Recent advances in precision agriculture technologies and spatial statistics allow realistic, site-specific estimation of nematode damage to field crops and provide a platform for the site-specific delivery of nematicides within individual fields. This paper reviews the spatial statistical techniques that model correlations among neighboring observations and develop a spatial economic analysis ...

Crop rotation is one of the oldest and most important approaches to the con­ trol of nematodes that feed on the roots of annual crop plants. The value of rotations often was recognized long before their effects upon the dynamics of nematode populations and communities were considered. As specific nema­ tode problems were identified and their economic importance demonstrated, attention usually w...

Integrated fruit production (IFP) offers an alternative to the chemically intensive, conventional pear production system. In 1994, we began a 4-year project supported by the Hood River Grower Shipper Association (HRGSA) together with Oregon's Center for Applied Agricultural Research (CAAR) to demonstrate to the industry how to bring about changes in orchard management practices, particularly as...

Background: Chickpea (Cicer arietinum) is one of the most important food legumes grown worldwide. Its cultivation in India hampered considerably due to regular occurrence root knot nematode and reported reduce chickpea yield by 9-40%. Methods: The present study was conducted evaluate some germplasm for resistance against nematode, Meloidogyne incognita. field experiment also management root-kno...

The concept of utilizing organic amendments to manage plant-parasitic nematodes is not new, but the widespread implementation of this management practice has still not been realized. The use of organic amendments for plant-parasitic nematode management is a complex process requiring an understanding of the transformation and generation of active compounds. As a result, research endeavors to und...

among fungi, species of the genus paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (rkn) and other nematode populations. in this research we investigated a soil hyphomycetes, paecilomyces marquandii and its pathogenicity on eggs of rkn in vitro. in greenhouse test, root weight, plant length, fresh weight and dry weight of plants...

Seasonal density of trichostrongylid nematode larvae was investigated on a pasture used for communal grazing of livestock, using standard procedure of pasture larval count. For this purpose, herbage samples were collected from a posture near Faisalabad at fortnightly intervals over a 12 month period from July 2000 to June 2001. The larvae of Haemonchus (H) contortus, Trichostrongylus species, O...

Meloidogyne incognita-infected and noninfected tubers of yellow nutsedge (Cyperus esculentus) and purple nutsedge (Cyperus rotundus) were treated with 56 L/ha 1,3-dichloropropene (1,3-D) in microplots and subsequently examined for tuber and nematode viability in the greenhouse using a chile pepper (Capsicum annuum) bioassay system. The study was conducted three times. Nutsedge tuber viability a...

The helminths of the following red duikers, Cephalophus natalensis, were examined: 24 from 3 game reserves in Natal and 1 that had originated from Charters Creek, Natal, shortly before it died in the National Zoological Gardens, Pretoria. The 21 animals from Charters Creek harboured 16 nematode species, a nematode genus, 2 cestode species and paramphistomes. The 2 red duiker from Fanies Island ...
