Control Methods and Key Technical Points for Pests and Diseases of Honeysuckle
Honeysuckle, also known as silver flower or Japanese honeysuckle flower, is the dried flower bud of plants in the Caprifoliaceae family and several plants of the same genus. It has the function of clearing heat and detoxifying, and is suitable for diseases such as seasonal febrile diseases with fever, wind-heat common cold, sore throat, pneumonia, dysentery, and carbuncles, swellings, sores and ulcers. It is a commonly used traditional Chinese medicinal material, with annual national sales reaching 5.5 to 6 million kg. Honeysuckle is produced in most provinces and regions across the country, among which Shandong, Henan and Guangxi have the largest output and the best quality. Honeysuckle has relatively many pests and diseases, and doing a good job of prevention and control is the key to increasing honeysuckle yield and ensuring market supply

What are the methods for controlling pests and diseases of honeysuckle?
The main pests and diseases of honeysuckle are honeysuckle brown spot disease, which harms the leaves and occurs from July to August. After the disease develops, the spots on the leaves are round or polygonal due to the restriction of leaf veins, yellow-brown, and in humid conditions there is a gray mold-like substance on the underside of the leaves. Effective control methods are to promptly remove diseased branches and leaves, strengthen cultivation management, and increase the application of organic fertilizer to enhance disease resistance. In addition, spraying Bordeaux mixture at a ratio of 1:1.5:200 in the early stage of the disease can effectively control brown spot disease. The main insect pests of honeysuckle are aphids and coffee tiger longhorn beetles. To control aphids, 40% dimethoate emulsifiable concentrate 10

Occurrence Patterns and Integrated Control Methods of Pests and Diseases in Goji Berry
Goji berry is a deciduous shrub of the genus Lycium in the Solanaceae family. Its fruit is called goji berry (Lycii Fructus), and its root bark is called Digupi (Lycii Cortex); both can be used as medicine. The tender stems and leaves are eaten as vegetables. It is distributed throughout China, mostly in the wild. The related species Lycium barbarum (Ningxia goji) is mostly cultivated; its fruit is called Xi goji or Gan goji and is used medicinally, mainly produced in Ningxia, Gansu and Inner Mongolia. Goji berry suffers from pests and diseases at every stage of growth, causing great economic losses to production. The occurrence and control methods of goji berry pests and diseases are introduced as follows: 1 Diseases 1.1 Black fruit disease (anthracnose) Main

Common Pests and Diseases of Goji Berry and Their Control Methods
1. Goji berry black fruit disease, also known as anthracnose. It damages fruits and leaves. ① When fruits are affected, circular irregular brown slightly sunken lesions first appear on green fruits, with small black dots arranged in concentric rings, and some lesions show orange-red sticky substance. In the later stage, diseased fruits turn black, become mummified and drop early. ② When leaves are affected, initially yellow small spots appear, later expanding into irregular lesions with reddish-brown edges, and in the later stage small black dots appear on the lesions, some of which rupture and perforate. The disease is severe in July to August when temperature is high and humidity is high. Control methods: ① During winter pruning,

Methods and Technical Key Points for the Prevention and Control of Licorice Pests and Diseases
The main diseases of licorice are rust, powdery mildew and brown spot. Licorice rust mainly damages the leaves and tender stems of the plant; the back of infected leaves produces yellow-brown blister-like lesions on one side, and after the epidermis ruptures, brown powder is released. Prevention and control method: burn the leaves of diseased plants. In the early stage of the disease, treat with a 1000-fold dilution of Fenxiuning; you can also use 0.3 degrees Baume lime sulfur mixture, or a 500-fold dilution of 65% wettable zineb, or a 200-fold dilution of dithianon sodium for spray control, spraying once every 7 to 10 days, and 2 to 3 consecutive sprays are sufficient. Licorice brown spot is also called

What are the common pests and diseases of licorice (Glycyrrhiza) and their control methods?
(1) Rust: in the early stage of the disease, spray with 25% triadimefon wettable powder at 1000 times dilution or 97% dinocap at 300 times dilution for control, once every 7-10 days, for a total of 2-3 sprays. (2) Brown spot: spray once with 1:1 Bordeaux mixture before the disease occurs; in the early stage of the disease, choose 70% thiophanate-methyl wettable powder at 2000 times dilution or 75% chlorothalonil at 500 times dilution for spray control, once every 7-10 days, for a total of 2 sprays. (3) Aphids: during the occurrence period, spray-kill with 40% dimethoate emulsifiable concentrate at 1500 times dilution.

Methods for the prevention and control of Angelica sinensis pests and diseases and key technical points
(1) For stem nematode disease (má kǒu bìng), the peak periods of occurrence are in mid-April, mid-June, early September and early November after transplanting; it damages the roots, and an abundance of soil-dwelling pests favours its occurrence. Control methods: ① Per mu, use 3 kg of 3911 granules mixed evenly with 15 kg of fine soil, or 0.5 kg of 20% methyl isofenphos emulsifiable concentrate mixed with 2.5 kg of water and sprayed onto 15 kg of soil and mixed evenly, then broadcast and turn into the soil; ② Regularly drench the roots with a broad-spectrum, long-lasting insecticide; per mu use 250 g of 40% carbendazim suspension concentrate or 600 g of thiophanate-methyl plus

A Detailed Guide to the Prevention and Control of Pests and Diseases on Japanese Honeysuckle (Lonicera japonica)
Anthracnose occurs frequently in summer and can be controlled by drenching with a 500-1000 times dilution of wettable Dexon powder. For rust, spray a 200-250 times dilution of the technical-grade dithianon sodium (you may add 50-100 g of washing powder to 50 kg of the spray solution as a sticker). Insect pests include aphids, longhorn beetles and others; aphids can be sprayed with a 4000 times dilution of 10% imidacloprid, while longhorn beetles can be sprayed with a 500 times dilution of duomeike (methomyl). Note, however, that toxic pesticides must never be used on Japanese honeysuckle during the bud stage.

Control Methods and Technical Key Points for Physiological Diseases of Oyster Mushrooms
Oyster mushrooms have the characteristics of wide adaptability, strong stress resistance, a wide range of cultivation material sources, simple cultivation techniques, and high economic benefits. In recent years, oyster mushroom production has developed rapidly in our county, but in production, various non-infectious physiological diseases often occur due to poor management, causing yield reductions and directly affecting the economic benefits of oyster mushroom production. Based on many years of production practice experience, we have summarized the symptoms and control techniques of several main physiological diseases that commonly occur in oyster mushroom production. 1. Excessive mycelial growth In oyster mushroom production, excessive mycelial growth often causes the mycelium to become dense

What are the basic methods for diagnosing diseases in raccoon dogs?
(1) General examination includes inquiry, visual inspection, palpation, auscultation, percussion, and olfactory examination. (2) Necropsy technique. The necropsy technique is a method that uses knowledge of pathological anatomy to make an on-site diagnosis based on the pathological changes in the carcass. The necropsy should be performed as soon as possible after the raccoon dog dies, to prevent postmortem changes from affecting the diagnosis. The necropsy is best performed in the pathology room of the animal farm. If conditions do not allow it, and the necropsy must be performed outdoors, choose a place with dry terrain, far from water sources, roads, and residences, and properly dispose of the carcass after the necropsy.
