Pratylenchus penetrans Population Dynamics on Three Potato Cultivars.
Reproduction of Pratylenchus penetrans on the potato cultivars Hudson, Katahdin, and Superior was determined in greenhouse and field microplot experiments. Although all three cultivars were good hosts for P. penetrans, differences in reproductive rate were found. In one greenhouse experiment, Katahdin plants inoculated with 1,500 or 15,000 P. penetrans per pot had larger population densities at...
متن کاملRelative susceptibility of selected cultivars, of potato to Pratylenchus penetrans.
Pratylenchus penetrans suppressed the tuber yields of potato cultivars 'Katahdin', 'Kennebec', and 'Superior', but did not affect yields of 'Russet Burbank'. In comparison with noninfested controls, all initial nematode densities (P(i)) of P. penetrans (P(i) = 38, 81, 164, 211/ 100 cm(3) of soil) suppressed yields of Superior; a moderate P(i) (81/100 cm(3) soil) suppressed yields of Kennebec; a...
متن کاملEffect and Reproduction of Rotylenchulus reniformis on Sweet Potato Selections.
Growth, yield, and quality of 10 sweet potato selections and reproduction of the reniform nematode, Rotylenchulus reniformis, were studied in fumigated and nonfumigated plots in a naturally infested field. Nematode reproduction on the different selections in the field was similar to that reported in the greenhouse but was not related to the effect of the nematode on yield of the different selec...
متن کاملReproduction 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 کاملCitrus Tree Decline Caused by Pratylenchus coffeae.
The pathogenic effects of Pratylenchus coffeae on growth and yield of tangelo (Citrus paradisi x C. reticulata) scions grafted on rough lemon (C jambhiri), sour orange (C. aurantium) and 'Cleopatra' mandarin (C. reticulata) rootstocks were evaluated under field conditions for 4 years. Pratylenchus coffeae on inoculated trees increased to significantly damaging population densities on rough lemo...
