Symptoms mainly affect the leaves and petioles. The lesions are nearly round and dark brown. The middle part of the plaque turns to grayish white. The sick and healthy parts are clearly defined. When the disease is severe, the lesions are densely covered and become plaques, eventually causing the leaves to become yellow and dry. The petiole lesions were nearly spindle-shaped and slightly sunken. The lesions spread around the handle and were contiguous. The petioles eventually collapsed. During the wet period, the surface of the diseased part of the white mold layer is faintly visible.
Control methods (1) Breeding resistant varieties.
(2) Strengthen fertilizer and water management, increase application of organic fertilizers and phosphorus and potash fertilizers, and avoid partial application of nitrogenous fertilizers; According to the budding period of sagittaria, from leafing to the beginning of bulbous enlargement and fertility in bulb formation, it is necessary to manage the water layer well to avoid long-term deep irrigation. .
(3) 70% Thiophanate-methyl WP 1000-fold plus 75% chlorothalonil wettable powder 1000-fold, or 50% Sulphur Suspension or 36% methyl sulphur Ferulicose suspension 500-600 times liquid, or 1:1:100 Bordeaux mixture. Besides the Bordeaux mixture, the above-mentioned agents can be added with 0.2% detergent to increase exhibitionability, once every 7-10 days, continuous control 2- 3 times.

α- GPC is a water-soluble substance with two fatty acids removed from the main phospholipid PC (phosphatidylcholine) constituting the cell membrane.α- GPC is a water-soluble substance with two fatty acids removed from the main phospholipid PC (phosphatidylcholine) constituting the cell membrane.


Originally widely existing in organisms, it is one of the body components existing in human breast milk and body fluids. Research in the food industry shows that GPC can be obtained by removing fatty acids (deacyl) in the structure with PC in soybean lecithin as raw material. In the revision of food and drug classification in 2009 α- GPC (sn-glycerol-3-choline phosphate) is defined as food.


Purpose: brain health food. It is clinically used to prevent and treat atherosclerosis, fatty liver, neurasthenia and malnutrition. It can also be used as an additive for food, cosmetics and pharmaceutical excipients. It can be transformed into hemolytic lecithin by phospholipase a.


Prevent choline deficiency, increase neurotransmitters and promote the secretion of growth hormone. Although both eggs and eggs contain choline, it is confirmed that the uptake in the form of GPC is faster than the absorption through the portal system, and it is easier and more efficient to convert to choline. And GPC is one of the few five that can pass through the blood-brain barrier, so it can be quickly converted from choline to acetylcholine.
