Main Cabbage Pests, Diseases Pictures and Control

This post is about Cabbage pests diseases pictures and control.

You want to know how to get rid of cabbage pests and diseases in your garden or on your balcony?

Stick with me since I will show you different cabbage pests, diseases pictures and tips and tricks on how you can control cabbage plant diseases and pests in the following chapters.

Cabbage pests including cabbage worms, cutworms, root maggots, etc. can cause severe damage to your cabbage farm leading to huge losses.

Now lets get deep into Cabbage Pests and Diseases Pictures.

What is a pest?

A pest is any organism that spreads disease, causes destruction or is otherwise a nuisance. Some examples of pests are mosquitoes, rodents, and weeds.

Not all insects are pests. Many different kinds of insects eat other insects and are beneficial species.

Categories of pests.

Pests can be broken into four main categories

  • Vertebrate Pests. Have a backbone. Examples: Rodents, birds, reptiles, and other mammals.
  • Invertebrate Pests. No backbone. Examples: Insets, spiders, ticks, slugs.
  • Weeds. Any plant growing out of place.
  • Diseases. Fungi, bacteria, viruses, and other microorganisms.

Now that you know what pest is let take a look on common cabbage pests, diseases they cause and how to control them.

1. Cabbage worms

The term cabbage worm is primarily used for any of four kinds of lepidopteran whose larvae feed on cabbages and other cole crops.

Favorite foods include broccoli, cauliflower, Brussels sprouts, collards, kale, mustard greens, turnip greens, radishes, turnips, rutabagas and kohlrabi.

This small group of similar pest species is known to agriculturists as the cabbage worm compte butterflies

What does it looks like?

Cabbage worms are velvety green larvae. They have a few faint yellow stripes. 

Damage caused by Cabbage worm

Cabbage worm damage are holes in the leaves or flower stalks (as is often the case with broccoli), skeletonized leaves, and the presence of their dark green, round, pelleted excrement, called frass.

What happens if you eat a cabbage worm?

It has no known toxic effect on humans, birds, pets, bees or other beneficial insects.

How to prevent cabbage worm

Spraying with Bt (Bacillus thuringiensis var. kurstaki) every 1 to 2 weeks will also help control cabbage family pests.

Sevin also is effective. And, the few pests that remain on the vegetables can be washed out after harvest using water and a small amount of detergent or other surfactant.

2. Cutworms

Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants.

A larva typically attacks the stem part of the plant it encounters, and consequently cuts it down; hence the name cutworm.

Cutworms are not worms, biologically speaking, but caterpillars.

What does cutworm look like?

Cutworms are similar in general appearance. They are smooth with very few hairs and are about two inches when fully grown.

They typically curl into a tight ‘C’ shape when disturbed.

Different species can look different from one another and they can range in color from brown or pink, green or gray and black.

Damage caused by cutworms

Cutworms are general feeders that can attack a wide range of plants.

Cutworms curl their bodies around the stem and feed on it. This feeding causes the plant to be cut off just above the soil surface.

How to control cutworm

A wash of bleach-free dish soap and water on your plants can also help to stop cutworms from attacking the plants.

Another approach is the use of Bacillus thuringiensis (Bt), a naturally occurring bacterium that target many caterpillar-type pests.

3. Root Maggots

Root maggots are the larvae of different species of flies.

Some species are commonly called “root-maggots”, as the larvae are found in the stems and roots of various plants.

As larvae, some also feed on decaying plant material. The well-known grey “seaweed flies” or “kelp flies” (Fucellia) are examples.

What does root maggots looks like?

Root maggots are white and about ¼ of an inch (6 mm.) long.

Often an infestation will not be spotted until after damage is done.

Damage shows up in the form of holes or tunnels in the roots or tubers of the plant.

How to prevent root maggots

Once root maggots are feeding on a plant, there is no chemical to kill them. Root maggot control is all about prevention.

Common organic cures for root maggot include spreading diatomaceous earth around the plants while they are seedlings, floating row covers over seedlings, and using natural predators of root maggots such as Heterorhabditidae or Steinernematidae nematodes and rove beetles to kill the root maggots.

4. Flea Beetle

The flea beetle is a small, jumping beetle of the leaf beetle family, that makes up the tribe Alticini which is part of the subfamily Galerucinae.

Flea beetles are common pests found on many vegetable crops including radishes, broccoli, cabbage, turnips, eggplant, peppers, tomatoes, potatoes, spinach and melons.

What does flea beetle looks like?

Flea beetles look like tiny beetles. They’re shiny, and can appear to be black, brown or even bluish in color. Some species may even have spots or stripes.

It’s hard to see flea beetles from a distance, so infestations can easily go unnoticed.

A quick way to make a positive identification is to disturb the plant or surrounding soil. Flea beetles start jumping around when they are disturbed.

Damage caused by flea beetles

Adult flea beetles cause the most damage by feeding on the leaves and stems.

They create shallow pits and small rounded, irregular holes (usually less than 1/8 inch) in the leaves. This type of damage is unique to flea beetles.

Flea beetles usually don’t cause fatal damage to established plants because the leaves are already large enough to survive a few holes.

How to control Flea Beetles

Try this homemade spray to control flea beetles: 2 cups isopropyl alcohol, 5 cups water, and 1 tablespoon liquid soap.

Test out the mixture on a leaf of the plant, let it sit overnight, then spray the rest of the plant if you don’t notice any adverse effects.

Spray the mixture on the foliage of garden plants that are susceptible to these pests.

Also dusting leaves with plain talcum powder repels flea beetles on tomatoes, potatoes, peppers, and other plants.

5. Aphids

Aphids are small sap-sucking insects and members of the superfamily Aphidoidea.

Common names include greenfly and blackfly, although individuals within a species can vary widely in color.

The group includes the fluffy white woolly aphids

What do aphids looks like?

Aphids are tiny (adults are under 1/4-inch), and often nearly invisible to the naked eye.

Various species can appear white, black, brown, gray, yellow, light green, or even pink! Some may have a waxy or woolly coating.

Aphids become more of a problem when things get out of whack, usually when plants are stressed by drought, poor soil conditions, or overcrowding.

Damage caused by Aphids

Aphids cause damage and lower agricultural yields in several ways.

They can build to high population densities, removing plant nutrients, and may damage plants by removing enough sap to cause withering and death.

Look for misshapen, curling, stunted, or yellowing leaves. Be sure to check the undersides of leaves; aphids love to hide there.

How to control Aphids

If insecticides are needed, insecticidal soaps and oils are the best choices for most situations. Oils may include petroleum-based horticultural oils or plant-derived oils such as neem or canola oil.

These products kill primarily by smothering the aphid, so thorough coverage of infested foliage is required.

Conclusion

Cabbage production can be minimized not only by the above mentioned disease but also when they lack essential nutrients and care

Cabbage needs nutrient-rich soil in order to grow and maximize production and yields.

Some cabbage farmers apply a well-rotted manure and plow the soil two weeks before planting.

They also report that they can add fertilizer to the young seedlings about two weeks or three weeks after transplant.
