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...

Fumigation for nematode management in irrigated potato production systems of Idaho is widely practiced. Soil injection is the only labeled application method for 1,3-dichloropropene that is conventionally applied on a whole-field basis. Plant-parasitic nematode species exhibit spatially variable population densities that provide an opportunity to practice site-specific fumigation to reduce chem...

Excessive pig manure application probably degrades arable soil quality in some intensive pig farming areas. The responses of the nematode community to dosages of pig manure were investigated in Ferric Acrisols under 3-season peanut monoculture. Varying dosages of manure (1.75, 3.5, 7, 14 and 28 t·ha-1·yr-1) in combination with chemical fertilizer were applied to field plots, and chemical fertil...

The effects of the non-fumigant nematicide imicyafos on soil nematode community structure and damage to radish caused by Pratylenchus penetrans were evaluated in two field experiments in consecutive years (2007 and 2008). Nematode densities in soil at 0 10 cm (the depth of nematicide incorporation) and 10 30 cm were measured. The application of imicyafos had a significant impact on the density ...

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 southern root-knot nematode, Meloidogyne incognita, is the most damaging pathogen of cotton in the United States, and both resistance and tolerance to M. incognita could be valuable management approaches. Our objectives were to evaluate advanced cotton breeding lines for resistance and tolerance to M. incognita and to determine if a relationship between resistance and tolerance exists. Repr...
