Insects like cutworms, moth larvae and beet army worms are just some of the pests that attack your cabbage crops. Both young and old cabbage plants are susceptible to the discoloration, leaf wrinkling and holes that these bugs cause as they eat their way through the vegetation. These insects are harder to manage when they get larger, but if you take preventative measures right away, you can help ensure that your cabbage plants stay healthy.
Things You'll Need
Row cover
Insecticidal soap
Bacillus thuringiensis (Bt)
Place a row cover over your cabbage crops to protect them against insects like the cabbageworm and cabbage looper. The cabbageworm and cabbage looper are both caterpillars that bore large holes in the leaves of cabbage as they eat through it.
Remove any mustard family weeds found near your cabbage plants to prevent cabbage and turnip aphids. Once hatched, these aphids lay their eggs in mustard weeds and fly into your cabbages.
Spray your cabbages with water when you see pests like aphids and flea beetles. A direct stream of water dislodges pests on contact.
Apply an insecticidal soap to the cabbage to kill off pests like flea beetles and aphids. Read the instructions on the soap bottle to successfully control these early-season insects.
Apply a biological control such as Bacillus thuringiensis (Bt) if you see white butterflies in your cabbage garden. Spray this bacterium on your cabbages every seven to 10 days, and the butterfly larvae will die after ingesting the solution.
