How to Get Rid of Slaters on Rhubarb Plant

Rhubarb is a popular garden plant known for its vibrant red stalks and tart flavor. However, like any other plant, it can be susceptible to pests. One such pest that can cause damage to rhubarb plants is slaters, also known as woodlice or pillbugs. These small crustaceans are usually harmless, but when their population increases and they start feeding on the rhubarb leaves, they can become a nuisance. In this article, we will discuss different methods to get rid of slaters on your rhubarb plant.

Understanding Slaters

Before we delve into the methods of getting rid of slaters, it is important to understand their behavior and characteristics. Slaters are small, grayish-brown crustaceans that measure about 1 cm in length. They have a segmented body and seven pairs of legs. Slaters are mostly active at night and prefer damp and dark environments.

Slaters feed on decaying organic matter such as dead plants and wood. They are known to consume rotting rhubarb leaves, which can lead to unsightly damage to the plant. While they rarely cause severe harm to the plant itself, their presence can be an indication of other underlying issues in the garden, such as excessive moisture or poor soil drainage.

Natural Methods to Control Slaters

If you notice slaters infesting your rhubarb plant, there are several natural methods you can try before resorting to chemical pesticides. These methods are safe for both the environment and your rhubarb plants.

1. Reduce Moisture Levels

As mentioned earlier, slaters thrive in damp environments. By reducing moisture levels around the rhubarb plant, you can discourage their presence. Avoid overwatering your rhubarb and ensure proper drainage in the soil. Additionally, avoid watering in the evening to prevent excess moisture from lingering overnight.

2. Provide Proper Air Circulation

Slaters prefer dark and humid areas, so providing proper air circulation can help deter them. Trim surrounding vegetation to allow air to flow freely around the rhubarb plant. This will not only discourage slaters but also prevent other pests and diseases from taking hold.

3. Remove Hiding Places

Slaters love hiding in dark, damp crevices during the day. Remove any debris, rocks, or logs near the rhubarb plant that could serve as potential hiding spots. By eliminating their hiding places, you make it more difficult for slaters to infest your plant.

4. Introduce Natural Predators

Certain animals feed on slaters and can help control their population. For instance, birds such as robins and blackbirds are known to prey on slaters. Encouraging these birds to visit your garden by providing bird feeders or bird baths can help keep the slater population in check.

Organic Pest Control Methods

If natural methods fail to control the slater population on your rhubarb plant, there are organic pest control methods you can try.

1. Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of algae-like plants called diatoms. It is highly effective against various pests, including slaters. Sprinkle a thin layer of diatomaceous earth around the base of the rhubarb plant and on the leaves. When slaters come into contact with the powder, it dehydrates them, leading to their demise.

2. Beer Traps

Beer traps are a popular method for controlling slaters and other garden pests. Fill a small container, such as a shallow dish or jar lid, with beer and bury it in the soil near the rhubarb plant. Slaters are attracted to the yeasty smell of the beer and will crawl into the trap, where they will drown. Empty and refill the traps regularly for maximum effectiveness.

3. Copper Barriers

Slaters are deterred by copper, so placing copper barriers around your rhubarb plant can prevent them from reaching the leaves. Copper tape or wire can be wrapped around the base of the plant or placed in a circle around it. As slaters come into contact with the copper, it releases a mild electric shock that repels them.

Conclusion

Slaters can be a nuisance when they infest your rhubarb plants, but with the right methods, you can effectively control their population. By reducing moisture levels, providing proper air circulation, removing hiding places, and introducing natural predators, you can deter slaters from your garden. If these natural methods fail, organic pest control methods such as diatomaceous earth, beer traps, and copper barriers can be effective alternatives. Remember to always opt for environmentally-friendly solutions before resorting to chemical pesticides. With these strategies in place, you can enjoy healthy and vibrant rhubarb plants without the annoyance of slaters.
