In Vitro Evaluation of Ovicidal and Larvicidal Effects of Culture Filtrate of Verticillium chlamydosporium Against Meloidogyne javanica
Effects of culture filtrate of Verticillium chlamydosporium were evaluated on mortality of larvae and hatching of eggs of Meloidogyne javanica. Mortality of M. javanica larvae was found to be directly proportional to concentrations of culture filtrate of V. chlamydosporium and duration of exposure. Maximum mortality of larvae (65.5%) was observed in 100% concentration of culture filtrate after ...
متن کاملEffects of Fluctuating Temperatures and Different Host Plants on Development of Pasteuria penetrans in Meloidogyne javanica.
Greenhouse and growth room experiments were conducted to investigate the effect of host plant in relation to different nematode inoculum levels, and temperature fluctuations on the development of Pasteuria penetrans. Host plant affected the development of P. penetrans indirectly through its effect on nematode development. Endospores collected from Meloidogyne javanica females reared on differen...
متن کاملSuppression of Meloidogyne incognita and M. javanica by Pasteuria penetrans in Field Soil.
The role of Pasteuria penetrans in suppressing numbers of root-knot nematodes was investigated in a 7-year monocuhure of tobacco in a field naturally infested with a mixed population of Meloidogyne incognita race 1 and M. javanica. The suppressiveness of the soil was tested using four treatments: autoclaving (AC), microwaving (MW), air drying (DR), and untreated. The treated soil bioassays cons...
متن کاملAttachment of Pasteuria penetrans Endospores to the Surface of Meloidogyne javanica Second-stage Juveniles.
Pasteuria penetrans spore adhesion to Meloidogyne javanica second-stage juveniles (J2) was examined following several different pretreatments of the latter. The detergents sodium dodecyl sulfate and Triton X-100, the carbohydrates fucose and alpha-methyl-D-mannoside, and the lectins concanavalin A and wheat germ agglutinin reduced spore attachment. Spores exposed to M. javanica surface coat (SC...
متن کاملEvaluation of Verticillium chlamydosporium and Arthrobotrys oligospora for biological control of Meloidogyne incognita in celery
Aggressiveness of fifteen isolates of Phaeoisariopsis griseola and variations in angular leaf spot symptom development in common bean were studied. The isolates were selected based on their virulence and genetic differences and represented Andean, Afro-Andean and Mesoamerican groups of P. griseola. Aggressiveness was determined based on length of incubation period, rate of lesion expansion, les...
