Effect of Ditylenchus dipsaci on Alfalfa Mortality, Winterkill, and Yield.
Ditylenchus dipsaci-infected and noninfected alfalfa plants in a naturally infested field were studied from July 1980 to September 1982. Forty-one percent of the plants died during the study. Ninety-seven percent of the plants that died were infected with D. dipsaci. Sixty-nine percent of the observed mortality occurred during winter. Forage yield of infected plants was significantly lower than...
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...
متن کاملInterrelationship of Meloidogyne hapla and Ditylenchus dipsaci on Resistant and Susceptible Alfalfa.
Simultaneous inoculations of alfalfa with Meloidogyne hapla larvae and Ditylenchus dipsaci at 16, 20, 24, and 28 C did not depress penetration of either nematode in 'Nev Syn XX' -a selection resistant to M. hapla and D. dipsaci, 'Vernal 298' -a selection resistant to M. hapla and susceptible to D. dipsaci, 'Lahontan' -a cultivar resistant to D. dipsaci and susceptible to M. hapla, and 'Ranger' ...
متن کاملPathological Relationship of Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis on alfalfa.
Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis synergistically affected the mortality and plant growth of Ranger alfalfa, a cultivar susceptible to stem nematode and Fusarium wilt. The nematode-fungus relationship had an additive effect on mortality and plant growth of Lahontan (nematode resistant and Fusarium wilt susceptible) and of Moapa 69 (nematode susceptible and Fusarium w...
متن کاملEffect of Acclimation Temperature on Infection of Alfalfa by Ditylenchus dipsaci.
Ditylenchus dipsaci showed an affinity, in relation to infection, for the temp at which it had been acclimated. The optimum infective temp was also correlated with field temp when collections were made during different seasons and from climatically different geographical areas. Nematode developmental stage did not influence infectivity.
