Root-knob nematodes

tx_ag_95(7/8 Lewisville)September 30, 2012

When I pulled up my okra today I found icky-nasty-knotted roots. Google pretty much confirmed my fear: nematodes. The black-eyed peas in the same bed didn't have the knots on their roots, but the roots seemed stunted. For that matter, all of the plants in the bed seemed stunted, I didn't get near as much "fruit" as I'd expected this summer.

The bed was essentially fallow for over a year prior to the planting in late May/early June of the okra seedlings and pea seeds. I tried to plant radish seeds last fall but they didn't do anything. I blamed it on "not enough water" because I frequently forgot to water them and there wasn't a soaker hose.

I want to plant my fall/winter seeds ASAP, but one of them is beets and they're highly susceptible to the nematodes. The rest are greens, radishes, and leeks. I MIGHT try to find some turnip seeds, too.

What advice do y'all have? I'd rather stick the seed packages in the fridge until January/February and do whatever I have to do to kill those icky bugs than plant the seeds and not get anything much.

I'm a little bit north of Dallas.

I seem to remember that there are winter cover crops that address root knot nematodes. Cereal rye is the one I've used, but there may be others.

When I lived in DFW I bought it at Marshall Grain feed store. They called it elbon or cereal rye. Native American Seed sells it online, as does Sustainable Seed Company; there might be other sources as well.

So, Northaven Gardens recommends beneficial nematodes, but they'll take a couple of months to kill off the bad nematodes. So, I guess I'm sticking the seed packages in the fridge and waiting out the fall/winter crop.... :( I don't have enough pots OR potting soil to make a decent fall/winter crop. Maybe the Winter/Spring crop will make up for it????
