Takeaways

• 😀 Red onion plants are highly vulnerable to several pests that negatively affect their growth and productivity.
• 😀 There are six main pests that affect red onion plants, leading to reduced yield and quality.
• 😀 The first major pest is soil caterpillars, which attack at night by cutting the stems of red onion plants.
• 😀 Soil caterpillars damage the plants by cutting and hiding the plant parts, leading to wilting and stunted growth.
• 😀 The second pest is the cutworm, which primarily attacks young plants or those fertilized recently, damaging leaves from the inside.
• 😀 The third pest is trips, which damages the new leaves by causing white, shiny spots that turn brown with black dots, leading to poor bulb growth.
• 😀 The fourth pest is aphids, which cause leaf curling, yellowing, stunted growth, and eventually wilting and plant death.
• 😀 The fifth pest is Fusarium fungus, which causes wilting and discoloration of the plant's base and root decay, making it highly contagious.
• 😀 The sixth pest is grubs, which cut the young plant's base, leading to the plant falling over and dying.
