Sweet, commonly known as bian dou, with aliases huolian biandou, tengdou, yanli dou, quedou, chadou, yueliang cai, belongs to the Dicotyledoneae class. There are also many varieties, such as: white hyacinth bean, purple hyacinth bean, oil bean, snake bean, pig's ear bean (shaped like a pig's ear). It is a perennial, twining vine plant of the genus Lablab in the Fabaceae family. It is a type of legume plant.</p><p></p><p>The pathogenesis of hyacinth bean brown spot disease:</p><p>Hyacinth bean brown spot disease, also known as brown-edged white spot disease, mainly damages leaves. Nearly circular or irregular brown spots appear on the front and back of the leaves, with reddish-brown edges, 1 to 10 mm in diameter, and later the center of the lesion turns grayish-white to grayish-brown. Under high humidity, grayish-black mold-like growth appears on the lesions on the underside of the leaves. The pathogen overwinters in the soil as ascocarps with diseased residues. In the following year, primary infection is caused by ascospores produced by the overwintering pathogen, which spread by wind and rain, and ascospores produced in diseased areas spread by airflow. This disease is a high-temperature, high-humidity disease. Under high-temperature and rainy weather conditions, with a temperature of 20 to 25°C and relative humidity above 85%, it is prone to occur.</p><p>Control methods for hyacinth bean brown spot disease:</p><p>1. Agricultural measures: rotate with non-legume vegetables for 2 years. Plant at a reasonable density, apply more potassium fertilizer, clean the field, and collect and burn diseased residues.</p><p>2. Seed disinfection: pre-soak the seeds in cold water for 4 to 5 hours, then transfer to 50°C warm water for a brief soak of 5 minutes.</p><p>3. Chemical control: apply pesticide promptly at the early stage of the disease. You may choose 80% zineb wettable powder at 500 times dilution, or 45% amobam aqueous solution at 1000 times dilution, or 50% thiram wettable powder at 600 times dilution, or 25% metalaxyl wettable powder at 800 times dilution, or 20% benalaxyl emulsifiable concentrate at 350 times dilution, or 40% fosetyl-aluminum wettable powder at 200 times dilution, or 66.5% propamocarb aqueous solution at 800 times dilution, or 50% captan wettable powder at 450 times dilution, etc. for spraying.
