Abstract

Coriander (Coriandrum sativum L.) is a significant spice crop known locally as "Dhana" or "Kothmir" that belongs to the Umbelliferae family and is primarily grown in India. It caused significant damage in South Gujarat. Given the high disease incidence and economic damage caused by powdery mildew disease, an experiment was conducted to evaluate the performance of several fungicides in the field for powdery mildew disease management. Reduce the yield loss of coriander due to powdery mildew disease through proper fungicides at right time is aim to study. All of the fungicides tested considerably reduced disease compared to the control. Propiconazole 25 EC (0.025%) was found to be the most effective against with a minimum of 19.17 percent disease intensity and a maximum of 72.80 percent disease control, followed by hexaconazole 5 EC (0.025%) with a minimum of 23.17 percent disease intensity and a decrease of 67.13 percent disease intensity over the control after two sprays at 15-day intervals. Similarly, the maximum seed yield was 1106.17 kg ha-1 with an increase of 160.47% over control with the application of propiconazole (0.025%), which was equal to hexaconazol (0.025%) by 958.02 kg ha-1 with an increase of 125.58% yield over the control treatment. The minimum seed output in the control treatment was 424.69 kg ha-1. The study found that two sprays of propiconazole (0.025%) and hexaconazole 5 EC (0.025%) at 15-day intervals are the most efficient fungicides for managing coriander powdery mildew.

Conclusion

Two sprayed at 15 days interval of propiconazole (0.025%) and hexaconazole (0.025%) were found highly effective to reduced 72.80 and 67.13 per cent disease intensity, respectively. Similarly, highest seed yield 1106.17 kg ha-1 by increased 160.47 per cent over the control was recorded in propiconazole (0.025) which was at par with hexaconazol by 958.02 kg ha-1 with increased 125.58 per cent. While seed yield in wettable sulphur (0.2%), 770.37 kg ha-1 seed yield was recorded with 81.40 per cent increased over control.
