2. Bacterial wilt: Bacterial wilt is a severe disease that can lead to the death of the plant. Symptoms include wilting, yellowing of leaves, and stunted growth. To manage bacterial wilt, it is best to remove and destroy infected plants immediately. Use disease-free planting material and avoid planting in areas that have a history of bacterial wilt.
Common Pests
1. Aphids: Aphids are small, soft-bodied insects that can suck the sap from the plant and cause wilting and yellowing of leaves. To manage aphids, you can use insecticidal soap or neem oil. You can also introduce natural predators such as ladybugs and lacewings to control their population.
2. Mealybugs: Mealybugs are white, cotton-like insects that also suck the sap from the plant. They can cause stunted growth and yellowing of leaves. To manage mealybugs, use a soft brush or cotton swab dipped in alcohol to remove them from the plant. Use insecticidal soap or neem oil to eliminate severe infestations.
3. Spider mites: Spider mites are tiny, spider-like insects that suck the sap from the plant, causing small yellow spots on the leaves. They prefer dry conditions and thrive in hot weather. To manage spider mites, use a forceful stream of water to wash away the mites from the foliage. You can also use insecticidal soap or neem oil to control severe infestations.
