Obviously, this will help to reduce their numbers. Utilize this area of the garden to grow nematode resistant crops instead such as nematode resistant tomatoes.Ĭonditioning the garden and creating a healthy tilth will go a long way to foster beneficial insects and bacteria that naturally prey on nematodes. Do not plant okra in the same area of the garden for a couple of years. Okra Root Knot Nematode Managementįor the home gardener, a combination of control methods should help control root knot nematode populations. Later in the growing season, roots may begin to rot.
The infected roots are stunted and lack fine feeder roots. Infected roots swell at the infected site and form galls. These are the just the above ground symptoms.īelow ground, the tell-tale symptoms of an okra with root knot nematodes is unveiled. This leaves a plant that is stunted and wilting, with chlorotic or pale green leaves and eventual reduced yields. Basically, when the nematode feasts on the plant roots, it interrupts the flow of nutrients and water the plant can absorb. Unfortunately for okra enthusiasts, okra is particularly susceptible to okra root knot nematodes. Usually, a healthy balance of fungus, insects, and other predatory insects keep the nematodes in check, but sometimes things are out of balance and the scale shifts. When their numbers are nominal, nematodes rarely do much damage, although the injury made from their feeding can act as a portal to disease. While most are harmless and break down organic matter or control pests, some suck juices from plant roots. Nematodes are commonly referred to as eelworms and are essential to the harmonic makeup of soil. What are root knot nematodes and how can root knot nematodes on okra be managed? About Nematode Okra Problems Okra with root knot nematodes can cause serious economic losses for commercial growers and for the home gardener, nematode okra problems may be less costly but just as challenging.
Southern Americans are not the only ones who love their okra okra root knot nematodes have a penchant for it as well. Okra, a favorite vegetable in the southeastern part of the U.S., has a multitude of culinary uses and can be steamed, fried, roasted, sautéed, etc.
