A Detailed Explanation of the Harm and Control Methods of Angelica Sclerotinia Rot
The pathogen of Angelica sclerotinia rot (Sclerotinia SP) is a fungus of the genus Sclerotinia in the subphylum Ascomycotina. The sclerotia are borne on the plant surface or on aerial hyphae in the internal cavities of plant organs, resembling mouse droppings, irregular in shape, and composed of hyphae. 1. Harmful symptoms: It mainly harms roots and leaves. In the early stage of the disease, the leaves turn yellow; in the later stage, the plant wilts, and the root tissue rots to form cavities containing multiple black, mouse-dropping-shaped sclerotia. 2.

Harm and Control Methods of the Licorice Seed Chalcid
Adults lay eggs on the seed coat of green fruits; after the larvae hatch, they immediately bore into and feed on the seeds, and pupate inside the seeds. After the adults emerge, they bite through the seed coat and escape. The infested seeds are eaten out into empty shells, and small round emergence holes are left on the seed coat and pods. This pest has a great impact on yield. Control methods: ① In winter, clear away residual leaves to reduce the source of the pest. ② Before sowing, the seeds must be treated, either by removing the insects or by dressing the seeds with carbaryl powder. ③ During the occurrence period, especially the green fruit stage, spray with pesticide.

What Harm Can Herbicide Damage Cause to Schisandra chinensis
I. Soil-residual herbicide damage 1. Symptoms. In the middle of the growing season the leaves wilt, recovering their upright posture in the morning and evening; the plants become rigid and stop growing, similar to drought, and the root system develops slowly. 2. Cause. Damage from triazine, sulfonylurea, imidazolinone and similar herbicides. 3. Preventive measures. (1) Any farmland that has been treated with long-residual herbicides such as triazines, sulfonylureas and imidazolinones must not be planted with Schisandra chinensis within two years. (2) If symptoms are found, drench the roots with COMPO Kapco 500 times dilution, and spray the foliage with Bihu, Yecui
