What are the control methods for arrowhead leaf spot disease?
1. Symptoms This disease mainly damages leaves and leaf stalks. The leaf spots are yellowish-brown to brown, polygonal, elliptical or irregular in shape, slightly zonate, surrounded by a yellow-green or green-brown halo; the spots sometimes merge with one another into large lesions, and in severe cases the leaves turn yellow and wither. On leaf stalks, the disease often produces short, streak-like brown spots, and under high humidity a gray mold grows on the surface of the spots. 2. Transmission route and disease pattern This disease is caused by infection by the fungus Cercospora sagittariae of the subphylum Deuteromycotina. The pathogen mainly overwinters as mycelium and conidiomata on diseased plant residues

Detailed Explanation of Arrowhead Seed Retention Methods and Technical Key Points
Before collecting seeds, a seed retention field must be selected. Choose a high-yielding field plot with pure varieties, robust growth, light pests and diseases, and few bolting and flowering plants for seed retention, and harvest when the aboveground parts have completely withered. After harvesting, select corms that conform to the characteristics of this variety, are relatively large, heavy, and have relatively curved terminal buds as seeds. Curved terminal buds are conducive to nutrient accumulation and are not easy to sprout. The selected seed corms should have their terminal buds broken off, with a small part of the upper corm attached. That is, pour the arrowhead terminal buds into a 600-fold solution of 50% carbendazim and soak for 20-25 minutes, then remove

What are the control methods for arrowhead brown spot?
1. Symptoms Arrowhead brown spot mainly damages leaves and leaf stalks. Leaf spots are dark brown and slightly round, later turning grayish-white in the center, with a clear boundary between diseased and healthy tissue. When the disease is severe, the spots are densely packed and merge into patches, causing the leaves to turn yellow and wither. Leaf stalk spots are nearly spindle-shaped, with the diseased area slightly sunken. When the spots expand around the stalk and merge, the leaf stalk breaks and falls over. When humid, a faintly visible thin white mold layer grows on the surface of the diseased area. 2. Transmission route and disease pattern This disease is caused by infection by the fungus Pseudocercospora sagittariae, a member of the Deuteromycotina. The pathogen overwinters as mycelium or conidiomata on corms or diseased residues,
