The Effects of European corn borer on whole-plant yieldand root knot nematode fitness in corn
… European corn borer and belowground herbivory by root knot nematode, Meloidogyne incognita Chitwood (Tylenchida: Heteroderidae), in corn. Two experiments were conducted to measure belowground herbivory by M. incognita in juvenile penetrations and eggs/root system. In the first experiment, the main …

Reproduction of the root-knot nematode Meloidogyne arenaria on flue-cured tobacco possessing resistance genes Rk1 and/or Rk2 and the impact of parasitism on the accumulation of nicotine in conventional and low-alkaloid tobacco
… of flue-cured tobacco in regions where root-knot nematodes present a threat to growers. Resistance to races 1 and 3 of M. incognita, historically the most significant root-knot nematode threat to tobacco production, is now widely available in commercially available flue-cured tobacco …

Reproduction of a root-knot nematode population on flue-cured tobacco homozygous for Rk1 and/or Rk2 resistance genes and the effect of soil temperature on resistance gene efficacy
… cultivars is a main control strategy for root-knot nematodes in flue-cured tobacco (Nicotiana tabacum L.). Most commercial cultivars possess the Rk1 gene, providing resistance to races 1 and 3 of Meloidogyne incognita and race 1 of M. arenaria. This initiated a shift in root-knot …

Perennial Grass Based Crop Rotations in Virginia: Effects on Soil Quality, Disease Incidence, and Cotton and Peanut Growth
… quality. Soilborne plant pathogens including root-knot nematode, stubby root nematode, ring nematode, stunt nematode, and Cylindrocladium parasiticum microsclerotia were measured in the spring and fall of each year to determine differences associated with crop rotations. Water stable soil …

Managing Weeds and Soilborne Pests with Fumigant and Non-Fumigant Alternatives to Methyl Bromide
… control in tomato. Grafting onto resistant rootstocks was tested for bacterial wilt and nematode management in tomato. In the absence of a soil fumigant, TIF suppressed yellow nutsedge better than VIF. TIF increased fumigant retention compared to VIF at similar application rates. Reduced …

Effects of Increased Atmospheric Carbon Dioxide Levels on Tobacco Mosaic Virus and Root-Knot Nematodes in Genetically Resistant and Susceptible Tomato Plants
… on the effects of elevated CO<sub>2</sub> on Root-Knot Nematode (<em>Meloidogyne arenaria</em>) and Tobacco Mosaic Virus (TMV) infection in genetically resistant versus susceptible tomatoes (<em>Solanum lycopersicum</em>). Both resistant and susceptible tomatoes were grown in chambers with …

Phytochemistry in the development of pesticides and biocides
… for the nematicidal properties against the root knot nematode Meloidogyne spp., in the form of pastes and extracts for soil amendment as well as plant secondary metabolites isolated from the afore mentioned matrixes and used individually or in binary mixtures to create synergism. The effects …

Nematicidal, antimicrobial and acaricidal activity of plant secondary metabolites
… polyphenols as potential nematicidal against the root knot nematode Meloidogyne spp. We deal also about the possible mode of action of aromatic aldehydes by the inhibition of V-ATPase of the nematode. Second, we demostrate the antimicrobial activity of carob (Ceratonia siliqua) against Listeria …

An investigation into the potential of crude and partially separated material of selected non–crop plant species as control agents of root–knot nematodes (Meloidogyne incognita) in tomato
Plant-parasitic nematodes (PPN) are a serious problem in vegetable production and can cause severe damage to several crops. In rural, low-input farming nematode damage is much higher and yields can be completely destroyed. Some Commercial nematicides have been withdrawn from the market due to …

The development of gene silencing strategies for plant parasitic nematodes
… in two economically important plant parasitic nematodes (PRNs), the potato cyst nematode Globodera pallida and the root knot nematode Meloidogyne incognita. Much of the work contributing to this project has advanced our understanding of RNAi in these nematodes, and may also have broader …

Characteristics of biological control agents and their antagonism against rice pathogens and pests
… may cause significant yield loss such as rice root-knot nematodes, bacterial leaf blight, and brown planthopper. Currently, pesticide use is the dominant practice for pest and disease management in Asian rice farming. The use of beneficial microbial agents for the control of pathogens and pests …

Effects on nematodes produced by certain types of electrical energies
… concerning the effects of electricity on nematodes, was conducted in order to find a method of controlling the root-knot nematode in the tobacco field by the use of electricity. The output of a simple induction coil (p. 13 and 37), a 220 Volt 60 cycle current (p. 44), and a 27.12 megacycle …
