Pathogenicity of Criconemella curvata to Alfalfa.
نویسندگان
چکیده
Large populations of Criconemella curvata and extended experimental periods were required to adversely affect yield of 'Moapa 69' alfalfa. C. curvata ectoparasitic feeding caused a reduction in feeder root numbers and tap root size and small lesions on tap and secondary roots. Greater reproduction occurred at 27 C than at 22 C, but the effect of the nematode on alfalfa growth was the same at both temperatures.

Cuticle Ultrastructure of Criconemella curvata and Criconemella sphaerocephala (Nemata: Criconematidae).
Cuticle ultrastructure of Criconemella curvata and C. sphaerocephala females is presented; males were available only in the second species. Ultrathin sections revealed three major zones: cortical, median, and basal. The cortical zone in the females consists of an external and internal layer. In C. curvata the external layer is trilaminate and at each annule it is covered by a multilayered cap. ...
متن کاملVertical distribution of three nematode genera in a bentgrass putting green in central illinois.
A study was conducted to determine the vertical distribution of Tylenchorhynchus nudus, Criconemella curvata, and Helicotylynchus cornurus in the upper 5 cm of bentgrass (Agrostis palustris cv. Penncross) putting green turf. The effect of fenamiphos on the vertical distribution of these species also was examined. Experimental design was a split-plot in which whole-plots were fenamiphos treated ...
متن کاملNematodes associated with blackberry in arkansas.
A survey of the nematodes in blackberry (Rubus sp.) rhizospheres was conducted in Arkansas from 1986 to 1989. The state was divided arbitrarily into four quadrants. A total of 134 soil samples was collected, and 150-cm 3 subsamples were assayed for nematodes. Twenty-one species of plant-parasitic nematodes in 11 genera were extracted from the samples. There were differences (P = 0.05) among qua...
متن کاملPathogenicity of Two Populations of Meloidogyne hapla Chitwood on Alfalfa and Sainfoin.
The pathogenicity of two populations of the northern root-knot nematode, Meloidogyne hapla Chitwood, population 1 (P1) from alfalfa and population 2 (P2) from sainfoin, was studied on both alfalfa and sainfoin for 25 weeks. Alfalfa and sainfoin plants inoculated with P2 had significantly (P </= 0.05) higher mortality than plants inoculated with P1. Plant stands over all weeks for the uninoculat...
متن کاملEffects of temperature on the pathogenicity of Tylenchorhynchus clarus to alfalfa and observations on feeding.
The involvement of Tylenchorhynchus clarus in plant disease is reported. Addition of a suspension of surface-axenized nematodes reduced top and root growth of alfalfa. Reproduction of T. clarus was greater at 24 and 27 than at 21 C. The interaction of nematodes with temperature did not produce significant effects on alfalfa growth in the 4.5-mo experimental period. T. clarus fed endo- and ectop...
