Perla, David E. M.S., Purdue University, August, 2014. Management of Root Knot Nematode (Meloidogyne incognita) in Indiana Soybeans. Major Professors: Ricky Foster and Virginia Ferris. The aim of this project was to evaluate different strategies for management of Root Knot Nematode (RKN) on soybean and tomato in Indiana. Seed treatments were evaluated under field and greenhouse conditions, but ...

Interest in the sustainability of farming practices has increased in response to environmental problems associated with conventional agricultural management often adopted for the production of herbaceous crops, ornamentals, and fruit crops. Availability of measures of the status of the soil ecosystem is of immediate importance, particularly for environmental assessment and monitoring programs. ...

Rotylenchulus reniformis is the predominant parasitic nematode of cotton in the Mid South area of the United States. Although variable levels of infection and morphological differences have been reported for this nematode, genetic variability has been more elusive. We developed microsatellite-enriched libraries for R. reniformis, produced 1152 clones, assembled 694 contigs, detected 783 simple ...

Belonolaimus longicaudatus is an important parasite of both warm-season bermudagrass and winter overseed grasses used on golf courses in the southeastern United States. Field trials were conducted to study the effects of a commercial formulation of Paecilomyces lilacinus strain 251 applied to overseed grasses during the winter and early spring on population density of B. longicaudatus and bermu...

Plant parasitic nematodes on golf courses present special problems for both disease diagnosticians and superintendents. In contrast to fungal diseases, which are unacceptable at any level, low to moderate levels of plant parasitic nematodes should be expected in any stand of turf. The difficult part of managing a potential nematode problem is determining when the nematode population is actually...

Abstract The objective of this work was to evaluate the effects winter crops and soybean management systems on Pratylenchus brachyurus Helicotylenchus dihystera populations, in a naturally infested site, south-central region state Paraná, Brazil. experiment carried out during two crop years (2017/2018 2018/2019). Barley or black oat (winter crops) (summer crop) were treated with chemical biolog...

ABSTRACT Isothiocyanates are released through enzymatic degradation of glucosinolates produced by plants in the family Brassicaceae. Glucosinolate profiles differ among plant species and the isothiocyanate derivatives differ in their toxicity to nematodes. Control of plant-parasitic nematodes in soil by isothiocyanates released from incorporated brassicaceous plant material has been inconsisten...

Crop rotation is an effective tactic for soybean cyst nematode (SCN) management. In the North Central region of the USA, corn is almost exclusively used as a nonhost rotation crop with soybean. This study was conducted to determine the effectiveness of crops common to or having potential use in the North Central region as rotation crops for managing SCN. Sixteen potential rotation crops and SCN...

in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...
