The control of pests and diseases after the fall of apples should be combined with the prevention and control of key pests throughout the year. The main pests and diseases are: apple aphid, golden moth, spotted leaf disease, mildew disease and deficiency syndrome. The pests and diseases that need to be controlled by pesticides after falling flowers in apples include apple leafhoppers and ringworms.
1. Apple cotton. About 17 generations occur each year, and the larvae of the 1st and 2nd instars overwinter in the rough middle and lower parts of the tree and in the soil near the main trunk. The activities begin in mid-April and begin to spread in early May. There are two hazard peaks in June and September. . After the apple falls, it is suitable for prevention and treatment. The commonly used medicaments are 48% 1500 times solution, 10% imidacloprid 2000 times solution, 5% acetamiprid 2000 times solution and compound preparation. Focus on spraying the trunk.
2. Gold-colored moths. About 5 generations per year, the wintering of the worms in the leaves, the wintering adults in the early April, and the end of April after the apples fall, the adult generations of the next generation are in early June, early July, early August, Mid-to-late September. The adult is in the late stage of prevention and control. The commonly used agents are 50% insecticide phoxim 1000 times solution, 25% chlorfenapyr 3 1500 times solution, 20% fenvalerate 2000 times solution. Focus on the back of the leaf.
3. Apple leafhopper. There are three species of spider mites: the mountain plant leafhopper, the apple full claw cockroach, and the two scutellaria. Hawthorn leafhopper occurs 6 to 10 generations a year, and the female adult worms overwinter on the apple trunk. After the apple falls, the apple climbs to the back of the new stalk of the tree, which is neat and small. Apple's whole claws occur 6 to 7 generations a year, and the eggs are overwintered on the branches of the year. After the apples fall, the second generation of nymphs has appeared. The occurrence of the two-spotted spider mite is similar to that of the mountain leafhopper. After the fall of the apple, the main control agents are Ruoqiang and Chengyu. The commonly used medicaments include 15% Qiling 2000 times solution, 1.8% avermectin 3000 times solution and compound preparations.
4. Mildew. According to the China Pesticide Network , it mainly occurs in the Red Star series. The pathogen is strong, and it is wintering in various places such as orchard trees or weeds. It invades during flowering, and the fruit matures and shows symptoms after harvesting. Prevention and treatment of mildew disease can use 400% sulfur suspension agent 400 times solution at the initial flowering stage, 10% polyoxytetracycline (Polyan) 1500 times liquid during the flowering period, 50% carbendazim 500 times solution or 40% Fuxing after the flowering 8000 times liquid, etc.
5. Spotted deciduous disease. Mainly occurs in the Red Star series. The pathogens overwinter on the damaged leaves, shoots, and buds of the hyphae, invade the branches at a rapid rate, and can infect multiple times. After the apple is flowered, it can be controlled with 10% polyoxytetracycline (Polylia) 1500 times solution, 50% chlorhexidine 1200 times solution, and 80% mancozeb 800 times solution.
6. Ring disease. Mainly occurs in the Fuji series. The pathogens overwinter on the trunk, and spores are scattered after the spring temperature rises, invading the branches. Rotational disease is a key disease of apples. Regular prevention and control should be carried out, especially in the early and middle stages. Commonly used agents are 80% mancozeb 800 times solution, 70% fungicide methyl thiophanate 800 times solution, 80% ethyl phosphate aluminum 600 times solution, 50% carbendazim 500 times solution, 40% Fuxing 8000 times solution Wait.
7. Black spot disease. It only happens on the bagged fruit. The pathogens overwinter on the diseased fruit and diseased leaves, and 10 to 30 days after the flowering is the same as the prevention and treatment of the infection.
The Peristaltic Pump can be used in liposuction surgery, in the process of swelling anesthesia, used to deliver saline.
The definition of swollen anesthesia is to infiltrate into subcutaneous adipose tissue by ultra-low concentration, high-dose, a large-volume local anesthetic (currently used lidocaine) as an anesthetic method for liposuction.
Swelling anesthesia was first proposed by Klein in 1987. It is also called [over-perfusion anesthesia". A large amount of solution containing adrenal and lidocaine is stably perfused into the skin through a peristaltic pump, causing edema and cell tissue gap in the subcutaneous tissue and its structure. The small blood vessels are separated and pressed to be locked, thereby achieving the effects of local anesthesia, pain relief, hemostasis, and tissue separation.
Swollen anesthesia can be used as separate local anesthesia or combined with general anesthesia or regional anesthesia.
The advantage of peristaltic pump in swelling anesthesia:
1, easy operated, non-contamination
2, foot pedal control ,safety & reliability
3, adjustable speed and left/right direction optional
4, Power-down memory function
