 2 C. Pratylenchus neglectus at 1,000 nematodes per plant reduced Ran...
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...
