What plants are not susceptible to nematodes?

Several plants such as broccoli, beet, Brussels sprouts, cabbage, collards, corn, English peas, garlic, mustard, onion, and potato are less susceptible to injury from root-knot nematode primarily because they are grown during cool weather when this nematode is not as active.

What vegetables are susceptible to nematodes?

Although many spring-planted vegetables such as beets, carrot, English pea, lettuce, potato, radish, and others are susceptible to root-knot nematode, they can be grown in infested soil and suffer only minor damage because nematodes are inactive at low soil temperatures (60°F).

What are nematode resistant plants?

In the home landscape, some bedding plants are resistant to root-knot nematodes including zinnia, salvia and marigold. Some damage may occur to snapdragons and pansies, especially when plants are stressed. Begonias, coleus and impatiens are most likely to be damaged in areas where root-knot nematodes are a problem.

How do I get rid of nematodes in my vegetable garden?

Remove plants and dig up the roots at the end of each growing season to remove the nematodes’ food source. Dispose of the plant matter. Till the soil after removing the plants to dry the soil and expose the nematodes to sunlight, which kills them.

Do tomatoes get nematodes?

Tomato plants can be susceptible to root-knot nematodes, which are microscopic, roundworms that inhabit the soil. Besides root-knot nematodes, there are numerous other types of non-parasitic nematodes that inhabit the soil. These non-parasitic types do not infect plants and are an important part of the soil food web.

How do cucumbers control nematodes?

Currently nematode management considerations include crop rotation of less susceptible crops or resistant varieties, cultural and tillage practices, use of transplants, and preplant nematicide treatments.

What tomatoes are nematode resistant?

Some tomato varieties you are likely to find at local nurseries that are resistant to root-knot nematodes include Celebrity, Better Boy, Better Boy Bush, Early Girl Bush and Park’s Whopper. Your local nursery may carry other varieties that are resistant; just look for that capital N after the variety name.

Do marigolds repel nematodes?

Marigolds are one of the few plants that can fight back against certain nematodes. There are only a few plants that have been found to produce substances known to be detrimental to nematodes.

Do pepper plants get nematodes?

Root knot and stubby root nematodes are the most serious nematode parasites on bell peppers in California. Heavy infestations of root knot nematodes can cause significant reduction in crop stand, and growth and yield of plants.

How do you treat tomatoes for nematodes?

Other options include adding valuable organic matter that helps support your tomatoes, using soil solarization to kill the nematodes with heat, or fallowing the garden and rototilling it every two weeks to prevent weed establishment.

How do I get rid of nematodes in my yard?

No chemicals available to homeowners kill nematodes in planted soil. Soil fumigation or solarization can be used to control nematodes before a new lawn is planted, however.

Are there any resistant vegetable varieties for nematodes?

Unfortunately, resistant vegetable varieties are only available for root-knot nematodes in a limited number of crops (table 2). Nematodes are unable to feed on a resistant variety, resulting in a population decline over time due to starvation (as long as weed hosts of the nematodes are also eliminated).

What plants are susceptible to root knot nematodes?

Other common garden vegetables grown during mid- to late summer, such as tomato, pepper, cucumber, squash, eggplant, and okra also are highly susceptible to root-knot nematode. Plants growing in nematode-infested soils usually are unthrifty, stunted, yellowish, and have galled and decayed roots.

How do I get rid of nematodes in my garden?

By alternating root-knot resistant and susceptible vegetables within a given portion of the garden from one year to the next, the overall nematode problem can be reduced by preventing a build-up of high populations. This practice will reduce the risk of serious damage to the susceptible vegetables.

What are some of the resistant crop varieties?
