Detailed Explanation of Chemical Control Methods for Oyster Mushroom Pests and Diseases
1. Lime: When fermenting the raw materials, add 4%-5% quicklime powder for high-alkali treatment to improve disease resistance; treat the mushroom house walls and mushroom racks with concentrated limewater; after harvesting mushrooms, spray with the supernatant of limewater, which helps prevent disease and increase yield; when there is localized damage from wood (green) mold, sprinkle lime powder on the contaminated areas to control its spread, etc. 2. Sulfur: Before bringing materials into the mushroom house, fumigate and disinfect with sulfur at multiple points, at a dose of 5 grams per cubic meter. 3. Formaldehyde: When mushroom bags are locally infected with Trichoderma and other contaminating fungi, apply a 2% formaldehyde solution.

What are the main pest and disease control methods for mushroom sheds?
With the development of the vegetable basket project, the demand for edible fungi has increased accordingly, but pest damage inside mushroom sheds has created major obstacles to the development of edible fungi. To alleviate this contradiction, the main pests in mushroom sheds and their control methods are introduced here. 1. Mushroom flies The larvae, also called fungus maggots, mainly feed on the fruiting bodies, creating tunnels that affect quality, and the wounds they cause are also very easily infected by pathogens, leading to rot. Different methods should be used to control mushroom flies at different stages. If large numbers of fungus maggots occur before mushroom emergence, dichlorvos can be used at 0.90 kg

What are the main pests and diseases of the Ferula mushroom? Detailed explanation of control methods
I. Infection routes of pests and diseases 1. Natural spread During the process of spawn production and cultivation of edible fungi, the slightest negligence allows pathogen spores to invade the spawn and culture bags, while pests lurk in waste materials, weeds and dead branches and fallen leaves around the mushroom house, developing, laying eggs and reproducing, seriously harming edible fungus production. 2. Seed-borne infection The mother spawn, stock spawn or cultivation spawn used, without strict inspection, is mixed with contaminating fungi and pests; using such spawn for production leads to complete infection. II. Diseases and their control 1. True

Hydrangea Pest and Disease Control Methods and Key Technical Points
When humidity is high, temperatures are high, and ventilation is poor, the plant is prone to aphid damage. Control methods: ventilate promptly. In severe cases, spray with 1500-fold diluted Mieyaling solution. In mild cases, they can be removed by hand with a brush. Spraying with cigarette butt or chili pepper water is also effective. For its control methods, refer to those for roses.

Symptom Identification and Control Methods of Hydrangea Viral Disease
Also known as hydrangea ringspot virus disease and hydrangea mosaic disease. Found sporadically in Beijing, Henan, Hebei and other places. It harms hydrangeas, making the plants short and small, with small and pale flowers, reducing their ornamental value. In some places, horticultural cultivation appreciates its diseased beauty, and it is called variegated-leaf hydrangea. Symptoms are a systemic disease; infected plants are thin and weak as a whole, with pale colors in branches, leaves and flower clusters, appearing pale green under a light pinkish-white covering; the leaves have irregular pinkish-white patches mixed into the pinkish-green, with clear boundaries separated by leaf veins; the leaf margins are white. In early spring and winter in the greenhouse

Symptom Identification and Control Methods for Hydrangea Bud Blight
Hydrangea bud blight is also known as hydrangea gray mold. It damages the buds and flowers of the plant. Symptoms: In field-grown plants, it easily occurs in dense spherical flower clusters, causing them to develop water-soaked rot. In greenhouse cultivation, buds are prone to turning black and withering. Pathogen: The pathogen is Botrytis cinerea Pers., belonging to the Deuteromycotina, Hyphomycetes, Moniliales, genus Botrytis. Disease pattern: The pathogen overwinters as mycelium in diseased plant debris. In the following spring, it produces conidia

Symptom Identification and Control Methods of Hydrangea Ringspot Virus
[Distribution and Damage] Hydrangea (Hydrangea macrophylla), also known as bigleaf hydrangea, is a deciduous shrub planted throughout China. Many viruses infect it, with ringspot being the most common. It is generally latent; severely affected plants are stunted with few or no flowers. [Symptoms] Leaves are crinkled, and stems sometimes show necrotic spots. In inoculated diseased plants, old leaves develop chlorotic spots, brown ringspots, or oak-leaf patterns. [Pathogen] The virus HyRSV, also belonging to the potato virus Y group. Particles are filamentous, measuring 47

What are the control methods for gray mold on hydrangea?
In Zhejiang, Shanghai, Jiangsu, Hebei, Beijing and other hydrangea native areas and introduction areas, it occurs to varying degrees.
