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

The Harm and Control Methods of the Spruce Bark Beetle
The spruce bark beetle (Ips typographus Linnaeus) belongs to the order Coleoptera, family Scolytidae. In China it is distributed in Northeast China, Inner Mongolia, Sichuan, ** and other places, mainly damaging spruce and Korean pine, and is a destructive pest in some spruce forest areas. Damage characteristics: it bores galleries between the phloem and sapwood of pine trees, and the galleries are compound longitudinal galleries. It can also directly attack healthy trees, and often occurs together with other bark beetles, causing trees to die in patches. Morphological characteristics: adult body length 4.0-5.5 mm,

A Detailed Guide to the Harm Caused by the Jujube Leaf Beetle and Its Control Methods
The jujube leaf beetle belongs to the order Coleoptera, family Chrysomelidae. The larvae and adults of this insect damage jujube leaves and tender shoots. In outbreak years, the leaves are eaten bare, leaving only the bare fruiting branchlets, which greatly affects yield. The peak damage period for this insect is from mid-April to mid-May. Both larvae and adults damage jujube leaves, tender shoots, flower buds and flowers. Control methods: spraying mainly for flower protection is the primary approach. During the occurrence period of larvae and adults, spray 90% trichlorfon at 1500 times dilution or deltamethrin at 1.5 ten-thousand to 1.6 ten-thousand times dilution; generally the insecticidal effect is very good.

Detailed Explanation of the Harm and Control Methods of Angelica Powdery Mildew
The pathogen of Angelica powdery mildew (Erysiphe sp.) is a fungus of the genus Erysiphe in the subphylum Ascomycotina. The cleistothecia are clustered, embedded in the mycelium, spherical or flattened spherical, black or dark brown. The cleistothecia contain 3-6 asci. The asci are nearly spherical, oval, colorless, with short stalks, thick-walled, and contain 3-6 ascospores. The ascospores are elliptical, colorless and transparent, single-celled. 1. Harmful symptoms: It damages the leaves. In the early stage of the disease, grayish-white powdery lesions appear on the leaf surface, which then expand and merge into large spots,

Harm and Control Methods of the Lingzhi Mushroom Fly
The large mushroom fly, scientific name Neoempheriasinica, also known as the Chinese new mushroom gnat, belongs to the order Diptera, family Mycetophilidae. This insect is mainly distributed in Jiangsu, Hubei, Shanghai, Beijing and other places, and occurs mostly in the relatively damp and shady places of air-raid shelters and mine tunnels. In spring and autumn, the larvae of this insect damage edible fungi such as lingzhi (Ganoderma lucidum), oyster mushroom, shiitake, wood ear, lion's mane, and enoki mushroom. The damage is characterized by the larvae feeding on lingzhi mycelium and fruiting bodies, leaving boreholes at the damaged sites, and also excreting mucus and frass that contaminate the fungal bodies, lead

Harm and Control of Caloglyphus shanghaiensis in Edible Fungi
Caloglyphus shanghaiensis (CaloglyphusShanghaiensis) belongs to the family Acaridae, genus Caloglyphus. Within the genus Caloglyphus, other species related to edible fungus production include Caloglyphus kunshanensis, Caloglyphus mirabilis, Caloglyphus mycophagus, Caloglyphus coprophilus, Caloglyphus hughesi, and Caloglyphus oudemansi. Among these, Caloglyphus shanghaiensis and Caloglyphus kunshanensis are the more prominent. (1) Damage characteristics: Caloglyphus shanghaiensis not only feeds on edible fungus mycelium and fruiting bodies, but also carries and spreads contaminant microorganisms, affecting mycelial growth and reducing the yield and quality of edible fungi. Caloglyphus kunshanensis (

Harm and Control Methods of the Mold Mite in Edible Fungi
Tyrophagus putrescentiae belongs to the family Acaridae, genus Tyrophagus, and is distributed throughout the country. (1) Harm characteristics This mite is one of the most important pest mites of edible fungi. It frequently occurs in mushroom spawn bottles, mushroom beds, and shiitake mushroom blocks, and also damages straw mushrooms and oyster mushrooms. It also commonly occurs in large numbers in edible fungus cultivation materials such as rice straw, cottonseed hulls, and barnyard manure, especially in humid environments, where it reproduces quickly and occurs in large numbers. After the edible fungus mycelium is fed upon, it breaks apart and gradually tends toward aging and decline.

The Harm and Prevention and Control Methods of Orchid Virus Diseases
Viruses are relatively primitive organisms. They have no cellular structure and can only replicate by parasitizing host cells. Once infected, there is generally no specific drug for treatment, so viral diseases can only be prevented. Prevention can be achieved by improving environmental sanitation and raising cultivation techniques. More than 20 kinds of viruses that can infect orchids have been discovered so far. The more common ones include Cymbidium mosaic virus (CyMV), Cucumber mosaic virus (CMV), Dendrobium mosaic virus (DeMV), Cymbidium ringspot virus (CyRV), and others.

Harm and Control Methods of Drosophila melanogaster on Ganoderma lucidum
Drosophila melanogaster belongs to the order Diptera, family Drosophilidae. It is mainly distributed in the southern provinces of China, where it damages edible fungi such as Ganoderma lucidum, wood ear fungus and silver ear fungus, causing serious damage. Damage characteristics: the larvae of Drosophila melanogaster feed on Ganoderma lucidum mycelium and the growing substrate, causing the substrate to become waterlogged and rot, which can lead to bacterial invasion. The adults can carry molds, nematodes, mites and other pests and diseases, aggravating the occurrence of pest damage and seriously affecting the yield and quality of Ganoderma lucidum. Morphological characteristics: the adult is relatively small, about 4
