Introduction

Slaters, also known as woodlice or pill bugs, are common pests that can wreak havoc on hop plants. These small crustaceans feed on decaying organic matter and are attracted to the moist environment around hop plants. While they may seem harmless, slaters can cause significant damage to the leaves and stems of hop plants if left unchecked. In this article, we will discuss various methods to effectively get rid of slaters and protect your hop plants.

Prevention is Key

As with most pests, prevention is the best approach to deal with slaters on hop plants. By implementing a few simple practices, you can create an environment that is less attractive to these pests.

  1. Clear the Area: Slaters thrive in areas with decaying organic matter such as dead leaves and grass clippings. Regularly clean up any debris around your hop plants to reduce their hiding spots.

  2. Improve Drainage: Slaters prefer moist environments, so it’s important to ensure proper drainage around your hop plants. Avoid overwatering and make sure the soil has good drainage to discourage slaters from settling in.

  3. Mulching: Use a layer of mulch around the base of your hop plants. This not only helps with moisture retention but also creates a barrier that makes it difficult for slaters to reach the plant.

Natural Remedies

If you already have slaters infesting your hop plants, there are several natural remedies you can try before resorting to chemical pesticides.

  1. Diatomaceous Earth: Sprinkle food-grade diatomaceous earth around the base of your hop plants. This powdery substance is made from fossilized remains of algae and has sharp edges that cut through the exoskeleton of slaters, ultimately causing their demise.

  2. Beer Traps: Create beer traps by burying containers, such as yogurt cups or shallow dishes, in the ground near your hop plants. Fill them with beer, which will attract slaters. The slaters will crawl in and drown in the beer. Empty and refill these traps regularly.

  3. Citrus Peels: Slaters are repelled by the scent of citrus. Place citrus peels around your hop plants to deter these pests.

  4. Predatory Insects: Introduce natural predators of slaters, such as ground beetles or centipedes, into your garden. These insects feed on slaters and can help keep their population in check.

Chemical Control

If natural remedies fail to eliminate the slater infestation, you may need to resort to chemical control methods. However, it’s important to use chemical pesticides as a last resort and follow the instructions carefully to avoid harming beneficial insects and pollinators.

  1. Insecticides: Look for insecticides specifically designed for slaters or sowbugs. Follow the instructions on the label and apply the pesticide to the affected areas of your hop plants.

  2. Contact and Barrier Sprays: Contact sprays are designed to kill pests on contact while barrier sprays create a protective barrier around your hop plants. Use these sprays sparingly and only when necessary.

  3. Systemic Insecticides: Systemic insecticides are absorbed by the plant and kill pests when they feed on the plant tissues. These are often used as a last resort due to their potential impact on beneficial insects.

Regular Monitoring and Maintenance

Once you have successfully eliminated the slaters from your hop plants, it’s important to maintain regular monitoring and maintenance practices to prevent another infestation.

  1. Inspect Regularly: Check your hop plants regularly for any signs of slater activity. Look for damaged leaves, chewed stems, or clusters of slaters.

  2. Remove Debris: Continuously clean up any dead leaves or decaying organic matter around your hop plants to eliminate potential hiding spots for slaters.

  3. Prune and Trim: Prune any damaged or infected parts of your hop plants promptly to prevent the spread of pests and diseases.

  4. Maintain Proper Moisture Levels: Avoid overwatering your hop plants, as excessive moisture can attract slaters. Ensure the soil has good drainage and water only when necessary.

Conclusion

Slaters can be a nuisance for hop plant growers, but with proper prevention, natural remedies, and, if necessary, chemical control methods, you can effectively get rid of them and protect your hop plants. Remember to prioritize prevention by maintaining a clean and dry environment around your plants. Implement natural remedies as the first line of defense and only resort to chemical control when all else fails. Regular monitoring and maintenance will ensure that your hop plants stay healthy and free from slater infestations.
