What crops do wireworms eat?

What do wireworms do to crops?

They affect a wide variety of crops and can specifically render root crops unmarketable. They feed on oats, wheat, barley, clover, corn, carrots, lettuce, onions, peas, potatoes, parsnips, and cabbage. With five-year life cycles, the damage wireworms can do increases each year as they grow bigger.

What plants do wireworms attack?

Some species are soft, and white or yellowish in color. Wireworms are especially destructive to corn, but all the small grains and nearly all cultivated and wild grasses are attacked. Among the crops damaged are soybeans, potatoes, root crops, cabbage, and beans.

What do wireworms do to potatoes?

Adults do not damage potatoes, but the larvae, or wireworms, may damage seed pieces and young root systems during stand establishment, resulting in poor stands. More commonly the damage is seen as shallow to deep holes in the potatoes, caused by wireworms burrowing into the tuber while feeding.

How do you prevent wireworms in carrots?

Reduce levels of organic matter. Carrots are especially attractive to wireworms. Plant a nearly fully grown carrot in the soil every 2 1/2 to 3 feet throughout the garden. Every 2 to 3 days pull up the carrots, remove the wireworms, and replace the carrots in the soil to trap more wireworms.

How do I control wireworms in my garden?

Because wireworms have a wide host range, crop rotations are only moderately effective, however they can help reduce wireworm populations. Rotations with non-host crops such as onions, lettuce, alfalfa, sunflowers and buckwheat will reduce wireworm populations.
