Effect of Southern Root-knot Nematode (<i>Meloidogyne incognita</i> race 3) on Corn Yields in Alabama

Fig. 4. Populations of Meloidogyne incognita race 3 (2nd-stage juveniles/100 cm³ of soil) in late summer and corresponding yields of corn in subsequent year. Lines indicate regression models for determining loss estimates. Second-stage juvenile counts from plots planted to peanut are green, cotton are blue, and corn are red.
