What diseases and insect pests should be prevented from growing rich trees?

Which diseases and insect pests should be prevented and controlled by raising wealth trees? Please introduce the prevention and control methods as follows: first, root (stem) rot is a common disease that seriously harms the rich tree, also known as rot. Prevention and control methods: (1) keep the cultivation environment dry and pay attention to the disinfection of cultivation media and sites; (2) after the semi-finished products are unloaded to the operating shed, the head of the rich tree is sprayed with Sukeling to prevent the harm of Botrytis cinerea; (3) cut off the sprained and rotten tissue at the top of the main root with a sharp knife before planting, and then spray the wound with Sukeling, and then plant it after drying. (4) after a week of planting, the medium in the basin dries gradually, the healing tissue has been formed, and the new root has begun to grow. It is advisable to spray the smooth rod of the wealth tree with pluck, Anke or zinc and manganese (Redomir-manganese zinc) to flow into the basin soil along the pole. After that, the fungicides were rotated once a week with Anke, carbendazim, Remicol or Phytophthorin. (5) if Pythium is active, spray it with Prik, carbendazim, Redomir or Phytophthorin, and the general efficacy is about two weeks. If the weather is still bad, different chemicals should be sprayed to prevent the development of drug resistance. If festering plants are found during this period, they should be discarded immediately. 2. Leaf blight control methods: (1) timely removal of diseased leaves and destruction; (2) maintenance and management should be strengthened during the cultivation of rich trees, timely watering and fertilization, and foliar fertilizer can be applied for 2 times per growing season, such as 0.5% potassium dihydrogen phosphate or 200 times of double-effect micro-fertilizer. (3) before the seedlings are transported from the south to the north, protective fungicides are sprayed on the leaves, such as 70% chlorothalonil 800 times, or 18% multi-fungus copper milk powder 200 times, or 50% bacillus 600 times. After being transported to the north, it should be planted in time, strengthen fertilizer and water management, and prevent dehydration and de-fatting. The cultivation of rich trees in the south can start from the rainy season, spraying 50% carbendazim 800x solution, or 70% chlorothalonil 800x solution, 75% methyl thiophanate 1500 times solution every 10 seconds for 15 days. In addition, the main pest is the sugarcane flat moth, which is a new record in China, mainly because the larvae harm the rich tree, as well as poinsettia, flutung, goose palm wood and Hawaiian coconut.
