What causes peanut leaves to suddenly turn white? Please advise.Peanuts are a warm-loving crop, heat-tolerant and drought-tolerant but not cold-tolerant. The optimum temperature for seedling growth is 26°C~30°C, and the minimum temperature is 14°C~16°C. This year the climate has been abnormal, with temperatures fluctuating up and down. Some time ago, various places experienced sharp drops in temperature, which caused peanut leaves to suffer cold damage, showing varying degrees of chlorosis, whitening, and even scorching symptoms. After the weather cleared, the symptoms became especially obvious. There is no need to panic when this happens, and there is no need to spray insecticides or fungicides. After the weather clears and temperatures rise, the peanut leaves will automatically turn green again and resume growth. If you use Tianda 2116, a cell membrane stabilizer with the ability to repair crop freeze damage, or spray a mixed solution of rice vinegar, white sugar, monopotassium phosphate, and urea on the frozen peanuts, growth will recover faster.
