Symptoms and Control Methods of Polygonatum Leaf Spot Disease
The disease begins in April to May. On affected leaves, elliptical or irregular lesions first appear at the leaf tip, with brownish outer edges and pale white centers; the disease spreads downward from the lesions, causing the leaves to wither and die. The disease is more severe during the rainy season. Control methods: 1) After harvest, clean the field and garden, gather the dead branches and diseased plant debris and burn them to eliminate the overwintering pathogen. 2) Before the disease occurs and in the early stages, spray 1:1:100 Bordeaux mixture, or 50% Tuzet (thiram) 1000x solution, once every 7 to 10 days, for 3 to 4 consecutive sprays.

Propagation Methods and Cultivation Techniques of Polygonatum
Propagation methods: Propagated by rhizomes and seeds, mainly by rhizomes. 1. Site selection and land preparation: Choose loam soil with deep, fertile, loose and moist soil layers. Apply 2500 kg of decomposed compost or barnyard manure per 667 sq m, plow deeply 25-30 cm, then break up the soil finely and level it, and make beds 1.2 m wide. 2. Rhizome propagation: In late autumn or late March of early spring, dig out the underground rhizomes, cut them into small sections with 2-3 nodes, and air-dry them for half a day or 1 day to let the wounds heal. Open furrows at a row spacing of 20-25 cm, with a furrow depth of 6 cm, and at a plant spacing of 10-15

Harvesting, Processing Methods and Medicinal Effects of Polygonatum
Harvesting and processing: Polygonatum grown from transplanted rhizomes is harvested after 1 to 2 years, while plants grown from seed are harvested after 3 to 4 years. In late autumn or early spring, dig out the rhizomes, wash off the soil, remove the fibrous roots and diseased scars, steam for 10 to 20 minutes (until thoroughly steamed), take them out and dry them in the sun, kneading them while drying; after 7 to 10 days of sun-drying they will be dry. Medicinal effects: Polygonatum is sweet in flavor and neutral in nature. It enters the spleen, lung and kidney meridians. It has the effects of tonifying the spleen and moistening the lungs, nourishing yin and promoting fluid production, tonifying the middle and replenishing qi, and strengthening the tendons and bones. It treats consumptive damage with alternating cold and heat, pulmonary tuberculosis with coughing of blood, pulmonary tuberculosis with dry cough and no phlegm, diabetes, hypertension, and post-illness bodily

Methods and Technical Key Points for Pest and Disease Control in Polygonatum (Solomon's Seal)
Diseases include black spot disease, in which irregular yellowish-brown spots appear on the leaves starting from the leaf tip, with a purplish-red edge at the boundary between the diseased and healthy tissue, after which the spots spread downward and the leaves turn withered and yellow. For control, spray with a 50% Tuzet (thiophanate) 1000-fold dilution, applying the spray once every 7-10 days for 2-3 consecutive applications.

Methods and Technical Key Points for the Prevention and Control of Pests and Diseases in Polygonatum
(1) Black spot disease occurs mostly in spring, summer and autumn, and damages the leaves. Control methods: clean the garden at harvest time to eliminate diseased plant residues; in the early stage, spray 1:1:100 Bordeaux mixture once every 7 days, for 3 consecutive times. (2) White grubs damage plants in the larval stage, attacking the roots, biting off seedlings or gnawing the seedling roots, causing broken seedlings or cavities in the roots, and the damage is severe. Control methods: seed dressing with 75% phoxim emulsifiable concentrate at 0.1% of the seed amount; or during the field occurrence period, drench with 90% trichlorfon at 1000 times dilution.
