Pathogen analysis: the pathogen is a semi-known fungus, Subserophyceae, Cyclosporium, and the pathogens survived winters in the soil with mycelia and subsp. Poorly ventilated, moisture-absent nitrogenous fertilizers are prone to overdosing [Pathogen analysis]: The pathogen is a sub-phytosporangia subsp. pleurospora genus, and the pathogens are mycelia and sub-sporophytes on the diseased plant or diseased body. On wintering, conidia spread by wind and rain, warm and humid environment is more severe, and over-application of nitrogen fertilizer can easily lead to disease.
ã€Prevention and control measures】: When the Pachira tree gets sick, it must be promptly cleaned up and destroyed. 2 Increase the application of phosphorus and potassium fertilizer, do not apply partial nitrogen fertilizer, 3 drug treatment or comprehensive prevention and treatment in the early onset of the disease, for the stem disease department can be used drug smear or explosive hair treatment, (30% copper oxychloride 30-50 times Liquid or 50% protection work 50 times liquid or 10% multibacterial copper milk powder 30 times, or 80% anthrax Fome 50 times) to remove diseased leaves lesions, and spray 1-2 times until the condition is controlled Fortune tree various diseases prevention Pachira ash blight: The main harm to the leaves, lesions are amorphous, yellow-white to gray-yellow, the disease is generally not obvious, the temperature of large needle-like scattered small black spots.
[Pathogen analysis]: The pathogen is a semi-known fungus Subphylum fungi, including the major Stenospora spp., Monosporium spp., Lepidium spp., Helminthosporium spp., and Sphaerotheca fulvae. Different types of local pathogens are not the same, the symptoms are gray spots, no rims on the surface, and frequent occurrence of gray spot disease on older leaves.
[control methods]: find the residual disease leaves to be collected and destroyed 2 for fertilizer and water should be good management to enhance plant resistance to disease, reduce the incidence of disease, 3 find the disease early this morning spraying prevention and control of disease. Protect it once in winter and in early spring, and use 50% retired special wettable powder 600-800 times liquid at the beginning of onset, or 30% copper oxychloride suspension + 70% mancozeb wettable Powder (1:1) 800 times, or 40% Triflumone carbendazim wettable powder 800-1000 times, or 50% fluosilazole EC 3000-4000 times, spray once every 10-15 days fortune Tree disease prevention of Pachira virus disease: There are two diseases of Pachira, one is that the leaf margins are obvious defects, which are easily mistaken for mechanical damage. Second, the leaves become deformed, or the page shrinks unevenly. Or the leaf is slightly curled.
Pathogens cannot be identified: If the diseased plants are isolated or destroyed, try them (0.1% soap or 5% chlorothalonil solution 300 times)
Fortune tree diseases prevention and treatment of hairy stem base rot disease: The main harm stem base, the symptoms are: stem base skin color is abnormal (dark gray to gray black), touch feels soft texture, autopsy see gray-brown, wet rot, Expanded deep into the xylem, eventually causing the whole plant to die.
[Pathogen analysis]
The pathogens responsible for the rot disease at the base of Pachira fulgens are fungi, which include the sub-genus Amystis and the genuses of Fusarium and Sporotrichum. The Bureau of Mycorrhizal Diseases inhabits the soil in which the mycelium and its fruit bodies survived from the remains of the diseased body and survived the invasion from the plant wounds. Plant wounds are often susceptible to disease, potting soil is negligible and warm and humid weather is susceptible to disease, and soil miscellaneous fertilizers that are not fully decomposed are susceptible to disease.
[control measures]: Plants should be careful not to hurt the transplanted plants, the liquid base should be used before the colonization of the roots of the stains (permanent potassium permanganate 600 times into the stain 1 hour or 30% copper chloride suspension 600 times liquid For half an hour of infiltration, use 600-1000 times potassium permanganate as the definitive root water for colonization. After colonization and survival, we should regularly or occasionally wet the potassium permanganate 600-1000 times. To completely cut off, for the initial disease of mildly ill strains, a sterile knife can be used to completely scrape off the affected area, and then infiltrate the liquid.
Lincomycin injection
This product is a narrow-spectrum antibiotic with similar effect to erythromycin. It has a good effect on Gram-positive cocci, especially on anaerobic bacteria, Staphylococcus aureus and pneumococci. Its mechanism of action is similar to erythromycin and belongs to bacteriostatic agent. It mainly inhibits the synthesis of bacterial cell protein. Clinically, it is mainly used for various infections caused by sensitive bacteria, such as pneumonia, meningitis, endocarditis, cellulitis, tonsillitis, erysipelas, furuncle and urinary system infection. Because this product can enter bone tissue and has special affinity with bone, it is especially suitable for infection caused by anaerobic bacteria and Staphylococcus aureus osteomyelitis.
Hydrochloric acid products
pharmacological action
This product has strong antibacterial activity against Staphylococcus aureus (including enzyme producing strain), Staphylococcus epiphyte, group a hemolytic streptococcus, pneumococcus and grass green Streptococcus. Most diphtheria bacilli, tetanus bacilli and Aeromonas aeruginosa are also sensitive to this product. Most enterococci are resistant to this product.
Clinically, it is mainly used for respiratory tract infection, osteomyelitis, joint, skin and soft tissue infection, biliary tract infection, bacteremia, etc. caused by gram-positive cocci such as sensitive Staphylococcus aureus and anaerobic bacteria.
