Watermelon is a delicious and refreshing fruit that is enjoyed by many. However, growing watermelon plants can be challenging, especially when it comes to dealing with pests. One of the most common pests that affect watermelon plants is the Crusader bug. These bugs are small but can cause significant damage to your plants if left untreated. In this article, we will discuss how to get rid of Crusader bugs on watermelon plants.
Before we discuss how to get rid of Crusader bugs, it is essential to know how to identify them. Crusader bugs are small, green or brown insects that are approximately 0.5 inches long. They have a distinctive triangular shape and are often mistaken for stink bugs. However, Crusader bugs have a pointed head and a more elongated body than stink bugs.
Crusader bugs feed on the sap of the watermelon plant by piercing the plant’s tissue with their mouthparts. This feeding causes damage to the plant, leading to wilting, stunted growth, and reduced yields. Additionally, Crusader bugs excrete a sticky substance known as honeydew, which attracts other pests like ants and bees.
There are several natural methods for getting rid of Crusader bugs that you can try before resorting to chemical insecticides. Here are some of them:
One effective way of controlling Crusader bugs is by handpicking them off the plants. This method works best when there are only a few bugs present on the plant. Look for the bugs on the underside of leaves or around the flowers and remove them by hand.
Neem oil is a natural insecticide that is effective against a wide range of pests, including Crusader bugs. It works by disrupting the bug’s hormonal balance, making it difficult for them to feed and breed. Mix one tablespoon of neem oil with a gallon of water and spray the solution on the watermelon plants. Repeat this process every two weeks until the bugs are gone.
Insecticidal soap is another natural method for getting rid of Crusader bugs. It works by suffocating the bugs, causing them to die. Mix two tablespoons of insecticidal soap with a gallon of water and spray the solution on the watermelon plants. This method is safe for humans and animals but can harm beneficial insects like bees.
If natural methods do not work, you may need to resort to chemical insecticides to get rid of Crusader bugs. However, it is essential to use these insecticides with caution as they can harm beneficial insects and contaminate the environment. Here are some of the chemical insecticides that are effective against Crusader bugs:
Acephate is a systemic insecticide that works by interfering with the nervous system of insects. It is effective against a wide range of pests, including Crusader bugs. Mix one tablespoon of acephate with a gallon of water and spray the solution on the watermelon plants.
Carbaryl is a broad-spectrum insecticide that is effective against a wide range of pests, including Crusader bugs. It works by disrupting the bug’s nervous system, leading to paralysis and death. Mix one tablespoon of carbaryl with a gallon of water and spray the solution on the watermelon plants.
A: To prevent Crusader bugs from infesting your watermelon plants, you can use row covers to keep them away from your plants. Additionally, keeping your garden free of debris and weeds can help reduce the likelihood of infestation.
A: No, Crusader bugs are not harmful to humans. However, they can cause significant damage to watermelon plants.
A: It is generally safe to eat watermelons that have been treated with insecticides. However, it is essential to follow the instructions on the insecticide label carefully and wait for the recommended time before harvesting the watermelons.
Getting rid of Crusader bugs on watermelon plants can be challenging, but it is not impossible. By using natural methods or chemical insecticides, you can effectively control these pests and protect your watermelon plants from damage. Remember to use insecticides with caution and follow the instructions on the label carefully. With proper care and attention, you can enjoy a bountiful harvest of delicious and healthy watermelons.
