Pasteuria penetrans for Control of Meloidogyne incognita on Tomato and Cucumber, and M. arenaria on Snapdragon.
Meloidogyne incognita and Meloidogyne arenaria are important parasitic nematodes of vegetable and ornamental crops. Microplot and greenhouse experiments were conducted to test commercial formulations of the biocontrol agent Pasteuria penetrans for control of M. incognita on tomato and cucumber and M. arenaria on snapdragon. Three methods of application for P. penetrans were assessed including s...
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 کاملPasteuria sp. Parasitizing Trophonema okamotoi in Florida.
Two populations of Trophonema okamotoi parasitized by Pasteuria sp. were found on Liquidambar styraciflua (sweetgum) and on an unidentified tropical grass in north-central Florida. Endospores of this Pasteuria sp. attached to motile vermiform second-stage juveniles (J2) and males of T. okamotoi, but not to other developmental stages. Sporangia and new endospores were produced only inside the bo...
متن کاملBiological Control of Meloidogyne incognita by Paecilomyces lilacinus and Pasteuria penetrans.
The root-knot nematode Meloidogyne incognita was controlled more effectively and yields of host plants were greater when Paecilomyces lilacinus and Pasteuria penetrans were applied together in field microplots than when either was applied alone. Yields of winter vetch from microplots inoculated with the nematode and with both organisms were not statistically different from yields from uninocula...
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...
