What are the control methods for jujube fruit shrinkage disease?
1. Symptoms: When jujube fruit shrinkage disease occurs, a pale yellow halo (ring) first appears on the shoulder or waist of the fruit, gradually expanding into irregular sunken lesions; the peel becomes water-soaked and infiltrated, with scattered needle-like round brown dots, and the flesh becomes earthy yellow, soft, spongy and necrotic; the fruit shrivels, tastes bitter, and is unfit to eat. 2. Disease pattern: Preliminary research has determined that jujube fruit shrinkage disease is a bacterial disease, and the pathogen mainly overwinters on fallen diseased fruit. It generally spreads and infects jujube fruit during the fruit coloring and ripening stage; the pathogen enters through fruit wounds via wind and rain or directly penetrates the peel.

What are the main storage-period diseases of garlic scapes and garlic bulbs?
In Jinxiang County, Shandong Province, the garlic planting area has been around 500,000 mu in recent years, accounting for 40% of the county's cultivated land area. The county has 700 large and small constant-temperature warehouses, with a storage capacity of 450,000 t. Every year from late April to early-to-mid May, garlic scapes and garlic bulbs are harvested in a concentrated period. Apart from a small amount consumed locally or shipped out, most of the garlic scapes and garlic bulbs are stored. Losses occur during storage, and rot caused by various diseases is the main cause of loss during the storage of garlic scapes. 1 Diseases of garlic scapes during storage 1.1 Gray mold 1.1.1

Practical Methods of Using Garlic to Prevent and Treat Fish Diseases
1. Treating enteritis: For every 100 kg of fish, use 0.5 kg of garlic bulbs, plus 0.3 kg of table salt, mix with feed and feed to the fish for 3-6 consecutive days. 2. Treating hemorrhagic disease: For every 10,000 fish, use 0.25 kg of garlic bulbs, 4 kg of alligator weed (fresh), and 0.2 kg of table salt, grind together with soybean cake and feed, twice a day for 4 consecutive days. 3. Treating dropsy (scale-standing disease): Add 0.25 kg of mashed garlic bulbs to every 50 kg of water, and soaking the diseased fish several times gives a good therapeutic effect. 4

How to prevent and control rice diseases? Kejie Town in Changning County strengthens unified prevention and control
In June, continuous rainfall in Kejie Town, Changning County, caused bacterial leaf streak to occur to varying degrees in more than 8,000 mu of high-quality rice across the town. The town quickly organized agricultural science personnel, taking villages as units and focusing on high-quality rice demonstration plots, assigning two technicians from each village to go deep into farming households to provide scientific and technological guidance, fully launching a wave of unified prevention and control of rice, mainly targeting bacterial leaf streak. At the same time, a 200-mu high-quality rice demonstration area was established in the two villages of Kejie and Dadi, with 20 yuan per mu in unified prevention and control subsidy funds, and electric sprayers were used uniformly for prevention and control. As of

Key rice diseases to focus on controlling in Guangdong currently
Bacterial leaf streak, rice blast, sheath blight and bacterial leaf blight are the four major diseases in late rice production in Guangdong, mainly damaging the leaves of plants in the early and middle stages of rice growth. The coastal typhoon-prone rice areas of our province are frequent-occurrence areas of bacterial leaf streak, while hilly and mountainous areas are mainly affected by rice blast and bacterial leaf streak. The occurrence periods, characteristics and control methods of bacterial leaf streak, rice blast and sheath blight are briefly described as follows: Bacterial leaf streak. Rice bacterial leaf streak has shown a spreading trend in Guangdong in recent years. The disease starts at the seedling stage and breaks out severely at the young panicle differentiation stage. Ty

Occurrence of Pests and Diseases in Rice Seedbeds and Current Control Methods
During the rice seedbed stage, aphids, thrips, and damping-off disease mainly occur, harming the growth of rice seedlings. Adult and nymph rice thrips often gather at the leaf auricle, ligule, and inside the central leaf to cause damage; the affected parts first show small yellow-white spots, after which mottled white patches appear on the leaf surface. Affected seedlings recover green slowly, become stunted and fail to grow, appearing as if "stuck in the clump." Damping-off disease mostly occurs in wet (semi-dry) seedling nurseries and dry seedling nurseries, causing seedling death. Because temperatures in early to mid-April are unstable, aphids, thrips, and damping-off disease are prone to occur, affecting full, uniform, and strong seedlings. Agricultural technology centers of all townships and subdistrict offices are requested to strengthen water

Winter control of rice pests and diseases can yield twice the result with half the effort
In winter, rice pests and diseases are in a dormant state: pests stop feeding and pathogens stop infecting. If farmers seize this favorable opportunity to carry out control, they can achieve twice the result with half the effort. 1. Dispose of diseased rice straw. Diseased straw is the overwintering site for the pathogens of rice bacterial leaf streak, bacterial blight, rice blast and many other diseases, and is the main source of infection the following year. Before the end of March, farmers can compost diseased straw at high temperature, or process it as feed or fuel, which can greatly reduce the number of pathogens. For diseased rice straw that cannot be fully processed before the end of March,

Disease Prevention and Treatment Methods and Technical Key Points for Turtles
Parotitis Cause: The pathogen is Aeromonas punctata subsp. punctata. The main cause is water pollution. Symptoms: Affected turtles move slowly, often raise their heads and necks high in water or on land, with abnormally swollen necks and bulging hind limb fossae. There is gas under the skin, and the limbs are swollen; in severe cases, blood flows from the mouth and nose. Prevention and treatment: Inject streptomycin sulfate at 100,000-120,000 units per kg of turtle body weight. Inject once a year. Routinely use 30 mg/L furazolidone every 2-3 months

Diagnosing Fish and Shrimp Diseases by Color and Disease Prevention and Treatment Methods
After fish and shrimp become ill, a certain part of their body or a certain organ takes on a distinctive color, which becomes a characteristic symptom of the disease they are suffering from. Animal medicine workers use this to name the disease for identification, prevention and treatment. This is a commonly used method in the animal medicine field, briefly described as follows: 1. "Red" diagnosis (1) Eel red spot disease is caused by Pseudomonas anguilliseptica, mainly harming Japanese eels; European eels are not easily infected. Symptoms: pinpoint hemorrhages appear on the lower jaw, operculum, base of the pectoral fins and the body surface of the abdomen, with death occurring within 1 to 2

What types of bacterial diseases do koi carp get?
① Red-skin disease (hemorrhagic disease) Symptoms: extensive hyperemia of the epidermis. There are no large ulcers or swellings on the body surface, only obvious redness at the fin bases, nostrils and other areas, with visible blood streaks. In the later stages it is accompanied by ascites and gill rot. Pathogen and cause of infection: caused by Pseudomonas fluorescens, highly contagious. Unsanitary water, injuries, and spoiled feed can all cause this disease, and it occurs in all four seasons. Treatment: soak the sick fish in the original tank (pond) with a 2 ppm furacilin solution, soaking for several consecutive days
