Sensitivity of Bedding Plants to Southern Root-knot Nematode, Meloidogyne incognita Race 3.
Thirty-two cultivars of 10 commonly-grown bedding plants, representing eight families, were evaluated for their response to infection by the root-knot nematode, Meloidogyne incognita race 3, under greenhouse conditions. Four ageratum cultivars, two marigold, and two salvia cultivars were rated resistant after exposure for 8 weeks. Four begonia, four celosia, one dianthus, one verbena, one vinca...
متن کاملGreen Nanoparticles Engineering on Root-knot Nematode Infecting Eggplant plants and Their Effect on Plant DNA Modification
Background: Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards.Objectives: Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Fureth...
متن کاملConditioning Treatments Affect Insect and Mite Populations on Bedding Plants in the Greenhouse
During greenhouse production in Spring 1995, conditioning treatments were applied to columbine (Aquilegia ×hybrida Sims ‘McKana Giants’), New Guinea impatiens (Impatiens hawkeri Bull. ‘Antares’), marigold (Tagetes erecta L. ‘Little Devil Mix’) and ageratum (Ageratum houstonianum Mill. ‘Blue Puffs’) plants. Treatments included: mechanical conditioning (brushing 40 strokes twice daily); moisture ...
متن کاملNematode pathogenesis and resistance in plants.
Nematodes comprise a large phylum of animals that includes plant and animal parasites as well as many free-living species (Maggenti, 1981). Plant parasitic nematodes are obligate parasites, obtaining nutrition only from the cytoplasm of living plant cells. These tiny roundworms (generally 4 mm long and barely visible to the human eye) damage food and fiber crops throughout the world and cause b...
متن کاملNematode resistance in plants: the battle underground.
Parasitic nematodes infect thousands of plant species, but some plants harbor specific resistance genes that defend against these pests. Several nematode resistance genes have been cloned in plants, and most resemble other plant resistance genes. Nematode resistance is generally characterized by host plant cell death near or at the feeding site of the endoparasitic worm. The timing and localiza...
