[Terry Kirkpatrick – Division of Agriculture Nematologist] If a field has a major root-knot nematode problem, then managing that is going be probably the most difficult of all the nematodes because root-knot has the broadest host range. [Picture of Root-Knot Nematodes – Slide – Most difficult to control; Broadest host range.] If you take a root-knot field and grow corn, or susceptible, root know susceptible soybean, or cotton, you’re going tend to aggravate the problem even more, you’ll increase the population because all three of these are very suitable hosts. The following crop then, if it’s root-knot susceptible, may be damaged severely. [Slide – Increase Root-Knot – Corn; susceptible soybean; cotton.]
[Picture of a flooded rice field.] Now rice is not a host for the root-knot nematode and certainly the flooded culture that we use in paddy rice also helps.
