How to manage a cotton field after a sudden shift from drought to waterlogging?
Right now, cotton is at the stage when vegetative growth is entering its peak and gradually shifting to reproductive growth, and it is also a period when the crop absorbs more fertilizer and water and is very sensitive. Since June 4, there have been many overcast and rainy days, the air humidity is very high, and the temperature has hovered between 25 and 30°C. Fusarium wilt has been triggered in many old cotton fields that have been planted for years. The rate of wilted plants is generally around 5%, in severe fields the rate of diseased plants is around 10%, and in some sections the incidence rate is around 20%. In some cotton fields, tarnished plant bugs, cotton bollworms, red spiders, and aphids are also causing damage in spots and patches.
