How to ripen cotton correctly with ethephon
Many years 'practice shows that it is a simple and easy measure to use ethephon correctly to accelerate ripening of late-maturing cotton field, which can increase yield and income. Late maturing cotton sprayed with ethephon could open boll 7-10 days earlier, flower rate before frost increased by 10%-20%, yield increased by 6.4%-10.2%, and yield increased per mu.
