@ Rajashekhar, it is a physiological disorder in Cotton crop. For management you may do the following: Provide adequate drainage to avoid water logging of the fields, Irrigation may be provided during grand growth phase to avoid prolonged exposure of plants to dry conditions , Apply 2% urea through foliar spray , Apply copper oxychloride 25g per 10 litres water by drenching near the root zone of infested and healthy plants , Apply cobalt chloride 1g/ 100 litres water immediately after the appearance of symptoms.
Thank you sir. Sir, Cobalt chloride is available in market. If available in which form it is available sir.
It's a physiological disorder rather you perceive it as a disease, because no biological agents are involved in this and it is mainly associated with the root respiration
