A letter from a reader from Hou Zhilan, Manzhouli City, Inner Mongolia asked: I am raising African jasmine and I do not know why something sticky like an oil drop has appeared on the stick and land on the ground. Will it affect the growth of flowers and trees? What should I do? A: The real name of "African Jasmine" should be Hua Lili. It is a woody foliage plant of the genus Moneyaceae and Ashley. It is native to China's Guangdong, Guangxi, Hainan, Yunnan, Hong Kong and Taiwan, India, and Sri Lanka. , Myanmar, Thailand, Vietnam, Laos, Cambodia, Indonesia and other countries also have distribution. Its branches and leaves appear to be as thick as oil droplets, and their tongues are sweet. They are the honeydew, scale insects, whiteflies, etc., which are secreted by honeyworms. They are the sugars excreted from the anus by these three types of insects. Liquids can attract ants and other insects, and provide "natural media" for the occurrence of coal pollution. With honeydew as the lead, coal-polluted bacteria will multiply and multiply, resulting in black and dirty coal and dirt on the leaves and branches. If poor ventilation and poor light are added, pests and diseases will be superimposed. Seriously affect the growth and appreciation of the plant. Control methods: 1 strengthen ventilation and light, improve environmental conditions, and increase plant resistance. 2 If it is a locust infestation, sprinkle a layer of soot or plant ash on the plants, rinse with water after a few hours, or spray with 20% of the 10% imidacloprid wettable powder. 3 If scale insects and whiteflies are harmful, use 25% of buprofezin WP to spray 1500 times. After the pests have been eliminated, the "greasy" leaves no longer appear on the branches and leaves.
