How to distinguish the stem blight and brown wilt of cotton leaves
Red leaf blight is red and purple from the bottom of the old leaves, leaves stiff, if the disease is severe, the top leaves may appear leaf spots, and eventually fall off. The disease is mainly caused by potassium deficiency, also known as potassium deficiency red stem blight. Fusarium wilt occurs from late 6 to mid-July. In the rainy days, when the temperature drops, it is easy to cause disease, resulting in irregular yellow spots on the leaves, or dry leaves, causing leaf shrinkage. To prevent red stem blight, potassium fertilizer should be sprayed on the leaves in time, once every 7 days, and even sprayed three times. 30 grams of monopotassium phosphate should be added to each bucket of water to prevent premature aging and red stem blight caused by potassium deficiency. For the control of brown wilt disease, it is recommended to spray with 1000-fold solution of Yiwei, 2000-fold solution of Ruimiaoqing, and 1000-fold solution of Keyingling at intervals of 7 days.
