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.

Detailed Explanation of Key Techniques for Harvesting and Processing Polygonatum
Polygonatum can be harvested in either spring or autumn, with the best quality obtained from harvests in late autumn and early winter. After digging, remove the stems, leaves, fibrous roots, soil, sand and impurities; large ones can be split into 2 or 3 sections and placed in a steamer or wooden rice steamer to steam for about 12 hours, until they appear glossy and moist, then take them out and sun-dry or oven-dry (requires no smoke and low heat); or place them in water, boil, then remove and sun-dry or oven-dry. However, processing by the steaming method is better (after steaming it is prepared Polygonatum, while after boiling in water and sun-drying it is raw Polygonatum).
