These sap-sucking pests weaken plants by extracting essential nutrients from the leaves, causing them to curl, distort, and turn yellow. Onion aphids also secrete a sticky substance known as honeydew, which attracts ants and promotes the growth of sooty mold, further reducing plant health and yield. Symptoms of Onion Aphid Infestation Causes of Onion Aphid Infestation Impact on Onion Crops Prevention Measures for Onion Aphids 1. Crop Rotation: Avoid planting onions or related crops in the same field consecutively to disrupt the aphid life cycle. 2. Sanitation Practices: Regularly remove and destroy plant debris and volunteer Allium species that can serve as breeding grounds for aphids. 3. Companion Planting: Grow aromatic herbs like rosemary, mint, or basil near onions to naturally repel aphids. 4. Balanced Fertilization: Avoid excessive nitrogen, as it encourages excessive vegetative growth, making onions more attractive to aphids. 5. Encourage Natural Predators: Beneficial insects such as ladybugs, lacewings, and parasitic wasps help keep aphid populations in check.
