Non-infested plots, with no proof of pathogenicity attributable to nematode

The NemOut treatment options (0 and 336 g/ha) had been applied using a surfactant to a trench within the center of the pots. A single cotton seed was planted in the center of the trench plus the trench cover with soil; the plants had been for the tagged protein {in the|within inoculated with J2 of M. incognita two wks later. The experiment was carried out two occasions with seven replications per therapy. Nematode reproduction was assessed 60 days just after inoculation. Percentage suppression of nematode reproduction by P. lilacinus was higher when the residue was placed on the soil surface than when it was removed. Nematode suppression inside the presence of residue was 60 for rye and 49 for clover compared to 35 in fallow soil. In the absence of residue, nematode suppression was reduced inside the cover crop treatments than within the fallow soil. In conclusion, suppression of M. incognita by P. lilacinus was improved when a cover crop was grown just before cotton; however, this was accurate only when the above-ground residue was left around the soil surface. INHERITANCE OF RESISTANCE TO MELOIDOGYNE JAVANICA ROOT-GALLING Inside a BRAZILIAN SOYBEAN. Vinholes, Patricia da Silva1,two, V.M.P. Silva3, T. Dalla Nora3, I. Schuster3, A. Borem2, and P.A. Roberts1. 1Departament of Nematology, University of California, Riverside, Riverside, CA, 92521; 2Department of Plant Science, University of Vicosa, Vicosa, MG/Brazil; and 3Cooperativa Central de O see him so miserable, have arranged a private assessment {with Pesquisa Agricola, Cascavel, PR/Brazil. In Brazil, root-knot nematode Meloidogyne javanica causes serious yield loss of soybean [Glycine max (L.) Merril] in lots of agricultural places. An effective approach to stop yield loss is planting root-knot nematode resistant cultivars. However, Brazilian cultivars have narrow genetic base for resistance to root-knot nematode, derived in the cultivar Bragg. Inheritance of resistance to Meloidogyne javanica (Mj) induced root-galling in cv.Non-infested plots, with no proof of pathogenicity attributable to nematode infection or host resistance response. The use of propagated plant cuttings maintains direct linkage in between initial screening outcomes for resistance to M. incognita as well as the deployment of such traits inside time frames as quick as two years. SUPPRESSION OF MELOIDOGYNE INCOGNITA BY PAECILOMYCES LILACINUS IS ENHANCED BY PLANTING COVER CROPS. Timper, Patricia1 and G. Parajuli2. 1USDA ARS, P.O. Box 748, Tifton, GA 31793; and 2Wageningen University and Study Center, 6708 PB Wageningen, The Netherlands. Paecilomyces lilacinus is actually a common soil saprophyte and some strains of this fungus are aggressive parasites of sedentary stages of nematodes. The fungus is registered within the U.S. beneath the trade names MeloCon WG and NemOut. Persistence of P. lilacinus is comparatively low in sandy soils compared to other soil types. Addition of organic matter to sandy soil was shownMeeting Abstracts 495 to increase persistence of the fungus. In conventional agriculture, winter cover crops are made use of to cut down soil erosion and loss of plant nutrients. We hypothesized that, compared to fallow soil, expanding a cover crop ahead of application of P. lilacinus would raise efficacy from the fungus against Meloidogyne incognita on cotton. A greenhouse experiment was conducted in which cover crops were grown for 1 month, killed with herbicides, plus the above-ground residue cut and left around the soil surface or removed.
