‘Pichi poo’ is a sought-after flower for garlands used in temples and ceremonies, contributing to its economic importance for farmers.
Root rot spreads through soil, especially when soggy and fungal spores multiply.
Control measures include planting in well-drained soils, using resistant varieties, and removing affected plants. Fungicides can also treat the soil.
The Tiruchy area cultivates red jasmine across approximately 1,000 acres, supplying the flower to various parts of the state.
