Slaters, also known as pillbugs or woodlice, are a common pest that can damage cucumber plants. These small, grey or brown insects feed on plant material and can cause yellowing or wilting of leaves. In this article, we will discuss different methods to get rid of slaters on cucumber plants.

Identify the Problem

Before you start treating your cucumber plant for slaters, it’s important to make sure they are the actual problem. Slaters are easy to identify as they are small, grey or brown insects that have a hard exoskeleton. They are generally found in damp areas and feed on decaying plant matter. Check the leaves and stems of your cucumber plant for evidence of slater damage.

Organic Methods

  1. Remove debris: Slaters prefer to hide in damp and dark areas, such as under debris and rocks. Remove any debris from your garden bed to reduce their hiding places.
  2. Reduce watering: Slaters thrive in damp conditions, so reducing watering can help to make your garden less hospitable for them.
  3. Apply diatomaceous earth: Diatomaceous earth is a fine powder made from fossilized diatoms. It works by dehydrating insects when they come into contact with it. Sprinkle diatomaceous earth around the base of your cucumber plant.

Chemical Methods

  1. Use insecticides: There are many insecticides available that can kill slaters. Look for ones that contain carbaryl or permethrin as they are effective against slaters.
  2. Apply bait traps: Bait traps can be an effective way to lure slaters away from your cucumber plants. Place the traps near the infested area and dispose of them once they are full.

Prevention

Preventing slater infestations is easier than getting rid of them. Here are some preventative measures that you can take:

  1. Plant in well-drained soil: Slaters thrive in damp soil, so planting your cucumber plants in well-draining soil can help to reduce the risk of infestation.
  2. Remove debris regularly: Regularly removing any debris from your garden bed can prevent slaters from finding a home in your garden.
  3. Use companion planting: Companion planting can help to deter pests such as slaters. Planting marigolds or garlic around your cucumber plants can help to keep slaters away.

Conclusion

Slaters can be a nuisance to cucumber plants but there are many methods available to get rid of them. Organic methods such as removing debris and applying diatomaceous earth are effective, while chemical methods such as insecticides and bait traps can also be used. Prevention is the best method, so be sure to plant your cucumber plants in well-draining soil and remove any debris regularly.
