If you are a gardener who grows coriander, you may have experienced the frustration of dealing with crusader bugs. These tiny pests can wreak havoc on your coriander plant by sucking out the sap and causing the leaves to wilt and turn yellow. Luckily, there are several methods you can use to get rid of crusader bugs without harming your plant.
Identifying Crusader Bugs
Before you can effectively treat your coriander plant for crusader bugs, it’s important to be able to identify them. These bugs are small and oval-shaped, with green or yellow stripes on their wings. They are most commonly found on the undersides of leaves and can be difficult to see with the naked eye.
Natural Remedies for Crusader Bugs
One of the best ways to get rid of crusader bugs on your coriander plant is to use natural remedies. These remedies are safe for both your plant and the environment and won’t harm beneficial insects like bees or ladybugs.
Neem oil is a natural insecticide that works by disrupting the feeding and mating behavior of insects. To use neem oil on your coriander plant, mix one tablespoon of neem oil with one gallon of water and spray the mixture onto the plant, making sure to cover both sides of the leaves. Repeat this process every week until the crusader bugs are gone.
A soap spray made from natural ingredients can also be effective in getting rid of crusader bugs. Mix one tablespoon of liquid soap with one gallon of water and spray the mixture onto the plant, making sure to cover both sides of the leaves. Repeat this process every few days until the bugs are gone.
Garlic is a natural insect repellent that can help keep crusader bugs away from your coriander plant. To make a garlic spray, crush several cloves of garlic and mix them with one quart of water. Let the mixture sit for a few hours, then strain out the garlic and spray the remaining liquid onto your plant.
Chemical Remedies for Crusader Bugs
If natural remedies don’t work, you may need to resort to chemical remedies to get rid of crusader bugs. These remedies are more potent than natural remedies and should be used with caution.
Insecticidal soap is a chemical pesticide that works by suffocating insects. To use insecticidal soap on your coriander plant, mix the soap according to the instructions on the label and spray it onto the plant, making sure to cover both sides of the leaves. Repeat this process every few days until the bugs are gone.
Pyrethrin is a chemical pesticide that is derived from chrysanthemum flowers. It works by disrupting the nervous system of insects. To use pyrethrin on your coriander plant, mix it according to the instructions on the label and spray it onto the plant, making sure to cover both sides of the leaves. Repeat this process every few days until the bugs are gone.
