Distribution and Damage Caused by Root-Knot Nematodes on Soybean in Southwest Indiana

G. R. Kruger, L. Xing, J. B. Santini, and A. Westphal

October 2007


In the US and Ontario, over 93,000 metric tons of soybean were lost annually from 1999 to 2002 due to Meloidogyne spp., mostly M. incognita, M. hapla, M. arenaria, and M. javanica. In southwestern Indiana, crop rotations often include watermelon, soybean, and corn, all hosts for M. incognita. In this study, the distribution of Meloidogyne spp. in southwestern Indiana was determined in a county-wide survey in 2 counties and at 2 farm operations with a history of Meloidogyne infestation.
