Diseases
Leaf spot: This fungal disease causes small brown or black spots on the leaves. It can be managed by removing and destroying the affected leaves and avoiding overhead watering, which spreads the spores. Fungicides may also be applied.
Root rot: This disease is caused by soggy soil conditions and affects the roots, causing them to turn brown and mushy. To manage it, ensure good drainage and avoid overwatering. Planting in raised beds or containers can also help.
Viral diseases: Viral diseases affect the plant's growth and can cause discoloration and stunted growth. There is no cure for viral diseases, so prevention is key. This can be achieved by using disease-free seedlings, practicing good sanitation, and controlling insect vectors.
Pests
Spider mites: These tiny pests are known for causing yellowed leaves and fine webbing. Regularly spraying the plant with water can help prevent spider mites. In severe cases, insecticidal soap or neem oil may be applied.
Aphids: These small, pear-shaped insects can cause curled leaves and a sticky residue on the plant. They can be managed by spraying the plant with a strong jet of water and using insecticidal soap or neem oil when necessary.
Caterpillars: These pests can eat the leaves and stems of the plant, causing significant damage. They can be removed by handpicking, and Bacillus thuringiensis (BT) is an effective biological control.
