What is the reason why peanut leaves suddenly turn white? Please guide that peanuts are temperature-loving crops, heat-resistant, drought-tolerant but not cold-tolerant. The optimum temperature for seedling growth was 26 ℃ ~ 30 ℃, and the lowest temperature was 14 ℃ ~ 16 ℃. The weather is abnormal this year, with temperatures fluctuating from high to low. Some time ago, there has been a substantial drop in temperature in various places, resulting in peanut leaves frozen, showing varying degrees of chlorosis, whitening and even scorching symptoms. When the weather clears up, the symptoms are especially obvious. There is no need to panic when this happens, and there is no need to spray pesticides or fungicides. After the sunny temperature picks up, the peanut leaves will automatically turn green and resume growth. If Tian Da 2116, a cell membrane stabilizer capable of repairing crop freezing injury, is used, or the mixture of rice vinegar, sugar, potassium dihydrogen phosphate and urea is used to spray on frozen peanuts, the growth rate can be restored more quickly.
