Management of Grey mildew of cotton through agro-chemicals.

摘要

The experiments were carried out at the Regional Agricultural Research Station, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Khandwa, for two years 1998-1999 and 1999-2000, under rainfed conditions. The pooled data for two seasons indicate that propiconozole treatment (14.39%) was most effective and significantly superior over all treatments in reducing the per cent disease incidence of Grey mildew. The highest per cent disease control was recorded for propiconozole (77.19%). While the highest seed cotton yield was recorded for carbendazim treatment (532.41 kg/ha), which was significantly superior over all other treatments. The highest per cent increase in seed cotton yield over control was recorded for carbendazim (27.07%), while the increase ranged from 5.53 to 23.77 per cent for rest of the treatments as compared to control.
