Why Peanut Leaves Turn White

May 14, 2021

Peanuts are hi-temperature crops that are heat- and drought-tolerant but not cold-resistant. The optimum temperature for seedling growth is 26°C~30°C, and the minimum temperature is 14°C~16°C. This year's climate is abnormal and the temperature is high and low. Some time ago, significant temperature reductions occurred in various parts of the country, resulting in frozen leaves of peanuts and symptoms of chlorosis, whitening and even scorching. After sunny days, the symptoms are particularly evident. This situation does not have to panic, do not have to spray pesticides or fungicides, after sunny temperatures rise, peanut leaves will automatically turn green to restore growth. If Tianda 2116, a cell membrane stabilizer with the ability to repair crops with freezing damage, is used, or if rice vinegar, white sugar, potassium dihydrogen phosphate, and urea are mixed together to apply foliar spray to frozen peanuts, the recovery will be faster.
