To manage this disease, it is advisable to practice crop rotation, plant resistant cultivars, and prune infected leaves.
- Fusarium wilt: This is a soilborne fungal disease that causes stunted growth, yellowing of the leaves, and eventual wilting of the plant. There is no known cure for Fusarium wilt, it is advisable to prevent the disease by managing soil moisture and avoiding planting the crop in fields known to have been infected with the disease in the past.
Pest Management
In addition to diseases, pests may also affect the growth and yield of Crassocephalum ducis-aprutii (Chiov.) S.Moore. Here are some common pests that might attack the plant and ways to manage them:
