How to Get Rid of Crusader Bugs on Marigold Plant

Marigolds are beautiful and vibrant flowers that are commonly grown in gardens and landscapes. They are not only aesthetically pleasing but also serve as a natural repellent for many insects due to their strong scent. However, one common pest that can cause significant damage to marigold plants is the crusader bug (Mictis profana).

Understanding Crusader Bugs

Crusader bugs, also known as Mictis profana, are small insects that belong to the family Coreidae. They are generally found in North America and are known for their distinctive green color and shield-like shape. These bugs primarily feed on the sap of plants, including marigolds, by piercing the plant tissue with their sharp mouthparts.

The damage caused by crusader bugs on marigold plants can be quite severe. They feed on the leaves, stems, and flowers of the plants, leaving behind yellow or brown patches and stunted growth. If left untreated, a heavy infestation of crusader bugs can even lead to the death of the plant.

Natural Methods to Control Crusader Bugs

If you notice crusader bugs infesting your marigold plants, it is essential to take immediate action to prevent further damage. Here are some effective natural methods to control crusader bugs on marigold plants:

1. Handpicking

One simple yet effective method to control crusader bugs is handpicking. Wear gloves and carefully inspect your marigold plants for any signs of crusader bug infestation. Look for the bugs themselves or any eggs they might have laid on the undersides of leaves or stems.

Once you spot them, gently remove them from the plant and drop them into a bucket filled with soapy water. This method might be time-consuming, especially if you have a large garden, but it can significantly reduce the population of crusader bugs and prevent further damage to your marigold plants.

2. Beneficial Insects

Introducing beneficial insects into your garden can provide a natural solution for controlling crusader bug infestations. Ladybugs, lacewings, and praying mantises are natural predators of crusader bugs and can help keep their population in check.

You can attract these beneficial insects to your garden by planting nectar-rich flowers such as daisies or cosmos nearby. Additionally, you can purchase ladybugs or praying mantis eggs from garden centers and release them onto your marigold plants to control the crusader bug population.

3. Neem Oil

Neem oil is a widely used natural pesticide that can be effective in controlling crusader bugs on marigold plants. It is derived from the neem tree and acts as both a repellent and an insecticide.

To use neem oil, dilute it according to the instructions on the packaging and spray it directly onto the affected marigold plants. Make sure to cover both the upper and undersides of the leaves as crusader bugs tend to hide there. Repeat this process every 7-10 days until the infestation is under control.

4. Homemade Garlic Spray

Garlic has natural insect-repellent properties, making it an excellent choice for controlling crusader bugs on marigold plants. To make a homemade garlic spray, crush a few cloves of garlic and steep them in hot water for several hours.

Once cooled, strain the mixture and pour it into a spray bottle. Spray the solution onto your marigold plants, focusing on the areas where you have noticed crusader bug activity. Reapply the garlic spray every few days until the infestation is eliminated.

5. Companion Planting

Companion planting involves strategically planting certain plants near marigolds to deter pests naturally. Some plants that can repel crusader bugs include catnip, mint, and tansy.

By interplanting these repellent plants with your marigold plants, you can create a natural barrier that makes it less attractive for crusader bugs to infest your garden. Additionally, the strong scent of these companion plants can confuse and deter the bugs from approaching your marigolds.

Prevention is Key

Preventing crusader bug infestations in the first place is crucial to maintaining healthy marigold plants. Here are some preventive measures you can take:

• Regularly inspect your plants: Regularly inspect your marigold plants for any signs of pest activity. Early detection can help prevent the spread of crusader bugs and minimize potential damage.

• Practice good garden hygiene: Removing any dead plant material or debris from your garden can help eliminate potential hiding places for crusader bugs.

• Avoid over-fertilization: Over-fertilizing your marigold plants can make them more attractive to pests, including crusader bugs. Follow the recommended fertilization guidelines to maintain a healthy balance in your garden.

• Use row covers: If you notice crusader bugs in nearby areas or have had previous infestations, consider using row covers to protect your marigold plants. These covers act as a physical barrier, preventing pests from reaching your plants.

Conclusion

Crusader bugs can be a significant nuisance for marigold plant owners, causing damage and stunting growth. However, by implementing natural control methods such as handpicking, introducing beneficial insects, using neem oil or homemade garlic spray, and practicing companion planting, you can effectively manage and eliminate crusader bug infestations. Remember to also focus on prevention by regularly inspecting your plants and maintaining good garden hygiene. With these measures in place, you can enjoy healthy and vibrant marigold plants throughout the growing season.
