How to Get Rid of Crusader Bugs on Green Onion Plant

Green onions, also known as scallions, are a popular vegetable in many cuisines. They are easy to grow and can be harvested in just a few weeks. However, green onions are susceptible to pests like crusader bugs, which can cause significant damage to the plant if left unchecked.

If you have noticed crusader bugs on your green onion plants, don’t worry. In this article, we will discuss the most effective methods for getting rid of these pesky insects and keeping your green onion plants healthy.

Identifying Crusader Bugs

Before we dive into the ways to get rid of crusader bugs on green onion plants, it’s essential to know how to identify them. Crusader bugs are small, oval-shaped insects that are usually black or dark brown. They have long antennae and feed on the sap of plants, causing leaves to wilt and turn yellow.

If you notice small holes in your green onion leaves or see insects on the underside of the leaves, it’s likely that you have a crusader bug infestation.

Organic Methods for Getting Rid of Crusader Bugs

1. Handpicking

The most straightforward method for getting rid of crusader bugs is handpicking them off the plant. Wear gloves and carefully pluck the bugs off the leaves and stems of your green onion plant. Be sure to dispose of them in a sealed container or kill them by squishing them with your fingers.

1. Neem Oil

Neem oil is an organic insecticide that is effective against a wide range of pests, including crusader bugs. Mix 2 tablespoons of neem oil with 1 gallon of water and spray it onto your green onion plant, paying close attention to the undersides of the leaves where the bugs tend to hide.

Repeat this process every 7-10 days until all signs of the infestation have disappeared.

1. Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of diatoms. It is an effective insecticide that works by dehydrating the insects’ exoskeletons, causing them to die.

Sprinkle diatomaceous earth around the base of your green onion plant and on the leaves where you have noticed crusader bugs. You can also mix it with water to create a spray and apply it to the plant.

1. Soap Spray
