Symptom Identification and Control Methods of Rust Disease in Codonopsis pilosula
It damages the leaves. The diseased area on the underside of the leaf is slightly raised, forming the uredinium, which later ruptures and releases orange-yellow urediniospores. The disease is most severe from June to July. Control methods: (1) Clear away withered branches and fallen leaves in winter. (2) During the disease period, spray with a 200-fold dilution of 50% dinitro compound or a 400-fold dilution of 97% sodium dithiocarbamate, once every 7 days, for 2 to 3 consecutive applications.

Introduction to the New Codonopsis Variety 92-02
I. Variety Introduction: Codonopsis pilosula is one of the main medicinal herbs in Dingxi City, Gansu Province, with a planting area of about 18,700 hm2 over the years and a total output of more than 30,000 t, accounting for 40% of China's Codonopsis pilosula share. In 2001, Weiyuan County of Dingxi City was named "China's Hometown of Codonopsis pilosula" by the Organizing Committee of the Hometown of Specialty Products of the Chinese Association of Agricultural Science Societies, and the Codonopsis pilosula industry has become one of the important pillar industries of Dingxi City. However, the Codonopsis pilosula currently planted in fields is basically a mixture of multiple types, which has adversely affected yield and quality and severely restricts the sustainable development of the Codonopsis pilosula industry.

Symptoms and control methods of downy mildew in codonopsis (Codonopsis pilosula)
Irregular brown lesions appear on the leaf surface, and a gray mold-like growth (conidiophores and conidia) appears on the underside of the leaves, which can cause the plant to die. Control method: remove diseased plants and fallen leaves and burn them in a centralized manner; during the disease period, spray 300-fold dilution of 40% Shuangyiling or 1000-fold dilution of 70% chlorothalonil, once every 7 to 10 days, for 2 to 3 consecutive times.

What are the control methods for rodent damage to codonopsis (Codonopsis pilosula)?
They begin to damage the seedlings when the seedlings emerge 5 cm above ground. Control methods: (1) Mix 1 part of 3% zinc phosphide with 95 parts of green vegetables, beans, rice, etc.; after mixing well, scatter the bait in the evening in places where rats frequently appear or at their burrows. (2) Mix 1 part of 0.5% bromadiolone evenly with 3 parts of flour, then add cut apple pieces, vegetables, and fried dough sticks (cut into 1 cm pieces) and mix them evenly to coat; this can be placed in the evening in places where rats are frequently active. Alternatively, use 2.5% phorate granules at 1500 g per 667 sq m mixed with 10 kg of fine soil and scatter it along the edges of beds and ridges to drive rats away; be careful not to scatter it on the seedlings.

Symptom Identification and Control Methods of Root Rot in Codonopsis pilosula
The pathogen is a type of imperfect fungus among the fungi, and it is divided into two types: chronic onset and acute onset. In the chronic type, the disease begins in mid to late May. In the early stage of the disease, dark purple lesions appear on the lower fibrous roots or lateral roots, which then turn black and rot. After the disease spreads to the main root, it gradually rots from bottom to top. The remaining unrotted part is mostly a "half-section ginseng," and the area near the rotted part is dark brown. The stems and leaves above ground gradually turn yellow and eventually die. In the acute type, the disease mostly begins in mid to late June. Once the ginseng root is infected, almost the entire ginseng root becomes diseased at the same time

How to grow Codonopsis pilosula? A detailed explanation of the key points of Codonopsis pilosula cultivation techniques
1. Site selection and land preparation For the seedling bed, it is best to choose a sandy loam or humus loam close to a water source, with loose, fertile soil and good drainage, and a shady slope facing away from the sun; for the planting site, a gently sloping field or terraced field with high, dry terrain and good drainage should be chosen, and virgin wasteland as well as flat land are both acceptable, but the soil layer must be deep, relatively fertile, well structured, and easy to cultivate. After the soil is selected, in the winter of the previous year clear the shrubs and weeds from the virgin wasteland, burn them to ash for fertilizer, then deep plow the soil 30 cm, level and harrow it fine, and make raised beds 1.3 m wide
