Project Number: 6402-42000-004-01
Start Date: Jan 01, 2007
End Date: Dec 31, 2010
Field and greenhouse studies will be used to evaluate variety resistance to damage caused by M. phaseolina. Replicated field and greenhouse trails will be established at Starkville and Stoneville using two different varieties comparing select Ca treatments (rates, forms and timing) to determine if 1) improved uptake occurred in the plants and 2) monitor toxin production and disease development. Fields will be selected with a known history of M. phaseolina occurrence. Samples of plant tissues with charcoal rot disease will be obtained from a wide variety of sources, as well as samples of soil from fields where the disease is found in the U.S.
