② white silk disease was sprayed 1000 times in the base of the plant and the surrounding soil at the initial stage of the disease, and then sprayed again after 7-10 days. After that, 1000-fold solution of 70% thiophanate wettable powder, or 1000-fold solution of carbendazim, or 3000-fold solution of Luheng No. 1, or Luheng No. 2 were used to irrigate the rhizosphere soil to restrain the spread of the disease. After the seriously diseased plants are removed, the acupoints can be irrigated with 500 times of 50% Dysenamine water agent, or the disease points can be sprinkled with lime powder to disinfect the soil. Potted plants can be changed in time, and the cultivated soil (potted soil) and plants should be disinfected with 3000 times liquid of Luheng No.1. After putting on the pot, the site should be changed, and the pot plants should be maintained in a place with plenty of sunshine and air circulation.
③ anthracnose, timely removal of diseased leaves, diseased tips and destruction, foliar spraying 75% chlorothalonil wettable powder 1000 times, 12% green copper EC 600,800 times, 70% methyl thiophanate wettable powder 1000 times, 60% anthrax Fumei wettable powder 800 times, etc., choose one or more kinds of alternate use, spray every 5-7 days, spray 4-6 times according to the disease.
2. Insect pests

② red spider can be sprayed with 3000 times of Nisolang emulsion, 1500-2000 times of omethoate emulsion, 2000 times of 73% paracetamol EC, etc., and two or more agents are used alternately every 5 days or so.
③ aphids can be sprayed with 3000 times of 50% aldicarb (aphid mist) wettable powder or 10000-20000 times of imidacloprid wettable powder.

Storage of finished jasmine tea
The main factors affecting the quality of jasmine tea during storage are temperature and water content, oxygen and light. In general, the greatest influence is tea water content. Followed by temperature and oxygen, while light is easier to control. In general, the moisture content of finished tea products should be kept below 5%, then the quality will change slowly. The moisture content of finished jasmine tea is close to 8%. Therefore, it is more sensitive to humidity, and the relative humidity of the surrounding environment directly affects the moisture absorption rate of tea. So bulk jasmine tea is best stored in
