Abstract:
The project is divided into the following major tasks: 1) the production and analyses of plant material, plant
extracts for screening for nematicidal activities (plant material selected on the basis of previous research and ease
of production of material [plant growth and cost of production]), 2) the development of robust in vitro bioassays
for soil-borne and aerial nematodes and evaluation of soil properties on phytochemical effectiveness, 3) doseresponse studies for the four nematode species (Globodera, Heterodera, Meloidogyne, and Bursaphelenchus
xylophilus) with crude plant material and various fractions from the selected plant species (single extracts and
synergism studies), 4) modeling the data for correlating dose-response curves and extrapolation to field
conditions, 5) combining all the results for evaluating the effectiveness of the different phytochemicals and
development of an effective nematicide. It is expected that at the end of the research species-specific natural
nematicides, and possibly a multi-species nematicide, based on phytochemicals from either single plant species or
a combination of the species for maximal nematicidal activity, will have been identified.
