Control of Root-knot Nematodes on Tomato by Lectins.
Significant control of tomato root knot was achieved by applications of the lectins Concanavalin A (Con A) and Limax flavus agglutinin in greenhouse, growth chamber, and microplot trials. Four
In vitro sensitivity of Meloidogyne incognita to extracts from native Yucatecan plants.
In vitro nematicidal assay showed that extracts from Calea urticifolia leaves and roots, Eugenia winzerlingii leaves, and Tephrosia cinerea stems were the most active against M. incognita.
Mexican periwinkle virescence phytoplasma associated with phyllody and virescence in strawberry (Fragaria x ananassa Duch.) in Michoacan, Mexico
This report is the first to describe this phytoplasma in strawberry in Mexico in the municipalities of Zamora, Jacona, Tangancícuaro, Chilchota and Maravatio in the state of Michoacan and to design strategies for managing the disease in commercial nurseries and commercial plantings.
Evaluation of control of Meloidogyne incognita and Nacobbus aberrans on tomato by two leguminous plants.
SUMMARY When the leguminous plant Concanavalia enszformis and tomato were cocultivated in greenhouse pot tests, a reduction in galling caused by Meloidogyne incognita and Nacobbus aberrans was
Nematophagous Fungi from Agricultural Soils of Central America
Seventeen agricultural soils from Costa Rica, Nicaragua and Panama were surveyed for fungi attacking vermiform nematodes and 13 species of nematode-trapping fungi were found. The most commonly
Behavioral Effects of Carbofuran and Phenamiphos on Pratylenchus vulnus. I. Motility and Dispersion.
The motility and dispersion of Pratylenchus vulnus was affected by lower concentrations of phenanliphos (an organophosphate) than of carbofuran (a carbamate). At the higher concentrations in the
Fluorescent and Ferritin Labelling of Cuticle Surface Carbohydrates of Caenorhabditis elegans and Panagrellus redivivus.
Rhodamine-labelled peanut agglutinin and Limax flavus agglUTinin did not label nematodes of either species, whereas mannose-glucose residues were specifically localized in the head areas of both species.
Surface Carbohydrates of Plant Parasitic Nematodes
After blocking experiments with appropriate complementary sugars, N-acetylglucosamine residues were found on the head, amphids or amphidial exudates of A. avenae and appeared as non-specific labelling in lipid droplets.
