Identification and Control Methods for White Grub Infestation in Codonopsis pilosula
Belonging to the order Coleoptera, family Scarabaeidae. It is the larva of the scarab beetle, mainly active in the soil, damaging the roots of Codonopsis pilosula. White grubs generally have one generation per year, with larvae or adults overwintering in the soil. After temperatures rise in the following spring, white grubs gradually move upward in the soil; when the soil temperature reaches above 15°C, they move into the topsoil layer above 10cm to feed. When summer temperatures rise and the soil dries out, they descend to deeper soil layers and stop feeding or moving. In autumn they return to the topsoil layer to be active, and after October they successively burrow down below 30cm to overwinter.

Symptom Identification and Control Methods for Licorice Gray Leaf Spot
It damages the leaves, forming nearly round brown lesions with gray centers. Control methods: (1) Clear the garden in winter and dispose of plant debris. (2) During the disease period, spray 1:1:120 Bordeaux mixture or 70% thiophanate-methyl wettable powder at 1500-2000 times dilution.

Symptom Identification and Control Methods of Lily Blight
Blight is an important disease of lilies, widely distributed, occurring mostly in the south, with occasional outbreaks in protected cultivation in the north. Usually 5%-10% of plants are diseased, affecting lily production to a certain extent; in severe cases it can reach over 30%, causing plants to die in patches and significantly affecting lily yield and quality. Symptoms: This disease can infect all parts of the lily. When the stem is infected, it initially shows water-soaked light brown to greenish-brown rot, gradually spreading upward and downward, causing the plant to wither and die or topple. When leaves are infected, small water-soaked spots initially appear, later developing into grayish-green to dark green large spots, ultimately causing

Symptom Identification of Several Major Diseases of Oyster Mushrooms
(1) White rot: The pathogen is Mycogone perniciosa, which harms the fruiting bodies. After the mushroom bodies are contaminated, it causes rot and produces a putrid odor. (2) Brown spot disease: The pathogen is Verticillium fungicola. After its spores infect the fruiting bodies of oyster mushrooms, brown spots first form on the caps, gradually expand, and produce grayish-white depressions. After the mushroom bodies are damaged, they become deformed, and the stipes become swollen or curved, but they do not rot, and finally dry up and die. (3) Mucor soft rot: The pathogen is Mucor. It generally occurs when the fruiting bodies are fully mature

Identification and Control Methods of Common Oyster Mushroom Diseases
Why do some oyster mushrooms grow small white lumps in the later stage of growth? This occurs more in black varieties and rarely in grayish-white varieties. The same cultivation method and substrate were used. Why does this happen? How should this contaminant be controlled? Every stage of oyster mushroom production can suffer from contaminant contamination, and it must be controlled promptly. The common contaminants are mainly the following: (1) Bacteria mostly occur on the slant of mother cultures, while the harm to stock cultures and cultivation cultures is relatively mild. Bacterial contamination is characterized by rapid reproduction, generally becoming visible 10 to 24 hours after inoculation.

Identification and Control Methods for the Lily Pest Cotton Aphid
Its harm to plants is second only to the green peach aphid, and it also has many host species, mainly chrysanthemums, lilies, and others. Morphological features: female aphids are winged or wingless, extremely small in size, initially pale yellow, later black. Legs and antennae are yellow-white. Male aphids are all wingless, 1/3 shorter than female aphids, and similar in color. Eggs are oval, yellow when first laid, turning black when hatching. Nymphs are gray-white at first, later turning yellow. When mature, those with wing buds on the thorax and back are winged mother aphids, while those without wing buds are wingless mother aphids. Damage habits: the cotton aphid can produce 20 generations a year, overwintering as eggs on plant

Symptom Identification and Control Methods of Lily Gray Mold
Lily, belonging to the genus Lilium in the family Liliaceae, is a perennial herbaceous plant. In recent years, lily cultivation has been severely threatened by diseases, mainly including lily gray mold (leaf blight), Phytophthora blight, basal rot, and viral diseases. These diseases often occur together, compounding the damage. Among them, lily gray mold has the greatest impact on lily growth and cut flower quality, and can even affect the propagation of lily bulbs. Lily gray mold is a commonly occurring disease. It mainly damages leaves, but can also infect stems and flowers. Infected lily leaves and floral organs frequently develop symptoms such as leaf scorch, deformed flower buds, and wilting petals in the later stages.
