Tomatillos are popular plants that are widely used in Mexican cuisine. However, like any plant, they can be susceptible to pests. One common pest that can wreak havoc on tomatillo plants is the crusader bug. These insects feed on the sap of the plant, causing damage and potentially even killing it if left untreated. In this article, we will discuss how to identify crusader bugs and provide effective methods for getting rid of them.

Identifying Crusader Bugs

Crusader bugs, also known as leaf-footed bugs, are medium-sized insects with a distinct appearance. They are usually about 1 inch long and have a dark brown or black coloration. One of their most noticeable features is their hind legs, which are flattened and shaped like leaves. This unique characteristic gives them their name.

When it comes to tomatillos, crusader bugs can cause significant damage. They feed on the plant’s sap by piercing the stems and leaves with their mouthparts. This feeding behavior can result in wilted leaves, stunted growth, and even fruit drop. Additionally, crusader bugs can transmit diseases to the plant, further compromising its health.

Prevention is Key

As with any pest problem, prevention is key when it comes to crusader bugs on tomatillo plants. Here are some proactive measures you can take to minimize the risk of an infestation:

  1. Maintain proper garden hygiene: Clear away any debris or fallen plant material around your tomatillo plants regularly. This will eliminate potential hiding places for crusader bugs and other pests.

  2. Rotate crops: Avoid planting tomatillos in the same location year after year. Crop rotation helps disrupt the life cycle of pests and reduces the likelihood of an infestation.

  3. Use companion planting: Certain plants, such as marigolds and catnip, are known to repel crusader bugs. Consider interplanting these companion plants with your tomatillos to deter the pests naturally.

Natural Remedies

If you notice crusader bugs on your tomatillo plants despite your preventive efforts, there are several natural remedies you can try to get rid of them:

  1. Handpicking: If you only have a few crusader bugs on your plants, you can manually remove them by hand. Wear gloves and carefully pick the insects off the plant. Drop them into a bucket of soapy water to ensure they do not return.

  2. Insecticidal soap: Insecticidal soap is an effective and environmentally friendly solution for controlling crusader bugs. Mix a tablespoon of mild liquid soap with a gallon of water and spray it directly onto the insects. The soap will suffocate the bugs, killing them without harming your plants.

  3. Neem oil: Neem oil is derived from the neem tree and has insecticidal properties. Mix one ounce of neem oil with a gallon of water and spray it onto your tomatillo plants, paying special attention to the leaves and stems where the crusader bugs are present. Repeat this treatment every seven to ten days until the infestation is under control.

Organic Pesticides

If natural remedies do not provide satisfactory results, you may consider using organic pesticides as a last resort:

  1. Pyrethrin-based insecticides: Pyrethrin is a natural pesticide derived from chrysanthemum flowers. It is effective against crusader bugs and many other garden pests. Follow the instructions on the product label and apply the insecticide according to the recommended dosage.

  2. Spinosad: Spinosad is an organic insecticide made from soil bacteria. It is safe to use around pets and beneficial insects, making it an excellent choice for organic gardening. Mix the recommended amount of spinosad with water and spray it onto your tomatillo plants, targeting the areas where the crusader bugs are present.

Conclusion

Dealing with crusader bugs on your tomatillo plants can be challenging, but with proper identification and timely action, you can effectively control and eliminate the infestation. Remember to implement preventive measures, such as maintaining garden hygiene and practicing crop rotation, to minimize the risk of an infestation in the first place. If natural remedies do not yield satisfactory results, organic pesticides can be used as a last resort. By following these steps, you can protect your tomatillo plants and ensure a bountiful harvest of delicious fruits.
